Analysis of motorcycle crashes in Michigan 2009-2013

Abstract

The goal of this analysis is to assess the consequences of the modification to the motorcycle helmet law that took effect on April 13, 2012, based on crash data from 2009-2013. The key areas of interest include: 1) changes in fatality and injury rates due to helmet non-use; 2) helmet use rates among crash-involved riders, especially those under 21; 3) out-of-state ridership, as it is seen in the crash data; 4) risk-taking behavior such as alcohol use and recklessness, as it relates to injury and fatality outcomes; and 5) motorcycle endorsements among crash-involved ridersMichigan State Police Office of Highway Safety Planninghttp://deepblue.lib.umich.edu/bitstream/2027.42/109726/1/103142.pd
