Mistake #4. Tell The Other Driver That You Are "Okay"

Even if the other driver is very nice, and appologetic, do not tell him or her that you are Okay.  Tell them of any complaints that you have no matter how small, or don't talk to them at all if you can get their contact information from the police or otherwise.  Tell them if you are "shaken up" or have a headache or feel stiff.  Any of those is better than telling them that you are fine when you are not.  Anything you say is admissible against you.  If you report that you are "Ok" or "not hurt" that is the first thing that the other driver will report to his/her insurance company, and that is a statement that you will hear them testify at trial that you said.  Many soft-tissues swell over night after an accident, and you may feel awful the next morning after an accident that you thought did not injure you.
