Exposure to risk is a critical element in accident causation, yet only a limited amount of research has been conducted in an attempt to understand in detail the manner in which it operates. This study utilized comprehensive data that had been collected on over 14,000 California drivers in an earlier study, and subjected them to detailed analysis in an attempt to shed light on the role that exposure to risk plays in accident causation, with particular emphasis on qualitative aspects of exposure. A total of 33 variables were analyzed, including three personal variables (age, sex, marital status), four driving background variables (relating to driving experience and driver education), ten quantitative and qualitative exposure variables, and 16 driving record variables. The results conform the significant role that exposure to risk plays in determining accident and conviction experience, and further shows that: 1) of all the exposure variables studied, the quantitative measure of Average Annual Mileage is the best single predictor of driving record, and 2) the qualitative exposure variable of daytome-nighttime driving ratio is second only to quantitative exposure in being a useful predictor of driving record. Other qualitative variables also contribute significantly as predictors, but not to the same extent.
