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. 自動車専用道路
自動車専用道路は、一般道路より高い速度で通過交通を効率よく流すことを目的とした道路です。多くの場合、アクセスが制限され、複数車線、分離車道、立体交差を備えますが、設計や法的扱いは国によって異なります。
自動車専用道路が必ずしも高速道路とは限りません。交差点、信号、直接出入り口が存在する場合もあり、利用可能な道路利用者、速度制限、特別規則は現地の標識と規則により決まります。
How can you recognise an expressway?
An expressway may be identified by a special road sign or by its road classification. It often has multiple lanes, limited access and junctions designed for faster traffic, but its exact appearance differs between countries.
Is an expressway the same as a motorway?
No. A motorway normally has full access control and stricter design and traffic rules. An expressway may have partial access control, ordinary intersections, traffic lights or direct entrances. The legal distinction varies between countries.
Is an expressway always divided?
Not necessarily. Many expressways have separate carriageways for opposing traffic, but some countries also classify undivided roads as expressways. Drivers should rely on local signs and road rules rather than the road’s appearance alone.
Who may use an expressway?
Expressways are generally intended for motorised traffic. Pedestrians, cyclists, animals, mopeds and slow vehicles may be restricted or prohibited, but the permitted road users depend on local law and traffic signs.
What is the speed limit on an expressway?
There is no universal expressway speed limit. The applicable limit depends on the country, road design, location, vehicle category and posted signs. An expressway sign does not always impose a particular speed by itself.
Can an expressway have intersections or traffic lights?
Yes. Unlike a motorway, an expressway may have level intersections, roundabouts, pedestrian crossings or traffic lights. Drivers must therefore remain prepared for crossing traffic and changes in priority.
How should you enter an expressway?
Use an entrance or acceleration lane where one is provided, observe approaching traffic and enter only when there is a safe gap. Where the road has an ordinary intersection, follow the applicable priority signs and local rules.
Which lane should you use on an expressway?
Follow the local keep-left or keep-right rule, lane arrows and traffic signs. Lanes nearer the centre are commonly used for overtaking, but special lane restrictions may apply to heavy vehicles or particular destinations.
Can you stop, park, reverse or make a U-turn?
These actions are often restricted on expressways because of the speed and flow of traffic. Stop or park only where permitted, and never reverse or make a U-turn unless the road design and local rules clearly allow it.
What should you do after a breakdown?
Move the vehicle away from moving traffic when this can be done safely, activate the hazard warning lights and follow the local breakdown procedures. Use a warning triangle or safety vest where required and wait in a protected location away from traffic.
4. 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.
5. 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.
6. 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.
7. バス停
バス停は、路線バスが乗客を乗降させるため指定された場所です。標識、路面標示、停留所施設、待合所などで示されます。
バス停付近では、バスの発進、道路を横断する乗客、停車車両で視界が遮られる危険に注意します。停止・駐車規制やバスへの優先規則は国や地域によって異なります。
What is a bus stop?
A bus stop is a designated location where buses stop so that passengers can board or leave the vehicle.
What should you watch for near a bus stop?
Watch for buses entering or leaving the stop, passengers near the roadway and pedestrians who may cross the road.
Can you park at a bus stop?
Parking or stopping at or near a bus stop is often restricted or prohibited so that buses can reach the stop safely. The exact restrictions depend on local traffic rules.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 市街地境界
市街地境界は、道路交通上、市街地・都市区域が始まるまたは終わる境界です。地名標識や市街地標識で示され、都市速度制限、駐車規則など特別規則の開始・終了地点となることがあります。
交通上の市街地境界は自治体の行政境界と必ずしも一致しません。法的意味はその国の道路標識と交通規則によります。
What is a city limit?
A city limit marks the boundary of a city, town, village, locality or municipality. On roads, it is often indicated by a place-name or boundary sign.
Does a city-limit sign always mark a built-up area?
No. A city-limit or locality sign may simply identify a place or administrative boundary. A legally defined built-up area can use a different sign or definition.
Does passing a city-limit sign always change the speed limit?
No. In some countries a locality or boundary sign has consequences for traffic rules, while in others it mainly identifies the place. Drivers must follow the traffic signs and rules that apply in that country.
Is a city limit the same as a municipal boundary?
Not always. Some signs indicate an administrative municipal boundary, while others identify a city, town, village or locality without exactly following the municipality's legal boundary.
What is the difference between a city limit and a built-up area?
A city limit identifies the boundary of a named place or administrative area. A built-up area is a traffic-law concept that may affect rules such as default speed limits. The two boundaries can coincide, but they do not have to.
16. ナンバープレート
ナンバープレート(登録番号標または車両番号標)は、登録当局から車両へ割り当てられた固有の登録識別番号を表示するプレートです。車両登録、交通取締、税、保険、駐車管理などで車両を識別するために使われます。
外観、形式、取付位置、必要枚数は国や車種で異なります。必要なプレートを正しく取り付け、はっきり見え、読み取れる状態に保ち、紛失、盗難、破損、交換時には現地規則に従います。
What is a licence plate?
A licence plate is a plate displaying the registration identifier assigned to a vehicle. It allows authorities and other authorised systems to identify the vehicle's registration.
Is a licence plate the same as a registration plate?
Yes. Licence plate, registration plate and number plate are different terms commonly used for the plate displaying a vehicle's official registration number.
Does every vehicle need a licence plate?
Most motor vehicles used on public roads must display one or more registration plates, but requirements differ for motorcycles, trailers, agricultural vehicles and other special vehicle categories.
Do vehicles need both front and rear licence plates?
This depends on the country and vehicle type. Cars commonly require front and rear plates, while motorcycles and certain other vehicles may require only a rear plate.
Must a licence plate remain visible?
Yes. A required registration plate must normally remain clearly visible and readable. It should not be hidden by luggage, dirt, accessories or other objects.
Can you modify a licence plate?
Generally no. Changing the characters, colours, dimensions or appearance of an official plate may make it invalid or illegal. Plates and authorised reproductions must comply with local specifications.
What should you do if a licence plate is lost or stolen?
Follow the local reporting and replacement procedure. Many countries require the loss or theft to be reported to the police or vehicle-registration authority before a replacement plate can be issued.
Can you drive with a damaged licence plate?
A plate must remain legible and compliant with local requirements. If damage prevents it from being read or makes it invalid, it should be replaced according to the local registration procedure.
Can a licence plate be personalised?
Some countries allow motorists to request a personalised registration combination. The available characters, formats and prohibited combinations are determined by the registration authority.
Does a licence plate stay with the vehicle when it is sold?
This varies between countries. In some systems the plate remains with the vehicle, while in others it remains associated with the registered holder and may be retained or returned when the vehicle is sold.
17. 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.
18. 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.
19. 救急車
救急車は、緊急医療の提供や患者輸送のため装備・使用される車両です。医療機器と訓練された職員を乗せ、搬送中に治療する場合があります。
緊急出動中は警光灯とサイレンを使用し、特別な優先権や一部交通規則の例外が認められる場合があります。他の道路利用者は現地規則に従い、十分な通路を空け、進行を妨げない必要があります。
What is an ambulance?
An ambulance is a specially equipped vehicle used to provide emergency medical assistance and transport sick or injured people.
When does an ambulance have priority?
This depends on the local traffic rules and warning signals being used. Ambulances responding to emergencies commonly use flashing lights and a siren to indicate that other road users must make way.
What should you do when an ambulance approaches?
Remain calm and make sufficient space for it to pass. Slow down or stop where necessary, but avoid sudden or dangerous manoeuvres.
Should you stop immediately when you hear an ambulance siren?
Not necessarily in your exact position. Move or stop in a way that creates a safe passage without blocking an intersection, pedestrian crossing or another part of the road needed by the ambulance.
Can an ambulance pass a red traffic light?
Emergency vehicles may be allowed to pass a red light during an urgent response under special legal conditions. The precise rules differ between countries, and the ambulance driver must still take appropriate precautions.
Can an ambulance exceed the speed limit?
Many countries permit emergency vehicles to depart from certain normal speed rules during an urgent mission, subject to safety requirements and national legislation.
Can an ambulance drive through a traffic queue?
Yes, when responding to an emergency and legally permitted to do so. Other road users should create space and keep emergency corridors or access routes clear where required.
Can you follow an ambulance through traffic?
You should not use the passage created for an ambulance as a way to bypass congestion. Maintain a safe distance and continue to obey the normal traffic rules.
Do ambulances always use their sirens?
No. The use of warning lights and sirens depends on the urgency of the mission and local regulations. An ambulance transporting a patient does not necessarily need to use emergency signals throughout the journey.
What should you do near a stationary ambulance?
Reduce speed and remain alert. Medical personnel, patients or other emergency workers may be entering the road, and the ambulance may need to move unexpectedly.
20. 欧州排出ガス基準
欧州排出ガス基準(Euro基準)は、車両・エンジンの汚染物質排出上限に基づく欧州の車両分類です。Euro 4、Euro 5、Euro 6など後続基準ほど、窒素酸化物、粒子状物質、一酸化炭素、炭化水素などの上限が厳しくなりました。
車両のEuro基準は型式認証時に決まり、車種、燃料、認証時の排出法規などに左右されます。低排出ゾーンの進入条件にも使われますが、具体的規則は国・都市で異なります。
What is a European emission standard?
A European emission standard, or Euro standard, classifies vehicles according to the emissions requirements they had to satisfy when approved for use in the European market.
What do Euro 4, Euro 5 and Euro 6 mean?
They are successive generations of European emission requirements. In general, a higher Euro number represents a newer and stricter emissions standard, although the exact limits differ according to vehicle and fuel type.
Which pollutants do Euro standards regulate?
Depending on the vehicle and standard, limits apply to pollutants such as nitrogen oxides, particulate matter, carbon monoxide and hydrocarbons. Newer standards also regulate additional environmental aspects.
Is the Euro standard the same as a vehicle's CO2 emissions?
No. Euro standards primarily regulate harmful air pollutants from vehicles. Carbon-dioxide emissions and fuel or energy consumption are subject to separate measurements and regulatory requirements.
How can you find a vehicle's Euro standard?
The Euro standard may appear on the vehicle registration certificate, certificate of conformity or other official vehicle documentation. Its location and format vary between countries.
Does the year of a vehicle determine its Euro standard?
The date of first registration can provide an indication, but it does not always determine the standard with certainty. The official vehicle documents or type-approval information provide the more reliable classification.
Can petrol and diesel vehicles with the same Euro number have different emission limits?
Yes. The applicable emission limits and testing requirements can differ according to the vehicle category, engine and fuel type even when vehicles belong to the same general Euro generation.
Can the Euro standard affect access to a low-emission zone?
Yes. Many low-emission zones use the vehicle's Euro standard together with factors such as fuel type and vehicle category to determine whether it may enter.
Does installing a particulate filter automatically change the Euro standard?
Not normally. The official Euro standard is linked to the vehicle's approved emissions classification. Retrofitting emission-control equipment does not necessarily result in a different official Euro classification.
What is Euro 7?
Euro 7 is the latest European emissions framework for road vehicles. It builds on earlier Euro standards and also introduces requirements covering areas such as non-exhaust particle emissions and battery durability.
21. ポットホール
ポットホールは、摩耗、天候、水、反復荷重、舗装劣化などにより路面に生じる穴・窪みです。大きさ・深さはさまざまで、凍結、豪雨、反復交通で悪化することがあります。
操舵、制動、車両安定性へ影響し、タイヤ、ホイール、サスペンションを損傷することがあります。前方路面を確認し、速度を調整し、危険な急操作を避けます。
What is a pothole?
A pothole is a hole or depression that develops in a road surface when the pavement becomes damaged or deteriorates.
How do potholes form?
Potholes can develop through a combination of water, temperature changes, traffic loads and deterioration of the road material. Cracks can gradually expand until pieces of the surface break away.
Why are potholes dangerous?
A pothole can cause a vehicle to change direction suddenly, lose stability or suffer tyre, wheel or suspension damage. Deep potholes can present a particularly serious hazard at higher speeds.
What should you do when you see a pothole?
Reduce speed when necessary, maintain control of the vehicle and avoid abrupt steering or braking. Only move around the pothole when this can be done safely without endangering other road users.
Should you brake while driving through a pothole?
If possible, reduce your speed before reaching the pothole. Sudden heavy braking or steering while passing over a damaged surface can make the vehicle less stable.
Are potholes particularly dangerous for motorcycles?
Yes. A pothole can disturb the steering or balance of a motorcycle and may cause the rider to lose control.
Are potholes dangerous for cyclists?
Yes. Bicycle wheels can be strongly affected by deep holes or sharp edges, particularly when the cyclist has little time or space to avoid the hazard.
Can a pothole damage a car?
Yes. Severe impacts can damage tyres, wheel rims, suspension components, steering parts or wheel alignment.
Should you swerve suddenly to avoid a pothole?
No. A sudden evasive movement may create a greater danger by bringing the vehicle into conflict with cyclists, pedestrians, oncoming traffic or vehicles in another lane.
Can a warning sign indicate potholes ahead?
Yes. Depending on the country's traffic-sign system, an uneven-road or general-danger warning sign may be used where poor road conditions create a significant hazard.
22. 通路
通路は、主に歩行者向けの比較的狭い経路で、許可されている場合はその他の道路利用者や小型車両も利用できます。市街地、農村、公園、森林、道路間などに設けられ、舗装されている場合と未舗装の場合があります。
通路は必ずしも歩道や自転車道と同じではありません。利用できる道路利用者は、その法的区分、幅、交通標識、地域規則によって決まります。
What is a path?
A path is a relatively narrow route intended primarily for pedestrians and, where permitted, other road users or small vehicles.
Is a path the same as a footpath?
Not necessarily. A footpath is specifically intended for pedestrians, while a path may also permit cyclists or other users according to local rules.
Is a path the same as a cycle path?
No. A cycle path is specifically designated for bicycles and other permitted users. An ordinary path does not automatically have that legal status.
Can cyclists use a path?
This depends on the legal status, width and signs applying to the path. Some paths permit cyclists, while others are reserved for pedestrians or particular users.
Can motor vehicles use a path?
This depends on local law. Some paths prohibit motor vehicles entirely, while narrow vehicles may be permitted on other paths unless traffic signs restrict access.
Can a path be part of the public-road network?
Yes. A narrow path can legally form part of the public-road network even when it is unsuitable for ordinary cars.
Does a path need to be paved?
No. Paths can be paved, gravelled, compacted or unsurfaced depending on their location and purpose.
Can traffic signs restrict access to a path?
Yes. Signs can reserve a path for particular road users or prohibit certain vehicles, regardless of whether they could physically fit on it.
Who has priority when a path joins a larger road?
The applicable local priority rules determine who must give way. Special rules often apply when a minor path joins an ordinary road.
Can pedestrians and cyclists share a path?
Yes, where both are permitted. Faster users should adapt their speed and avoid endangering or unnecessarily obstructing pedestrians.
Can a path cross another road?
Yes. At the crossing, users must follow the applicable priority signs, traffic lights, road markings and general right-of-way rules.
Is every narrow route legally a path?
No. Its legal classification depends on the definitions and regulations of the country concerned. A narrow route might instead be a footpath, cycle path, private access road or another type of facility.
23. 粒子状物質
粒子状物質(particulate matter、PM)は、空気中に浮遊する微小な固体粒子または液滴です。道路交通では、排気ガス、ブレーキ摩耗、タイヤ摩耗、路面摩耗のほか、通過車両が巻き上げるほこりからも発生します。
粒子状物質は一般に粒径で分類されます。PM10は直径およそ10マイクロメートル以下、PM2.5はおよそ2.5マイクロメートル以下のより細かい粒子を指します。車両排出ガス基準、粒子フィルター、大気質対策などにより、これらの汚染物質への曝露低減が図られます。
What are particulates?
Particulates, or particulate matter, are very small solid particles or liquid droplets suspended in the air.
What are PM10 and PM2.5?
PM10 refers to particles with a diameter of up to approximately 10 micrometres. PM2.5 refers to finer particles with a diameter of up to approximately 2.5 micrometres.
Where do traffic particulates come from?
Road traffic can produce particles through engine exhaust, brake wear, tyre wear and road-surface wear. Passing traffic can also resuspend dust already present on the road.
Are diesel vehicles a source of particulates?
Yes. Combustion in diesel engines can produce very small soot particles. Modern diesel vehicles commonly use particulate filters to capture a large proportion of these exhaust particles.
What is a particulate filter?
A particulate filter is an exhaust-treatment device designed to trap particulate matter produced by an engine. Diesel particulate filters are commonly known as DPFs.
Do petrol engines produce particulates?
Yes. Petrol engines can also produce particulate emissions, particularly certain direct-injection engines. Appropriate emission-control systems may therefore include particulate filters.
Do electric vehicles produce particulates?
Fully electric vehicles produce no exhaust particulates from a combustion engine, but particles can still result from tyre wear, road wear and braking.
Are brake and tyre particles regulated?
Vehicle-emission regulation is increasingly addressing non-exhaust emissions. The European Euro 7 framework includes requirements concerning brake-particle emissions and tyre abrasion.
Is particulate matter the same as CO2?
No. Particulate matter consists of tiny airborne particles, while carbon dioxide is a gas. They are different types of vehicle emissions and are regulated for different environmental reasons.
How can vehicle particulate emissions be reduced?
Measures include effective particulate filters, cleaner vehicle technologies, correctly maintained emission-control systems and reductions in brake, tyre and road-wear emissions.
24. 大気汚染
大気汚染は、人の健康、環境、生態系へ悪影響を与える濃度で、気体、粒子、その他の物質が空気中に存在する状態です。道路交通は排気ガスに加え、ブレーキ摩耗、タイヤ摩耗、道路粉じんなど非排気由来の排出によっても大気汚染へ寄与します。
交通に関連する主な汚染物質には、窒素酸化物、粒子状物質、一酸化炭素、揮発性有機化合物があります。車両から直接排出されるものもあれば、大気中の化学反応で生成されるものもあります。車両排出ガス基準、よりクリーンな技術、交通管理対策などが排出削減に使われます。
What is air pollution?
Air pollution is contamination of the air by gases, particles or other substances that can adversely affect human health, the environment or ecosystems.
How does road traffic cause air pollution?
Vehicles produce pollutants through fuel combustion, exhaust systems, brake wear, tyre wear and road-surface interaction. Moving traffic can also resuspend dust already present on the road.
Which air pollutants are associated with road traffic?
Important traffic-related pollutants include nitrogen oxides, particulate matter, carbon monoxide and volatile organic compounds. Their relative importance depends on the vehicle, fuel and driving conditions.
What is nitrogen dioxide?
Nitrogen dioxide (NO2) is an air pollutant associated particularly with combustion processes and road traffic. High concentrations are commonly found near busy roads and densely trafficked urban areas.
What is particulate matter?
Particulate matter consists of tiny solid particles or liquid droplets suspended in the air. Road traffic can produce particles from exhaust, brakes, tyres and road surfaces.
Is CO2 the same as ordinary air pollution?
No. Carbon dioxide is primarily regulated as a greenhouse gas because of its contribution to climate change. Local air-quality pollution generally focuses on substances such as nitrogen dioxide, particulate matter, ozone and other pollutants that directly affect air quality and health.
Do electric vehicles cause air pollution?
Fully electric vehicles produce no combustion-engine exhaust emissions while driving, but they can still contribute to non-exhaust particulate emissions through tyres, brakes and road wear.
Can air pollution be worse near busy roads?
Yes. Concentrations of traffic-related pollutants can be higher close to heavily trafficked roads because many emissions occur close to ground level and near where people live and travel.
What is a low-emission zone?
A low-emission zone is an area where access by more polluting vehicles is restricted in order to reduce traffic-related air pollution. Access criteria may depend on factors such as fuel type, vehicle category and emission standard.
How can traffic-related air pollution be reduced?
Measures include cleaner vehicles, stricter emission standards, effective emission-control equipment, low-emission zones, public transport, cycling and walking, as well as traffic-management measures that reduce unnecessary congestion and emissions.
25. ラッシュアワー
ラッシュアワーは、多くの人が通勤、通学、その他の定期的な移動を行うため、道路や公共交通網の需要が特に高くなる時間帯です。通常、平日の朝と夕方から夜にかけて発生します。
ラッシュ時には渋滞、低速走行、移動時間の増加、頻繁な停止が生じます。運転者は安全な車間距離を保ち、焦らず、交通状況の変化を予測し、臨時または動的な交通管理措置に従います。
What is rush hour?
Rush hour is a period when unusually large numbers of people travel at the same time, resulting in increased traffic and often congestion.
When does rush hour occur?
Rush hour commonly occurs during the morning and late afternoon or evening on working days, but the exact times vary according to the city, road and local travel patterns.
Does rush hour always last one hour?
No. The term does not mean that congestion lasts exactly one hour. In busy urban areas, peak traffic conditions may continue for several hours.
Why does traffic become congested during rush hour?
Congestion develops when traffic demand approaches or exceeds the available road capacity. Intersections, merging traffic, collisions, roadworks and weather can make the congestion worse.
Should you increase your following distance in rush-hour traffic?
Yes. Leave sufficient distance to react to sudden braking and frequent changes in traffic speed. Avoid following another vehicle too closely even when traffic is moving slowly.
Should you frequently change lanes during congestion?
Unnecessary lane changes can create additional conflicts and may not significantly reduce journey time. Choose an appropriate lane, observe surrounding traffic and change lane only when it can be done safely.
Can speed limits change during rush hour?
Yes. Roads equipped with variable traffic management may display lower speed limits during congestion. Drivers must follow the speed limit currently indicated.
What is a rush-hour lane?
A rush-hour lane is an additional traffic lane that can be opened during busy periods to increase road capacity. It may use a lane or shoulder that is closed to normal traffic at other times.
Can you use a rush-hour lane whenever traffic is congested?
No. Such a lane may only be used when traffic signals or signs indicate that it is open. Never assume that congestion alone permits its use.
How can you prepare for a journey during rush hour?
Check current traffic conditions and expected journey times, allow additional travel time and consider an alternative route, departure time or mode of transport where appropriate.
