Road Safety, Accident Procedures and First Aid

Domain 6, Road Safety, Accident Procedures and First Aid, tests what a heavy-vehicle driver does in the first minutes after a crash: protect the scene, call for help, give basic first aid and preserve evidence without creating a second incident. The exam also checks prevention duties such as securing the vehicle and warning other traffic.

Core rules

  • Stop, switch off the engine, apply the parking brake and turn on hazard lights. Place a warning triangle or other visible warning at a safe distance behind the scene, farther on a fast road or a blind bend. Do not stand in a live lane.
  • Call the police, fire service or ambulance using the national emergency numbers, and give a precise location, number of casualties, vehicle types and any fire or spill risk.
  • First aid priorities: danger, response, airway, breathing, circulation. Do not move an injured person unless there is immediate danger such as fire, fuel or traffic. Control severe bleeding with direct pressure; keep the casualty warm and monitor breathing. Do not remove a motorcycle helmet unless the airway is blocked and you have been trained.
  • Do not admit liability, bargain with crowds or leave the scene. Exchange details, record witnesses and photographs if safe, and report to the insurer and transport operator.

Worked example

A truck collides with a motorcycle at dusk. The rider is unconscious but breathing. The driver should first secure the scene: hazards on, triangle behind the truck, engine off, and keep bystanders back. Then call emergency services, check the rider’s airway and breathing without moving the neck unnecessarily, control bleeding and keep the rider warm. The helmet stays on unless the airway cannot be managed. The driver records the scene and waits for authorities; moving the rider into a passing car could worsen a spinal injury.

Traps

  • Moving casualties first and securing the scene second.
  • Leaving the scene to find a phone or to avoid a crowd.
  • Giving food or drink to an injured person.
  • Assuming a fuel spill is harmless; a hot exhaust or cigarette can ignite it.
