Summary
This 2005 report by the National Highway Traffic Safety Administration (NHTSA) addresses the under-researched issue of driver distraction in commercial trucking. While prior studies focused on passenger vehicles, this study investigates whether in-vehicle technologies pose similar or distinct risks for truck drivers, who operate complex vehicles with different cognitive and physical demands. The research aims to characterize the extent of the distraction problem, analyze specific device interfaces, and identify industry practices to inform future safety guidelines. The study employed a mixed-methods approach involving three primary tasks. First, researchers conducted interviews and a focus group with 32 truck drivers and 12 safety/regulatory personnel to assess perceptions of distraction and device usage. Second, they performed an inventory and analytical assessment of commercially available in-vehicle devices, evaluating their interface designs against human factors guidelines. Third, they interviewed Original Equipment Manufacturers (OEMs) and suppliers to document industry design and evaluation practices. The driver sample consisted primarily of long-haul fleet drivers with significant experience, while regulatory contacts were drawn from state agencies and the Commercial Vehicle Safety Alliance. Key findings indicate that while 64–65% of respondents viewed distraction as a problem for truck drivers, it was not considered a high-priority issue compared to fatigue or logistical pressures. Many participants believed truck drivers were less susceptible to distraction due to their professionalism and experience. However, 48% of interviewed drivers reported experiencing a "close call" while using devices, such as drifting out of lanes while texting or searching for equipment. The device inventory revealed widespread availability of multi-functional systems, particularly text messaging units like Qualcomm. Although many devices included "lock-out" features to restrict use while driving, these were not uniformly implemented by fleets. Furthermore, industry evaluation practices varied significantly; while some OEMs used objective workload models and secondary task testing, others relied primarily on market research and user feedback, often treating specific safety evaluation methods as proprietary. The report concludes that while truck drivers perceive themselves as capable of managing distraction, objective data suggests significant risk, particularly with text-based communication systems. The lack of standardized evaluation practices and the inconsistent application of safety restrictions highlight a need for further research. The authors recommend analyzing crash databases to quantify distraction-related incidents, conducting naturalistic studies to measure performance degradation, and convening industry panels to establish uniform criteria for assessing the safety of in-vehicle technologies. This work serves as a foundational step toward developing specific guidelines to limit unsafe distractions in the commercial vehicle sector.
Key finding
Nearly half of the interviewed truck drivers reported experiencing close calls while using in-vehicle devices, highlighting a safety risk despite the general perception among drivers and regulators that distraction is not a high-priority issue.
