Summary
This study investigates the relationship between the scarcity of rest areas and fatigue-related crashes among long-haul truck drivers (LHTDs) in Saskatchewan, Canada. Motivated by the high prevalence of driver fatigue and the lack of data regarding the specific locations of fatigue-related incidents, the research aimed to map crash patterns and gather driver feedback on mitigation strategies. The authors sought to identify optimal locations for new infrastructure to reduce crash risks. The researchers employed a mixed-methods approach. Quantitatively, they analyzed de-identified data from Saskatchewan Government Insurance databases covering 2007–2017, linking driver demographics, crash reports, and medical conditions for Class 1 license holders. They mapped 201 fatigue-related crashes (caused by extreme fatigue or falling asleep) against highway characteristics and existing rest area locations. Qualitatively, they conducted semi-structured interviews with 67 LHTDs recruited from truck stops in Alberta and Saskatchewan. These interviews were analyzed using thematic analysis to assess perceptions of fatigue, access to rest areas, and recommendations for improvement. The results indicated an average of 20 fatigue-related crashes per year. Statistical analysis revealed that drivers involved in fatigue-related crashes were significantly younger (mean age ~38 years) and had less experience (mean ~6–7 years) than those who crashed while awake. Crash concentrations were highest in major cities like Saskatoon and Regina, as well as along major highways. Highway length was significantly associated with crash frequency, particularly on two-lane highways. Qualitative findings highlighted a severe shortage of adequate parking; 91% of participants reported insufficient rest areas, and 96% cited lack of parking as a primary concern. Drivers reported being forced to drive while fatigued or park in unsafe locations due to full truck stops. Participants recommended that rest areas be spaced 50–200 km apart and equipped with essential amenities, including washrooms, running water, and showers. The study concludes that the current infrastructure in Saskatchewan is inadequate for supporting LHTD safety, contributing to fatigue and illegal parking. The authors recommend expanding truck stops and rest areas, particularly in underserved regions like Yorkton and Prince Albert, to ensure drivers have access to safe parking every 4 hours. They also suggest creating a nationwide inventory of parking facilities to help drivers plan routes. These findings provide evidence-based guidance for policymakers to implement environmental interventions that reduce fatigue-related crashes and improve occupational safety for truck drivers.
