If you are involved in an auto accident or stopped by a police officer and found to be driving without car insurance or proof of financial responsibility, you will be subject to penalties specific to the laws of your state. For violation of the financial responsibility law, those penalties could include a fine or loss of driving privileges. If you are uninsured and in an accident that involves property damage or injuries to people, you will be required to pay out of-pocket for any damages assessed by a court.
