There is some limited but growing research to indicate that drug-driving in New Zealand is an emerging road safety problem. The overall aim of the research was to provide a drug-driving demographic profile of New Zealanders and to make recommendations for possible countermeasures, based on the outcomes of telephone and internet surveys with the general population and face-to-face surveys with drug users. The drug-driving profiles of the general population and of specific drug user groups were assessed to understand the prevalence of drug-driving, driver behaviour, driver risks, risk exposure and potential countermeasures to deter drug-driving.
