In a previous study examining occupational vs. nonoccupational fatal motor vehicle collisions (MVCs) in Kentucky, the percentage of fatal occupational MVCs involving driver fatigue and/or driver distraction and inattention was increased relative to fatal non- occupational MVCs (15% vs. 3% for driver fatigue and 25% vs. 13% for driver inattention/ distraction). This study was undertaken to determine if driver fatigue and inattention may be increased risk factors for fatal commercial vehicle collisions (CVCs) when compared to nonfatal CVCs in Kentucky. Case and control data were obtained from the Kentucky Collision Report Analysis for Safer Highways (CRASH) electronic files for 1998-2001 from the Kentucky State Police Records section. CVCs were selected from all 560,497 MVCs. Cases (n= 51) were drivers who died (fatal) and controls (n= 31,629) were drivers who survived (nonfatal) a CVC. Cases were matched to Fatality Assessment and Control Evaluation (FACE) cases to confirm working status at time of death. Selection variables for cases and controls included vehicle type, position in vehicle, and injury classification. In descriptive analyses, driver distraction/inattention (31 % cases vs. 26% controls), fatigue (10% cases vs. 1 % controls), and the vehicle not under proper control (10% cases vs. 2% controls) were factors more frequently involved in fatal CVCs compared to nonfatal CVCs. Additionally, more deceased CVC drivers were not using their seatbelts (47% cases vs. 6% controls), were trapped (55% cases vs. 1 % controls) and were totally ejected (24% cases vs. 0% controls) from their vehicles compared to drivers who survived a CVC. These data suggest that driver distraction/inattention and fatigue as well as other collision factors may be increased risk factors for a fatal CVC. Multivariate analyses including calculation of odds ratios will be performed on these data to measure the effect of these variables alone or combined on fatal vs nonfatal CVCs.
