Reduction of BAC limit from 0.05 to 0.02 percent in Norway - effects on driver knowledge and behavior: some preliminary results

Terje Assum

It is a well established fact that the consumption of alcohol before driving a motor vehicle increases the accident risk. However, the importance of rather low blood alcohol concentrations (BAC) for accident risk is still under discussion. Norwegian studies find that drivers involved in fatal, alcohol-related accidents have on the average rather high BACs, above 0.1%. Some claim that "impairment occurs in most areas at the lowest BAC that can be reliably chemically determined". The question is thus: what effect will a reduction of the legal BAC limit from 0.05% to 0.02% have?

Maritime transport is a major source of emissions of harmful air pollutants and carbon dioxide. In a new project, a research team from the Swedish National Road and Transport Research Institute (VTI) and the University of Gothenburg has received SEK 6.4...


New research programme for more efficient travel

The Swedish National Road and Transport Research Institute (VTI) is playing an important role in a major new research programme to find radical solutions leading to fewer trips and more efficient travel, along with tools to enable better use of roads and...


Simulator used to practice emergency responses safely

Emergency responses of the police, ambulance, and rescue services are associated with a high risk of accidents, but practicing them in real traffic is neither safe nor permissible. A simulator-based method developed by the Swedish National Road and Transport...


Simulation of cut-in by manually driven vehicles in platooning scenarios

A study in a VTI-driving simulator has showed that a platoon will be able to handle a cut in from a manually driven car. The results of this study have recently been presented at two conferences in Japan.
