Immediately after a car accident, your first priority should be safety. Check for injuries and move to a safe location if possible. Once safe, call 911 to report the accident and request medical assistance. Even if injuries seem minor, a medical evaluation is crucial, as some injuries might not manifest immediately. Gather as much evidence as possible from the scene by taking photos and exchanging contact and insurance information with other parties involved. Filing a police report is essential and can support your claim later.
