A property-carrying driver’s day is bounded by four rules in § 395.3(a), and they work together rather than in sequence. First, a driver may not drive without first taking 10 consecutive hours off duty. Second, a driver may not drive after a period of 14 consecutive hours after coming on duty following those 10 hours off. Third, a driver may drive a total of 11 hours during that 14-hour period. Fourth, driving is not permitted if more than 8 hours of driving time have passed without at least a consecutive 30-minute interruption of driving status.

The distinction that decides most real cases is between the 14 and the 11. The 14-hour window is a CLOCK: it starts when you come on duty and runs on wall time, through loading, waiting, meals and paperwork alike, and when it closes you may not drive again that shift no matter what is left of anything else. The 11 hours is a BUDGET: it only spends while the wheels are turning. A driver who loses five hours at a dock has lost them from the window, not from the budget — the 11 hours are intact and largely unusable, because there is no longer enough window left to spend them in. Off-duty time taken during the day does not pause the 14-hour clock; only a fresh 10 consecutive hours off duty starts a new one.

The 30-minute interruption is measured against driving time, not against the window. Once 8 hours of driving time have accumulated without a qualifying break, driving stops until one is taken. What qualifies is generous: off-duty time, sleeper berth time, on-duty-not-driving time, or a combination — so an unloading stop of half an hour can satisfy it while remaining on duty. One group of drivers is outside this requirement entirely: § 395.3(a)(3)(ii) excepts drivers who qualify for either short-haul exception in § 395.1(e)(1) or (2), which § 7.5 takes up. The panel gathers the whole envelope, weekly limits included.
