In most states if you get pulled over with an expired drivers license you'll get arrested and booked into jail where you'll have to pay a bond to get out.
If there's no one else with you that has a drivers license to drive the car or other vehicle then the vehicle will likely be towed and put in impound and you'll have to pay the towing and impound fees to get it out.
Never drive with an expired drivers license as it can give you a lot of problems and be costly for you.
