Don't worry about this one nicole1991, this is one in the bag for you. So don't lose any sleep at all.
Like all accidents be sure you make a practice drawing of the accident site before you commit it to the proper form. AWAYS draw several until you are 100% happy that that is how it looked. Then copy it to the insurance form.
Again don't commit anything to paper until you have partciced it out a few times. And make sure all the wording is correct.
Also get any witness's name and address. This is VERY important.
FiINALLY and most importantly, if you witness an accident give your name and address to the injured party. It makes life a hell of a lot easier if you have a witness.
One day you too might need help!!
