With the background of growing concern about drinking and driving in Papua New Guinea, it was decided in 1990 to cm out roadside surveys similar to those that had been conducted in the UK and Australia. The work formed part of a program of co-operative road safety research between the Department of Transport and the Transport Research Laboratory, and involved close collaboration with the Port Moresby General Hospital, the University of Papua New Guinea, the Royal Papua New Guinea Constabulary and the Alcohol and Drugs Abuse Sub-Committee of the National Health Education Advisory Committee.
