Sammendrag

The project described in this report consists of the following parts: 1. Prevalence of drink-driving among drivers of heavy vehicles. 2. Accident risk related to drink-driving with heavy vehicles. 3. Possibilities of reducing drink- driving with heavy vehicles by alcolock, and 4. By increased enforcement. 5. Possibilities of implementation of alcolocks for heavy vehicles and for increased enforcement of drink- driving. 6.Cost-benefit ratios for alcolocks and enforcement of drink-driving for heavy vehicles. The project shows that the prevalence of drink-driving is very low, most likely between 0.005 and 0.25 per cent of all driving with such vehicles in Norway. The prevalence of drink-driving among drivers of heavy vehicles involved in fatal accidents is also very low, between 0 and 1.21 per cent. These low prevalences make it impossible to calculate accident risk. The possibilities of reducing drink-driving with heavy vehicles by enforcement and by alcolocks are discussed, and the cost-benefit ratio of these countermeasures is calculated.
