The offense of leaving the scene of an accident that you caused and its elements vary in each State in this country. However, in general there are laws requiring the person who caused the accident (if not seriously injured as a result) to remain at the scene until law enforcement shows if the accident is serious (property damages exceeding $250.00 or more as an example) or personal injury to you or a third person.From the facts contained in your question, it seems unlikely that you will be charged for leaving the accident's scene. In retrospect, it would have been a good idea to have left a note at the scene of the accident with your name, address, and telephone number on it and the reason why you left.
