This workshop examined the apparently narrow and well-defined topic of police detection of alcohol and other drugs among drivers of private motor vehicles. The workshop appeared to be limited to impaired driving enforcement: How police identify drivers who may be impaired, and how they determine whether drivers are under the influence of alcohol and other drugs. But workshop participants quickly came to appreciate that these enforcement issues were intertwined with the entire system of impaired driving laws, enforcement, and sanctions. Consequently, the workshop papers, discussions, and ideas had a broad range. This paper summarizes some key points made at the workshop. It concentrates on the workshop's goals. How can police detection be improved? What changes in legislation and programs make any difference? This paper attempts to capture the sense of workshop participants as expressed in their papers and discussions. Throughout this paper, the term "impaired drivers" refers to drivers impaired by alcohol or other drugs. "Alcohol-positive" refers to drivers with a measurable amount of any drug that can impair driving performance. "Police" refers to any law enforcement officer with the authority to enforce impaired driving laws.
