If other drivers have been involved in a crash, they may need assistance. You may be able to help. First, make sure your vehicle is parked away from the crash, where it won’t obstruct traffic or emergency vehicles. Use warning devices such as reflective triangles to alert other drivers that there has been a crash. Call for emergency services if necessary and stay with injured people until help arrives. However, don’t move injured people unless there is danger of fire or explosion; moving them might make their injuries worse.
