A: The answer depends on a number of factors. The best answer is to contact an automobile accident attorney immediately. For example, if your case is against a governmental entity (hit by a police officer, a city vehicle, certain ambulances, etc.), the deadline can be as little as one year. It is often very difficult to know if your case is against a governmental entity, however, so do not delay. For example, if an employee of certain county hospitals was on a trip to deliver test results to a physician when he hit you, the deadline would be one year. However, you might not know that the employee was on the job since he was in his own vehicle. Most cases must be filed within two years. But again, the best answer is to contact an automobile accident lawyer immediately. Don't wait! If you do, it could be too late.
