After an injury, make sure that you are in a safe place, away from additional danger. Summon emergency responders if necessary. Remember that you may be in shock, so your injuries may be more serious than you realize. If you are injured in a car accident, report the accident to law enforcement. If it occurs at a business or somewhere other than your home, let the property owner know.
Take photos. Save things related to the accident like clothing you were wearing. Get contact information for witnesses, if possible. Don’t admit fault or apologize.
