201. Traffic enforcement camera
A traffic enforcement camera is an automated or remotely operated camera system used to detect traffic violations. Depending on the system, cameras may measure speed, detect vehicles passing a red light, read number plates or monitor other prohibited behaviour. Some cameras measure a vehicle at one specific location, while systems such as section control measure average speed over a longer distance. The types of cameras used, offences they can detect and enforcement procedures vary between countries.
What is a traffic enforcement camera?
A traffic enforcement camera is a camera system used to detect or record traffic violations for enforcement purposes.
What violations can traffic enforcement cameras detect?
Depending on the system, cameras can detect speeding, red-light violations, prohibited lane use, insufficient following distance and other traffic offences.
What is a speed camera?
A speed camera measures the speed of vehicles at a particular location and can record vehicles exceeding the applicable speed limit.
What is a red-light camera?
A red-light camera records vehicles that pass a traffic signal after it has turned red. Some systems can also measure vehicle speed.
Is section control a traffic enforcement camera?
Yes. Section control uses cameras at multiple points to calculate a vehicle's average speed over a defined road section rather than measuring speed at a single location.
Do all traffic cameras enforce traffic laws?
No. Some cameras are used only for traffic monitoring, traffic management or incident detection. A traffic camera is therefore not necessarily an enforcement camera.
202. Accident
An accident is an unexpected event involving one or more road users that causes damage, injury or both. After a traffic accident, the first priority is safety: stop, protect the scene, assist injured people when possible and contact the emergency services when necessary. Drivers should avoid creating additional danger, exchange the required information and follow local rules for reporting the accident. Serious crashes may require the vehicles to remain in place until the police arrive.

What should you do first after a traffic accident?
Stop and make the scene as safe as possible. Warn approaching traffic, check whether anyone is injured and call the emergency services when necessary.
Should you move the vehicles after an accident?
This depends on the circumstances and local law. After a minor collision with no injuries, vehicles may need to be moved out of the traffic flow when it is safe. After a serious injury accident, they may need to remain in place for investigation.
What information should drivers exchange after an accident?
Drivers commonly exchange names, contact details, vehicle information and insurance details. The exact legal requirements vary between countries.
When should the police be called after an accident?
Police should generally be contacted when there are injuries, serious damage, disagreement, suspected offences or difficulty identifying the people involved. Local reporting rules may require police involvement in additional situations.
What is an accident report form?
An accident report form records information about the vehicles, drivers, damage and circumstances of a collision and can help insurers process the claim.
Can you leave the scene of an accident?
Drivers and other involved persons are normally required to stop and fulfil their legal duties. Leaving without doing so may constitute a serious offence such as hit-and-run.
203. Injuries
Injuries after a traffic accident can range from minor cuts and bruises to serious or life-threatening trauma. The first priority is to prevent further danger, contact the emergency services when necessary and provide appropriate assistance within your abilities. Avoid moving a seriously injured person unless leaving them in place creates an immediate danger, and follow the instructions of emergency operators or trained responders. Even when injuries initially appear minor, medical assessment may be necessary because some symptoms can develop later.

What should you do if someone is injured in a traffic accident?
Make the scene as safe as possible, call the emergency services when necessary and provide assistance within your abilities. Follow instructions given by emergency operators or trained responders.
Should you move an injured person after an accident?
Generally, avoid moving a seriously injured person unless they face an immediate danger from traffic, fire or another hazard. Unnecessary movement can worsen certain injuries.
Should you remove a motorcyclist's helmet after an accident?
Do not routinely remove a helmet from an injured motorcyclist. Helmet removal may require special care, particularly when a head, neck or spinal injury is possible. Follow emergency-service instructions unless immediate action is necessary to preserve life.
Can someone be seriously injured without obvious wounds?
Yes. Internal injuries, concussion and other trauma may not be immediately visible. Seek medical assistance when there is concern about the person's condition.
What information should you give emergency services?
Give the exact location, what happened, the number of injured people and any immediate dangers. Stay on the line and follow the operator's instructions.
Should you give first aid after a traffic accident?
Provide first aid that you are trained and able to give safely. Do not put yourself or others in additional danger, and follow professional instructions whenever possible.
204. Nosebleed
A nosebleed is bleeding from one or both nostrils and is usually caused by small blood vessels inside the nose. Most nosebleeds are minor, but they can distract a driver and may make it unsafe to continue driving. If a nosebleed starts while driving, stop at a safe place when possible. Sit upright, lean slightly forward and pinch the soft part of the nose continuously for about 10–15 minutes. Do not tilt the head backwards because blood can run into the throat. Seek medical help if the bleeding is severe, follows a serious injury or does not stop.
What should you do if you get a nosebleed while driving?
Stop at a safe place as soon as possible. Sit upright, lean slightly forward and pinch the soft part of the nose continuously for about 10–15 minutes.
Should you tilt your head back during a nosebleed?
No. Keep your head slightly forward so blood does not run into the throat, where it can cause choking, coughing or vomiting.
How long should you pinch your nose?
Pinch the soft part of the nose continuously for about 10–15 minutes before checking whether the bleeding has stopped.
When should you seek medical help for a nosebleed?
Seek medical help if the bleeding is heavy, does not stop after sustained pressure, follows a significant head or facial injury, causes weakness or dizziness, or makes breathing difficult.
Can you continue driving with a nosebleed?
Only if the bleeding has stopped and you feel fully able to drive safely. If the nosebleed distracts you, affects visibility or makes you feel weak or unwell, stop and do not continue until it is safe.
Can blood-thinning medication make nosebleeds more serious?
Yes. Medicines that reduce blood clotting can make bleeding more difficult to stop. Seek medical advice if bleeding persists or you are concerned.
205. 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.
206. 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.
207. 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.
208. 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.
209. 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.
210. 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.
