Before you do anything, such as calling your insurance agent, you need to be examined by a medical professional. Even if you feel okay, it is better to be safe than sorry. Some injuries don’t present right away, leading you to believe you are fine.
At some point, once you are able to do so, you will contact your car insurance agent. This person is available to help. This person should be on your side. Even so, you don’t want to go into the conversation with any preconceived notions.
