Identifying alcohol-impaired drivers

In: UMTRI Research Review, Vol. 16, No. 5, March-April 1986, p. 1-11

Authors: Paul L. Olson

The state of the art of police measurement of driver impairment was reviewed in a project and reported in 'Measurement of Blood Aldohol Concentration in Michigan Drivers: A Review of the Literature (UMTRI-85-52).' The project assessed 2 methods of screening stopped drivers: a set of physical tests, and portable breath-testing instruments. Findings from the study are discussed in this article. Studies are discussed that investigated the extent to which alcohol in the blood causes impaired driving, the probability of arrest, field sobriety tests, and portable breath-testing devices.
