A nighttime roadside survey of rural Alberta drivers was conducted to quantify the nature and extent of impaired driving on Alberta's rural roads during nighttime. The survey also sought to describe driver demographics and information about the trip, such as origin and destination, among rural Alberta's nighttime drivers. Surveys were administered to drivers of vehicles that were randomly sampled at rural locations in Alberta between the hours of 10:00 PM and 4:00 AM between 22 August and 1 September 2001. Drivers who agreed to participate were asked a series of short questions. The interview concluded with the driver providing a breath sample to measure the driver's BAC level. Of the drivers surveyed, 3% had a BAC that was over the legal limit of 80 mg%. A total of 13% of drivers tested had detectable amounts of alcohol in their system.
