Abstract:
The danger of alcohol- and drug-impaired driving implies that policies that reduce substance abuse can save lives. Using several estimation approaches, we show that a US county’s supply of substance abuse treatment facilities is negatively and significantly related to the county’s number of motor vehicle deaths. We find that placing an additional treatment clinic in a county reduces the number of vehicle fatalities by 8%. An additional outpatient clinic, which specializes in treating the local population, can reduce the overall number of traffic deaths by 13% and the number of alcohol-related deaths by 24%.
