1. The driver of a vehicle involved in an accident resulting in injury to or death of any person shall immediately by the quickest means of communication give notice of such accident to the sheriff of the county in which said accident occurred, or the nearest office of the state patrol, or to any other peace officer as near as practicable to the place where the accident occurred.
