If the accident causes traffic blockage, you or someone else should try to warn approaching vehicles about the accident. If available, use car lights or flashlights at night. If your vehicle is not driveable after the accident, you must have it removed from the scene. If the police officer makes arrangements for the tow truck, you should ask how much it will cost, tell the tow driver where you want your car taken, and ask for the tow driver's name, address and telephone number if you do not go with the tow driver. As soon as possible after the accident, report it to your insurance agent.
Most insurance policies require prompt reporting of accidents in order to guarantee coverage.
You can discuss the accident freely with your own insurance company and your attorney. However, it is inadvisable to give a statement about the accident to anyone representing the other driver, including the other driver's insurance company, without consulting your attorney. Under some circumstances you may be required to file a written accident report with the Missouri Department of Revenue, even if a police officer investigated the accident and made a police report. You should consult with an attorney to determine if it is necessary or advisable to file such a report in your situation. Do not voluntarily pay money to anyone in connection with the accident unless advised by your attorney that it is appropriate to do so.
