Random Breath Testing was introduced in Sweden in the seventies. The aim of the present study was to evaluate a Random Breath Testing campaign in parts of southern Sweden, which was started during the fall of 1992 and lasted less than a year. The RBT units were made highly visible, and these activities were accompanied by media coverage. Comparisons were made with a control area in southern and middle Sweden. A questionnaire was sent to 1500 randomly selected car owners in each of the two comparison areas on two occasions, before the start of the campaign and a year later. (A)
