The most important thing to have to be safe in a car is a safe car. Cars like Volvo and Chrysler are very strong and reduces the chances of injuries in an accident.
Always use your seat belt. Don't unhook it until the car has parked. Wear your seat belt even if you're just riding the car for ten meters.
Sit as far away from the air bag as you can. If you sit too close the air bag will blast your face and kill you.
If you weigh below eighty pounds-even if you are an adult-use a booster seat. If you are using a booster seat, always sit at the back of the car.
Children under the age of twelve-even if they're adult size-always have to sit in the back of the car.
Don't put one hand on the steering wheel and the other on a cell phone or cigarette. You might not have enough time to steer and if that happens then you will crash.
If you're a passenger, don't stick you hand or head out of the windows. If a car passes then your hand or head might get sliced off. You might also get hurt by power windows when they rise up. This applies to children too.
Jeeps and trucks are always safer than cars because they are big, heavy and strong. Buy one if you can afford it.
Avoid driving in the snow. You will likely slide and crash. If a snowy day comes up, ride a bus instead of driving a car.
Well I hope you will follow these rules. Stay safe and have fun driving.
