Abstract Using samples of blood obtained from 497 injured drivers at a Rochester, NY
hospital, this study determined the incidence rates of alcohol, THC (marijuana agent),
and other drugs. Accident data (police reports, driver interviews) were also collect­
ed, and analyses determined driver culpability rates, collision types, and crash cir­
cumstances involving alcohol and certain drugs. Main substances found were alcohol.
(25%), THC (10%) and tranquilizers (8%); 38% of the drivers had alcohol or some other
drug tested for in their systems. Culpability rates were: 74% for intoxicated drivers,
53% for THC-only drivers, 34% for drugfree drivers, and 22% for tranquilizer-only,
drivers. Alcohol-involved crashes were predominantly single vehicle accidents, followed
by striking vehicles in head-on and rearend impacts. No unique THC or tranquilizer
collision types were found. Circumstances overrepresented in alcohol crashes were
curves, occurrence on weekends, occurrence between midnight-6AM, unlighted streets, and
non-intersection locations. "Alcohol accident types" were identified, e.g. single-
driver crash occurring midnight-6AM on a curve (95% alcohol involvement). Police report
ing of alcohol involvement was also analyzed. Possible roadway and vehicle counter­
measures to reduce impaired-driver accidents were suggested. Other recommendations
addressed police alcohol detection and NASS or FARS monitoring of alcohol involvement.
Further study clarifying the crash roles of THC and tranquilizers in fatal and non-fatal
crashes was considered essential.
