Summary
This report addresses the low adoption of safety belts among Commercial Motor Vehicle (CMV) drivers, a critical safety issue given that less than half of CMV drivers used belts compared to 79% of passenger car drivers. In 2002, over half of the 588 CMV drivers killed in crashes were unbelted, and 80% of ejected drivers were not wearing belts. To support the Federal Motor Carrier Safety Administration’s (FMCSA) goal of reducing fatal truck-involved crashes, the Center for Applied Research, Inc. (CFAR) conducted a study to identify motivational factors, ergonomic barriers, and best practices influencing safety belt usage. The research aimed to inform the Commercial Motor Vehicle Safety Belt Partnership’s outreach efforts. The study employed a mixed-methods approach, including a comprehensive literature review of safety research in the U.S., Australia, and the United Kingdom, as well as ergonomic assessments of truck designs. Primary data were collected through parallel surveys of 120 fleet managers and structured interviews with 238 CMV drivers at truck stops in Georgia and Wisconsin. Additionally, the research team consulted with truck manufacturers and industry associations to evaluate technological approaches and management practices. The fleet manager survey assessed policies and enforcement methods, while the driver survey focused on individual attitudes, behaviors, and specific complaints regarding belt functionality and comfort. Findings revealed distinct barriers to usage. Fleet managers identified the primary reasons for non-use as the effort required, forgetfulness, habit, poor fit, discomfort, restricted movement, and a belief that belts do not increase safety. The most effective promotion methods cited by managers were rewards for observed use, direct observation, and punishments for non-use. Drivers reported wearing belts primarily for safety, legal compliance, or habit, while non-users cited comfort and personal choice as main deterrents. Approximately 62% of drivers complained about belt issues, specifically citing rubbing against the neck or shoulder, locking mechanisms, tightness, and limited range of motion. Ergonomic assessments confirmed that while newer belts were more user-friendly, they remained uncomfortable for drivers with large or small statures, and many drivers were unaware of existing features designed to improve comfort. The study concludes that increasing safety belt usage requires addressing both motivational and ergonomic factors. Recommendations include improving belt design to accommodate diverse driver statures and enhancing driver awareness of comfort features. The findings provide a baseline for the FMCSA and industry partners to develop targeted outreach programs, emphasizing that current regulatory frameworks and fleet management practices often lack consistent incentives or penalties to enforce usage. By understanding these specific barriers, stakeholders can implement more effective strategies to improve driver safety and reduce crash severity.
