First, call the police. You are required to do so in New Hampshire if you’re involved in a serious car accident. Just call 911 and wait for an officer from the nearest local police department or New Hampshire State Police. If you are injured or anyone else appears hurt, ask the police dispatcher to send an ambulance. If you are healthy enough, start gathering evidence at the scene of your crash as well. Take pictures of your accident. Get the names and phone numbers of witnesses. Exchange information with the other driver. Then call a New Hampshire car accident lawyer. An experienced attorney can help you every step of the way after your collision.
