FMCSA Hours of Service Guide for Property-Carrying Drivers

Under 49 CFR §395.3, a property-carrying driver may drive up to 11 total hours after taking at least 10 consecutive hours off duty. Driving time is the time spent at the controls of the commercial motor vehicle. Fueling, inspections, loading work, paperwork, and waiting while responsible for the vehicle can be on-duty time, but they do not themselves subtract from the 11-hour driving clock.

That distinction does not make non-driving work “free.” It consumes the 14-hour window and the weekly cycle. A driver who spends four hours at a shipper may still show substantial driving time but lack enough window to use it legally.

After the driver comes on duty following 10 consecutive hours off, a 14-consecutive-hour window begins. The driver may not drive after that window closes. Unlike a bank of work hours, the clock generally continues through meals, detention, loading, fueling, and other off-duty or on-duty periods.

The driver may perform non-driving work after the 14th hour if otherwise lawful, but cannot drive a commercial motor vehicle again until obtaining the required qualifying off-duty time. Dispatch should therefore plan from the start of the duty window—not only from the first highway mile.

A driver cannot continue driving after accumulating eight hours of driving without at least 30 consecutive minutes in a non-driving status. The break can be off duty, sleeper berth, on-duty not driving, or a consecutive combination of those statuses. A properly logged fuel stop or customer wait may satisfy the rule if it creates a full 30-minute interruption in driving.

The trigger is eight cumulative driving hours since the last qualifying interruption—not simply eight hours since coming on duty. The 30 minutes does not normally extend the 14-hour window, so waiting until the final part of the window can leave the driver compliant with the break rule but unable to complete the drive.

A carrier that does not operate commercial vehicles every day of the week generally uses the 60-hour/7-day limit. A carrier operating commercial vehicles every day may use the 70-hour/8-day limit. After reaching the applicable on-duty total, the driver may not drive until enough older hours fall outside the rolling period or a valid restart is completed.

This clock includes all on-duty time, not only driving for the current carrier. Work for another motor carrier and compensated non-motor-carrier work can affect availability. Before using a driver for the first time or intermittently, obtain the preceding duty-time information required by the rules.

A 34-hour restart may reset the applicable 7/8-day calculation, but it is optional. Sometimes a driver can regain enough recap hours sooner by waiting for older on-duty time to roll off. Compare the hours returned, appointment needs, parking, and revenue rather than assuming every week requires a restart.

The property-carrier sleeper provision in 49 CFR §395.1(g) permits two qualifying rest periods. One must be at least seven consecutive hours in the sleeper berth. The other must be at least two consecutive hours, in or out of the sleeper berth. Together they must total at least 10 hours, and neither period can be shorter than two hours.

When the two periods qualify as a pair, neither counts against the 14-hour window, and the driving and duty-window calculations are made from the end of the first qualifying period. The pairing must still keep total driving at or below 11 hours and driving inside the recalculated 14-hour limit.

Do not improvise a split after the schedule fails. Drivers and dispatchers should understand which period is the first qualifying break, which period completes the pair, and how the ELD displays available time. If the intended second period is interrupted or too short, the earlier calculation may no longer work.

The adverse-driving provision can extend the 11-hour driving limit and 14-hour driving window by up to two hours when qualifying adverse conditions are encountered. The rule is intended for conditions that could not reasonably have been known to the driver immediately before the duty day—or to the carrier immediately before dispatch.

Normal rush-hour traffic, a predictable construction zone, or weather already known when the trip was planned should not be treated automatically as adverse conditions. The extension does not erase fatigue or guarantee that movement is safe. Document what occurred, when it became known, and why the additional time was needed to complete the run or reach a safe place.

A qualifying driver may be exempt from the standard record-of-duty-status and ELD requirements when operating within a 150-air-mile radius—172.6 statute miles—of the normal work reporting location, returning there and being released within 14 consecutive hours, and meeting the required off-duty conditions. The carrier must maintain accurate time records for six months, including report time, release time, and total daily on-duty hours.

This is not a general exemption from hours of service. The driver must stay inside every condition on each day it is used. A load leaving the radius or a duty day exceeding the return-and-release limit can require a standard log, subject to the applicable rules. Confirm the exact operation and any limited ELD exception before dispatch.

A workable dispatch plan includes more than map mileage divided by highway speed. Begin with the delivery appointment, then build backward using realistic drive segments, fuel, inspections, congestion, weather, shipper time, receiver time, parking availability, and the driver's current cycle.

A legal plan is not necessarily a safe plan. FMCSA limits are maximums, not a requirement to drive until the clock reaches zero. A fatigued driver must not continue merely because the ELD shows time remaining.

• ✓Counting the 14-hour window as 14 hours of work that pauses during ordinary off-duty time.
• ✓Watching only the 11-hour drive clock while ignoring the weekly cycle.
• ✓Assuming any two sleeper periods create a valid split.
• ✓Logging loading, fueling, inspections, or compensated work as off duty when the status does not fit.
• ✓Using the adverse-driving exception for congestion or weather known before dispatch.
• ✓Calling a run “short haul” without meeting the radius, return, release, rest, and time-record conditions.
• ✓Planning arrival at the exact end of available time with no parking or delay buffer.

1. 1

   Read the current clocks

   Confirm drive, duty-window, break, and cycle availability directly from the driver's record.

2. 2

   Confirm the prior rest

   Identify the qualifying 10-hour rest, restart, or sleeper pairing supporting the calculation.

3. 3

   Build realistic time

   Include deadhead, inspections, loading, traffic, fuel, delivery, and parking.

4. 4

   Test every limit

   The same plan must fit the 11-hour, 14-hour, 30-minute, and 60/70-hour rules.

5. 5

   Set update points

   Recalculate after loading delay, route changes, weather, or appointment changes.

6. 6

   Protect a safe buffer

   Do not make compliance depend on perfect traffic or the last available parking space.
