In 1991, the NHMRC Road Accident Research Unit conducted a roadside breath alcohol survey of night-time Adelaide drivers. In the middle of the survey, the 1991 Australian Formula I Grand Prix was held and licensed premises were permitted to open 24 hours a day. Sampling of drivers continued during the Grand Prix when a total of 509 breath tests were obtained. These tests were then compared with a matched sample of 2621 drivers tested before and after the Grand Prix. It was found that late night drivers' blood alcohol levels were significantly elevated during the time of the Grand Prix. (A)
