Truck Dispatcher TruckDisp Advanced Hours of Service (HOS) 2 — Questions and Answers
Question 1: Under the short-haul exemption, a driver operating within a 150 air-mile radius is exempt from which HOS requirement?
- Electronic Logging Device (ELD) (Correct answer)
- The 11-hour driving limit
- The 14-hour on-duty window
- The 30-minute break rule
Correct answer: Electronic Logging Device (ELD)
Drivers qualifying for the short-haul exemption are not required to use an ELD and may use paper timecards instead.
Question 2: A dispatcher receives a load offer but the driver has only 3 hours left in their 14-hour window. The trip requires 4 hours of driving. What is the best course of action?
- Instruct the driver to drive faster to finish in time
- Assign the load to a driver with sufficient HOS remaining (Correct answer)
- Tell the driver to take a 30-minute break to reset the 14-hour clock
- Have the driver log off-duty at a shipper facility
Correct answer: Assign the load to a driver with sufficient HOS remaining
A 30-minute break does not extend the 14-hour window, so assigning the load to a compliant driver is the only legal option.
Question 3: What is the maximum number of hours a property-carrying driver may drive after 34 consecutive hours off duty (the restart)?
- 60 hours in 7 days
- 70 hours in 8 days
- A fresh 60/70-hour cycle, depending on the carrier's schedule (Correct answer)
- 11 hours driving followed by a new 14-hour window
Correct answer: A fresh 60/70-hour cycle, depending on the carrier's schedule
The 34-hour restart resets the driver's 7-day or 8-day cycle, allowing them to begin a new 60- or 70-hour clock.
Question 4: Which of the following activities counts as 'on-duty not driving' time for HOS purposes?
- Sleeping in the sleeper berth
- Waiting at a shipper's dock for loading (Correct answer)
- Taking a 10-hour rest break at a truck stop
- Personal conveyance to a restaurant
Correct answer: Waiting at a shipper's dock for loading
Time spent waiting at a shipper or receiver dock is classified as on-duty not driving time and counts against the 14-hour window.
Question 5: A driver uses the sleeper berth provision, splitting rest into a 7-hour sleeper period and a 3-hour off-duty period. How is the 14-hour window affected?
- It is completely reset after the 7-hour sleeper period
- The 3-hour off-duty period is excluded from the 14-hour calculation (Correct answer)
- Both periods must be used together to get a full 10-hour restart
- The 14-hour clock cannot be extended by the sleeper berth provision
Correct answer: The 3-hour off-duty period is excluded from the 14-hour calculation
Under the sleeper berth split, the shorter qualifying period (at least 2 hours) is excluded from the 14-hour window calculation.
Question 6: Which exemption allows a driver transporting agricultural commodities to drive beyond the normal HOS limits during planting and harvest seasons?
- Agricultural exemption (Correct answer)
- Short-haul exemption
- Oilfield operations exemption
- Emergency declaration exemption
Correct answer: Agricultural exemption
The agricultural exemption permits extended hours for drivers hauling agricultural commodities within a 150 air-mile radius of the source during planting and harvest.
Question 7: When a federal or state emergency declaration is in effect, how does it impact HOS rules for affected carriers?
- HOS rules are suspended entirely for all drivers nationwide
- Drivers may operate under relaxed or suspended HOS rules only in the declared emergency area (Correct answer)
- Drivers need written DOT approval to operate beyond HOS limits
- Only passenger-carrying vehicles are exempt during emergencies
Correct answer: Drivers may operate under relaxed or suspended HOS rules only in the declared emergency area
Emergency exemptions apply specifically to the geographic area covered by the declaration and only for loads directly supporting the emergency.
