AN INSTANCE OF EFFECTIVE LEGAL REGULATION: MOTORCYCLIST HELMET AND DAYTIME HEADLAMPS

This study was undertaken to measure the impact of helmet use laws and daytime headlamp use laws in terms of compliance with the laws and of effects on fatalities. It also illustrates alternative statistical models for use in quasi-experimental research designs. The data on observed motorcyclists in this study indicate that, some years after the laws went into force, states with motorcyclist helmet use laws and daytime headlamp use laws have substantially higher use of both than states without such laws. States with helmet use laws had, on the average, decreases in motorcycle involved fatalities in the year of and the year subsequent to the enactments of these laws compared to matched states that had extremely limited or no such laws during the same periods.
