    Answer: First, switch off the engine to prevent fire, then assess injuries and request emergency services if needed.

  2. What should a driver do if the accident scene is unsafe?

    • AMove to a safe location away from traffic (if not injured)✓
    • BLeave the area completely and carry on with the delivery run
    • CStand in the carriageway and direct other traffic around it
    • DStay at the scene whatever the danger

    Answer: If the scene is dangerous, move yourself to a place of relative safety away from moving traffic, such as behind a safety barrier. Do not stay in the path of traffic.

  3. When must a driver remain at an accident scene?

    • AOnly if police are present
    • BAlways, unless injured✓
    • CDrivers must stay until released by police
    • DOnly if there are injuries

    Answer: Drivers must remain at the scene unless continuing would cause them injury. Leaving without providing details is a legal offence.

  4. What information must be exchanged at an accident scene?

    • BEach driver's date of birth, employer, and number of penalty points
    • CThe drivers' tachograph card numbers and their daily driving hours

    Answer: Under the Road Traffic Act 1988 s170 a driver involved in an accident must stop and give their name and address, the vehicle owner's name and address and the vehicle registration to anyone with reasonable grounds to ask; if anyone is injured, insurance details must also be produced. Exchanging phone numbers and insurance details is good practice. If details cannot be exchanged at the scene, report to the police as soon as reasonably practicable and within 24 hours.

  5. What is the purpose of warning triangles at an accident scene?

    • ATo make the scene look official to passing motorists
    • BTo record the accident
    • CTo mark the accident location
    • DTo warn approaching traffic of the hazard ahead✓

    Answer: Warning triangles (or lights) alert approaching drivers to the accident ahead, giving them time to slow and avoid a secondary accident.

  6. What should a driver do if their vehicle breaks down on a motorway?

    • AWait inside the vehicle with the hazard warning lights switched on until assistance arrives
    • BPlace a warning triangle 45 metres behind the vehicle and stand next to it
    • CNever use a warning triangle — switch on hazard lights, get behind the safety barrier if possible, and use the roadside emergency phone✓
    • DPlace a warning triangle 150 metres behind the vehicle

    Answer: Highway Code rule 276 says never to use warning triangles on motorways. Rule 277 instead says to switch on hazard lights, get behind the safety barrier where there is one, and call for help, which keeps the driver off the live carriageway. On other roads, rule 276 says to place a warning triangle at least 45 metres behind the vehicle.

  7. What should a driver do if a vehicle is on fire?

    • BLeave it alone, because spilt diesel evaporates within a few minutes

    • DA recovery technique that is used only on a casualty who is still breathing normally

    Answer: CPR is chest compressions with rescue breaths for an unresponsive casualty who is not breathing normally. The Highway Code says that if there are no signs of breathing, start CPR; you do not need training to begin, and prompt action saves lives.
