If you are found guilty of leaving the scene of an accident, is that a misdemeanor or a felony?

This depends on your particualr state law. In Michigan, leaving the scene of the accident where there has been no injury or death is a Misdemeanor. If there was an injury or death, the charge can be increased to a felony. Not certain if you have been found guilty or not, but I would advise you to speak with a criminal defense attorney in your area for more specifics based on the facts of what happened.
