Final answer:
In a 14 consecutive day cycle, after accumulating 70 hours of on-duty time, a driver must not continue to drive until they have had at least 34 consecutive off-duty hours.
Step-by-step explanation:
When operating on a 14 consecutive day cycle in the context of commercial driving regulations such as those for truck drivers, once a driver has accumulated 70 hours of on-duty time, regulations require that driver to take an extended period of off-duty time before continuing to drive. The correct amount of consecutive off-duty hours required is 34 hours, which serves to reset the driver’s 70-hour clock. This regulation is designed to ensure drivers have sufficient rest and to help prevent the negative effects of fatigue on driver performance and road safety.
