Do not speed up to try to make it through the intersection when the signal turns yellow. Teenagers have many more car crashes than older persons. Place limits on the amount of unsupervised driving you allow a teen. Driving faster than the speed limit makes it more difficult to react and as results in greater impact should there be a crash. If you are tired, pull off of the road to a safe spot and take a nap, or trade drivers.
Many accidents occur due to driver fatigue.
Keep your trunk well stocked with a flashlight, flares, a spare tire, a jack and a first aid kit. In case you break down, keep a spare blanket, a gallon of water, and some granola bars stowed, as well. Other safety practices include proper maintenance of the car. Keep the tires in good condition and properly inflated. Make sure that you have a professional check the brakes at least twice a year, or whenever they squeak or the car pulls to one side when you are braking.
