title: Reduction of the blood alcohol concentration limit in Norway--effects on knowledge, behavior and accidents.
abstract: From January 1, 2001, the legal blood alcohol concentration (BAC) limit in Norway was reduced from 0.5 to 0.2 g/l. A before-and-after telephone survey concerning the effects of the reduced BAC limit was carried out. 3001 driver's license holders were interviewed before and after the amendment. The percentage of drivers claiming that they will drink no alcohol before driving has increased from 82 to 91 percent, thus the distinction between driving a motor vehicle and drinking alcohol has become clearer. Drivers influenced by alcohol and involved in accidents have on the average much higher BACs than 0.5 g/l. Statistics on alcohol-related accidents are not available for the years before and after the legal amendment, but single-vehicle night-time and weekend personal-injury and fatal crashes are used as surrogate measures. There are no significant decreases in these proxies from the six years before to the six years after the reductions of the legal limit.
