;The wintertime accident risks of drivers and the factors affecting the risks were analyzed using statistical accident models. The evaluation method was based on reliability theory and on survival modeling. The data consisted of two parts: responses to a postal questionnaire, addressed to 10,000 vehicle owners, about driving and accidents during wintertime in the years 1991-1993; and detailed records of fatal accidents, in the years 1987-1991, generated by in-depth accident investigation teams and compiled by the Motor Insurers' Road Safety Committee (VALT). Replies to the postal questionnaires were received from 5,881 vehicle owners, giving a response rate of 59%. The replies included 296 self-reported accident involved drivers. The VALT data on fatal wintertime accidents contained 658 drivers involved in fatal accidents. The analyses of the two data sources confirmed that driving conditions and kilometreage driven during the wintertime contribute to amount of accidents. The best explaining variables in both survival and risk models of wintertime driving were driver characteristics (age, driver behavior, kilometreage driven, speed, and use of safety-belt), drivers' state (driving under the influence of alcohol) and vehicle characteristics (vehicle weight and condition of tyres).
