Background Fatigue and sleep deprivation are important safety issues for long-haul truck drivers.
Methods We conducted round-the-clock electrophysiologic and performance monitoring of four groups of 20 male truck drivers who were carrying revenue-producing loads.
We compared four driving schedules, two in the United States (five 10-hour trips of day driving beginning about the same time each day or of night driving beginning about 2 hours earlier each day) and two in Canada (four 13-hour trips of late-night-to-morning driving beginning at about the same time each evening or of afternoon-to-night driving beginning 1 hour later each day).
Results Drivers averaged 5.18 hours in bed per day and 4.78 hours of electrophysiologically verified sleep per day over the five-day study (range, 3.83 hours of sleep for those on the steady 13-hour night schedule to 5.38 hours of sleep for those on the steady 10-hour day schedule).
These values compared with a mean (±SD) self-reported ideal amount of sleep of 7.1±1 hours a day.
For 35 drivers (44 percent), naps augmented the sleep obtained by an average of 0.45±0.31 hour.
No crashes or other vehicle mishaps occurred.
Two drivers had undiagnosed sleep apnea, as detected by polysomnography.
Two other drivers had one episode each of stage 1 sleep while driving, as detected by electroencephalography. (...)
