Do not volunteer any information about who was to blame for the accident. You may think you are in the wrong and then learn that the other driver is as much or more to blame than you are. You should first talk to your insurance agent, your lawyer or both. Anything you say to the police or the other driver can be used against you later.
Do not agree to pay for damages or sign any paper except a traffic ticket until you check with your lawyer. However, be sure to cooperate with the police officer investigating the case. But, stick to the facts. For instance, if you were driving 30 miles an hour, say so. Do not say, “I wasn’t speeding.”
