If you really want to screw up your car wreck case, trust the other driver. Don't take any pictures, don't call the police, don't fill out any witness statement. Don't tell your insurance company you were even in a wreck. That's how you screw up your case. Unfortunately, nobody tries to screw up their case, but they don't know what to do. That's the one thing I want to make sure that anybody who's been in a wreck, they know some basics is you want to make sure that you are prepared if that other driver who says, "Oh yeah, I'll take care of everything," changes his or her mind. So you want to make sure that you call the police, you fill out an accident report, you tell your insurance company your version, before somebody else calls and tells them theirs. You want to make sure that you get treated, even though you feel fine, you think everything's going to be okay, go get checked out. I know you don't want to screw up your case, but if you do those basic things, you're going to be a whole lot better off.
