Ignition interlock in all cars would save $343 billion in 15 years
Installing alcohol ignition interlock devices in all new cars bought over a 15-year period would prevent 59,000 deaths and 1.25 million injuries, according to new research by the University of Michigan. In total, the devices would save $343 billion in 15 years. The cost of installing them would be recouped after just three years.
Researchers were surprised by the extent of their findings. Our analysis clearly demonstrates the significant public health benefit and societal cost savings associated with including alcohol ignition interlock devices as standard equipment in all new cars, said lead author Dr. Patrick Carter, assistant professor in the Department of Emergency Medicine at the U-M Medical School.
Nearly 35 percent of deaths and injuries that would be prevented would be among drivers ages 21 to 29. Drivers under 21 would also see a big drop in deaths and injuries. By applying such technology more broadly to all newly built vehicles, we can actually have a substantial injury prevention impact among traditionally hard-to-reach high-risk populations, Carter said.Download Bulletin PDF
