Yes, if your injuries are serious and require immediate medical attention. It does not matter how minor you think your injuries are, as you are not a medical expert in most cases. It is best to call an ambulance and get checked out at the scene of the accident. However, calling an ambulance right after an accident may not always be necessary, and choosing not to do so does not automatically hurt your case. Many accident injuries turn out to be serious even though an ambulance was never called to the scene. An experienced car accident attorney can help you understand how your medical treatment and other evidence may affect your injury claim.
