Read the first 7 TruckDisp Advanced Hours of Service (HOS) flashcards as text

  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?

    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.

  2. When does a new 14-hour on-duty window begin for a property-carrying driver?

    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.

  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?

    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.

  4. How should a dispatcher respond if a driver reports they falsified their logbook to meet a delivery deadline?

    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.

  5. Which FMCSA regulation part specifically governs Hours of Service for commercial motor vehicle drivers?

    Answer: 49 CFR Part 395

    49 CFR Part 395 contains the Hours of Service regulations for commercial motor vehicle drivers.

  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?

    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.

  7. What is the primary benefit to a dispatcher of proactively managing driver HOS 3–4 hours before a shift ends?

    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.
