Rule 283 - The Highway Code

If you are involved in an incident or collision or stop to give assistance

• if possible, stop in a place of relative safety (see Rule 275)
• use your hazard warning lights to warn other traffic
• put on high-visibility clothing if you have it
• ask drivers to switch off their engines
• ask drivers and passengers to stop smoking
• contact the emergency services on 999 and provide full details of the incident location and any casualties. Use an emergency telephone, a mobile telephone, or press the SOS button if your vehicle has one (see Rule 277 on how to identify your location on a motorway or other high-speed road)
• move uninjured people away from the vehicles to a place of relative safety (see Rule 275)
• DO NOT move injured people from their vehicles unless they are in immediate danger
• DO NOT remove a motorcyclist’s helmet unless it is essential and you are trained to do so
• be prepared to give first aid (see First aid on the road and Useful websites)
• stay at the scene until the emergency services arrive
• be prepared to exchange details (see Rule 286).

If you are involved in any other medical emergency, you should contact the emergency services in the same way.
