Truck Dispatcher TruckDisp Advanced Hours of Service (HOS) 5 — Questions and Answers
Question 1: A driver is placed on the 'sleeper berth' status for 8 hours and then 'off-duty' for 2 hours. Do these periods satisfy the sleeper berth split provision?
- Yes, because 8 + 2 = 10 total hours of rest (Correct answer)
- No, because the shorter period must be at least 2 hours and the longer at least 7 hours, but neither can be on-duty time
- Yes, as long as neither period is less than 2 hours
- No, the split requires both periods to be in the sleeper berth
Correct answer: Yes, because 8 + 2 = 10 total hours of rest
A valid split requires one sleeper berth period of at least 7 hours and a second period of at least 2 hours (which may be sleeper berth or off-duty), totaling 10 hours.
Question 2: When does a new 14-hour on-duty window begin for a property-carrying driver?
- When the driver starts the engine
- When the driver logs their first on-duty activity after a qualifying rest period (Correct answer)
- After exactly 24 hours from the previous shift start
- When the dispatcher assigns the first load of the day
Correct answer: When the driver logs their first on-duty activity after a qualifying rest period
The 14-hour window begins the moment a driver logs any on-duty activity following a qualifying off-duty or sleeper berth rest period.
Question 3: Under FMCSA rules, which of the following is true about a driver who discovers they cannot legally complete a trip due to HOS limits while en route?
- The driver must immediately pull over and park regardless of location
- The driver may drive up to 2 additional hours to reach a safe parking location (Correct answer)
- The driver may continue to the destination if it is within 50 miles
- The driver must contact FMCSA for a special permit to complete the trip
Correct answer: The driver may drive up to 2 additional hours to reach a safe parking location
FMCSA allows drivers to drive up to 2 additional hours beyond their limit if needed to reach a safe location when no safe stopping point is immediately available.
Question 4: How should a dispatcher respond if a driver reports they falsified their logbook to meet a delivery deadline?
- Overlook it as a one-time incident to maintain the customer relationship
- Immediately report it internally and remove the driver from service pending investigation (Correct answer)
- Advise the driver to correct the logs retroactively on the ELD
- File the logs and hope a roadside inspection does not occur
Correct answer: Immediately report it internally and remove the driver from service pending investigation
Log falsification is a serious federal violation; dispatchers who knowingly allow it can face personal liability, and the driver must be removed from service pending review.
Question 5: Which FMCSA regulation part specifically governs Hours of Service for commercial motor vehicle drivers?
- 49 CFR Part 382
- 49 CFR Part 395 (Correct answer)
- 49 CFR Part 391
- 49 CFR Part 396
Correct answer: 49 CFR Part 395
49 CFR Part 395 contains the Hours of Service regulations for commercial motor vehicle drivers.
Question 6: A dispatcher notices that a driver's ELD shows 'unassigned driving time' for a 30-minute segment. What is the carrier's obligation regarding this data?
- Delete the unassigned segment to keep records clean
- Assign the segment to the correct driver as soon as possible (Correct answer)
- Leave it unassigned; it does not count toward any driver's HOS
- Report it to FMCSA within 24 hours
Correct answer: Assign the segment to the correct driver as soon as possible
Carriers must review unassigned driving events and assign them to the correct driver promptly to maintain accurate and compliant ELD records.
Question 7: What is the primary benefit to a dispatcher of proactively managing driver HOS 3–4 hours before a shift ends?
- It reduces the carrier's fuel costs
- It allows time to arrange relay drivers, adjust appointments, or reroute loads before a violation occurs (Correct answer)
- It eliminates the need to file an adverse conditions exception
- It resets the driver's 14-hour window automatically
Correct answer: It allows time to arrange relay drivers, adjust appointments, or reroute loads before a violation occurs
Proactive HOS management gives dispatchers a window to make operational adjustments before the driver runs out of legal driving time, preventing service failures and violations.
