Abstract
Drink driving is widely recognised as a major road safety problem. In Australia, the maximum allowed blood alcohol concentration (BAC) is 0.05. Despite the enforcement of this limit through random breath testing, during the inclusive period 2006-2010, 19,413 crashes involved a drinking driver/rider. Of these crashes, 8.3% resulted in one or more fatalities, and 44.9% resulted in serious injuries. Health promotion messages in Australia encourage the monitoring of the number of standard drinks consumed prior to driving. As such, restaurant patrons may believe they will remain under the legal limit and therefore they may drive to the venue, and drive home, whilst intoxicated. Therefore the research aimed to investigate the commuting behaviour and BAC of diners at Sunshine Coast restaurants.
