Mistake #3. Fail to Collect Evidence at the Accident Scene

Don't assume that the police will talk to every witness or that all of the witnesses will wait around for the police to show up.  If you are able, write down the names, addresses and telephone numbers of all witnesses who stopped to assist you.  Also take a few photos with your cell phone if you are able.  Skid marks, collision debris in the road, and damage to the other car are often hard to get and easily lost if not captured right away.
