First, make sure that you call the police to the accident scene. It is usually helpful if the police take an accident report. It will help you especially if the other driver was entirely at fault.
Second, your auto accident injury lawyers will want you to see a doctor as soon as possible. The longer you delay seeing the doctor, the more likely the insurance company will fight your claim.
Third, collect as much accident evidence as you can after the accident. Your attorney will also do so, but you will be able to take photos of the car positions before the police move them. Also, take pictures of your injuries and up-close images of property damage.
