2. Get help
If you can do so safely, try to get the help of bystanders. Get someone to call the appropriate emergency services on 999 or 112 as soon as possible. They’ll need to know the exact location of the incident (including the direction of traffic, for example, northbound) and the number of vehicles involved. Try to give information about the condition of any casualties, for example, if anyone is having difficulty breathing, is bleeding heavily, is trapped in a vehicle or doesn’t respond when spoken to.
