Among children aged 1 to 14 years, crash injuries are the leading cause of death. The use of age-appropriate restraint systems can reduce this problem. Because all States have child restraint laws, more children now ride restrained. But loopholes in the laws exempt many children from coverage under either safety belt or child restraint use laws. Another problem is the persistence of incorrectly used child restraints and safety belts.
Motorcycles are less stable and less visible than cars, and they have high-performance capabilities.
When motorcycles crash, their riders lack the protection of an enclosed vehicle, so they are more likely to be injured or killed. The number of deaths on motorcycles per mile traveled is about 16 times the number of deaths in cars. Wearing a motorcycle helmet reduces the chances of dying in a motorcycle crash by 29 percent and reduces the chances of brain injury by 67 percent. An unhelmeted rider is 40 percent more likely to suffer a fatal head injury, compared with a helmeted rider. Graduated licensing is a system for phasing in on-road driving that allows beginners to obtain their initial experience under lower risk conditions.
