Federal regulation allows truck drivers to use sleeper berths to accumulate eight hours of off-duty rest in two separate periods. Because sleep disruption may cause fatigue and deterioration of performance, a study was conducted to evaluate the association between sleeper-berth use in two periods and tractor-trailer driver fatality. Using Bureau of Motor Carrier Safety Reports, crashes that resulted in tractor-trailer driver fatality were compared with property damage crashes. After adjusting for confounding variables by logistic regression, tractor-trailer driver fatality was found to be significantly associated with sleeper-berth use in two shifts (odds ratio = 3.05). Statistically significant but weaker associations were found between driver fatality and rural district, night driving, gross vehicle weight of 72,000 pounds or more, single-vehicle collision, intercity trip, and employment on an occasional basis.
联邦法规允许卡车司机使用卧铺，分两个时间段累计八小时的非执勤休息时间。由于睡眠中断可能导致疲劳和工作表现下降，因此开展了一项研究，以评估分两个时间段使用卧铺与牵引式挂车司机死亡之间的关联。利用机动车承运人安全报告局的数据，将导致牵引式挂车司机死亡的撞车事故与财产损失撞车事故进行了比较。通过逻辑回归对混杂变量进行调整后，发现牵引式挂车司机死亡与分两班使用卧铺显著相关（优势比 = 3.05）。在司机死亡与农村地区、夜间驾驶、车辆总重72,000磅或以上、单车碰撞、城际行程以及偶尔就业之间，发现了具有统计学意义但较弱的关联。
