Laws RTA1988, sects 35 &163, and as amended by TMA 2004, sect 6 

282. When passing the scene of an incident or crash do not be distracted or slow down unnecessarily (for example if an incident is on the other side of a dual carriageway). This may cause a collision or traffic congestion, but see Rule 283, below. 

283. 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
