LOS ANGELES POLICE DEPARTMENT: DRIVER IMPAIRMENT STUDY

The Los Angeles County Alcohol Safety Action Project, in conjunction with the L.A. Police Department, has conducted a three-phase experiment documenting the impairment of .10 percent blood alcohol concentrations on the driving ability of high tolerance drinking drivers. Phase I screened and selected a representative sample of drinking drivers and ranked them according to their tolerance to the intoxicating effects of alcohol on motorcoordination tasks. Subjects demonstrating a high tolerance to alcohol intoxication in Phase I, were included in Phase II which provided adequate familiarization and training on a validated driving course. In phase III, subjects were unknowingly divided into control and experimental groups with controls receiving 'placebo' alcoholic drinks. Driving scores were obtained on each subject on a pre (sober) and post (.10 percent BAC) basis, controls post-test scores were collect at .00 percent BAC. Analyses of the results indicates all drivers in the experimental group were impaired in their ability to drive. The average pre-post impairment was 22 percent.
