1. 南アフリカ
南アフリカはアフリカ南端に位置し、主要都市をハイベルト、半乾燥のカルー、沿岸地域、複数の山脈を通る長距離路線が結びます。交通は左側通行で、通常は右側から追い越します。国道は複数車線フリーウェイから長い対面通行区間まであり、疲労、野生動物・家畜、豪雨、霧、道路状態の変化が重大な危険となります。別の標識や車種別制限がなければ、一般的な速度枠組みは都市部60 km/h、都市部外100 km/h、フリーウェイ120 km/hです。
全国共通ヴィネットではなく路線別有料道路を採用し、複数の国道路線に従来型料金所があり、多くの施設でSANRAL電子タグも利用できます。ハウテン州の旧オープンロードe-toll制度は2024年に終了しました。オートバイは常時ヘッドライト点灯が必要ですが、普通乗用車には一般的な昼間点灯義務はありません。道路標識は南アフリカの全国制度を使用し、標準記号を多用します。文字情報では英語が広く使われ、地域や道路管理者により他の公用語も使われます。
南アフリカでは道路のどちら側を走りますか?
左側を走ります。通常の複数車線・対面通行道路では左側を保ち、安全・合法な場合は一般に右側から追い越します。
南アフリカではどの緊急通報番号を使えますか?

南アフリカのtraffic circleでは誰が優先ですか?
交通島の周囲を循環する交差点へ進入する運転者は、交通整理員・標識で別の指示がない限り、交差点内を右から接近する交通へ道を譲ります。「常に環状路内が優先」とだけ単純化してはいけません。
南アフリカのmini-circleでは誰が優先ですか?
標識のあるmini-circleでは譲れ線・標識に従います。South Africa K53では譲れ線を最初に横切る交通に通行権があるとされています。
南アフリカのfour-way stopではどうしますか?
すべての運転者が停止します。実務上の一般則では最初に停止した車両が最初に進み、同時到着の場合は適用される優先規則に従い、安全な場合だけ進みます。
南アフリカの横断歩道では歩行者へ道を譲る必要がありますか?
はい。指定横断歩道を横断する歩行者へ道を譲り、必要に応じて減速・停止します。横断歩道で停止した車両を追い越してはいけません。
観光客は外国の運転免許証で南アフリカを運転できますか?
はい。外国免許が有効で、南アフリカの承認要件を満たす場合に利用できます。公式案内では写真・署名など必要な本人識別情報を含む対象外国免許を認めています。
南アフリカでは観光客に国際運転免許証が必要ですか?
対象外国免許がそのまま認められる場合、IDPは一律必須ではありません。南アフリカの外交案内では英語表記の免許は訪問者に有効で、他言語の場合は国際運転免許証または適切な翻訳書類を取得すべきとしています。
南アフリカでは自動車保険は義務ですか?
道路事故による身体傷害・死亡を補償する法定Road Accident Fund(RAF)があります。これは通常の民間第三者・総合自動車保険とは異なり、物損などのため民間保険へ別途加入できます。
南アフリカの乗用車は警告三角表示板を携行する必要がありますか?
対象自動車は少なくとも認可済み緊急警告三角表示板1枚を搭載します。車種・旧型車に例外があります。故障時に必要な場合は、停止車両の十分後方へ置いて接近交通へ警告します。
南アフリカの自家用車は毎年roadworthy testが必要ですか?
一般に3500 kg未満の自家用車は年数が1年増えただけで毎年Certificate of Roadworthinessを受ける必要はありません。所有者変更時に検査が必要です。公共交通・一部大型車は毎年、バスは通常6か月ごとに検査します。
外国登録車は南アフリカ入国時に申告が必要ですか?
はい。2026年6月1日以降、外国登録車で南アフリカへ入出国する旅行者は税関手続の一部としてSARS Traveller Management Systemで車両を申告します。
南アフリカでレーダー探知機や速度カメラ妨害機は合法ですか?
いいえ。National Road Traffic Regulationsは速度監視・測定機器を妨害または検知する装置を禁止し、自動車で移動中にそのような装置を所持することも禁止します。
南アフリカのfreewayを歩行者や自転車は利用できますか?
一般にできません。National Road Traffic Regulationsは、法律で特に認められた状況を除き、歩行者と自転車、各種動物、不適切・低速車両をfreewayから制限します。
南アフリカでは交通事故を届け出る必要がありますか?
はい。届け出が必要な事故で現場に警察・交通官がいない場合、運転者は警察署または権限ある係員へ24時間以内に届け出ます。SAPSは事故届を本人が直接行う必要があるとしています。
南アフリカの道路標識ではどの言語が使われますか?
記号、色、形を多用する全国標準道路標識制度を使用します。文字情報では英語が広く使われ、地域・道路管理者により地名や補助文に他の公用語も使われます。
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. 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.
4. 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.
5. 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.
6. 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.
7. 行き止まり
行き止まりは、先で他の道路へ通り抜けられない道路です。車両通行はそこで終了し、運転者は戻る、方向転換する、または指定場所で駐車する必要があります。
道路が自動車には行き止まりでも、歩行者や自転車には通り抜け可能な場合があります。その場合、標識に補助記号が付くことがあります。
What is a dead-end road?
A dead-end road is a road that provides no through route for some or all vehicles. Traffic entering it normally has to return by the same route.
How can you recognise a dead end?
A dead end may be indicated by a blue rectangular sign showing a road blocked at one end. The exact colour, design and symbol vary between countries.
Does a dead-end sign prohibit entry?
Normally not. It generally provides information rather than prohibiting access. Drivers may enter to reach a destination unless another sign restricts entry.
Is a dead-end sign the same as a no-entry sign?
No. A dead-end sign warns that the road does not continue as a through route. A no-entry sign prohibits drivers from entering in the indicated direction.
Does a dead-end road always physically end?
No. It may end at a wall, gate, turning area or private property, or it may continue as a narrower path that motor vehicles cannot use.
Can pedestrians continue through a dead end?
Sometimes. A separate symbol, sign or visible path may indicate that pedestrians can continue beyond the point where motor traffic ends.
Can cyclists continue through a dead end?
Sometimes. A sign may indicate a through route for cyclists, but cyclists must still follow any access, direction and path-use rules that apply.
Does a dead-end sign change the speed limit?
No. The normal road, zonal or posted speed limit remains applicable. Drivers should nevertheless reduce speed when space, visibility or nearby pedestrians require it.
Does a dead-end road have different priority rules?
No. Traffic lights, priority signs and the ordinary intersection rules continue to apply.
Does traffic leaving a dead-end road have to give way?
Not solely because the road is a dead end. Priority depends on the signs, road surface, road category and local priority rules.
May you make a U-turn in a dead-end road?
A driver may turn around where the manoeuvre is legal, safe and does not obstruct other road users. Local signs or road markings may prohibit it.
May you reverse in a dead-end road?
Reverse only when necessary and when the route is clear. Give way to all other road users and avoid reversing for a long distance where a safer turning place is available.
Who has priority while a vehicle is turning around?
A driver performing a turning or reversing manoeuvre must normally give way to other road users.
May you park in a dead-end road?
The dead-end sign itself does not normally prohibit parking. Drivers must follow the ordinary parking rules and must not block entrances, pedestrian routes, emergency access or turning areas.
May you park in the turning area?
Only where parking is permitted and sufficient room remains for other vehicles to turn. Blocking the turning area can force vehicles to reverse for an unsafe distance.
Why should large vehicles avoid some dead-end roads?
Trucks, buses and vehicles towing trailers may not have enough space to turn around. Drivers should check the route and any length, width, weight or access restrictions before entering.
Can emergency vehicles enter a dead-end road?
Yes. Emergency and service vehicles may need access to properties within it. Other vehicles should not block the road or its turning space.
What should you do after entering a dead end by mistake?
Continue cautiously to a suitable turning place. Turn around or reverse only after checking carefully for pedestrians, cyclists, vehicles and other obstacles.
Does the absence of a dead-end sign guarantee a through route?
No. Temporary closures, private access, gates, roadworks or outdated navigation information may still prevent passage. Drivers must observe the actual road and signs.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
16. 逆走
逆走は、法律で定められた交通方向に反して走行することです。一方通行道路、分離道路、高速道路の入口・出口、その他一方向専用区間で発生することがあります。
逆走は正面衝突の極めて高い危険を生みます。方向標識、進入禁止標識、車線矢印、路面表示に従わなければなりません。誤って逆方向へ進入した場合は減速し、他車へ警告し、可能な限り安全な場所で停止して緊急サービスへ連絡します。
What is wrong-way driving?
Wrong-way driving means travelling against the legally permitted direction of traffic.
Where can wrong-way driving occur?
It can occur on one-way streets, divided roads, motorways, slip roads, tunnels, car parks and temporary traffic arrangements.
Why is wrong-way driving especially dangerous?
Other drivers do not expect approaching traffic in their lane, and the combined speeds can make a head-on collision extremely severe.
How can you recognise a prohibited direction?
Look for no-entry signs, one-way signs, mandatory-direction signs, lane arrows and road markings. Motorway exits may also have repeated signs or warning systems facing the wrong direction.
Is wrong-way driving the same as entering a no-entry road?
Entering past a no-entry sign can cause wrong-way driving, but the term also covers turning around on a divided road or using the wrong carriageway without passing such a sign.
Is driving against a one-way street always prohibited?
Normally, yes. However, signs may expressly permit certain road users, such as cyclists or public transport, to travel in the opposite direction.
Is authorised contraflow traffic wrong-way driving?
No. A cyclist, bus or other road user travelling in an expressly authorised contraflow lane or direction is using the road legally.
Can roadworks temporarily change the normal direction?
Yes. Temporary signs, barriers, lane signals and markings may redirect traffic onto another lane or carriageway. Follow the temporary arrangement rather than the usual road layout.
What should you do when you see a wrong-way driver?
Reduce speed immediately, keep as far as safely possible towards the outer edge of your carriageway and avoid sudden lane changes. Warn the police or emergency services as soon as this can be done safely.
Should you attempt to stop the wrong-way driver?
No. Do not block, chase or turn after the vehicle. Protect yourself and allow trained emergency services to intervene.
Should you flash your headlights?
A brief warning may help the driver recognise the error, but avoid prolonged or aggressive signalling that could cause panic or an unpredictable manoeuvre.
Should you sound the horn?
Use the horn only when reasonably necessary to warn of immediate danger. Your first priority is to reduce speed and create as much safe space as possible.
Should you stop in a live traffic lane?
Normally not. Sudden stopping may cause a rear-end collision. Slow down and move towards a safe shoulder, refuge or other protected location where possible.
What should you do after receiving a wrong-way-driver warning?
Reduce speed, stop overtaking, increase your following distance and remain in the lane or position recommended by the local authorities or warning system.
Should you continue using the overtaking lane?
Avoid unnecessary use of lanes nearest opposing or central traffic when a wrong-way driver has been reported. Follow local emergency guidance and electronic signs.
What should you do if you are driving in the wrong direction?
Slow down immediately, activate the hazard warning lights and use dipped headlights where required. Move to the safest available edge or shoulder and stop.
Should you accelerate to reach the next exit?
No. Increasing speed greatly increases the collision risk. Stop safely and wait for instructions from the police.
Should you make a U-turn across traffic?
No. Do not turn across live lanes, cross a central reservation or attempt to correct the mistake through another dangerous manoeuvre.
Should you reverse back to the entrance?
No. Reversing against traffic or along a motorway slip road creates additional danger. Stop safely and contact the emergency services.
Should you leave the vehicle after stopping?
This depends on the location and immediate danger. Remain protected from moving traffic and follow instructions from the emergency services. Do not stand in a live lane.
How should you contact the emergency services?
Stop safely before using a handheld phone. A passenger may call while the vehicle is moving when local law permits and this can be done without distracting the driver.
What information should you report?
Report the road name or number, direction, nearby exit or landmark, vehicle description and the wrong-way driver’s approximate location and direction.
What commonly causes wrong-way driving?
Possible causes include confusion at junctions, poor visibility, unfamiliar roads, impairment, navigation errors, turning around illegally or deliberately ignoring traffic signs.
How can drivers prevent entering the wrong direction?
Slow down at unfamiliar junctions, read signs before turning, verify the road layout and do not rely exclusively on navigation instructions.
Does a navigation system override traffic signs?
No. Traffic signs, signals, markings and instructions from authorised persons always take precedence over navigation guidance.
17. 信号機
信号機は、色灯、矢印、記号によって道路利用者が進行できる時、停止準備をする時、停止し続ける時を規制します。進行方向、車線、歩行者、自転車、公共交通ごとに別の信号がある場合があります。
青信号でも、進路が空いており、その動きが法的に許可される場合にのみ進めます。優先規則、右左折制限、車線表示、交通整理員の指示にも従う必要があります。
What are traffic lights?
Traffic lights are signals that use coloured lights, arrows or road-user symbols to regulate traffic movements.
What does a red traffic light mean?
A red light requires road users to stop before the stop line or signal and remain stopped until movement is permitted.
What does a steady amber light mean?
A steady amber light normally requires drivers to stop unless they are already too close to stop safely. It warns that the signal is changing to red.
What does a green traffic light mean?
A green light permits road users to pass the signal, but only when the route is clear and the intended movement is otherwise legal.
Does green mean that you have priority over everyone?
No. You may still have to give way to pedestrians, cyclists, oncoming traffic or other road users when turning or following a conditional arrow.
May you enter a blocked intersection on green?
No. Do not enter when congestion is likely to leave you stopped inside the intersection and obstructing crossing traffic.
Where should you stop at a red light?
Stop before the stop line. When no stop line is provided, stop before the traffic light or at another legally prescribed position.
May you cross the stop line and then stop?
No. The required stop must normally be completed before the stop line. Do not stop on a pedestrian or cycle crossing.
What if the light changes to amber while you are approaching?
Stop when this can be done safely. Continue only when you are already too close to stop without creating danger.
Should you accelerate to pass an amber light?
No. Do not accelerate to avoid stopping. Maintain control and stop unless doing so safely is no longer possible.
What do arrow-shaped traffic lights mean?
They have the same general meaning as circular lights, but the prohibition or permission applies only to the direction shown by the arrow.
What does a green arrow displayed with a red light mean?
It may permit travel in the indicated direction while other movements remain prohibited. Drivers may still have to give way to conflicting traffic and pedestrians.
Does a green arrow override a no-turn sign?
Not universally. Drivers must follow the complete local sign arrangement. A traffic signal does not necessarily cancel a separate regulatory prohibition.
May you turn right on red?
Only where local law or a specific sign or signal expressly permits it. There is no universal right to turn on red.
What does a flashing amber light mean?
It warns of a potential hazard and normally allows cautious passage. The ordinary priority arrangement remains applicable.
What should you do when the normal lights are flashing amber?
Reduce speed, observe the intersection carefully and follow the applicable priority signs or default priority rules.
What does a flashing red light mean?
Its meaning depends on local law. At railway crossings and some movable bridges, flashing red lights normally require road users to stop.
What do lane-control signals mean?
A red cross normally closes the lane, a green downward arrow opens it and an amber diagonal arrow instructs drivers to leave the lane in the indicated direction.
May you continue beneath a red lane-control cross?
No. Move out of the lane safely before reaching the red cross unless an authorised person or emergency rule directs otherwise.
What does an amber diagonal lane arrow mean?
It warns that the lane is closing or unavailable ahead. Drivers must move into the adjacent lane indicated by the arrow when safe.
Can separate lights apply to cyclists?
Yes. A signal displaying a bicycle symbol applies to the road users legally covered by that signal rather than to general motor traffic.
Can separate lights apply to pedestrians?
Yes. Pedestrian lights normally use red and green human figures to indicate whether pedestrians may begin crossing.
What does a flashing green pedestrian light mean?
It normally warns that the crossing period is about to end. Pedestrians who have not started should wait for the next green signal.
What if the pedestrian signal changes while someone is crossing?
A person who entered lawfully should continue without unnecessary delay. Turning drivers must allow the crossing to be completed safely.
Can buses and trams have separate traffic lights?
Yes. Public-transport signals may use bars, circles, triangles or other symbols that apply only to authorised service vehicles.
Do functioning traffic lights override priority signs?
They commonly replace the priority arrangement at that location. Priority signs may apply again when the normal signals are inactive or flashing.
Do instructions from a police officer override traffic lights?
Yes. Instructions from an authorised traffic controller normally take precedence over lights, signs, markings and ordinary rules.
What should you do when the lights are not working?
Reduce speed and follow the priority signs, temporary signals, authorised personnel or default priority rules that apply.
May you clear an intersection after the light turns red?
Yes, when you entered lawfully and must leave the intersection. Complete the movement cautiously without endangering other road users.
Does a green light impose a minimum speed?
No. Drivers may proceed but must continue at a safe and legal speed.
May you use a handheld phone while waiting at red?
This depends on local law. In many countries, a driver temporarily stopped in traffic is still considered to be driving and may not use a handheld device.
18. 信号機あり警戒
信号機あり警戒は、前方に信号機があることを運転者へ知らせる警戒標識です。信号が予想しにくい、遠くから見えにくい、停止準備に時間が必要な道路などで使われます。
接近時は必要に応じて減速し、前方信号を確認し、信号変化や交差点の待ち交通に備えて停止できるようにする必要があります。
What does a traffic lights warning mean?
A traffic lights warning alerts drivers that traffic signals are located ahead.
Why is a traffic lights warning sign used?
It may be used where traffic lights are unexpected, difficult to see sufficiently early or located on a road where advance warning improves safety.
How should you react to a traffic lights warning?
Remain alert, reduce speed when necessary and be prepared to stop at the traffic lights or behind waiting traffic.
19. 道路反射鏡
道路反射鏡は、見通しの悪い交差点、出入口、カーブなどに設置される凸面鏡です。曲面により通常の平面鏡より広い範囲の接近交通を確認できます。
道路反射鏡はあくまで視認補助です。距離、速度、方向が歪んで見え、暗闇、天候、汚れ、破損の影響も受けます。運転者は直接道路も確認し、優先規則に従い、安全な場合にのみ進行します。
What is a traffic mirror?
A traffic mirror is a convex roadside mirror that helps road users see around an obstruction or into a road with limited visibility.
Where are traffic mirrors commonly installed?
They may be placed near intersections, narrow roads, bends, car-park exits, private driveways, tunnels or other locations where buildings, vegetation or road geometry obstruct the view.
Why is the mirror curved?
A convex surface provides a wider field of view than a flat mirror, allowing more of the approaching road to be seen.
Does a traffic mirror show an exact image?
No. The reflected image is distorted, and objects normally appear smaller and farther away than they really are.
Can you accurately judge speed in a traffic mirror?
Not reliably. The curved image makes it difficult to estimate how fast another road user is approaching.
Can you accurately judge distance in the mirror?
No. Distance can appear greater than it really is, so an approaching vehicle may reach the intersection sooner than expected.
Can the mirror create a blind area?
Yes. Its position and viewing angle may leave parts of the road outside the reflected image. Small cyclists, motorcycles or pedestrians may also be difficult to notice.
Does a traffic mirror give you priority?
No. It does not change priority. Drivers must continue to follow stop signs, give-way signs, traffic lights and the ordinary priority rules.
Does seeing an empty mirror mean the road is clear?
No. Another road user may be outside the reflected area, hidden by glare or too small to notice. Always check the road directly before proceeding.
Must you still stop at a stop sign?
Yes. The mirror does not replace the mandatory complete stop. Stop at the prescribed position, then use direct observation and the mirror as additional information.
Must you still give way?
Yes. You may proceed only when traffic with priority can continue without being forced to brake, stop or change direction.
How should you use a traffic mirror?
Approach slowly, stop when required and scan the mirror for movement. Then look directly in both directions and continue only after confirming that the road is clear.
Should you look only at the mirror?
No. Alternate between the mirror and direct observation. The mirror should supplement rather than replace normal checks.
Can rain affect a traffic mirror?
Yes. Rain, water droplets and spray may blur or partially obscure the reflected image.
Can frost or condensation affect it?
Yes. Dew, condensation, frost, ice or snow may make the mirror difficult or impossible to use.
Can sunlight cause problems?
Yes. Sunlight may create glare or reflections that hide approaching road users.
Can headlights be misleading at night?
Yes. Reflected headlights may make it difficult to determine the exact direction, distance or speed of an approaching vehicle.
Can the mirror move out of position?
Yes. Wind, impacts, vandalism, vibration or temperature changes may alter its orientation and make the reflected view inaccurate.
What if the mirror is dirty or damaged?
Do not rely on it. Proceed with additional caution and report the defect to the responsible road authority or property owner.
Does a traffic mirror impose a speed limit?
No. The applicable road or posted speed limit remains in force, but restricted visibility normally requires a lower approach speed.
Does it require drivers to sound the horn?
No. Use the horn only where local law permits it and a warning is reasonably necessary to prevent danger.
Can pedestrians and cyclists use the mirror?
Yes. It may help them observe approaching traffic, but they must also look directly and follow the applicable crossing and priority rules.
Can a private individual install a traffic mirror?
A mirror may generally be installed on private property with the owner’s permission, subject to local rules. Installing one on, above or beside a public road normally requires permission from the road authority.
Should a mirror replace better road design?
No. Removing vegetation, relocating parking, improving the intersection layout or changing traffic circulation may provide a safer and more reliable solution.
20. 駐車
駐車とは、交通状況や直ちに必要な事情による短時間停止ではなく、一定時間車両を静止させておくことです。多くの国では、乗客の乗降や荷物の積み下ろしのための短時間停止と駐車を区別しますが、法的定義は異なります。
駐車は交通標識、路面表示、駐車ゾーン、地域規則により許可、制限、予約、時間制、禁止となります。危険や不必要な妨害を生じないようにし、支払、許可証、車種、最長時間などの条件に従います。
What is the difference between parking and stopping?
Parking generally means leaving a vehicle stationary for longer than a brief stop required for passengers, loading or unloading. A vehicle stopped because of traffic lights, congestion, an emergency or another traffic condition is normally not considered parked. The precise legal definitions vary between countries.
How can you tell where parking is allowed?
Look for parking signs, prohibition signs, road markings and parking-zone signs. Local rules may also permit parking along certain roads even when individual parking spaces are not marked.
Can you park anywhere if there is no sign prohibiting parking?
No. General traffic rules can prohibit parking even when no specific prohibition sign is present. Common examples include locations where a parked vehicle would obstruct visibility, crossings, intersections, cycle facilities or the movement of other traffic.
Can you park on a pavement or sidewalk?
Parking on a pavement or sidewalk is prohibited or restricted in many countries unless signs or markings specifically allow it. Vehicles must not force pedestrians into the roadway or block an accessible pedestrian route.
Can you park near a pedestrian crossing?
Parking on or close to a pedestrian crossing is generally restricted because a vehicle can hide pedestrians from approaching drivers. The required clearance distance varies between countries.
Can you park close to an intersection?
Many countries prohibit parking within a specified distance of an intersection because parked vehicles can reduce visibility and obstruct turning traffic. Follow the local distance requirements and any signs or markings.
What does a parking sign mean?
A parking sign identifies a place or area where parking is permitted or regulated. Additional signs or panels may specify time limits, payment requirements, vehicle categories, permits or particular parking arrangements.
How does paid parking work?
Where parking is subject to payment, drivers must follow the instructions displayed locally. Payment may be made through a parking meter, ticket machine, mobile application or another authorised system. The permitted duration and charging periods vary by location.
Who may use an accessible parking space?
Spaces marked for people with disabilities are reserved for vehicles displaying or registered with the required disability parking permit. Eligibility, permit display requirements and parking privileges depend on national and local law.
Can you leave a vehicle parked for an unlimited time?
Not necessarily. Local rules may impose a maximum parking duration, even where parking is otherwise permitted. Different limits may apply to abandoned, commercial, heavy or recreational vehicles.
21. 後退
後退は車両を後ろ向きに動かすことです。駐車、狭い場所から出るとき、前進では位置調整できない場合などに使われます。
後退前にミラーと死角を確認し、車両周囲をよく見て後方が空いていることを確かめます。後方視界は限られるため、ゆっくり、必要な距離だけ後退します。
What should you check before reversing?
Check behind and around the vehicle for pedestrians, cyclists, other vehicles and obstacles. Use mirrors and cameras where available, but also look directly because monitoring systems can have blind spots.
Who has priority when a vehicle is reversing?
In many countries, reversing is treated as a manoeuvre and the reversing driver must give way to other road users. The exact legal requirements depend on national traffic rules.
Should you reverse for a long distance?
No. Reversing should normally be limited to the distance necessary to complete the manoeuvre safely. Driving forward generally provides better visibility and vehicle control.
22. 観光地
観光地は、文化、歴史、レクリエーション、自然、娯楽などを目的に訪問者が向かう場所です。記念碑、城、博物館、景勝地、遊園地などが含まれます。
目的地への案内には観光標識や方面案内標識が使われます。色、記号、表示される施設の種類は国によって異なります。
What is a tourist attraction?
A tourist attraction is a place that visitors travel to because of its cultural, historical, natural, recreational or entertainment value.
What are examples of tourist attractions?
Examples include monuments, castles, museums, scenic locations, cultural sites, amusement parks and recreational destinations.
Can tourist attractions be indicated by road signs?
Yes. Many countries use tourist or direction signs to guide travellers toward important attractions and places of interest.
23. 一般危険
一般危険警戒標識は、より具体的な警戒標識で表せない前方の危険を知らせます。補助標識、文字、記号などで具体的な危険内容が示される場合があります。
運転者は注意を高め、前方を確認し、危険と周囲の状況に合わせて速度を調整します。標識の形や危険の示し方は国によって異なるため、現地の交通標識と規則に従います。
What does a general danger warning sign mean?
A general danger warning sign indicates that there is a hazard ahead that is not represented by a more specific warning sign in the local traffic-sign system.
What kind of danger can the sign indicate?
It can be used for unusual or uncommon hazards for which no dedicated warning symbol exists. The nature of the danger may be explained by an additional panel, symbol or message.
How can you know what the danger is?
Look for a supplementary panel, text or symbol accompanying the warning sign. It may describe the hazard or provide information needed to understand the warning.
What should you do when you see a general danger warning sign?
Increase your attention, observe the road and surroundings carefully and adapt your speed where necessary so that you can respond safely to the hazard.
Does the sign impose a specific speed limit?
Not normally. A warning sign alerts road users to danger rather than establishing a numerical speed limit. A separate speed-limit sign may be provided where a specific maximum speed is required.
Why is a general warning sign used instead of a specific warning sign?
It is used when the traffic-sign system does not contain a specific symbol that accurately represents the particular hazard.
Can the danger be temporary?
Yes. A general warning sign may be used for either a temporary or continuing hazard, depending on local signing rules and the circumstances.
Can a supplementary panel indicate the distance to the danger?
Yes. Depending on the country's traffic-sign system, an additional panel may indicate the distance to the hazard, the length of the dangerous section or other useful information.
Does a general danger sign give anyone priority?
No. A danger warning sign does not by itself change the priority rules. Drivers must continue to follow traffic lights, priority signs and the normal right-of-way rules.
Does the warning end immediately after the sign?
Not necessarily. The sign normally warns of a hazard ahead of the sign, and the dangerous situation may extend over a section of road. Supplementary information may indicate its location or length.
24. バス
バスは、公共交通、スクール輸送、私的輸送などで多数の乗客を道路上で運ぶための自動車です。乗用車より乗車定員が多く、座席のみ、立席を含む、または両方の形式があります。
運転免許、乗車定員、速度、シートベルト、バスレーン、停留所、乗降などに特別規則が適用される場合があります。分類や規則は国によって異なるため、現地交通規則に従います。
What is a bus?
A bus is a motor vehicle designed to transport a relatively large number of passengers. It may be used for public transport, school transport, private services or other passenger transport.
What is the difference between a bus and a coach?
A bus is commonly designed for frequent passenger boarding and may allow standing passengers, while a coach is generally designed for longer journeys with passengers seated. Exact legal definitions vary between countries.
Do you need a special driving licence to drive a bus?
Yes. Driving a vehicle designed to carry more than a specified number of passengers normally requires a dedicated bus or passenger-vehicle driving licence.
Can passengers stand on a bus?
Only when the vehicle is designed and approved to carry standing passengers. Coaches and other vehicles designed exclusively for seated passengers must not be used beyond their approved passenger configuration.
Must bus passengers wear seat belts?
Where seat belts are provided and local law requires their use, passengers must wear them correctly. Urban buses designed for standing passengers may have seating positions or operating conditions that differ from coaches.
Can buses use bus lanes?
Yes, where permitted. Bus lanes are commonly reserved for public transport buses, although local signs may also allow taxis, bicycles or other specified vehicles to use them.
Do buses always have priority when leaving a bus stop?
No. Some countries require other drivers to give way to buses leaving designated stops, particularly in urban areas, while others apply the normal merging rules.
Should you take extra care near a stopped bus?
Yes. Passengers may be boarding, leaving or crossing the road near the bus. Reduce speed where necessary and watch carefully for pedestrians emerging from behind or in front of the vehicle.
Do buses have special speed limits?
They can. Some countries impose lower maximum speeds on buses than on passenger cars, particularly on high-speed roads. Different limits may apply to buses and coaches.
Can a bus use a motorway?
Yes, normally. Buses that satisfy the applicable construction and access requirements may use motorways, but they must obey any vehicle-specific speed limits, lane restrictions and other local rules.
25. 警察
警察は、法律の執行、公共安全、道路交通へ影響する状況の管理を担う公的機関です。交通では車両検査、交通取締、事故調査、交通整理、緊急対応などを行います。
道路利用者は警察官など権限を持つ交通整理員の適法な指示に従います。現地法により、警察の指示は一時的に信号、道路標識、通常の交通配置より優先する場合があります。
What is the role of police in road traffic?
Police help enforce traffic laws, manage traffic, investigate collisions and respond to dangerous situations. They may also carry out roadside checks and direct road users.
Must you obey a police officer directing traffic?
Yes. Lawful directions given by an authorised police officer must be followed. In many countries, those directions take precedence over traffic lights, road signs and normal priority rules.
What should you do if police signal you to stop?
Slow down, follow the officer's directions and stop at a safe location as instructed. Do not make sudden movements or continue driving unless directed to do so.
Can police direct you through a red traffic light?
Yes, where authorised by local law. A police officer controlling traffic may instruct road users to proceed even when a traffic light or sign would normally require them to stop.
Can police check your driving documents?
Yes. Police may require drivers to provide documents such as a driving licence, vehicle registration, identification or proof of insurance according to local law.
Can police carry out alcohol or drug checks?
Yes. Traffic police may conduct legally authorised alcohol and drug checks using procedures such as breath, saliva or other approved tests.
Can police temporarily close a road?
Yes. Roads or lanes may be temporarily closed or traffic diverted because of collisions, emergencies, investigations, public events or other safety concerns.
What should you do near police controlling an accident scene?
Reduce speed, remain alert and follow all directions. Do not enter a closed area or interfere with emergency personnel, and leave sufficient space for emergency vehicles.
What should you do when a police vehicle approaches with emergency signals?
Follow the local rules for priority vehicles. Drivers generally have to make sufficient space, give way and stop where necessary so that the emergency vehicle can pass safely.
Can police order a parked vehicle to be moved?
Yes, where local law permits it. Police or another authorised authority may require a vehicle to be moved when it obstructs traffic, creates danger or must be removed for operational reasons.
