This report describes the results and conclusions of Assessment of Driver Safety in Commercial Motor Vehicles, a Safety IDEA project aimed at providing further validation of WayPoint (WP), a 4-minute, non-verbal, web-based assessment of a truck driver's propensity for having preventable collisions. Key applications of the WP assessment are: (a) to select safer driver/applicants; (b) to determine who among existing drivers would benefit most from training; (c) to diagnose which issues should be emphasized in training. A total of 1,218 truck drivers from seven different fleet operators completed WP as part of this project. Criterion measures were collected from each of the companies and included, at a minimum tenure with the company and number of preventable (at fault) and non-preventable collisions. The primary criterion measure was based on a driver's preventable crash frequency adjusted for exposure and expressed as an odds ratio, i.e. a driver's crash frequency/average crash frequency in the population of all drivers in the data base. An odds ratio of 1.0, for example, indicates that a driver's crash rate is average among all drivers; 3.0, three times the average, and so on. Four levels of a Poisson-distributed odds ratio were discernable: (a) 0.5, half of all drivers, (b) 1.2, 35% of all drivers, (c) 3.4, 11% of the drivers, and (d) 6.2, 4% of the drivers. In 79 cases, we were provided with a record of complaints from the driving public and the cost of each preventable crash.
