Stay at the scene, call 911, and wait for law enforcement to arrive. An officer from the Newark Police or the New Jersey State Police will secure the area and conduct an initial investigation. Cooperate with the police and share contact and insurance information with the other driver, but keep your comments brief. Stick to the facts, don't talk about fault, and don't apologize. Anything you say could potentially be used against you by an insurance company.
Your next step should be to get medical attention. Go to the emergency department at a local hospital like St. Michael's or Newark Beth Israel Medical Center, an urgent care clinic, or your own doctor if they have same-day appointments. This is important to protect your health, even if you feel fine – you may have a delayed-onset injury like a concussion or internal injury. It also creates a record of your injuries.
Then, call a verified Newark car accident lawyer from this directory. The sooner you get legal representation, the better.
