Samenvatting
The results of two national surveys are described which were designed to assess the effect of the new drinking and driving law and the publicity campaign. After the new law had come into force, drivers drank away from home as they did before but were less likely to drive back after drinking. Among drivers, there is an increase in knowledge about the new law and what it means for them: and few disapprove of the police powers. However, most drivers think they know how much drink it is safe to take before they reach the limit and the extent to which they are tolerant of drinking and driving seem not to have changed since before the campaigns.
