Impact of Helmet Law Repeal on Motorcycle Crash Incidents Attended by EMS in Missouri

Impact of Helmet Law Repeal on Motorcycle Crash Incidents Attended by EMS in Missouri

Previous research has shown motorcycle helmets save lives, reduce serious injuries, and reduce costs associated with healthcare, lost productivity, and other economic costs.1-3 The state of Missouri repealed its universal helmet use law for motorcyclists aged 26 and older with valid health insurance on August 28, 2020. The aim of this study was to compare characteristics of motorcycle crashes (MCC) attended by emergency medical services (EMS) in Missouri before and after the repeal of the helmet use law.
