Trends in hotel patronage and drink driving in Hobart, Tasmania

From 1990 to 1991 in the Hobart region there was a marked fall in both hotel patronage and the proportion of patrons subsequently driving with their blood alcohol concentration above the legal limit, This was associated with smaller falls in the number of drink drivers charged and alcohol-related road accidents, which continued in the following year. It appears that the pattern of drinking and driving is changing, presumably in response to random breath testing and tougher penalties for offences.
