Clinician guide to motorcycle helmet safety.

Motorcyclists' increased likelihood of involvement in motor vehicle collisions increases their risk of brain injury or death. Despite irrefutable evidence of the protective capabilities of motorcycle helmets, their use among riders is not ubiquitous. This paper is a functional guide to motorcycle helmet safety, assisting clinicians in promoting helmet use and treating patients with motorcycle-related injuries.
