- Stop the car - failing to do so is an offence
- Switch off the engine and turn on the hazard lights
- Check for any injuries to yourself or your passengers. Call an ambulance if necessary
- Call the police - 999 or 101 depending on the situation
- Give your details to anyone else involved
- Collect details from any other drivers, passengers or witnesses
- Take photos if necessary
- Contact your insurer
Not much change then. My thoughts were mostly around #4 - "Give your details"
I know that you are obliged to give your name and address to anyone else involved, but there are some circumstances where I would not really want the other parties to know where I live.
Another website suggests getting details of any passengers as well as independent witnesses. That might also be problematic.
#7 - Taking photos is one piece of advice that I would heartily endorse. If you can, you want to get details of the damage, positions on the road, any relevant signage, and pictures of passengers in the other vehicle(s).
I would be interested to see comments.
