Bicycle helmets reduce the risk of severe injuries and fatalities and should be worn by all bicycle riders, and usage should not be determined by age, ability, or bicycle trip duration or purpose. A recent study on the safety effects of bicycle helmets suggests that wearing a helmet when bicycling is highly recommended. The use of bicycle helmets was found to reduce head injury by 48%, serious head injury by 60%, traumatic brain injury by 53%, and the total number of killed or seriously injured bicyclists by 34%.

Most bicycle and health advocacy organizations strongly encourage the use of bicycle helmets and recommend that helmets are properly fitted to the rider and meet the bicycle helmet standards of the U.S. Consumer Product Safety Commission, the American Society of Testing and Materials, or the Snell Memorial Foundation. Although there is no federal law in the United States requiring bicycling helmets, a number of states and localities have passed mandatory helmet requirement laws and these vary by age.
