A questionnaire was sent to 20 000 passenger car owners randomly selected among the policy-holders in Gjensidige Insurance company, and owners of all the passenger cars (about 17 000) insured in the same company involved in traffic accidents during the winter 1994/95.
A case-control study was performed, and we tried to control for factors which are correlated with both the choice of winter tires and the accident risk.
