This aim of the research was to examine the prevalence and characteristics of illicit drug related driving in WA through the analysis of the records of drivers and riders fatally injured between 2000-2012 and drivers and riders charged with a Section 64AC offence (illicit substance in oral fluid), 2008-2012. The aim of the research was to give a snap shot on the enforcement of illicit drug driving.  
The research found:

  • Approximately 23% of fatally injured drivers/riders tested positive to one or more illicit substances with the annual rate of detection unchanged for the full study period, with some preliminary evidence of a decline from 2008. The odds of testing positive were significantly higher for: males; those aged under 40 years; those driving without a valid licence; those testing positive to alcohol in the range 0.05gm%-0.149gm%, and those using benzodiazepines with and without opioids.
  • Around 4% of drivers and riders undertaking a roadside oral fluid test 2008-2012 were charged with a Section 64AC offence. The annual offence rate significantly increased over the period. Offending was highest for males, younger age drivers/riders, and in the metropolitan area and select metropolitan police districts.
