Make sure your car is properly road worthy.
All lights work, no jagged parts, tires with proper grip, insurance, tax, etc.. Whatever the rules are in your state.
Police probably want a chat to warn you about driving safe and to stop joyriding. If they wanted to charge you for a crime they probably would have turned up at your doorstep.
But you don't want to be pulled over for a chat only to be done over by a broken brake-light.
