TØI has evaluated the Norwegian system for driver license demerit points. Analyses of the demerit point register show that drivers who are at risk of license revocation due to a high number of demerit points reduce their risk of further traffic violations. In 2011 the system was changed to the effect that drivers with a probationary license (first two years after licensing test) incur twice as many demerit points for each violation, compared to full-license drivers. This is a possible explanation of the finding that novice drivers have reduced their crash risk more than the general driving population. A questionnaire study confirms the analyses of register data, showing that drivers with many demerit points report to have changed their driving behaviour most positively as a consequence of the demerit point system in general as well as the fact that they have incurred demerit points.
