EFFECTS OF OPERATING PRACTICES ON COMMERCIAL DRIVER ALERTNESS

The Office of Motor Carrier and Highway Safety, Federal Highway Administration, funded this study with the American Trucking Association's Foundation to (1) assess the effects of truck driver loading or unloading on subsequent driver alertness and (2) measure and document truck drivers' performance on a 14-hours-on (with 12 hours driving)/10-hours-off daytime schedule coupled with weekend recovery process over a 58-hour off-duty period between two successive weeks of simulated driving. This study was not specifically a test of fatigue but rather was designed to investigate the degree of impairment of driver performance brought about by physical activities and extended periods of driving. The study concluded 1. the effects of loading and unloading cargo were mixed in that loading and unloading driver performance is correlated to time-of-day and time on task; 2. drivers recovered baseline performance within 24 hours of the end of a driving week and were seen to be fit to resume duty after 36 hours and 3. a schedule of 14 hours on duty/10 hours off duty for a 5-day week did not appear to produce significant cumulative driver fatigue.
