Driving and alcohol
Norwegian legislation related to driving and alcohol is strict.
If someone has a blood alcohol level of more than 20 milligrams of alcohol per 100 millilitres of blood, he/she is deemed to be under the influence of alcohol for the purposes of the Road Traffic Act.
The regulations dealing with driving or attempting to drive while under the influence of alcohol or any other intoxicating or narcotic substance can be found in section 22 of the Road Traffic Act (cf. the links given in Chapter 19 above).
