They account for almost 50,000 deaths and 4 million to 5 million injuries every year.
Older drivers are at the greatest risk.
Older drivers have a higher accident rate per mile driven and are more likely to be killed or injured in an accident than younger drivers. Most collisions occur because of human error rather than mechanical failure of the car. Maintain the recommended tire pressure and replace worn tires. Check your brakes and lights regularly. Always wear the lap belt as well as the shoulder belt.
