Traffic safety plays an important role for individuals of any age. For children, bicycle and pedestrian safety are fundamental in decreasing childhood injuries and fatalities. Studies show that most traffic safety injuries can be prevented through education and enforcement. The risk of permanent or fatal head injuries can be reduced by 87% simply by wearing a bicycle helmet. In addition, under California law anyone under 18 years of age can be cited for riding a bicycle, scooter, skateboard, or roller skates without wearing a properly fitted helmet.
