Commercial Driver Individual Differences Study (CDIDS)

The objective of this project was to identify the most critical driver characteristics, such as medical or work histories that increase crash risk. In the initial phase of the project, the feasibility of collecting exposure-based risk data for selected characteristics, as well as the feasibility of identifying commercial motor vehicle (CMV) driver factors that contribute to increased risk of large truck crashes, was explored. A follow-on pilot study was performed to determine the relative crash risk associated with driver characteristics, general health and wellness issues, medical conditions, drugs, and other driving performance characteristics. The next phase was a full-scale study that incorporated lessons learned from the pilot study. The objective of the case-control Commercial Driver Individual Differences Study (CDIDS) was to examine a wide array of driver and situational factors to determine their prevalence in and relationship to being involved in a crash. The CDIDS identified and prioritized commercial driver individual risk factors that primarily consist of personal factors such as demographic characteristics, medical conditions, personal attitudes, and behavioral history. These factors also include work environmental conditions, such as carrier operation type and compensation method. Risk factors were identified by linking the characteristics of individual drivers with their driving records through the duration of the study. Of particular importance was the occurrence or absence of critical incidents, including preventable crashes, crashes regardless of preventability, moving violations, and vehicle inspection violations. A final report that identifies individual factors that increase crash risk is under Agency review.
