TruckDisp Advanced Hours of Service (HOS) Flashcards

A driver is using the 16-hour short-haul exception. Which of the following conditions must be met for this exception to be valid?

Answer: The driver must return to the work reporting location every day.

The 16-hour short-haul exception allows a driver to extend their 14-hour driving window to 16 hours once per 7-day period (or after a 34-hour reset). A key requirement is that the driver must have started and must end their day at the same work reporting location.

A driver encounters an unforeseen traffic jam due to a major accident, which will cause them to exceed their 11-hour driving limit by 90 minutes to reach the nearest safe parking. Under which rule can the driver legally complete this drive?

Answer: Adverse Driving Conditions Exception

The Adverse Driving Conditions exception allows a driver to extend their maximum driving time (11 hours) and their driving window (14 hours) by up to 2 hours if they encounter unexpected adverse conditions. A major, unforeseen accident causing a traffic jam qualifies for this exception.

A driver plans to use the split-sleeper berth provision to pause their 14-hour clock. Which of the following combinations is a valid split?

Answer: 8 hours in the sleeper berth and 2 hours off-duty.

The split-sleeper berth rule requires two qualifying rest periods totaling at least 10 hours. One period must be at least 7 consecutive hours in the sleeper berth, and the other must be at least 2 consecutive hours either off-duty or in the sleeper berth. The 7/3 split is a valid combination that satisfies these requirements.

A driver has been on-duty for 60 hours in the last 7 days. The carrier operates on a 70-hour/8-day rule. What is the driver's status?

Answer: The driver's status is compliant and they can continue working.

The 60/7 and 70/8 rules are distinct limits based on the carrier's operation. If the carrier operates under the 70-hour/8-day rule, the driver's 60 hours of on-duty time in 7 days is irrelevant; their limit is 70 hours in any 8 consecutive days. Therefore, the driver is compliant and has hours available.

When is a driver required to take a 30-minute break under federal HOS rules?

Answer: After 8 cumulative hours of driving time.

The 30-minute break rule states that a driver must take a 30-minute break after accumulating 8 hours of driving time, not on-duty time. The break can be taken as off-duty, sleeper berth, or on-duty not driving.

A driver uses Personal Conveyance (PC) to travel from their last delivery location to a hotel 15 miles away. Which statement is true regarding this move?

Answer: This is a valid use of PC, and the time does not count against the 14-hour clock.

Using a commercial motor vehicle for personal transportation from a final work site to a nearby lodging is a specifically allowed use of Personal Conveyance. This time is logged as 'Off-Duty' and does not count towards the 14-hour on-duty window or the 70-hour weekly limit, regardless of whether the truck is laden or unladen.
