New Visual Abstract Available: Modeling the Impact of Alcohol Ignition Interlock Systems


Modeling the Injury Prevention Impact of Mandatory Alcohol Ignition Interlock Installation in All New US Vehicles

The University of Michigan Injury Prevention Center is excited to offer a new visual abstract of a study by core faculty Director Patrick Carter, Core Faculty Dr. Carol Flannagan, Senior Advisor Dr. Rebecca Cunningham, and Dr. Jonathan Rupp.

Published in 2015 in The American Journal of Public Health, the study focused on the injury prevention impact and cost savings associated with alcohol interlock installation in all new U.S. vehicles. Findings showed that these types of interlocks to address drinking drivers would prevent approximately 85% of alcohol-involved crash fatalities (>59,000) and between 84% and 88% of nonfatal alcohol-related crash injuries (1.25 M) over 15 years. The authors concluded that alcohol interlock installation in all new vehicles is likely a cost-effective primary prevention policy that will substantially reduce alcohol-involved crash fatalities and injuries, especially among young vulnerable drivers.
