If you are involved in a crash or stop to give assistance

• use your hazard warning lights to warn other traffic
• ask drivers to switch off their engines and stop smoking
• arrange for the emergency services to be called immediately with full details of the incident location and any casualties (on a motorway, use the emergency telephone which allows easy location by the emergency services. If you use a mobile phone, first make sure you have identified your location from the marker posts on the side of the hard shoulder)
• move uninjured people away from the vehicles to safety; on a motorway this should, if possible, be well away from the traffic, the hard shoulder and the central reservation
• do not move injured people from their vehicles unless they are in immediate danger from fire or explosion
• do not remove a motorcyclist's helmet unless it is essential to do so
• be prepared to give first aid as shown on pages 131-133
• stay at the scene until emergency services arrive.

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