Samenvatting
To better understand the issues surrounding commercial driver reliance upon in-vehicle sleeper berths for rest, ten focus groups were conducted with long-haul operators. These focus groups were held in eight cities across seven American states to provide a geographically diverse sample of long-haul drivers. Issues that were explored included factors affecting the quality and quantity of sleep that drivers receive in sleeper berths, drivers' physical and mental fatigue while on the road, and other related safety issues associated with long-haul truck operations where sleeper berths are used. The results of these focus groups are presented and reflect a wide variety of driver comments, perceptions, suggestions, and recommendations. (A)
