Most drivers in Knoxville make at least one costly mistake after an accident. Here’s how to avoid it. After an accident, of course, you should check on yourself, everybody in your car. You should call the police, exchange information with the other driver, and also take photographs. One of the biggest mistakes people make is by not contacting an attorney immediately. They may think they can handle it on their own with the insurance company and then they get into a back and forth where all of the sudden they may have even resolved their case and they don’t even know it. You should contact a lawyer from day one so that we can get on your case and help you out.
