DON'T assume that other cars know what you are doing, either. Make sure that you use your turn signals and give yourself, and the cars around you, plenty of room to maneuver.

DON'T tailgate other cars, pass on shoulders, fail to yield, run stoplights or stop signs (even if no one else seems to be around), or break any other rules of the road on purpose. If you act like you are above the law when you operate a car, you will sooner, rather than later, find out that you are not.

DON'T play your car stereo so loudly that you are disruptive to others, or so loudly that you are unable to hear train signals or emergency vehicle sirens.

DON'T talk on your cell phone and drive at the same time. If you need to make or answer a telephone call while you are driving, pull over at a safe place, use the phone, and then resume your journey.

DON'T engage in other activities, while driving, that distract your attention or reduce your reaction time. Eating, changing clothes, or putting on makeup while driving is dangerous. In some states, if you are caught doing these things while driving you can be cited for "driver inattention" and given a ticket.

DON'T treat a car like it is a toy. It is not. Don't use your car to play chicken, race, or give another car a friendly "tap."

DON'T let your emotions and frustrations get the best of you. Don't engage in road rage, no matter how irritating another driver might be to you.

DON'T leave valuables in your car, especially in places where they can be seen, no matter where you are parked.
