Bicycle-Related Injuries

Photo: Mom wearing a helmet helping daughter with bicycle helmetWhile only 1% of all trips taken in the U.S. are by bicycle,1 bicyclists face a higher risk of crash-related injury and deaths than occupants of motor vehicles do.2 In 2010 in the U.S., almost 800 bicyclists were killed and there were an estimated 515,000 emergency department visits due to bicycle-related injuries.3  Data from 2005 show fatal and non-fatal crash-related injuries to bicyclists resulted in lifetime medical costs and productivity losses of $5 billion.4

What are the major risk factors?

  • Adolescents (15-24 years) and adults aged 45 years and older have the highest bicycle death rates.3
  • Children (5-14 years), adolescents, and young adults (15-24 years) have the highest rates of nonfatal bicycle-related injuries, accounting for almost 60% of all bicycle-related injuries seen in U.S. emergency departments.3
  • Males are much more likely to be killed or injured on bicycles than are females.3
  • Most bicyclist deaths occur in urban areas and at non-intersection locations.5

How can bicycle-related injuries and deaths be prevented?

Effective interventions to reduce injuries and fatalities to bicyclists include the following:

  • Bicycle helmets: Bicycle helmets reduce the risk of head and brain injuries in the event of a crash.6 All bicyclists, regardless of age, can help protect themselves by wearing properly fitted bicycle helmets every time they ride.
  • Bicycle helmet laws for children: These laws are effective for increasing helmet use and reducing crash-related injuries and deaths among children.7

Interventions that have shown promise for reducing injuries and fatalities to bicyclists include the following:

  • Active lighting and rider visibility:
    • Fluorescent clothing can make bicyclists visible from further away than regular clothing during the daytime.
    • Retro-reflective clothing can make bicyclists more visible at night.7
    • Active lighting can include front white lights, rear red lights, or other lighting on the bicycle or bicyclist. This lighting may improve the visibility of bicyclists.7
  • Bicycle helmet laws for adults: These laws increase helmet use among adults.7
  • Roadway engineering measures: Information about roadway engineering measures, like bike lanes, that can improve safety for bicyclists is available from The Pedestrian and Bicycle Information Center.
