There are a few exceptions to the general rule that drivers must have vehicle insurance. In some states, drivers who are able to post a bond or cash deposit equal to the amount of insurance coverage required may be able to drive without insurance. In other states, drivers who have a valid driver's license from a foreign country may be able to drive without insurance for a certain period of time.
If you are caught driving without insurance in a state where it is required, you may be subject to fines, penalties, and other consequences. These can include having your driver's license suspended or revoked, your vehicle impounded, and being ordered to pay restitution to victims of accidents.
