You may wish to contact a personal injury attorney immediately. He may wish to examine the evidence at the site and gather as much information as possible.

Contact your own insurance company as quickly as possible. If you feel that, for any reason, your company may not be willing to cover the accident, you should consider contacting a personal injury attorney first. However, do not delay in contacting your insurance carrier. Most insurance companies have requirements in the policy as to how quickly you must contact them, and failure to do so might mean your claim will be rejected. On the other hand, you should not answer any questions or make any statements to the other drivers' insurance companies until you have consulted an attorney. Be polite, but decline to discuss any aspects of the accident until you have obtained legal advice.

If you have been seriously injured, you will probably be taken directly to a hospital emergency room. If you are not seriously injured, however, do not assume that you are uninjured. Many injuries from vehicle crashes, like whiplash, do not show up right away. If you do begin to suffer ill effects from the crash, notify your health professional immediately, get yourself checked out, and follow the doctor's instructions as to care and follow-up. Failure to get medical care might have serious consequences if you have latent injuries that only show up 24-36 hours later. Do not neglect symptoms that are unfamiliar, or pain that appears hours later. Report any symptoms to your doctor, however slight. Serious back injuries can start out as nothing more than an aching back, but left untreated they can cause major health difficulties. Furthermore, if you do have problems your insurance company will need proof that the problems were diagnosed and treated promptly, and that the problems were related to the accident.

If you can get a camera, it is wise to take as many photos as possible of the accident site, the vehicles, and people involved, and any thing else that might have bearing on how and why the accident occurred. Pictures taken as soon as possible will be the most valuable. If you do not have a camera, you might be able to buy a disposable one at a nearby convenience store, or ask a passenger or bystander to purchase one for you. Don't forget to take pictures of the damage done to all vehicles, license plates, evidence such as street signs or lights, skid marks, etc. If you have an attorney you plan to call, tell him you don't have a camera. He may be able to send someone from his office to take the needed photographs. Be sure to also tell your attorney about any other evidence you think might be important, such as faulty street lights or signage, malfunctioning equipment (seat belts, turn signals, etc.), weather conditions, etc.
