FMCSA hours of service rules: a practical summary

Federal hours-of-service (HOS) rules limit when a covered commercial motor vehicle driver may drive, how long the driver may be on duty, and what rest is required. They do not amount to one universal “11 hours on, 10 hours off” rule. Property-carrying and passenger-carrying operations have different daily limits, and exceptions depend on the operation. Carriers should first establish whether 49 CFR Part 395 applies to the driver and trip, then use the current FMCSA HOS summary and the regulation for the actual schedule.

The direct answers for a typical property-carrying driver are: up to 11 hours driving after 10 consecutive hours off duty; no driving beyond the 14th consecutive hour after coming on duty following that rest; a 30-minute interruption after 8 cumulative hours of driving; and no driving after 60 or 70 on-duty hours in 7 or 8 consecutive days, depending on the carrier's operation. An eligible 34-hour off-duty period can restart the 7/8-day calculation. These are separate tests. Meeting one does not erase the others.

Who is covered?

FMCSA says HOS generally applies to carriers and drivers operating commercial motor vehicles in interstate commerce. Its HOS overview gives the federal CMV thresholds, including a vehicle with a gross vehicle weight rating or gross combination weight rating of 10,001 pounds or more, certain passenger capacities, and vehicles transporting placardable hazardous materials. Coverage is not decided by CDL status alone. Intrastate operations may follow state rules, and certain operations have federal exceptions. A carrier must check the vehicle, use, route, jurisdiction and any applicable exception before assigning a schedule.

The driver and dispatcher should not guess that a van, local trip or non-CDL driver is automatically outside HOS. Equally, a company should not apply property-carrier numbers to a passenger service. If the carrier operates both, establish the rule set for each driver and trip in the scheduling system and training materials.

Property-carrying limits

For example, a property driver begins work at 06:00 after a qualifying 10-hour rest. Without an applicable exception, the 14-hour driving window reaches 20:00, even if the driver spends an hour off duty in the afternoon. The driver still must stay within the 11-hour driving total and meet the 30-minute break rule. The example illustrates separate clocks; actual duty-status entries and any split-sleeper or adverse-condition provision require a current rule-specific check.

Loading, inspection and other work can count toward on-duty time even when the vehicle is stationary. Scheduling only by distance can therefore underestimate hours used. Dispatch should also allow for foreseeable loading queues and the time to reach a safe stopping location without turning an exception into a routine planning assumption.

Passenger-carrying limits are different

FMCSA's side-by-side summary gives passenger drivers a 10-hour driving limit after 8 consecutive hours off duty. They generally may not drive after being on duty for 15 hours following that rest; off-duty time is not counted in that 15-hour on-duty total. The 60/70-hour on-duty limit also applies. The property-driver 30-minute break requirement in the FMCSA table is not shown as a passenger-driver rule. Passenger operations have their own sleeper-berth and adverse-driving provisions. Do not move a bus-driver itinerary onto the 11/14 property schedule or vice versa.

Passenger routes often add pre-trip inspection, boarding, waiting and post-trip work. The carrier needs to count duty time under the applicable definitions and ensure a driver is not scheduled to continue driving once the relevant limit is reached.

Short-haul does not mean “no HOS rules”

Under the federal short-haul exception described in FMCSA's HOS summary, an eligible driver operates within 150 air miles of the normal work reporting location and reports to and returns to that location within 14 consecutive hours. The exception is principally from the Part 395 record-of-duty-status requirements identified by FMCSA; it does not mean the driver has unlimited driving time or no other safety duties. The carrier must keep the required time records and monitor whether the trip still qualifies. An “air mile” is not the same as a road-mile route length.

If a driver sometimes goes beyond the radius or otherwise fails a condition, check what records are required for that day and whether ELD rules apply. Do not label a driver permanently short-haul based only on the employer's usual pattern. Check the current exceptions in the regulation and FMCSA guidance for the particular operation.

ELD and logbook boundary

An electronic logging device (ELD) is a recording method, not a separate set of driving limits. FMCSA's ELD rule overview says most drivers required to maintain records of duty status under Part 395 must use an ELD, subject to limited exceptions. Drivers qualifying for the short-haul recordkeeping exception may use timecards instead; the ELD rule also describes limited paper-log, driveaway-towaway and older-vehicle exceptions. Do not assume every carrier's current software records a compliant ELD log. A document-management or certificate-reminder platform is not automatically an FMCSA-registered ELD.

Carriers should define who reviews duty-status records, unidentified driving, edits, supporting documents and potential violations. Drivers need to understand duty states, rest requirements and what to do if the device fails. The carrier should confirm the ELD is registered and used according to FMCSA's current requirements; marketing descriptions of “HOS tracking” do not establish compliance.

Exceptions and flexible provisions need their exact conditions

FMCSA's rules include provisions for adverse driving conditions, sleeper-berth splits and particular operations. For property drivers, FMCSA's 2020 rule permits certain 7/3 or 8/2 sleeper-berth pairings that total at least ten hours, with a qualifying berth period. The adverse-driving provision can extend the relevant driving limit/window by up to two hours when its conditions are met. These are not a standing two-hour buffer for a route that was poorly scheduled. The legal definition and duty-status record matter.

FMCSA's 2026 HOS page describes pilot programmes testing additional flexible sleeper-berth and split-duty options. Pilot participation or proposed flexibility is not the general HOS rule for every driver. Before relying on a waiver, emergency declaration, pilot, agricultural exception, 16-hour provision or state rule, verify its exact text, eligibility, geography, dates and documentation on the day of operation. Avoid baking a temporary exception into a permanent driver handbook.

Carrier and driver workflow

1. Classify the operation. Determine federal versus intrastate jurisdiction, property versus passenger rules, and whether the vehicle and trip are covered.
2. Identify any exact exception. Record why it applies, who checked it and when it ends. A short-haul claim needs the actual reporting location, radius and duty period.
3. Plan all four clocks where relevant. Check daily driving, driving window/on-duty limit, break and rolling 60/70 hours, including other on-duty work.
4. Check the recording method. Determine whether records of duty status and an ELD are required. Keep the required time and supporting records in the form the rule permits.
5. Brief the driver and dispatcher. The people assigning work should see how delays, extra stops and split-duty decisions affect the schedule. A driver should know whom to contact before an approaching limit becomes a roadside problem.
6. Review actual records. Investigate unassigned driving, edits or repeated exceptions. Correct unsafe scheduling practices; do not simply edit logs to make a dashboard turn green.
7. Recheck changes. Refresh the policy when FMCSA rules, exceptions or operations change. State rules and other DOT obligations may also apply to the fleet.

Frequent mistakes

• Treating the 14-hour property window as 14 hours of driving, or assuming a meal stop always pauses it.
• Counting only driving time toward the rolling 60/70 on-duty total.
• Applying property limits to passenger-carrying trips.
• Assuming short-haul removes all HOS restrictions or never requires an ELD regardless of actual trips.
• Treating a 2026 pilot as a general rule.
• Assuming a compliance platform that stores records is an ELD or calculates legal HOS availability without proof.
• Planning routes with an adverse-condition exception as routine spare time.

Next step: Compare your operation with FMCSA's HOS summary and current Part 395, then make dispatch and driver records match the applicable rule. If a verified Complys US product route supports DOT document or qualification tracking, it may be linked for that specific function after implementation review.
