Abstract: Alcohol-related fatal crashes are a costly public safety concern. Using vehicular fatality data and geographical variations across the USA, I examine the effectiveness of mandatory Ignition Interlock Programs for first time offenders in preventing fatal alcohol-related accidents. I observe that the program is most effective when it is applied to a broader cross-section of first time offenders. Specifically, states that adopt ignition interlock laws that require participation of first time offenders, with blood alcohol levels of .08 or higher, see fatal accidents involving a drunk driver decrease by 9%. The results provide evidence in support of current and future policy legislation that first time offenders should participate in ignition interlock programs, which will reduce alcohol-related fatal accidents and generate large benefits to society.
