Don't forget to buckle your seat belt.
Make sure you have your license, registration, proof of insurance, hope it's all up to date.
Make sure the vehicle doesn't have any tail lights out, the exhaust isn't too loud, and that the tints aren't too dark. License plates and registration stickers are clearly visible.
Make sure that you don't speed, follow too closely, or drink any beer.
It's not as though when you choose to drive you are suddenly free from the long, long, long arm of government regulation.
