交通ルールアイルランド
1. アイルランド
アイルランドは北西ヨーロッパの島国で、アイルランド島の大部分を占め、北アイルランドと陸上国境を接しています。交通は左側通行で、国境の北アイルランドとは異なり速度制限はマイル毎時ではなくキロメートル毎時で表示されます。主要高速道路や国道を離れると、生け垣や石垣に囲まれた狭い地方道が多く、視界が限られ、1台分の幅しかない区間もあります。
アイルランドにはアイルランド語と英語の2つの公用語があり、方面・地名標識では両方が一般的に使われます。アイルランド語が地域社会の言語として残るゲールタハトでは、公式地名がアイルランド語のみで表示されることがあります。高速道路ヴィネットはありませんが、複数の高速道路、橋、トンネルが有料です。また2025年には、多くの地方ローカル道路の既定速度制限が80 km/hから60 km/hへ引き下げられました。
アイルランドでは道路のどちら側を走りますか?
左側を走行し、通常は右側から追い越します。
アイルランドで緊急時に電話する番号は何ですか?
緊急の警察、救急車、消防、沿岸警備は999または112へ電話します。
アイルランドの法定飲酒運転基準はどのくらいですか?
通常の本免許運転者の血中アルコール濃度上限は血液100 mlあたり50 mgです。学習運転者、初心運転者、職業運転者には、より低い20 mg/100 mlが適用されます。
アイルランドの市街地の一般速度制限は何km/hですか?
別の標識がない限り都市部の一般最高速度は50 km/hです。住宅地、町の中心部、学校周辺などでは30 km/hなど低い制限が増えています。
アイルランドの地方ローカル道路の速度制限は何km/hですか?
2025年2月以降、多くの地方ローカル道路の既定最高速度は80 km/hから60 km/hへ引き下げられました。これらは一般にL番号の道路、または番号のない道路で、常に標示された速度制限に従います。
アイルランドの地域道路の一般速度制限は何km/hですか?
別の標識がない限り地域道路の一般最高速度は80 km/hです。
アイルランドの国道の一般速度制限は何km/hですか?

アイルランドの高速道路の最高速度は何km/hですか?
乗用車の高速道路での一般最高速度は、別の標識がない限り120 km/hです。
アイルランドの速度制限はマイル表示ですか、キロメートル表示ですか?
アイルランドの道路速度と現行速度標識はキロメートル毎時(km/h)を使用します。北アイルランドへ越境するとマイル毎時表示へ変わります。
アイルランドの高速道路にはヴィネットが必要ですか?
いいえ。全国共通の高速道路ヴィネットはありません。大半の道路は無料ですが、複数の高速道路、橋、トンネルで通行料金がかかります。
ダブリンのM50通行料金はどのように支払いますか?
M50のジャンクション6と7の間ではバリアのない電子料金徴収を使用し、料金所はありません。登録済み料金口座やタグがない運転者は、通常有料区間を利用した翌日の20:00までに支払う必要があります。
アイルランドでは乗用車も昼間にヘッドライトを使う必要がありますか?
通常の昼間にすべての乗用車へロービームを義務付ける一般規則はありません。装備車ではデイタイムランニングライトが自動点灯する場合があり、Road Safety AuthorityはDRLがない車両では昼間のロービーム使用を推奨しています。
アイルランドでは冬用タイヤが義務ですか?
いいえ。特定季節に冬用タイヤを装着する一般的な法的義務はありません。ただしタイヤが道路走行に適した状態であることを確保し、氷、雪、雨などに応じた運転を行う必要があります。
アイルランドではシートベルトが義務ですか?
限定的な法的免除を除き、装備されている場合は運転者と乗客にシートベルト着用が義務です。
アイルランドで子どもがチャイルドシートを使用しなければならないのはいつですか?
特定の例外を除き、身長150 cm未満または体重36 kg未満の子どもは、乗用車や貨物車で移動する際に適切なチャイルドシートを使用します。
アイルランドで後ろ向きチャイルドシートを作動中のエアバッグ前に設置できますか?
いいえ。後ろ向きチャイルドシートを作動中の前面エアバッグの前へ設置してはいけません。その位置に設置する前にエアバッグを無効化する必要があります。
アイルランドでオートバイ用ヘルメットを着用しなければならないのは誰ですか?
オートバイの運転者と同乗者は、走行中いつでも正しく締めた認可クラッシュヘルメットを着用しなければなりません。
アイルランドでは自転車利用者にヘルメット義務がありますか?
いいえ。普通自転車の利用者に一般的な法的ヘルメット義務はありませんが、Road Safety Authorityは着用を強く推奨しています。
アイルランドで運転中に手持ちの携帯電話を使えますか?
いいえ。運転中に携帯電話を手に持つことは違法です。許可されたハンズフリー機器を使う場合でも、運転者は車両を適切に制御し続けなければなりません。
アイルランドのラウンドアバウトでは誰が優先ですか?
別の標識、路面表示、信号がない限り、進入時は一般に右から来る交通またはすでにラウンドアバウト内にいる交通へ道を譲る必要があります。
アイルランドの横断歩道で運転者は何をしなければなりませんか?
ゼブラ横断歩道では、横断待ちまたはすでに横断を始めた歩行者へ道を譲る必要があります。安全に停止できる速度で接近します。
アイルランドで自転車を追い越す際、どのくらい間隔を空ける必要がありますか?
速度制限50 km/h以下の区域では少なくとも1 m、50 km/hを超える区域では少なくとも1.5 mを空けます。
アイルランドで学習運転者は高速道路を走れますか?
いいえ。カテゴリーBの学習運転者は高速道路を運転できません。Lプレートを表示し、同じカテゴリーの本免許を2年以上保有する有資格運転者の同乗も必要です。
アイルランドの初心運転者にはどのような規則が適用されますか?
最初の本免許取得後2年間、初心運転者はNプレートを表示します。また、より低い血液100 mlあたり20 mgの飲酒運転上限と、免許取消しに至る低い違反点数基準が適用されます。
アイルランドの信号で赤と黄は何を意味しますか?
赤は停止を意味します。黄も停止を意味し、停止線を越えてはいけません。ただし信号が変わった時点ですでに近すぎて停止すると危険になる場合は例外です。
アイルランドの高速道路で通常、路肩を走行できますか?
いいえ。高速道路の路肩は緊急時だけ使用します。故障した場合は可能なら路肩へ移動し、救援を求め、バリアの後ろなど安全な場所で待ちます。
アイルランドの乗用車にはどのような安全装備を携行すべきですか?
Road Safety Authorityは警告三角表示板、救急セット、消火器、予備電球セットの携行を推奨しています。これらは自家用乗用車に一般的な義務装備一式ではなく、推奨安全用品です。
2. 高速道路
高速道路は、自動車交通のために特別に設計され、標識で指定された道路です。通常、対向交通用の車道が分離され、指定された出入口によるアクセス制御があり、沿道施設への直接出入りや、他の道路・鉄道・通路との平面交差はありません。
高速道路では特別な交通規則が適用されます。利用できる道路利用者、速度制限、車線規則、通行料金、緊急時の手順は国によって異なるため、運転者は現地の交通標識と規則に従う必要があります。
How can you recognise a motorway?
A motorway is normally identified by a special motorway sign at its entrance. It commonly has separate carriageways, controlled entrances and exits, and no ordinary intersections or direct access to neighbouring properties.
Who may use a motorway?
Motorways are primarily intended for motor vehicles capable of travelling safely at motorway speeds. Pedestrians, cyclists, animals and certain slow vehicles are generally prohibited, but the exact access requirements differ between countries.
What is the speed limit on a motorway?
There is no universal motorway speed limit. The applicable limit depends on the country, road section, vehicle category and driving conditions. Posted or variable speed-limit signs may replace the general national limit.
How should you enter a motorway?
Use the entrance or acceleration lane to observe motorway traffic and adjust your speed where possible. Enter only when there is a safe gap and follow the local priority and merging rules.
How should you leave a motorway?
Move into the correct lane in good time and signal when required. Enter the exit or deceleration lane before reducing your speed, unless traffic, signs or road conditions require you to slow down earlier.
Which lane should you use on a motorway?
Follow the local keep-left or keep-right rule and any lane-direction signs. Lanes closer to the centre of the motorway are commonly used for overtaking, but lane-use rules differ between countries and vehicle categories.
Can you stop on a motorway?
Voluntary stopping and parking are normally permitted only in designated parking or service areas. Drivers may still have to stop because of congestion, an emergency or another unavoidable situation.
Can you reverse or make a U-turn on a motorway?
Reversing, making a U-turn and driving against the direction of traffic are generally prohibited. If you miss an exit, continue to the next suitable exit.
What should you do if your vehicle breaks down?
Move the vehicle out of the traffic lanes when this can be done safely, activate the hazard warning lights and follow the local breakdown procedures. Leave the vehicle safely, keep away from moving traffic and use a warning triangle or safety vest where required by local law.
What is the difference between a motorway and an expressway?
A motorway normally has the highest level of access control and is governed by specific motorway rules. An expressway may have similar characteristics but may permit different road users or contain lower-standard junctions. The legal distinction varies between countries.
3. 住宅地域
住宅地域は、住宅や地域内の敷地への出入りが主な機能となる道路または道路群です。運転者は歩行者、自転車、子ども、駐車車両、車庫や私有地から出入りする車両を想定する必要があります。
国によっては特定の住宅地域を標識で指定し、低速や共有空間に関する特別規則を適用します。そのため速度制限、歩行者の権利、駐車規則、通行可能な道路利用者は現地の標識と規則に従います。
How can you recognise a residential area?
A residential area commonly contains homes, driveways, parked vehicles and local streets. It may also have special entrance signs, traffic-calming measures or shared road space, but its appearance and legal status differ between countries.
Is a residential area the same as a built-up area?
Not necessarily. A built-up area may include residential, commercial and industrial streets. A residential area is primarily associated with housing and local access and may form only one part of a larger built-up area.
Is every residential neighbourhood a legally designated residential zone?
No. In many countries, special residential-zone rules apply only where an official entrance sign is displayed. An ordinary neighbourhood may remain subject to the normal rules for the surrounding road or built-up area.
What is the speed limit in a residential area?
There is no universal residential-area speed limit. Some countries apply a very low limit in signposted residential or shared-space zones, while ordinary residential streets may follow the general built-up-area limit or a posted zone limit.
Do pedestrians have priority in a residential area?
The rights of pedestrians depend on the country and the type of residential area. In some signposted shared-space zones, pedestrians may use the whole road and drivers must give them special consideration. On ordinary residential streets, the normal pedestrian and crossing rules may apply.
May children play in a residential area?
Playing may be expressly permitted in certain legally designated residential or shared-space zones. This is not automatically allowed on every residential street. Drivers should nevertheless remain especially alert for children, who may enter the road unexpectedly.
Which road users may enter a residential area?
Residential areas are normally accessible to local motor traffic, cyclists and pedestrians, but additional signs may restrict certain vehicles or through traffic. A residential area is therefore not necessarily a pedestrian-only zone.
How should you drive in a residential area?
Drive at a speed that allows you to stop safely, watch both sides of the road and expect pedestrians, cyclists, children, pets and vehicles emerging from entrances. Leave enough space and avoid unnecessary acceleration, noise or aggressive overtaking.
May you overtake in a residential area?
Overtaking is not universally prohibited, but it may be restricted by local law, signs or road design. Even where it is permitted, drivers should not overtake when the limited space or presence of vulnerable road users makes it unsafe.
Where may you park in a residential area?
Follow the local parking signs, markings and general parking rules. Do not block entrances, pavements, crossings, sight lines or the passage of other road users. Special residential zones may permit parking only in designated spaces.
What is the difference between a residential area and a pedestrian zone?
Motor vehicles are normally still permitted in a residential area, although they may be subject to strict speed and parking rules. In a pedestrian zone, vehicle access is generally prohibited or limited to specific users, purposes or times.
4. ゾーン
交通ゾーンは、含まれるすべての道路または道路区間に特定の交通規則が適用される区域です。規則は通常、ゾーン開始標識から始まり、対応するゾーン終了標識を通過するまで有効です。
ゾーンでは速度、駐車、進入、車種、排出ガス、その他の交通行動を規制できます。使用する標識、対象道路、交差点や例外の扱いは現地の交通法規によって異なります。
What is a traffic zone?
A traffic zone is a defined area in which a particular restriction, prohibition or obligation applies throughout the included roads rather than only at one location.
How can you recognise a traffic zone?
A traffic zone normally begins with a zone-entry sign showing the applicable rule. A corresponding end-of-zone sign indicates where that rule stops applying.
What is the difference between a zone sign and an ordinary traffic sign?
An ordinary sign usually applies to a particular road, direction, lane or section. A zone sign applies throughout a designated area, which may contain several roads and intersections.
Does a zone normally continue after an intersection?
Usually, yes. A zonal rule commonly continues through intersections until an end-of-zone sign is reached. The exact effect of intersections depends on local law.
How does a traffic zone end?
A traffic zone normally ends when you pass the corresponding end-of-zone sign. The normal road rules or another signed regulation then apply.
Can more than one rule apply inside a zone?
Yes. A zone may contain several regulations, such as a speed limit together with parking or access restrictions. Drivers must observe every applicable sign.
Can another traffic sign apply inside a zone?
Yes. A local sign may introduce a different or more restrictive rule on a particular road or section. Whether the original zonal rule resumes afterwards depends on local law and the type of regulation.
What types of traffic zones exist?
Common examples include speed zones, parking zones, low-emission zones, pedestrian zones, cycling zones, school zones and zones restricting particular vehicle categories.
Is a traffic zone the same as a built-up area?
No. A built-up area is a broader legally defined urban area. A traffic zone imposes a specific signed rule and may be located inside or outside a built-up area.
Is a traffic zone the same as a residential area?
No. A residential area describes an area mainly used for housing. It may contain one or more traffic zones, but the terms do not automatically have the same legal meaning.
Does a zonal rule apply to every road user?
Not necessarily. The sign, symbol or additional panel may limit the rule to particular vehicles, road users, times or circumstances.
What should you do when entering a traffic zone?
Observe the entrance sign carefully, identify every displayed rule and remember that the regulation may continue across several roads and intersections until the zone ends.
5. 速度制限
速度制限は、道路、車線、または指定区域で法律上許可される最高速度です。一般交通法規によって定められる場合も、固定式・可変式・一時的な標識で示される場合もあります。
速度制限は上限であり、目標速度ではありません。交通、視界、天候、路面状況、交通弱者、車両状態などにより上限速度が安全でない場合、運転者はさらに減速する必要があります。
What is a speed limit?
A speed limit is the maximum legal speed permitted on a road, lane or within a designated area. It does not require drivers to travel at that speed.
How can you recognise a speed limit?
A speed limit is commonly displayed as a number on a regulatory traffic sign. General limits may also apply automatically because of the country, road category, vehicle type or surrounding area, even when no speed-limit sign is present.
Is the speed limit a recommended driving speed?
No. It is the highest speed legally permitted under suitable conditions. Drivers must reduce their speed whenever travelling at the limit would be unsafe.
Can you drive more slowly than the speed limit?
Yes. Drivers should travel more slowly when required by traffic, weather, visibility, road conditions or nearby vulnerable road users. Driving unnecessarily slowly may nevertheless be prohibited when it obstructs normal traffic.
Does the same speed limit apply to every vehicle?
Not always. Lower limits may apply to heavy vehicles, buses, vehicles towing trailers, novice drivers or other vehicle categories. The lowest applicable limit must be respected.
What is a default speed limit?
A default speed limit applies automatically to a particular road type or area when no traffic sign indicates another limit. Examples include general limits for motorways, built-up areas or roads outside built-up areas.
Does a posted speed limit replace the default limit?
Usually, yes. A legally placed speed-limit sign normally introduces another maximum speed, although lower vehicle-specific or special-road limits may continue to apply.
When does a speed-limit sign take effect?
A speed restriction normally begins at the location of the sign. Drivers should reduce their speed before passing the sign so that they are already travelling within the limit when it takes effect.
When does a speed limit end?
A signed limit may end at an intersection, an end-of-limit sign, another speed-limit sign or the beginning or end of a legally defined area. The exact rule differs between countries.
Does an intersection end a speed limit?
This depends on local law. An ordinary speed restriction may end at an intersection in some countries, while a zonal speed limit normally continues across intersections until an end-of-zone sign.
What is a speed zone?
A speed zone is an area in which the displayed maximum speed applies throughout all included roads. The limit normally remains in force until the corresponding end-of-zone sign.
What is a variable speed limit?
A variable speed limit is displayed on an electronic or changeable sign and may be adjusted according to congestion, weather, incidents or roadworks. When activated, it has the same legal importance as another applicable regulatory speed sign.
Can different lanes have different speed limits?
Yes. Signs positioned above individual lanes may impose different limits on those lanes. Drivers must observe the limit applying to the lane they use.
Can a temporary speed limit apply?
Yes. Temporary limits may be introduced near roadworks, collisions, hazards or special events. Drivers must follow the temporary traffic signs and instructions that are legally in force.
May you exceed the speed limit while overtaking?
No. Overtaking does not normally permit a driver to exceed the applicable maximum speed. The manoeuvre must be completed safely while respecting the speed limit.
Do poor conditions change the legal speed limit?
Some countries impose specific lower limits in rain, snow or other conditions. Even where the numerical limit does not change, drivers must reduce their speed sufficiently for the conditions.
6. 自転車道
自転車道は、主にまたは専ら自転車利用者のために設けられた道路の一部または独立した通路です。自動車交通から物理的に分離される場合、路面標示で示される場合、標識で指定される場合があります。
自転車道には一方通行、双方向、他の道路利用者との共用があります。利用可能者、進行方向、優先規則、利用義務は現地の交通標識と規則に従います。
How can you recognise a bike path?
A bike path may be identified by a bicycle traffic sign, bicycle symbols, coloured surfacing or road markings. It may run beside the carriageway or follow a completely separate route.
Is a bike path the same as a bike lane?
Not always. A bike lane is normally marked directly on or beside the carriageway, while a bike path may be physically separated from motor traffic. The terminology and legal distinction vary between countries.
Must cyclists use a bike path?
This depends on local law and the signs displayed. Some bike paths are mandatory, while others are optional. Cyclists may also be permitted to leave a path to turn, overtake or avoid an obstruction.
Can a bike path carry traffic in both directions?
Yes. Some bike paths are two-way, but others may be used only in the direction indicated by signs, markings or their position beside the road. Cyclists should not assume that every path permits travel in both directions.
May pedestrians use a bike path?
Pedestrians may use a bike path where it is designated as a shared-use path or where local law permits it. On a cycle-only path, pedestrians may be prohibited or permitted only when no suitable pedestrian facility is available.
May mopeds or speed pedelecs use a bike path?
This depends on the country, vehicle category, road speed and traffic signs. Some bike paths permit or require certain mopeds or speed pedelecs, while others are reserved exclusively for ordinary bicycles.
May motor vehicles use a bike path?
Normally not. Motor vehicles may cross a bike path to enter another road or property where this is permitted, but they must follow the applicable priority rules and must not endanger path users.
Who has priority where a vehicle crosses a bike path?
Priority depends on the road layout, signs, signals and local law. Drivers crossing a continuous bike path commonly have to give way to its users, but cyclists approaching a separate cycle crossing may not automatically have priority before entering it.
Does a cyclist always have priority at a cycle crossing?
No. A marked cycle crossing does not universally give an approaching cyclist priority. Cyclists should enter cautiously and observe approaching traffic unless signs, signals or local rules clearly give them priority.
Is there a speed limit on a bike path?
Some countries or local authorities impose specific limits, particularly on shared paths. Even without a posted limit, cyclists must travel at a safe and considerate speed for the width, visibility and number of other users.
May you stop or park on a bike path?
Normally not. Stopping or parking on a bike path can force cyclists into motor traffic and may be expressly prohibited by law.
What should cyclists do when passing pedestrians?
Reduce speed, give a clear warning where appropriate and leave sufficient space. Pedestrians may change direction unexpectedly, especially on a shared path.
What should cyclists do when a bike path is blocked?
Slow down and check surrounding traffic before leaving the path. Avoid the obstruction safely and return to the bike path when permitted and practical.
Can cyclists ride side by side on a bike path?
This depends on local law and the available width. Even where riding side by side is permitted, cyclists must not block, endanger or unnecessarily hinder other path users.
What is the difference between a bike path and a shared-use path?
A bike path is intended primarily or exclusively for cycling. A shared-use path is legally intended for cyclists together with pedestrians or other indicated road users, who must use the space considerately.
7. 歩行者注意
歩行者注意は、前方で歩行者が道路を横断したり車道へ進入したりする可能性を示す警戒表示です。横断歩道付近など、歩行者が多く運転者へ事前の注意が必要な場所で使われます。
運転者は必要に応じて減速し、歩行者をよく確認し、停止できるよう備える必要があります。警戒標識のデザインや横断場所での優先規則は国によって異なります。
What does a pedestrian warning mean?
A pedestrian warning alerts drivers that pedestrians may be crossing or entering the road ahead.
Where are pedestrian warning signs commonly used?
They are commonly placed near pedestrian crossings or other locations with significant pedestrian activity.
How should you react to a pedestrian warning?
Reduce speed when necessary, watch both sides of the road and be prepared to give way or stop for pedestrians according to the applicable traffic rules.
8. 橋
橋は、道路、通路、鉄道を川、谷、鉄道路線、別の道路などの障害物の上に通す構造物です。道路橋には1本以上の車道に加え、歩道や自転車施設が設けられる場合があります。
運転者は橋に適用される速度、重量、高さ、幅、車両進入制限に従う必要があります。狭い橋、風にさらされる橋、可動橋では特に注意し、風、雨、氷などが路面に影響する場合も慎重に運転します。
What is a bridge?
A bridge is a structure that carries a road, path or railway over an obstacle such as a river, valley, railway or another road.
Can a bridge carry several traffic lanes?
Yes. Road bridges may carry one or several traffic lanes and can also contain pavements, cycle facilities or public-transport infrastructure.
Can a bridge have a weight limit?
Yes. A bridge may have restrictions on the maximum vehicle mass or axle load that it can safely accommodate. Drivers of heavy vehicles must obey the applicable signs.
Can a bridge have a width or height restriction?
Yes. Narrow bridges or structures forming part of a bridge can have width, height or other dimensional restrictions indicated by traffic signs.
What is a movable bridge?
A movable bridge is a bridge that can open, lift, swing or otherwise move to allow ships or other traffic to pass beneath or through it.
What should you do when a movable bridge is opening?
Stop when required by the traffic lights, barriers or other signals and remain behind the designated stopping point until the crossing is reopened.
Can bridges become slippery?
Yes. Bridge surfaces can become wet, icy or slippery and may sometimes cool differently from the surrounding road. Drivers should adapt their speed to the actual conditions.
Can strong winds be dangerous on a bridge?
Yes. Exposed bridges can be affected by crosswinds, particularly for motorcycles, bicycles, high-sided vehicles and vehicles towing trailers.
Can you stop or park on a bridge?
This depends on the local traffic rules, road layout and signs. Stopping or parking may be prohibited where it would create danger, obstruct traffic or reduce the available road width.
Can pedestrians and cyclists use a bridge?
Yes, where permitted. Bridges may provide pavements, cycle paths or shared facilities, while high-speed or restricted bridges may prohibit certain road users.
Can traffic be restricted to one direction on a narrow bridge?
Yes. Priority signs, traffic lights or other traffic-management measures may control which direction passes first where two-way traffic cannot safely meet.
Should you overtake on a narrow bridge?
Only when overtaking is legal and clearly safe. Limited width or visibility can make overtaking inappropriate even where no specific prohibition is shown.
9. 速度抑制ハンプ
速度抑制ハンプは、車両を物理的に減速させるため道路表面を盛り上げた交通静穏化設備です。住宅地、学校周辺、歩行者の多い場所などで使われます。
運転者はハンプへ近づく前に速度を落とし、滑らかに通過して車両や乗員への衝撃を避ける必要があります。ハンプ自体が常に特定の法定速度を示すわけではないため、掲示された速度制限にも従います。
What is the purpose of a speed bump?
A speed bump is intended to physically reduce vehicle speeds. It encourages drivers to slow down in places where pedestrians, cyclists, children or local traffic may be present.
How can you recognise a speed bump?
A speed bump is a raised section extending across all or part of the road. It may be marked with contrasting paint, road markings or warning signs to make it more visible.
Is a speed bump the same as a speed table?
No. A speed bump or speed hump normally has a rounded profile. A speed table has ramps leading to a longer, flat raised section that may contain an intersection or pedestrian crossing.
Is a speed cushion the same as a speed bump?
No. A speed cushion is a narrower raised device that does not cover the full width of a traffic lane. Its design may allow buses and emergency vehicles to pass with less disturbance while still slowing smaller vehicles.
Is there a universal speed limit over a speed bump?
No. The legal speed depends on the country, traffic signs and road type. Even when no special limit applies, drivers must cross the device at a speed that is safe for the road, vehicle and passengers.
How should you approach a speed bump?
Check surrounding traffic, reduce your speed smoothly and approach in a straight line where possible. Avoid sudden braking immediately before the bump.
Should you brake while crossing a speed bump?
Most of the necessary braking should be completed before reaching the raised surface. Cross at a steady, low speed and avoid harsh braking or acceleration while the wheels are on the device.
Should you drive across a speed bump at an angle?
Normally not. Cross in the normal direction of the traffic lane unless the road layout requires otherwise. Driving diagonally may place the vehicle in the path of approaching or overtaking traffic.
May motorcycles and bicycles use a speed bump?
Yes. Riders should reduce speed, keep the vehicle stable and cross as directly as possible. Painted or wet raised surfaces may provide less grip.
Do pedestrians have priority at a speed bump?
Not automatically. A speed bump does not by itself create a pedestrian crossing. Pedestrian priority depends on crossings, traffic signals, signs and local law.
Does a speed bump change priority at an intersection?
No. The presence of a raised surface does not normally change the priority rules. Drivers must continue to follow traffic signs, signals and the ordinary intersection rules.
May you overtake on a speed bump?
Overtaking may be restricted by local law or signs. Even where it is not expressly prohibited, drivers should avoid overtaking when the raised surface, limited space or nearby vulnerable road users make the manoeuvre unsafe.
May you stop or park on a speed bump?
This depends on local law. Stopping or parking may be prohibited because the vehicle could obstruct visibility, traffic flow or the purpose of the traffic-calming device.
Can a speed bump damage a vehicle?
A correctly designed speed bump should be crossed safely at an appropriate speed. Crossing too quickly may damage tyres, wheels, suspension, bodywork or cargo and may cause passengers discomfort.
Does the road speed limit change after a speed bump?
Not necessarily. A special limit may apply only to the raised device, while a signed speed restriction or speed zone may continue beyond it. Drivers must follow the applicable signs and local rules.
Why do buses and emergency vehicles sometimes avoid speed bumps?
Raised devices can affect passenger comfort, emergency response and large vehicles. Some roads therefore use speed tables, cushions or other traffic-calming measures designed to reduce these effects.
10. 有料道路
有料道路は、利用するため料金の支払いが必要な道路、橋、トンネル、または道路区間です。料金は建設、維持管理、運営などの費用に充てられます。
支払い方法には料金所の現金・カード、電子タグ、ナンバープレート認識、オンライン決済などがあります。利用前に料金、支払方法、期限を確認し、外国登録車に特別な登録要件がある場合は従う必要があります。
What is a toll road?
A toll road is a road or section of road for which a charge must be paid to use it. Tolls may also apply to particular bridges, tunnels or other road infrastructure.
How are road tolls paid?
Depending on the country, tolls may be paid at a toll booth, through an electronic toll system, vignette or distance-based charging system.
Do all vehicles pay the same toll?
Not necessarily. Toll rates can vary according to vehicle type, size, weight, emissions, distance travelled or the particular road being used.
11. 岸壁
岸壁は、港、運河、河川、その他の水辺に沿って設けられ、船舶の接岸や貨物・旅客の取扱いに使われる場所です。道路が岸壁沿いを通る場合、車両は水際のすぐ近くを走ることがあります。
運転者は保護柵のない水際、港湾作業、歩行者、貨物車両に注意し、速度制限や進入規制に従う必要があります。濡れた路面、強風、夜間の視界にも注意します。
What is a quay?
A quay is a constructed waterside platform or road area beside a river, canal, harbour or other navigable water. It may be used by ships, vehicles, workers, pedestrians and loading equipment.
What does a quay warning sign mean?
It warns that the road approaches or leads onto a quay, riverbank or waterside edge where a vehicle could enter the water.
Does the sign mean that the road ends at the water?
It may. The road may lead directly towards the water, turn sharply near it or continue alongside an insufficiently protected edge. Drivers must observe the actual road layout.
How should you approach a quay?
Reduce speed early, remain in full control and watch for the road edge, barriers, bends, workers, pedestrians and moving equipment. Avoid sudden steering or braking close to the water.
Is there a universal speed limit near a quay?
No. Drivers must follow the posted or general speed limit and reduce their speed further when the road is narrow, wet, poorly lit or close to an unprotected edge.
Does a quay warning sign impose a prohibition?
No. It normally warns of danger rather than prohibiting access. Additional signs, gates or local rules may restrict particular vehicles or activities.
Does the sign change priority?
No. Drivers must continue to follow traffic lights, priority signs and the normal priority rules.
May you stop or park on a quay?
This depends on local signs and regulations. Do not stop or park where the vehicle could create danger, obstruct traffic, interfere with loading operations or block emergency access.
Should you park close to the water’s edge?
Only in a clearly authorised and suitable place. Leave sufficient space from the edge, apply the parking brake securely and follow any wheel-positioning or local parking instructions.
May you overtake near a quay?
Overtaking may be legal, but it should be avoided when the road is narrow, visibility is limited or the manoeuvre would bring the vehicle close to the waterside edge.
Why can quay surfaces be slippery?
Water, algae, mud, ice, fuel, oil or material from loading operations may reduce grip. Painted markings, rails and metal surfaces may also become especially slippery when wet.
What other hazards may be present on a quay?
Drivers may encounter pedestrians, cyclists, dock workers, cranes, forklifts, railway tracks, mooring equipment, reversing trucks and unsecured edges.
Why should large vehicles take extra care?
Large vehicles need more space to turn and may have limited visibility close to the cab or trailer. Soft edges, narrow roads and nearby equipment can make manoeuvring more difficult.
May pedestrians walk on a quay?
Pedestrian access depends on local rules. Where pedestrians are permitted, drivers should expect them to move between vehicles, vessels, buildings and loading areas.
Should you reverse near a quay edge?
Reverse only when necessary and when the route is clearly visible. Use a guide where available and never rely solely on mirrors or cameras when the vehicle could approach the water.
What should you do in darkness or poor visibility?
Reduce speed, use the required lights and look carefully for reflectors, barriers, road edges and people. Water and dark surroundings can make the boundary of the road difficult to recognise.
What should you do if a barrier is open or missing?
Do not assume that the route is safe. Slow down, identify the road boundary and follow signs or instructions from authorised personnel.
What should you do if a vehicle enters the water?
Leave the vehicle as quickly and safely as possible, help passengers where possible and contact the emergency services. Do not re-enter the water or vehicle to recover belongings.
12. 勾配
勾配は、道路が上りまたは下りに傾いている程度を示します。急勾配では車両の速度、制動距離、加速、安定性、重い車両の性能に大きな影響があります。
運転者は下り坂の前に適切な速度とギアを選び、長時間ブレーキだけに頼らず、前方の交通に十分な間隔を取る必要があります。狭い坂道では上り・下り車両の優先規則が地域法で定められている場合があります。
What is a road slope?
A road slope is a section of road that rises or descends over a particular distance. It may also be called a gradient, incline or decline.
How can you recognise a steep slope?
A steep slope may be indicated by a warning sign showing an ascending or descending road. The sign may also display the gradient as a percentage.
What does a gradient of 10% mean?
A gradient of 10% means that the road rises or falls approximately 10 metres for every 100 metres travelled horizontally. It does not mean that the road is inclined at 10 degrees.
What is the difference between an ascent and a descent?
An ascent rises in the direction of travel, while a descent falls in the direction of travel. The same section of road is therefore an ascent in one direction and a descent in the other.
Does a slope warning sign impose a speed limit?
Not normally. It warns of a hazard rather than setting a numerical limit. Drivers must still respect the applicable speed limit and reduce their speed further when necessary.
How should you approach a steep descent?
Reduce speed before the descent, select a suitable gear and maintain a safe following distance. Avoid allowing the vehicle to gain excessive speed.
Which gear should you use when descending?
Use a gear that provides sufficient engine braking and helps keep the vehicle at a controlled speed. The appropriate gear depends on the vehicle, gradient and road conditions.
Should you coast downhill in neutral?
No. Coasting reduces engine braking and may make it harder to control the vehicle’s speed. Keep the transmission engaged while descending.
Why should you avoid continuous heavy braking?
Continuous braking on a long descent can cause the brakes to become excessively hot and lose effectiveness. Select a suitable gear, control speed early and use the brakes progressively when needed.
What is brake fade?
Brake fade is a reduction in braking performance caused by excessive heat. It can occur when the brakes are used continuously during a long or steep descent.
How should you drive uphill?
Select a suitable gear before the engine begins to struggle and maintain a steady speed where possible. Be prepared for heavy or low-powered vehicles travelling slowly ahead.
May a vehicle lose speed on a steep ascent?
Yes. Heavy vehicles, vehicles towing trailers and low-powered vehicles may slow considerably. Other drivers should maintain a safe distance and avoid impatient manoeuvres.
May you overtake near the top of a slope?
Do not overtake when the crest prevents you from seeing far enough ahead. Overtaking near a hilltop may also be expressly prohibited by local law, signs or road markings.
Why is visibility limited near the crest of a slope?
The road surface itself may hide approaching traffic, stopped vehicles, pedestrians or other hazards beyond the crest.
Who has priority on a narrow slope?
Some countries give priority to uphill traffic, while others rely on signs or ordinary obstruction rules. Drivers must follow local law and cooperate when passing is difficult.
How should you meet another vehicle on a narrow slope?
Reduce speed and use a passing place where available. The driver who can reverse or move aside more safely should cooperate, subject to any applicable priority signs or local rules.
How do rain, snow or ice affect a slope?
They reduce traction and make acceleration, braking and steering more difficult. Increase the following distance, use smooth controls and reduce speed before entering the slope.
Why are cyclists vulnerable on slopes?
Cyclists may travel slowly and move less steadily when climbing, while they may reach high speeds when descending. Drivers should leave sufficient space and avoid overtaking without a clear view.
How should you park on a slope?
Use the parking brake, select the appropriate gear or parking position and follow local rules concerning wheel position. Make sure the vehicle cannot roll into traffic.
Can a slope affect towing?
Yes. A trailer increases the load on the engine and brakes and may affect stability. Drivers should use a suitable gear, maintain additional distance and avoid excessive speed.
13. バス専用レーン
バス専用レーンは、主にバスなど公共交通車両のために確保された車線です。道路標示、標識、異なる舗装色などで示されます。
タクシー、自転車、オートバイ、特定車両などが利用できる場合や、時間帯によって一般車両に開放される場合もあります。進入、右左折、横断、時間帯に関する規則は標識と路面表示に従います。
What is a bus lane?
A bus lane is a lane reserved primarily for buses or other authorised public-transport vehicles. Its purpose is to help public transport move efficiently through traffic.
How can you recognise a bus lane?
A bus lane may be identified by a bus-lane sign, lane markings, coloured surfacing or the word BUS painted on the road. The markings and colours differ between countries.
Is a bus lane the same as a bus-only road?
No. A bus lane forms part of a wider road arrangement, while a bus-only road may reserve the entire road for buses and other authorised users.
Who may use a bus lane?
Buses operating authorised or scheduled services may normally use it. Other vehicles may enter only when the traffic signs or local regulations expressly permit them.
May taxis use a bus lane?
This depends on local law and the signs displayed. Some bus lanes permit licensed taxis, while others are reserved exclusively for buses.
May cyclists use a bus lane?
Cyclists may use a bus lane where signs or local law permit them. They should remain alert for large vehicles, stops, passengers and buses moving towards the kerb.
May motorcycles use a bus lane?
Only where motorcycles are expressly permitted. Permission may apply to all motorcycles, particular times or specific bus lanes.
Can a bus lane operate only at certain times?
Yes. A sign may show days or hours during which the restriction applies. Outside those periods, the lane may become available to general traffic, subject to the local rules.
Does a bus lane have a special speed limit?
Not necessarily. The normal road or posted speed limit generally applies unless a separate restriction is displayed.
May ordinary vehicles enter a bus lane to turn?
Some countries allow drivers to enter a bus lane shortly before a junction to make a turn. Drivers must follow the lane markings and enter only at the point where local rules permit it.
May you cross a bus lane?
Usually, where necessary and permitted. A driver may need to cross it at an intersection or to enter or leave a property, parking area or side road. The driver must check carefully for buses, cyclists and other authorised users.
May you use a bus lane to pass congestion?
No. An unauthorised driver may not use the bus lane simply to overtake a queue or reach the front of traffic.
May you stop or park in a bus lane?
Stopping and parking are normally prohibited unless a sign or marked bay expressly permits them. A stopped vehicle can obstruct buses and force authorised lane users into general traffic.
Do buses always have priority when leaving a stop?
Not universally. Some countries require drivers to allow a signalling bus to leave a stop, particularly inside built-up areas. Elsewhere, ordinary merging rules apply.
Does a bus lane change priority at an intersection?
No. Traffic lights, priority signs and the ordinary intersection rules continue to apply unless special public-transport signals indicate otherwise.
Can a bus lane run against the direction of general traffic?
Yes. A contraflow bus lane may carry authorised vehicles in the opposite direction from nearby general traffic. Drivers and pedestrians should check both directions before crossing.
What do special bus traffic lights mean?
Some countries use separate lights or symbols for public-transport vehicles. Only drivers authorised to use that lane should follow those signals, while other traffic follows its own lights.
What should you check before crossing a bus lane?
Check mirrors and blind spots and look for buses, taxis, cyclists, motorcycles or other authorised vehicles. Their lane may be moving even when general traffic is stationary.
How does a bus lane end?
It may end at a sign, a change in road markings, an intersection or the end of its stated operating period. Drivers should follow the lane arrows and merge safely where required.
14. 一時停止標識
一時停止標識は、運転者に指定された停止位置で完全に停止することを求める規制標識です。停止線がある場合はその手前、なければ交差点や見通しを確保できる位置で停止します。
停止後、運転者は優先権のある交通や歩行者に道を譲り、安全を確認してから進みます。標識の文字や形状は国によって多少異なります。
What does a stop sign mean?
A stop sign requires a driver to come to a complete stop and give way before proceeding.
How can you recognise a stop sign?
A stop sign is commonly a red octagonal sign displaying the word STOP. Some countries use another legally recognised design, so drivers must learn the signs used locally.
Must you stop when no other traffic is visible?
Yes. The obligation to stop applies even when the road appears completely clear.
What is a complete stop?
A complete stop means that the vehicle has ceased moving entirely. Merely slowing down or allowing the vehicle to continue rolling does not satisfy the requirement.
Where should you stop?
Stop before the stop line where one is provided. Without a line, stop at the legally prescribed position before entering the intersection, crossing or priority road.
May you stop beyond the stop line?
No. The required first stop must be made before the line. If visibility is limited, move forward cautiously after stopping and stop again where necessary before proceeding.
Must every vehicle in a queue stop separately?
Yes. Each driver must make an individual complete stop. Following another vehicle through without stopping is not permitted.
Does stopping give you priority?
No. After stopping, you must continue to give way to all road users who have priority.
Who must you give way to?
Give way to traffic on the road being entered or crossed and to pedestrians, cyclists or other road users who have priority under the applicable rules.
What is the difference between a stop sign and a give-way sign?
A stop sign always requires a complete stop. A give-way sign requires the driver to yield but normally allows continued movement when the road is clearly free.
May you turn after stopping?
Yes. After stopping and giving way, you may turn in any direction permitted by signs, signals, lane arrows and road markings.
May you turn right at a red traffic light after stopping?
This depends entirely on local law and traffic signs. A stop sign does not by itself permit a turn against a red light.
Does a stop sign impose a speed limit?
No. It imposes a stopping and yielding obligation. The normal posted or general speed limit remains applicable before and after the intersection.
Does a stop sign apply to cyclists?
In many countries, cyclists are drivers and must stop unless a specific sign or local rule provides an exception.
What happens at an all-way stop?
The order in which drivers may proceed depends on local rules, commonly involving arrival order, vehicle position and turning direction. Drivers should communicate cautiously and never assume another driver will yield.
What if two vehicles stop at the same time?
Apply the local priority rule and proceed only when the intentions of the other driver are clear. Avoid forcing the other vehicle to brake or change direction.
Do traffic lights override a stop sign?
Where functioning traffic lights control the same movement, they commonly take precedence over the stop sign. Local rules determine what applies when the lights are switched off or flashing.
Do instructions from a police officer override a stop sign?
Yes. Instructions from an authorised traffic officer normally take precedence over traffic signs and ordinary priority rules.
Can a temporary stop sign be legally binding?
Yes. A correctly placed temporary stop sign at roadworks, an event or another temporary traffic arrangement must be obeyed.
What should you do when the stop sign is partly hidden?
If you recognise that a stop sign applies, reduce speed and obey it. Report damaged, obscured or missing signs to the responsible road authority where appropriate.
15. 譲れ
譲れ標識は、運転者に速度を落とし、必要に応じて停止して、優先権を持つ道路利用者へ道を譲ることを求めます。一般に逆三角形の標識が使われます。
必ず完全停止する必要はありませんが、安全に進めない場合は停止しなければなりません。どの交通に譲るかは交差点の構造、標識、現地の優先規則によって決まります。
What does a give-way sign mean?
A give-way sign requires drivers to allow traffic with priority to proceed first. The driver must slow down and stop when necessary.
How can you recognise a give-way sign?
It is commonly an inverted triangular sign with a red border and a light-coloured centre. In some countries, it is called a yield sign.
Must you always stop at a give-way sign?
No. You must stop only when necessary to give way or obtain a sufficiently clear view. You may continue slowly when the road is clearly free.
What does giving way mean?
Giving way means allowing another road user to continue without being forced to brake, accelerate, stop or change direction because of your movement.
Where should you stop when necessary?
Stop before the give-way line where one is provided. Without a line, stop before entering the intersection or priority road at a position where you can observe traffic safely.
May you cross the give-way line before stopping?
You may move beyond the line only when this does not interfere with traffic that has priority. Where visibility is limited, first slow or stop at the line and then move forward cautiously.
What is the difference between give way and stop?
A stop sign always requires a complete stop. A give-way sign permits the driver to continue without stopping when the road is clearly free and it is safe to proceed.
Does slowing down satisfy the give-way requirement?
Only when slowing down is sufficient to let all priority traffic proceed safely. If another road user would be hindered, the driver must slow further or stop.
Who must you give way to?
Give way to traffic travelling on the road being entered or crossed and to any pedestrians, cyclists or other road users who have priority under the applicable rules.
Does giving way apply only to vehicles approaching from one direction?
No. Check every direction from which lawful traffic may approach, including cycle paths, one-way roads with authorised contraflow traffic and separate carriageways.
Does a give-way sign give the other road permanent priority?
The sign determines priority at the particular location. The priority arrangement at later intersections may be different unless the road is separately identified as a priority road.
Does giving way give you priority afterwards?
No. You may proceed only when it is safe. Another driver’s hesitation or courtesy does not remove your responsibility to avoid danger.
Must every vehicle in a queue give way separately?
Yes. Each driver must observe the road and make an individual decision. You may not follow another vehicle through without checking that the way remains clear.
Does a give-way sign apply to cyclists?
Normally, yes. Cyclists are generally treated as drivers and must obey the sign unless a supplementary sign or local rule provides otherwise.
Can a give-way sign apply only to cyclists?
Yes. Some countries use supplementary signs or path-specific signs to require cyclists to give way while other traffic follows a different priority arrangement.
Does a give-way sign change the speed limit?
No. It regulates priority rather than speed. Drivers must still approach slowly enough to observe traffic and stop when necessary.
Does a give-way sign change turning rules?
No. Drivers must still obey traffic lights, lane arrows, mandatory-direction signs and turning prohibitions.
How does give way work at a roundabout?
Many roundabout entrances have give-way signs requiring entering traffic to yield to vehicles already circulating. Drivers must follow the actual signs because roundabout priority rules differ between countries.
Do traffic lights override a give-way sign?
Functioning traffic lights commonly take precedence over priority signs controlling the same movement. The give-way sign may apply again when the lights are switched off or flashing, depending on local law.
Do police instructions override a give-way sign?
Yes. Instructions from an authorised traffic officer normally take precedence over traffic signs and ordinary priority rules.
What should you do when visibility is limited?
Reduce speed substantially and stop when necessary. Move forward cautiously only after giving way and checking that the road can be entered without danger.
16. ラウンドアバウト
ラウンドアバウトは、中央島の周囲を一方向に循環し、複数の道路が接続する交差点です。進入交通の速度を下げ、交差点内の交錯点を減らすよう設計されています。
進入時の優先関係、車線選択、合図方法は国によって異なります。運転者は進入口の優先標識、車線矢印、路面表示に従い、退出時は歩行者や自転車にも注意する必要があります。
What is a roundabout?
A roundabout is a circular road arrangement where traffic travels in one direction around a central island before leaving through the chosen exit.
How can you recognise a roundabout?
A roundabout is normally identified by a circular-direction sign, a central island and entry roads controlled by signs, markings or local priority rules.
Which direction does traffic travel around a roundabout?
The direction depends on the country’s driving side. Traffic normally travels anticlockwise in right-hand-traffic countries and clockwise in left-hand-traffic countries.
Who has priority at a roundabout?
Priority differs between countries and roundabout designs. Entering traffic commonly gives way to traffic already circulating, but drivers must always follow the actual priority signs and signals.
Must you stop before entering a roundabout?
Not always. Stop when required by a stop sign, traffic light or approaching priority traffic. Otherwise, reduce speed and enter only when there is a safe gap.
Does a roundabout always have a give-way sign?
No. The sign arrangement depends on local law. Some circular intersections use ordinary priority rules or traffic lights instead.
How should you approach a roundabout?
Reduce speed, observe the signs and markings, choose the appropriate lane and check for pedestrians, cyclists and circulating traffic.
Which lane should you choose?
Follow the lane arrows and destination signs. As a general guide, use the lane appropriate for your exit, but exact lane-selection rules differ between countries and roundabout layouts.
May you use an inner lane?
Yes, where the road layout and local rules permit it. Before leaving, change lanes safely and give way to road users already travelling in the lane you wish to enter.
Do you need to signal when entering?
This depends on local law. Some countries require a signal for particular exits, while others require no signal when entering.
Do you need to signal when leaving?
Usually, yes. Signal in the direction of the exit early enough to inform other road users, but not so early that your intention becomes misleading.
Does signalling give you priority?
No. A direction indicator communicates your intention but does not permit you to force another road user to brake or change direction.
May you change lanes on a roundabout?
Only when the lane markings permit it and the manoeuvre can be completed safely. Check mirrors and blind spots, signal where required and give way to traffic already in the target lane.
What should you do if you miss your exit?
Continue around the roundabout and approach the exit again. Do not stop, reverse or cut suddenly across another lane.
May you drive over the central island?
Normally not. Some small roundabouts have a mountable central section intended only for vehicles that cannot otherwise negotiate the road safely.
Do cyclists have priority at a roundabout?
Priority depends on whether cyclists use the carriageway, a continuing bike path or a separate cycle crossing. Drivers and cyclists must follow the signs, markings and local priority rules.
What should drivers check before leaving?
Check mirrors and blind spots for cyclists, mopeds, motorcycles and vehicles beside you. Also check for pedestrians crossing the exit road.
Do pedestrians have priority at roundabout exits?
Pedestrian priority depends on crossings and local law. Drivers should approach exits slowly and be prepared to yield to pedestrians crossing or about to cross.
Does a roundabout have a special speed limit?
Not universally. The posted or general road limit applies, but drivers must travel slowly enough to negotiate the roundabout safely.
May you overtake on a roundabout?
Passing another vehicle may be permitted on a multilane roundabout, but drivers must remain within their lane and avoid unsafe lane changes. Local overtaking restrictions may apply.
May you stop or park on a roundabout?
Follow local signs and parking rules. Stopping or parking on the circulating roadway is commonly prohibited or unsafe because it obstructs traffic and reduces visibility.
Is every circular intersection a roundabout?
No. A circular junction may be governed by traffic lights, ordinary priority rules or another road design. Its legal status depends on its signs and local definition.
17. 道路幅員減少
道路幅員減少は、前方で車道または利用可能な通行幅が狭くなることを示します。工事、橋、障害物、車線減少、道路構造の変化などが原因です。
運転者は減速し、車線位置を調整し、対向車や隣接車線に注意する必要があります。どちら側が優先か、合流方法が指定されているかは標識や現地規則に従います。
What is a road narrowing?
A road narrowing is a section where the usable width of the road becomes smaller. Traffic may have less space to pass, merge or travel beside other road users.
How can you recognise a road narrowing?
It may be indicated by a triangular warning sign showing the road edges moving closer together. The symbol may show narrowing on both sides, the left side or the right side.
What can cause a road to narrow?
A road may narrow because of a bridge, tunnel, barrier, traffic-calming measure, roadworks, parked vehicles, landslide, damaged road edge or reduction in the number of lanes.
Does a narrowing sign impose a speed limit?
No. It normally warns of danger rather than setting a numerical speed limit. Drivers must still reduce speed when necessary to pass safely.
Does a narrowing sign determine who has priority?
Not by itself. Priority may be established by separate signs, signals or local rules. Without them, drivers should approach cautiously and cooperate.
Who has priority when the obstruction is on one side?
In many countries, the driver whose side is obstructed must give way to approaching traffic. The precise rule depends on local law and any priority signs displayed.
What if the road narrows equally from both sides?
Neither direction necessarily has automatic priority. Drivers should reduce speed, assess who can pass safely and avoid entering when doing so would block approaching traffic.
What do priority signs at a narrow section mean?
One sign may require you to give way to oncoming traffic, while the corresponding sign may indicate that you have priority. Drivers must still avoid entering when the passage is already occupied or blocked.
Does having priority mean you must continue?
No. Priority is not an obligation to proceed. Slow down or stop when another vehicle is already in the narrow section or when continuing would create danger.
What should you do when another vehicle is already in the narrowing?
Allow it enough room to leave the narrow section. Do not enter if the available width is insufficient for both vehicles to pass safely.
How should you approach a road narrowing?
Check mirrors, reduce speed smoothly and observe oncoming traffic, cyclists, pedestrians and vehicles beside you. Be prepared to stop or merge.
Must you use an indicator when the road narrows?
Use an indicator when you must change lanes or move laterally. Merely following a lane that bends with the road may not require a signal under local law.
What should you do when your lane ends?
Check the adjacent lane, signal and merge safely according to the local merging rules. Do not force another driver to brake or leave the road.
What is zipper merging?
Zipper merging means that vehicles from an ending or blocked lane merge alternately with vehicles in the continuing lane, usually immediately before the narrowing during congestion.
Should you merge early during heavy congestion?
Where zipper merging applies, continue using both lanes and merge alternately near the narrowing. In free-flowing traffic, change lanes safely when a suitable gap is available.
May you overtake near a road narrowing?
A narrowing sign does not always prohibit overtaking, but overtaking should be avoided when there is insufficient width, visibility or distance to complete the manoeuvre safely.
How should you pass cyclists at a narrowing?
Wait behind the cyclist when the required passing distance cannot be maintained. Do not squeeze past or force the cyclist towards a kerb, barrier or damaged road edge.
How should large vehicles use a narrow section?
Large vehicles may need additional width and may cross lane or centre markings where legally permitted. Other drivers should leave sufficient space and avoid passing alongside them in the narrowing.
May pedestrians be present at a road narrowing?
Yes. Pavements or verges may also become narrow or blocked. Drivers should expect pedestrians or wheelchair users to enter the carriageway to pass an obstruction.
May you stop or park in a road narrowing?
Only where it is permitted and enough width remains for traffic to pass safely. Never stop or park where the vehicle would create danger, obstruct visibility or prevent other vehicles from passing.
What should you do at a temporary roadworks narrowing?
Follow temporary signs, signals, barriers and instructions from authorised workers. Temporary traffic controls may replace the normal priority or lane arrangement.
What should you do in poor visibility?
Reduce speed further, increase the following distance and be prepared for a stopped vehicle beyond the narrowing. Use the required lights without dazzling approaching road users.
18. 横断歩道
横断歩道は、歩行者が道路を横断するために指定された場所です。路面標示、交通標識、信号、またはそれらの組み合わせで示されます。
運転者は適切に注意して接近し、現地法で必要な場合は歩行者へ道を譲ります。歩行者も接近車両を確認し、歩行者信号や交通整理員の指示に従う必要があります。
What is a pedestrian crossing?
A pedestrian crossing is a designated place for pedestrians to cross a road. It may be controlled by traffic lights or operate without signals.
How can you recognise a pedestrian crossing?
It may be indicated by white road markings, traffic signs, flashing lights, pedestrian signals or a raised crossing. Its appearance varies between countries.
Is a pedestrian crossing the same as a zebra crossing?
A zebra crossing is a type of pedestrian crossing marked by broad contrasting stripes or rectangles. Not every pedestrian crossing uses this design.
Do pedestrians always have priority?
Not universally. Priority depends on local law, traffic signals and whether the pedestrian is already crossing or clearly preparing to cross.
Must drivers stop for pedestrians waiting beside the crossing?
This depends on local law. In many countries, drivers must give way when a pedestrian is clearly intending or preparing to enter the crossing.
How should drivers approach a pedestrian crossing?
Reduce speed, observe both sides of the road and be prepared to stop. Pay particular attention to children, older people and persons with limited mobility.
May you enter a crossing when traffic is congested?
No. Do not enter when traffic ahead may force you to stop on the crossing and block pedestrians.
Where should you stop for a pedestrian?
Stop before the crossing or before the applicable stop line. Leave the crossing completely clear.
May you overtake near a pedestrian crossing?
Overtaking may be prohibited, particularly when another vehicle has stopped or slowed for the crossing. Even where no specific prohibition applies, overtaking is unsafe when pedestrians may be hidden from view.
May you stop or park on a pedestrian crossing?
Normally not. Stopping or parking on or immediately before a crossing can obstruct pedestrians and hide them from approaching drivers.
Does a pedestrian crossing impose a speed limit?
Not by itself. Drivers must respect the applicable speed limit and reduce their speed further when necessary to stop safely.
Do traffic lights change the priority rules?
Yes. Drivers and pedestrians must follow the signals applying to them. Drivers must still allow pedestrians who lawfully started crossing to finish safely.
May pedestrians cross when their signal is red?
No. Pedestrians must wait when the pedestrian signal prohibits them from entering the road.
What if the pedestrian signal changes while someone is crossing?
A pedestrian who entered lawfully should continue at a normal pace. Drivers must allow the crossing to be completed safely.
May cyclists ride across a pedestrian crossing?
This depends on local law. In many countries, a person riding a bicycle is treated as a driver and does not receive pedestrian priority. A cyclist walking beside the bicycle is normally treated as a pedestrian.
Is a pedestrian crossing also a cycle crossing?
Not automatically. A separate cycle crossing, cycle path or combined crossing may be indicated by additional markings or signs.
Must pedestrians use a nearby crossing?
Some countries require pedestrians to use a crossing when one is located within a specified distance. Other countries allow crossing elsewhere when it can be done safely.
May pedestrians remain standing on the crossing?
No. Pedestrians should cross without unnecessary delay and should not obstruct traffic by stopping or lingering on the road.
Does a raised pedestrian crossing change priority?
The raised surface itself does not necessarily determine priority. Drivers and pedestrians must follow the crossing markings, signs, signals and local rules.
What should drivers check when turning across a crossing?
Check for pedestrians approaching from both sides and give way where required. Turning drivers should not focus only on motor traffic.
What should pedestrians do before crossing?
Observe approaching traffic, make sure drivers have sufficient time to react and cross carefully. Priority does not remove the need to avoid stepping into the path of a vehicle that cannot stop safely.
19. 踏切
踏切は、道路または通路と鉄道線路が同じ高さで交差する場所で、level crossingやrailroad crossingとも呼ばれます。遮断機、警報灯、警報音、標識などで保護される場合があります。
道路利用者は慎重に接近し、列車が接近している場合、警報が作動している場合、出口側が塞がれている場合は進入してはいけません。速やかに横断し、線路上で停止、待機、立ち往生してはなりません。
What is a railway crossing?
A railway crossing is a place where a road or path crosses railway tracks at the same level.
What is another name for a railway crossing?
It may also be called a level crossing or, particularly in North America, a railroad crossing.
How can you recognise a railway crossing?
It may be indicated by warning signs, crossbuck signs, barriers, flashing lights, bells or road markings. The design differs between countries.
What is the difference between a crossing with and without barriers?
A protected crossing uses full or partial barriers to block road traffic when a train approaches. A crossing without barriers relies on signs, lights, bells or the road user’s own observation.
Must you always stop at a railway crossing?
Not necessarily. You must stop when required by lights, barriers, signs, an approaching train or an authorised person. At an unprotected crossing, slow down and proceed only after checking that no train is approaching.
What do flashing red lights mean?
Flashing red lights mean stop and do not enter the crossing. Remain stopped until the signal permits you to continue.
May you cross while a barrier is moving?
No. Do not enter while a barrier is lowering, rising or closed. Wait until the crossing is fully open and all prohibiting signals have stopped.
May you drive around a closed barrier?
No. Never drive, cycle or walk around or underneath a closed or moving barrier.
What does a warning bell mean?
A warning bell or audible signal normally means that the crossing is closing or that a train is approaching. Do not enter the crossing while it is sounding.
What does a flashing white light mean?
In some countries, a flashing white light indicates that the crossing equipment is operating and road users may pass when the route is clear. Its exact meaning depends on local law.
What should you do at a crossing without lights or barriers?
Reduce speed, look and listen carefully in both directions and cross only after making sure that no train or other rail vehicle is approaching.
May you cross immediately after a train has passed?
Not automatically. Another train may approach on a second track. Wait until all warning signals stop and the crossing is fully open.
What if traffic ahead is blocking the exit?
Do not enter the crossing unless there is enough room beyond the tracks for your entire vehicle. Never rely on traffic moving before a train arrives.
May you wait on the tracks?
No. Railway tracks must always remain clear. Do not stop because of congestion, traffic lights or another obstruction beyond the crossing.
May you overtake at a railway crossing?
Overtaking is often prohibited or restricted because another vehicle can obstruct the view of an approaching train or warning signal. Follow local signs and overtaking rules.
May you stop or park on a railway crossing?
No. Stopping or parking on the tracks creates an immediate and potentially fatal danger.
Do the crossing signals apply to pedestrians and cyclists?
Yes. Pedestrians and cyclists must obey barriers, lights, bells and authorised personnel in the same way as other road users.
Should cyclists ride across the tracks at an angle?
Where possible, cross the rails at an angle close to 90 degrees. Rails can trap a bicycle wheel, especially when they are wet or cross the road diagonally.
What should drivers of long vehicles check?
Make sure the entire vehicle and any trailer can clear the crossing without stopping. Consider the available space, road gradient, turning room and traffic beyond the tracks.
What should drivers of high vehicles check?
Observe all height restrictions and warning signs. Electrified railway lines may have overhead equipment that can be struck by an excessively high vehicle or load.
What should you do if the signals appear defective?
Treat the crossing with extreme caution. Do not assume that no train is approaching merely because the lights or barriers are not operating.
What should you do if your vehicle becomes stuck on the tracks?
Evacuate everyone immediately, move well away from the railway and contact the emergency services or railway operator. Do not remain in the vehicle or return for belongings.
Is a railway crossing the same as tram tracks in the road?
Not always. A railway crossing normally crosses tracks that are separate from the carriageway, while tram or street-running railway tracks may form part of the road itself.
20. 右左折禁止
右左折禁止は、交通標識で示された方向への右折、左折、またはUターンを禁止する規制です。交差点または指定道路区間で適用されます。
運転者は許可された経路を進み、車線矢印や指定方向標識に従います。この禁止はそれ自体で優先関係や速度を定めず、自転車、公共交通などへの例外は明示されている場合のみ適用されます。
What is a turn prohibition?
A turn prohibition prevents drivers from making a particular turn or change of direction indicated by a traffic sign.
How can you recognise a turn-prohibition sign?
It is commonly a circular sign with a red border showing a crossed or barred turning arrow. The arrow indicates the movement that is prohibited.
What does a no-left-turn sign mean?
It prohibits drivers from turning left at the location or intersection to which the sign applies.
What does a no-right-turn sign mean?
It prohibits drivers from turning right at the location or intersection to which the sign applies.
What does a no-U-turn sign mean?
It prohibits drivers from turning around to travel in the opposite direction.
Is a prohibited turn the same as a mandatory direction?
No. A prohibition sign identifies a movement that may not be made. A mandatory-direction sign identifies the direction or directions that must be followed.
Is a turn prohibition the same as a no-entry sign?
No. A turn prohibition prevents a particular approach from turning into a road. A no-entry sign prohibits vehicles from entering the road from the direction where it is displayed.
Is a turn prohibition the same as one-way traffic?
No. A one-way rule controls the permitted direction along a road. A turn prohibition controls a particular movement at or near an intersection.
When does a turn prohibition apply?
It may apply at the sign, at the next intersection or throughout a stated section. Drivers must follow the sign design and the rules of the country concerned.
Can a turn prohibition be announced in advance?
Yes. An advance sign or supplementary distance panel may warn drivers that the prohibited turn is farther ahead.
Can the sign apply to only one lane?
Yes. A sign positioned above or clearly associated with one lane may apply only to drivers using that lane.
Do lane arrows also restrict turning?
Yes. Drivers must choose the correct lane and follow one of the directions displayed by its legally binding arrows.
Does a green traffic light permit a prohibited turn?
No. A green light permits traffic to proceed, but drivers must still respect turn prohibitions, lane arrows and other regulatory signs.
Does a turn prohibition change priority?
No. Drivers making another permitted movement must still follow traffic lights, priority signs and the ordinary rules concerning pedestrians, cyclists and other vehicles.
Does a turn prohibition impose a speed limit?
No. The applicable general, zonal or posted speed limit remains in force.
Must you use an indicator for a permitted turn?
Yes, where local law requires it. Signal early enough to communicate your intention and stop signalling after completing the movement.
Does signalling make a prohibited turn legal?
No. An indicator communicates an intention but cannot authorise a movement prohibited by a traffic sign.
May cyclists be exempted?
Yes. A supplementary sign may allow cyclists or other specified road users to make a turn that remains prohibited for general traffic.
May buses or taxis be exempted?
Public transport, taxis or other authorised vehicles may be exempted where a supplementary sign or local rule expressly permits the movement.
Does a no-left-turn sign also prohibit a U-turn?
Not universally. Some countries treat these as separate prohibitions. Drivers must check whether a separate no-U-turn sign or general rule applies.
May you turn into a driveway before the prohibited intersection?
This depends on the exact legal scope of the sign. A sign applying specifically to the next intersection may not regulate an earlier property entrance, but another sign or road marking may still prohibit the movement.
May you reverse to avoid the turn prohibition?
No. Do not reverse through traffic or into an intersection to evade the sign. Continue along a permitted route and change direction later where it is legal and safe.
What should you do after entering the wrong lane?
Follow the movement permitted from that lane. Do not turn suddenly across another lane or ignore the sign; continue and choose another legal route.
Can a temporary turn prohibition be binding?
Yes. Properly placed temporary signs near roadworks, incidents or events must be obeyed.
Do instructions from an authorised officer override the sign?
Yes. Follow instructions from an authorised traffic officer even when they differ from the displayed turn prohibition.
21. 学校周辺
学校周辺は、多くの子どもが徒歩、自転車で通行し、道路を横断したり車両へ乗降したりする可能性が高い学校付近の道路または道路群です。警戒標識、ゾーン標識、路面表示、交通静穏化設備、点滅灯などで示されます。
特別な速度制限、駐車規制、進入規制が常時または登下校時間だけ適用されることがあります。運転者は減速し、子どもを注意深く確認し、停止できるよう備える必要があります。
What is a school area?
A school area is a road or group of roads near a school where drivers should expect large numbers of children, pedestrians, cyclists and stopping vehicles.
How can you recognise a school area?
It may be identified by school warning signs, speed-zone signs, flashing lights, road markings, coloured surfacing or traffic-calming measures. The signs differ between countries.
Does every road beside a school have special legal rules?
No. Special school-area rules normally apply only where signs, signals or local legislation establish them.
What is the speed limit in a school area?
There is no universal school-area speed limit. The applicable limit depends on the country, region, signs and whether a variable restriction is active.
Is the school-area speed limit always active?
Some limits apply permanently, while others apply only during displayed times or when flashing or variable signs are active. Drivers must observe the actual sign arrangement.
Must you drive below the displayed limit?
Yes, when necessary. The displayed speed is a maximum. Children, congestion, poor visibility or vehicles stopping near the school may require a much lower speed.
Why are children especially vulnerable in traffic?
Children may have difficulty judging speed and distance, may be hidden by parked vehicles and may enter the road unexpectedly.
How should you approach a school area?
Reduce speed early, increase your observation and be prepared for children crossing, cyclists changing direction, vehicle doors opening and cars stopping suddenly.
Do children automatically have priority everywhere?
No. Priority depends on crossings, traffic lights, authorised crossing supervisors and local rules. Drivers must nevertheless take exceptional care to avoid endangering children.
Must you obey a school crossing supervisor?
Yes. Drivers and other road users must follow lawful instructions given by an authorised person controlling traffic for children.
May children cross away from a pedestrian crossing?
This depends on local pedestrian rules. Drivers should remain prepared for children to cross unexpectedly, even where they are required to use a nearby crossing.
Does a school sign create pedestrian priority?
Not by itself. A school warning sign alerts drivers to children but does not normally create the legal effect of a pedestrian crossing.
Does a school area change intersection priority?
No. Traffic lights, priority signs and the ordinary intersection rules remain applicable unless another traffic arrangement provides otherwise.
May you overtake in a school area?
Overtaking may be restricted by signs or local law. Even where it is permitted, drivers should not overtake when children, crossings, limited visibility or stopped vehicles make the manoeuvre unsafe.
May you stop to drop off a child?
Only where stopping is permitted and can be completed safely. Do not stop on a crossing, pavement, bike path, bus stop or another prohibited or dangerous location.
May you park near a school entrance?
Follow the parking signs and markings. Do not block entrances, pavements, bike paths, crossings, visibility or access for buses and emergency vehicles.
Why is double parking dangerous near a school?
It blocks traffic and visibility and may force children to walk between moving vehicles or enter the road from behind an obstruction.
What should you watch for near school buses?
Expect children to enter or leave the vehicle and possibly cross the road. Reduce speed and follow any special warning lights, signs or local school-bus rules.
May cyclists ride through a school area?
Normally, yes. They must follow the applicable road, bike-path, speed and priority rules. Drivers should expect inexperienced young cyclists.
Is a school area the same as a school street?
No. A school area normally remains open to traffic under special caution or speed rules. A school street temporarily restricts or excludes motor traffic during specified periods.
Is a school area the same as a Zone 30?
Not universally. A school area may form part of a Zone 30, use another speed limit or have a variable restriction that applies only at particular times.
When do the school-area rules end?
They normally end at an end sign, at the end of the stated time period or when the variable signal is no longer active. The surrounding road rules then apply.
22. 動物横断
動物横断警戒は、野生動物、家畜、乗用動物が道路へ進入または横断する可能性がある場所を示します。動物は突然現れ、予測できない動きをし、暗闇や植生、悪天候では見えにくいことがあります。
運転者は減速し、道路両側を確認し、停止できるよう備える必要があります。この標識自体が動物に法的優先権を与えたり特定速度を定めたりするわけではありませんが、動物を驚かせたり危険にさらしたり衝突したりしないよう運転します。
What does an animals-crossing sign mean?
It warns that animals may enter or cross the road in the area ahead.
Which animals may the sign refer to?
Depending on the symbol and local conditions, it may refer to deer, cattle, horses, sheep, goats, wild boar or other animals.
How can you recognise an animals-crossing sign?
It is commonly a triangular warning sign displaying the silhouette of an animal. The species shown may indicate the type of animal most likely to be encountered.
Does the sign mean animals are always present?
No. It indicates an increased likelihood of animals crossing, not that animals will be present every time.
Does the sign impose a speed limit?
No. The normal posted or general speed limit remains applicable, but drivers must reduce speed when necessary to react safely.
Do animals have priority because of the sign?
No automatic priority is created by the warning sign. Drivers must nevertheless avoid danger and allow animals already on the road to pass safely.
How should you approach an animal-crossing area?
Reduce speed, increase your following distance and scan the road, verges, fields and vegetation for movement or reflected eyes.
When are wild animals most likely to appear?
Animal activity is often greater around dawn, dusk and darkness, although animals may cross at any time.
Why should you expect more than one animal?
Many animals travel in groups. When one animal crosses, others may follow immediately from the same direction.
Should you sound the horn?
Avoid unnecessary horn use or engine revving because it may frighten an animal and make its movement less predictable. Use a warning only when reasonably necessary to prevent danger.
Should you use full-beam headlights?
Use the appropriate lights without dazzling other road users. When an animal is visible, reduce speed and avoid relying on full beam to make it move away.
What should you do when an animal is on the road?
Slow down smoothly, stop when necessary and allow it enough time and space to leave. Avoid sudden acceleration or aggressive steering.
Should you swerve to avoid an animal?
Avoid an uncontrolled swerve that could cause a collision with another vehicle, tree, barrier, cyclist or pedestrian. Brake firmly while maintaining control and steer only when a safe escape path is clearly available.
How should you pass livestock?
Pass only when the animals and their handlers have sufficient space. Drive slowly, avoid noise and be prepared for an animal to change direction unexpectedly.
How should you pass a horse and rider?
Reduce speed, leave a large lateral distance and pass quietly. Avoid sounding the horn, accelerating sharply or passing when oncoming traffic prevents sufficient clearance.
Must you follow instructions from an animal handler?
Follow lawful instructions from an authorised person and cooperate with handlers controlling animals on or across the road.
May you overtake near an animal crossing?
The warning sign does not necessarily prohibit overtaking, but overtaking should be avoided when animals, limited visibility or approaching traffic make the manoeuvre unsafe.
What if an animal appears behind another vehicle?
Maintain enough following distance to see beyond the vehicle ahead. Be prepared for it to brake suddenly when an animal enters the road.
What should motorcyclists and cyclists do?
Reduce speed, keep both hands firmly in control and avoid sudden movements. Animals may react unexpectedly to quiet or fast-approaching two-wheeled vehicles.
What should you do after hitting an animal?
Stop safely, activate the hazard warning lights and check for injured people. Contact the emergency services or police when necessary and do not approach a wounded wild animal, which may defend itself.
Should you move an injured or dead wild animal?
Normally not. Keep a safe distance and allow the police, wildlife authorities or an animal-rescue service to handle it.
Can animals be present without a warning sign?
Yes. Drivers remain responsible for observing the road and adjusting their speed even where no animal warning sign is displayed.
23. 滑りやすい道路
滑りやすい道路はタイヤのグリップが低下し、操舵、制動、加速の効果が弱くなる道路です。雨、氷、雪、泥、油、砂利などで路面が滑りやすくなります。運転者は速度を落とし、車間距離を増やし、急な操舵、制動、加速を避ける必要があります。カーブ、橋、路面状態が突然変わる場所では特に注意します。
What makes a road slippery?
A road can become slippery because of rain, ice, snow, mud, oil, loose material or other substances that reduce tyre grip.
How should you drive on a slippery road?
Reduce speed, increase your following distance and use smooth steering, braking and acceleration. Sudden movements can cause the tyres to lose grip.
Why does braking distance increase on a slippery road?
Reduced tyre grip means the tyres cannot generate as much braking force, so the vehicle may need a longer distance to slow down or stop.
Can a road be slippery even when it looks dry?
Yes. Oil, dust, loose material or a thin layer of ice can reduce grip even when the road does not appear obviously wet or slippery.
Are bends more dangerous on slippery roads?
Yes. Turning requires tyre grip, so a slippery surface can make it easier for the vehicle to skid or leave its intended path, especially at higher speeds.
What should you do if your vehicle starts to skid?
Stay calm and avoid sudden braking or steering. Make smooth corrections and allow the tyres to regain grip. The correct response can depend on the vehicle and its safety systems.
24. カーブ
カーブは、道路が左または右へ方向を変える区間です。急なカーブ、予期しにくいカーブ、見通しの悪いカーブでは、対向車、停止車両、歩行者、その他の危険を確認できる距離が短くなります。
運転者はカーブに入る前に減速し、自分の車線内を保ち、滑らかに操舵、制動、加速します。警戒標識は最初のカーブ方向や連続カーブを示す場合があります。
What is a road curve?
A road curve is a section where the road changes direction to the left or right.
How can you recognise a dangerous curve?
It may be indicated by a triangular warning sign showing a curved line. The symbol normally indicates whether the first curve turns left or right.
What is a double curve?
A double curve consists of two curves in opposite directions. The warning sign normally shows the direction of the first curve.
Can a sign warn of more than two curves?
Yes. A double-curve symbol may also warn of a longer sequence of successive curves. A supplementary panel may indicate the length of the winding section.
Does a curve-warning sign impose a speed limit?
No. It normally warns of danger rather than setting a numerical limit. Drivers must still reduce speed when the permitted maximum would be unsafe.
When should you reduce speed for a curve?
Reduce speed before entering the curve, while the vehicle is travelling straight and has maximum stability.
Should you brake heavily while cornering?
No. Harsh braking in a curve can reduce stability and grip. Complete most braking beforehand and use smooth adjustments where necessary.
Should you accelerate through a curve?
Maintain a controlled speed through the curve. Accelerate smoothly only when the exit becomes visible and the vehicle is stable.
Where should you look while driving through a curve?
Look towards the path you intend to follow and the visible exit of the curve. Continue checking the road surface, lane position and nearby traffic.
Must you remain in your lane?
Yes. Do not cross the centre line or cut across another lane, even when this would make the curve appear easier to negotiate.
Why is visibility limited in a curve?
Buildings, vegetation, slopes, barriers and the road alignment may hide oncoming traffic, cyclists, pedestrians, stopped vehicles or debris.
How fast should you drive through a curve?
Choose a speed that allows you to remain in your lane and stop within the distance you can see to be clear. The safe speed may be far below the legal maximum.
What is an advisory speed for a curve?
An advisory speed is a recommended safe speed for negotiating the curve under suitable conditions. It is not necessarily the legal maximum speed.
How do rain, snow or ice affect a curve?
They reduce tyre grip and increase the risk of skidding. Reduce speed earlier, use smooth controls and leave additional distance from other vehicles.
What should you do if gravel or debris is present?
Avoid sudden braking or steering. Reduce speed smoothly and follow a clear path without entering another traffic lane.
May you overtake in a curve?
Do not overtake when visibility is insufficient to see approaching traffic and complete the manoeuvre safely. Local law, signs and continuous road markings may also prohibit overtaking.
May you stop or park in a curve?
Only where it is permitted and the vehicle remains clearly visible. Stopping or parking in a poorly visible curve may create a serious hazard and is often prohibited.
Should you follow another vehicle closely through a curve?
No. Leave enough distance to react if the vehicle ahead brakes for a hidden obstruction or a sharper part of the curve.
Why should motorcyclists take extra care?
Motorcycles require grip for both cornering and braking. Riders should reduce speed before the curve, choose a stable line and avoid painted markings, gravel and slippery surfaces.
How can a curve affect a trailer or caravan?
A trailer may sway, track closer to the inside of the curve or become unstable when speed and steering inputs are excessive. Enter slowly and steer smoothly.
Why do large vehicles need more space?
Buses and trucks may move closer to lane boundaries because of their length and width. Other drivers should avoid travelling beside them through a tight curve.
What should you do if an oncoming vehicle crosses the centre line?
Reduce speed, move safely towards your side of the road and avoid a sudden manoeuvre that could cause another collision. Sound a warning only when reasonably necessary.
Does the absence of a warning sign mean every curve is safe at the speed limit?
No. Drivers must assess every curve and adapt their speed even when no warning sign is displayed.
25. シェブロン標識
シェブロンは、道路の急な方向変化を示すV字形または矢印形の道路表示板です。通常、カーブ外側に設置され、先端が道路の進行方向を示します。
暗闇や悪天候でもカーブの位置と方向を分かりやすくします。通常、速度制限や優先関係そのものを定めるものではないため、運転者はカーブ前で減速し、他の標識や路面表示にも従う必要があります。
What is a road chevron?
A road chevron is a V-shaped or arrow-shaped marker used to guide drivers through a curve or another sharp change in road direction.
How can you recognise a chevron?
It is normally displayed on a rectangular board using strongly contrasting colours. Several chevrons may be placed in sequence around a curve.
Which direction does a chevron indicate?
The point of the chevron indicates the direction in which the road continues. A chevron pointing left guides traffic through a left curve, while one pointing right guides traffic through a right curve.
Where are chevrons normally placed?
They are generally placed along the outside of a curve, facing approaching traffic so that drivers can clearly see the road alignment.
What is the purpose of a series of chevrons?
A series of chevrons visually traces the curve and helps drivers judge its direction, length and changing alignment.
Is a chevron the same as a curve-warning sign?
No. A curve-warning sign normally warns drivers before the curve. Chevron boards are usually positioned within or around the curve to guide drivers through it.
Does a chevron impose a speed limit?
No. It guides drivers through the change in direction but does not normally introduce a numerical speed limit.
Does a chevron show a recommended speed?
Not by itself. A separate advisory-speed or speed-limit sign may indicate an appropriate or legally required speed.
Does a chevron determine priority?
No. Traffic lights, priority signs and the ordinary priority rules remain applicable.
Does a chevron mean the curve is dangerous?
It normally indicates that the curve requires additional visual guidance. Drivers should expect a noticeable or potentially sharp change in direction.
Does the number of chevrons show how sharp the curve is?
Not directly. The number and spacing depend on the length, radius and design of the curve and on the road authority’s signing standards.
Does a larger chevron mean a sharper curve?
Not necessarily. Larger boards may be used where approach speeds are higher or where greater visibility is needed.
How should you approach chevrons?
Reduce speed before the curve, observe the direction of the boards and remain within your traffic lane.
Should you brake heavily after reaching the chevrons?
No. Complete most braking before entering the curve and use smooth steering, braking and acceleration while following it.
May you drive towards the chevron boards?
No. The boards normally mark the outside edge of the curve. Follow the road around them rather than steering towards them.
May you cut across the centre line to straighten the curve?
No. Remain within your lane and do not enter the path of oncoming traffic.
May you overtake beside chevrons?
The chevrons do not automatically prohibit overtaking, but overtaking is unsafe when the curve restricts visibility or available road width.
Why are chevrons reflective?
Reflective material makes the boards easier to see in darkness and poor weather when illuminated by vehicle headlights.
Can chevrons be illuminated?
Yes. Some high-risk curves use illuminated or flashing chevrons to make the change in direction more conspicuous.
Can chevrons have different colours?
Yes. Their colours and design vary between countries, but contrasting colours are used to make the direction clearly visible.
What should motorcyclists consider?
Reduce speed before the curve, choose a stable path and look through the turn. Do not focus exclusively on the chevrons or allow the motorcycle to cross the centre line while leaning.
Does the absence of chevrons mean a curve is safe at the speed limit?
No. Drivers must assess every curve and select a safe speed whether or not chevron boards are installed.
