A meta-analysis of bicycle helmet efficacy by Attewell, Glase, and McFadden (2001) estimated that bicycle helmets reduce the risk of head injury by 60% and brain injury by 58%. As of March 2022, 22 states, the District of Columbia, and more than 201 localities had bicycle helmet-use laws, according to the Bicycle Helmet Safety Institute.
