NPR (6/6, Detrow) reported on its website that the US “Department of Transportation is clarifying a new rule regulating how much time truck drivers hauling materials to and from” oil and gas “drilling sites can spend on the road.” According to the report, “drivers are limited to 14 hours a day, and the DOT says time spent loading and unloading material needs to count toward that limit.” NPR reports that this “clarification comes two weeks after a New York Times report about how many drivers were working more than 14 hours by not counting on-site time.”
