451. Damage
Damage after a traffic accident can affect vehicles, road infrastructure or other property. Damage may be minor, such as scratches or dents, or serious enough to make a vehicle unsafe to drive. After an accident involving only material damage, drivers should make the scene safe, exchange the required information, document the circumstances and notify the insurer when necessary. A damaged vehicle should not be driven if faults involving lights, tyres, steering, brakes, windows or other safety-related parts make continued driving unsafe.

What is material damage in a traffic accident?
Material damage is damage to vehicles, road infrastructure, buildings or other property without bodily injury.
What should you do after an accident with only material damage?
Make the scene safe, exchange the required details, record the damage and circumstances and follow the applicable insurance and reporting rules.
Should you take photos of accident damage?
Yes. Photos of the vehicles, damage, road position, signs and surrounding area can help document what happened and support an insurance claim.
Can you continue driving a damaged vehicle?
Only if the vehicle remains safe and roadworthy. Do not continue driving if the damage affects steering, brakes, tyres, lights, visibility or another safety-critical component.
Should damage be reported to the insurer?
Usually, yes. Insurance policies commonly require an accident or claim to be reported as soon as possible. The exact procedure and deadline depend on the country and policy.
What if you damage property and the owner is not present?
You should follow local rules for identifying yourself and reporting the damage. Leaving without providing the required information can lead to legal consequences.
452. Breakdown
A breakdown occurs when a vehicle can no longer continue safely because of a mechanical, electrical or other technical problem. If possible, move the vehicle away from moving traffic, switch on the hazard warning lights and warn other road users. On high-speed roads, leave the vehicle only when it is safe to do so and wait in a protected place away from traffic. Contact roadside assistance or emergency services when necessary, and do not attempt repairs that put you or others in danger.

What should you do first if your vehicle breaks down?
If possible, move the vehicle to a safe place away from moving traffic, switch on the hazard warning lights and warn approaching road users.
Should you stay inside a broken-down vehicle?
This depends on the location and danger. On high-speed roads, it is often safer to leave the vehicle carefully and wait behind a safety barrier or another protected place when this can be done safely.
Should you use a warning triangle after a breakdown?
Many countries require or recommend a warning triangle when a broken-down vehicle creates a danger or obstruction. The required distance and conditions vary by country.
Should you wear a reflective vest after a breakdown?
In many countries, a high-visibility or reflective vest is required or recommended when leaving a broken-down vehicle near traffic. Check the local rules.
Can you repair a vehicle at the roadside?
Only when it can be done safely. Do not attempt repairs if they expose you to moving traffic or another serious hazard. Roadside assistance is often the safer option.
Who should you call after a breakdown?
Contact roadside assistance when the vehicle cannot continue safely. Call the emergency services when there is immediate danger, injury, fire or another emergency.
453. Total loss
A total loss occurs when a damaged vehicle is considered unsuitable or uneconomical to repair. A vehicle may be declared an economic total loss when the cost of repair is too high compared with its value, or a technical total loss when the damage makes safe restoration impossible or subject to special requirements. An automotive expert or insurer normally assesses the damage, repair cost, vehicle value and salvage value. The exact definition, compensation and rules for repairing or disposing of a total-loss vehicle vary between countries and insurance policies.

What is a total loss?
A total loss means that a damaged vehicle is considered unsuitable or uneconomical to repair because of the extent of the damage, repair cost or applicable technical requirements.
What is an economic total loss?
An economic total loss occurs when repairing the vehicle is no longer financially reasonable compared with its value and, where applicable, its remaining salvage value.
What is a technical total loss?
A technical total loss occurs when the vehicle has suffered such serious structural or other damage that it cannot normally be returned to road use without meeting special technical or legal requirements.
Who decides whether a vehicle is a total loss?
The assessment is commonly made by an automotive expert or insurance company based on the vehicle's condition, value, repair costs and applicable regulations.
Can a total-loss vehicle be repaired?
This depends on the type of total loss and local rules. An economically written-off vehicle may sometimes still be repaired, while a technical total loss may face stricter restrictions or a special approval procedure.
How is compensation for a total-loss vehicle calculated?
The amount depends on the vehicle's value before the damage, salvage value, insurance cover, liability and policy conditions. Different insurance contracts may use different valuation methods.
454. Multiple-vehicle collision
A multiple-vehicle collision is a traffic accident involving three or more vehicles. It can occur when one collision triggers additional impacts, especially in heavy traffic, poor visibility or slippery conditions. These crashes can be difficult to assess because several vehicles may be damaged and responsibility may involve more than one driver. After a multiple-vehicle collision, drivers should make the scene safe, assist injured people, contact emergency services when necessary and carefully document the vehicles, damage and circumstances.

What is a multiple-vehicle collision?
A multiple-vehicle collision is a traffic accident involving three or more vehicles.
What is a chain collision?
A chain collision occurs when an initial crash leads to additional vehicles colliding one after another. It is a common type of multiple-vehicle collision.
What commonly causes multiple-vehicle collisions?
Common factors include tailgating, sudden braking, poor visibility, slippery roads, high speed and heavy traffic.
What should you do after a multiple-vehicle collision?
Protect yourself and others from further danger, check for injuries, contact emergency services when necessary and document the accident. Follow local rules on moving vehicles and reporting the crash.
Should you take photos after a multiple-vehicle collision?
Yes, when it is safe. Photos of the vehicle positions, damage, road conditions, signs and surrounding area can help establish what happened.
Who is responsible in a multiple-vehicle collision?
Responsibility depends on the circumstances. More than one driver may be partly responsible, and insurers, police or courts may need to reconstruct the sequence of impacts.
455. Warning triangle
A warning triangle is a portable reflective safety device used to warn approaching traffic about a stopped, broken-down or crashed vehicle or another obstruction on the road. It should be placed far enough from the hazard to give other drivers time to react and should remain clearly visible. The required distance and situations in which a warning triangle must be used vary between countries, so drivers should know the local rules and keep the triangle easily accessible in the vehicle.

What is a warning triangle?
A warning triangle is a portable reflective device placed on the road to warn approaching traffic about a stopped vehicle, accident or other hazard.
When should a warning triangle be used?
It is generally used when a vehicle is broken down, involved in an accident or creating an obstruction. The exact legal requirements vary between countries.
How far from the vehicle should a warning triangle be placed?
The required distance depends on the country and type of road. Higher-speed roads usually require the triangle to be placed farther away so approaching drivers have more time to react.
Where should the warning triangle be placed?
Place it where it is clearly visible to approaching traffic and where doing so does not put you in unnecessary danger.
Should you use hazard warning lights as well as a warning triangle?
Often, yes. Hazard warning lights and a warning triangle can work together to make a stopped vehicle more visible. The legal requirements vary by country.
Should the warning triangle be easy to reach?
Yes. It is useful to keep it accessible without having to unload large amounts of luggage, especially because it may be needed quickly in a dangerous roadside situation.
456. International Driving Permit
An International Driving Permit (IDP) is a document that translates the information on a national driving licence into a standardised format for use abroad. It can help authorities understand a foreign licence when driving in another country, but it does not replace the original driving licence. Drivers normally need to carry both documents together. Whether an IDP is required depends on the countries that issued the licence and where the person intends to drive, so requirements should be checked before travelling.

What is an International Driving Permit?
An International Driving Permit (IDP) is a standardised document that translates information from a national driving licence for use in other countries.
Is an International Driving Permit a driving licence?
No. An IDP does not replace a valid national driving licence. It is normally valid only when carried together with the licence on which it is based.
When do you need an International Driving Permit?
This depends on where your driving licence was issued and the country where you want to drive. Some countries recognise foreign national licences directly, while others require or recommend an IDP.
Can you use an International Driving Permit without your national licence?
Generally, no. You should carry your valid national driving licence together with the IDP.
Is an International Driving Permit valid everywhere?
No. Recognition depends on international conventions and national law. Drivers should check the requirements of every country they plan to visit.
Where can you obtain an International Driving Permit?
An IDP must be obtained from an authorised organisation or authority in the appropriate country. It should not be confused with unofficial documents sold online as international driving licences.
457. Traffic rules
Traffic rules are laws and regulations that govern how road users behave on public roads. They cover subjects such as speed, priority, overtaking, parking, traffic lights, road signs, lane use and the responsibilities of drivers, cyclists and pedestrians. Traffic rules are designed to organise traffic, reduce conflicts and improve road safety. Rules differ between countries and sometimes between regions, so road users should know the regulations that apply where they are travelling.
What are traffic rules?
Traffic rules are laws and regulations that determine how drivers, cyclists, pedestrians and other road users must behave on the road.
Why are traffic rules important?
Traffic rules help organise traffic, prevent conflicts and reduce the risk of accidents by making the behaviour of road users more predictable.
Are traffic rules the same in every country?
No. Traffic rules vary between countries and can differ in areas such as speed limits, priority, parking, overtaking and permitted road use.
What is the difference between traffic rules and traffic signs?
Traffic rules are the laws governing road use, while traffic signs communicate specific warnings, restrictions, obligations or information to road users.
Do traffic rules apply only to drivers?
No. Traffic rules can apply to drivers, cyclists, pedestrians, motorcyclists and other road users, depending on the rule and type of road.
Do temporary traffic signs override normal traffic rules?
Temporary signs and authorised traffic directions can change how traffic must behave at a particular location. Road users must follow the applicable signs, signals and authorised instructions according to local law.
458. Driving school
A driving school is an organisation that provides professional theory and practical training for learner drivers. Qualified instructors teach traffic rules, vehicle control, observation, manoeuvres and safe driving in real traffic. Depending on the country and licence category, driving-school lessons may be optional, required before obtaining a provisional licence or compulsory after repeated exam failures. Driving schools prepare candidates for the official exams, but the exams themselves are normally conducted by an independent exam centre or licensing authority.
What is a driving school?
A driving school provides professional instruction to help learner drivers prepare for their theory and practical driving examinations.
What do you learn at a driving school?
Training can include traffic rules, road signs, vehicle control, observation, manoeuvres, hazard awareness and driving safely in normal traffic.
Are driving-school lessons mandatory?
This depends on the country, licence category and chosen training route. Some learners may practise privately, while others must complete a minimum number of professional lessons.
Is a driving school the same as an exam centre?
No. A driving school provides training, while an exam centre officially assesses whether the candidate meets the requirements for a driving licence.
Can a driving school arrange the practical exam?
Often, yes. When a candidate takes the practical exam through a driving school, the school may book the appointment and provide the examination vehicle, depending on local rules.
How should you choose a driving school?
Choose an authorised or recognised driving school where required, and compare factors such as instructor qualifications, training options, availability and cost.
459. Traffic signs
A traffic sign is a standardised visual symbol placed along roads to guide, warn, or regulate drivers, cyclists, and pedestrians. These signs provide essential information about road conditions, rules, directions, and potential hazards, helping to ensure safety and smooth traffic flow. They come in various shapes and colours—such as triangular warning signs, circular prohibitory or mandatory signs, and rectangular information signs—each designed for quick recognition and clear understanding.
