The legislation, which became effective in Victoria on May 22, 1984, makes it an offense for the following driver categories to drive any motor vehicle while having a BAC above .00g/100ml: drivers with learner permits, drivers with first year probationary licenses, unlicensed drivers, and disqualified drivers. The law's introduction was accompanied by a large-scale publicity/education campaign to ensure that the targeted driver categories were aware of the new legislation and associated penalty severity. The campaign included advertising on television, radio, and in the press as well as community service announcements. The market survey was conducted in December 1984 and involved a sample of 309 males and females aged 16 and over in metropolitan and country areas of Victoria. Public awareness of the law was found to be high. 9 tables, 7 references.
