The roadside survey was conducted in two adjacent states in Germany. Data were collected from more than 21,000 drivers. Drivers were interviewed and a breath test and saliva sample obtained. Further, drivers were asked to provide an address where they could be contacted for an extended telephone interview. All alcohol-positive drivers and their matched controls were selected for the telephone interview. The purpose of the roadside interview was threefold: to obtain biographical data on the driver (e.g., age, sex, driving experience); to characterize the circumstances of the trip (e.g., destination, purpose, and presence of passengers); and to discover the driver's expertise concerning legal issues (e.g., knowledge about legal issues (eg knowledge about laws and sanctions). The telephone interview addressed drinking behavior, drinking and driving experience, and related topics. The authors found that about 5 percent of the trips involved a drinking driver, and were able to determine that certain subgroups are especially vulnerable to driving while intoxicated. (A)
