Klipspringer:Lesson learnt: Next time take pictures, get a written statement from the other person involved. If need be, drive straight down to the police station with them to do this. Don't leave it. Many people out there are dishonest.
Take pictures by all means but the other driver only has to supply contact details and name of insurance co if applicable. His insurance co will have made it a condition that he doesn't admit anything and I doubt the Police will be interested unless there's an injury.
