Mandated server training and reduced alcohol-involved traffic crashes: a time series analysis of the Oregon...

This paper reports the results from an evaluation of the first statewide mandated training for alcohol servers. The state of Oregon introduced training for all alcohol servers (and for one year all owners/managers) beginning in December 1986. Servers must complete training once over a five-year cycle; by December 1989, over 50% of servers and managers had been trained. We found statistically significant reductions in single-vehicle nighttime traffic crashes (those with high percentage of alcohol involvement) by the end of 1989 following the implementation of the compulsory server-training policy.
