Best practice guide for what you need to do in case you are in an auto accident in NH

If you are involved in an accident or collision in New Hampshire, you must be prepared to act responsibly and in accordance with State law. Following are some general guidelines and more specific requirements to follow in case of an accident.


As a responsible driver, you must never leave the scene of an accident. Not only is it essential that you provide any necessary help immediately following an accident, but leaving an accident scene can result in having your driving privileges revoked or your license suspended.

After stopping your vehicle, you should pull up as close to the accident as safely possible, without obstructing traffic. Take a moment to assess the situation, and do not panic. Be aware of the traffic situation, and any other potential dangers, such as fire.

You should do your best to provide immediate assistance to other motorists, passengers or pedestrians that may have been injured in the accident.

Take extra care when attempting to move an injured person; if possible, wait for an ambulance to arrive. Notify 911 to report any injuries and call for medical assistance. Also inform the local New Hampshire police, sheriff or highway patrol.

If you have been injured in a car accident, it is important to stay calm. If possible, ensure that you are out of danger and not blocking any oncoming traffic. Call or wait for help, and do not attempt to move if you are unable to do so. See Auto Accident Injuries for more information.

  1. Name, address and contact details.
  2. Driver license number.
  3. License plate number of the vehicles involved.
  4. Auto insurance information for the motorists involved, if available.
