Samenvatting
During the interval 1 December 1983 to 11 January 1984 the Ministry of Transport conducted a traffic enforcement- publicity campaign known as "operation checkpoint". Squads of traffic officers were deployed during the main drinking hours (20:00 to 02:00) in the vicinities of licensed drinking premises, their object being to stop and check (for sobriety) drivers of cars coming from such premises. The proportion of injury accidents in "Main Drinking Hours" relative to all reported injury accidents decreased significantly, as did the proportion of accident compensation corporation traffic injury claims which resulted from incidents that occurred during the "Main Drinking Hours".
