Which statement best summarizes FMCSA Hours of Service requirements?

• A. Maximum driving time per shift is 11 hours; 14-hour on-duty window; 30-minute break after 8 hours; 60/70-hour on-duty limits; a 34-hour restart is allowed.
• B. Maximum driving time per shift is 12 hours.
• C. There is no required break during shifts.
• D. On-duty limits reset every week.

Answer: (D)

FMCSA Hours of Service are built to control driving time, require adequate rest, and provide a way to refresh the limits when needed. The essential rules include a maximum of 11 hours of driving in a duty period, a 14-hour on-duty window, a requirement for a 30-minute break after about 8 hours of on-duty time, and a cap on total on-duty hours (60 hours in 7 days or 70 hours in 8 days). Importantly, the “reset” of those on-duty limits happens through a 34-hour restart of off-duty time, which refreshes the weekly clock. This reset isn’t automatic every calendar week; it only occurs after completing the 34 consecutive hours off duty.
