Drug use while driving poses a serious risk to road safety. Impaired drivers have slower reaction times, reduced coordination, and impaired judgment, increasing the likelihood of crashes. Roadside drug testing is a key enforcement strategy used across Australia to detect and deter drug-impaired driving and to support broader efforts in reducing traffic-related harm.
