What do I do?

If you let someone use your car and that person caused an accident and that person was drunk, then you may be liable for the damages for "negligent entrustment" of your motor vehicle to someone you knew or should have know was not then competent to be behind the wheel. If you own a car and do not have insurance on that car and if that car is involved in an accident, then you can lose your license for violating Ohio's financial responsibility laws. You can lose you licence until the damages are paid. If someone who caused an accident used your name, then that person likely had your ID on them at the time. The bottom line is that you are in a really rotten situation and you need to hire an attorney to try to get the mess resolved.
