FMCSA hours of service rules are among the most closely scrutinized regulations in commercial trucking — and for owner-operators, a single logbook violation can mean an out-of-service order, a CSA score hit, and real financial loss. Understanding exactly what the rules require, which exemptions apply to your operation, and how ELD requirements interact with HOS compliance is essential for staying on the road and out of regulatory trouble. Here is a complete guide to FMCSA hours of service rules for owner-operators in 2026.
FMCSA Hours of Service Rules: Quick-Reference Summary
| Rule | Limit | Notes |
|---|---|---|
| Daily Driving Limit | 11 hours | After 10 consecutive hours off duty |
| 14-Hour On-Duty Window | 14 hours | Clock starts at first duty activity; cannot extend with breaks |
| 30-Minute Break | Required after 8 hours driving | Must be off duty or sleeper berth |
| Weekly Limit (7-day cycle) | 60 hours | Resets with 34-hour restart |
| Weekly Limit (8-day cycle) | 70 hours | Resets with 34-hour restart |
| 34-Hour Restart | 34 consecutive off-duty hours | Resets the 60/70-hour weekly clock |
| Sleeper Berth Split (8/2) | 8 hrs berth + 2 hrs off | Neither period counts against 14-hr window |
| Sleeper Berth Split (7/3) | 7 hrs berth + 3 hrs off | At least one period must be 7+ hrs in berth |
Hours of Service Rules: The Core Limits
FMCSA hours of service regulations are codified at 49 CFR Part 395. The rules establish maximum limits on how much a property-carrying commercial motor vehicle driver can drive and remain on duty in a given day and week. The three primary daily limits that govern most owner-operator operations are the 11-hour driving limit, the 14-hour on-duty window, and the 30-minute break requirement.
The 11-hour driving limit allows a driver to drive a maximum of 11 hours after taking 10 or more consecutive hours off duty. Hours off duty reset the 11-hour driving clock. If a driver has used 11 hours of driving time — regardless of how much time remains in the 14-hour window — they must go off duty for at least 10 consecutive hours before driving again. The 11-hour limit applies only to actual driving time, not to all on-duty time.
The 10-hour off-duty requirement is the minimum reset period for the daily driving clock. Drivers must take at least 10 consecutive hours off duty before beginning a new period of driving. Time spent in a sleeper berth (in the qualifying split configuration) can count toward this off-duty reset under specific conditions. There is no provision that allows the 10-consecutive-hour off-duty requirement to be split for property-carrying operations outside of the sleeper berth rules.
The 14-Hour On-Duty Window
The 14-hour rule establishes an on-duty window that begins when a driver comes on duty after the required off-duty period. A driver may not drive beyond the 14th hour after coming on duty, regardless of how many hours of driving time remain. If a driver comes on duty at 6:00 a.m., the 14-hour window closes at 8:00 p.m. — even if the driver has only used 8 of their 11 available driving hours. Any driving after 8:00 p.m. would be a violation.
Time spent off duty during the 14-hour window — for example, a 2-hour break for a meal — does not pause or extend the 14-hour clock. The window runs continuously from the moment the driver comes on duty. This is one of the most important practical distinctions for owner-operators: taking off-duty time during the workday does not stop the clock. The only ways to extend driving opportunities into a later period are to use the sleeper berth split, take the full 10-hour off-duty reset, or qualify for an applicable exemption.
Pre-trip inspection time counts as on-duty time and therefore counts against the 14-hour window. Loading, unloading, fueling, and all other work activities are also on-duty time. Owner-operators who begin pre-trip inspection and loading before departing should account for this time when planning their driving day — the 14-hour clock starts with the first on-duty activity, not with the first mile driven.
The 30-Minute Break Requirement
A driver who has driven for 8 cumulative hours without an interruption of at least 30 minutes must take a break of at least 30 minutes before continuing to drive. The break must be spent in the sleeper berth, off duty, or on duty not driving — all three qualify. The break requirement resets after the 30-minute interruption; a driver who takes a qualifying break can then drive for another 8 cumulative hours before the next required break.
The 30-minute break requirement was modified in 2020 to allow the break to be satisfied by on-duty not-driving time, not just off-duty time. This change benefits drivers who need to take breaks at shipper or receiver facilities where they remain on duty during loading or unloading. If a driver is on the dock for 45 minutes waiting for a load — on duty, not driving — that time satisfies the 30-minute break requirement, even though the driver is technically on duty during that period.
The break requirement does not apply to short-haul drivers operating under the short-haul exemption. If a driver uses the 150 air-mile short-haul exemption, the 30-minute break requirement does not apply to that day’s operation. This is one of several practical advantages of the short-haul exemption for eligible owner-operators.
60/70-Hour Weekly Limits and the 34-Hour Restart
Property-carrying drivers are subject to either a 60-hour limit over 7 consecutive days or a 70-hour limit over 8 consecutive days, depending on which cycle the carrier has elected to use. Most over-the-road owner-operators operate under the 70-hour/8-day cycle. A driver who has reached the applicable weekly limit may not drive again until enough hours have “dropped off” the rolling 7- or 8-day window, or until the driver has taken a qualifying 34-hour restart.
The 34-hour restart provision allows a driver to reset their weekly cumulative on-duty hours to zero by taking at least 34 consecutive hours off duty. After a valid 34-hour restart, the driver’s hours of service cycle begins fresh — all previous on-duty hours in the 7- or 8-day window are effectively zeroed out. The 34-hour restart can be used once per 168 hours (one week), measured from the start of the previous restart.
The 34-hour restart previously included a mandatory provision requiring two periods of 1:00–5:00 a.m. within the 34 hours off duty. FMCSA suspended this provision in 2015 after industry pressure, and as of 2026, the 34-hour restart requires only 34 consecutive off-duty hours without any specific nighttime window requirement. Owner-operators who previously had to plan their restarts around the 1–5 a.m. requirement should be aware that this restriction no longer applies.
Sleeper Berth Provisions
Drivers who operate CMVs equipped with a sleeper berth can use split sleeper berth time to extend their driving window in ways that are not available to non-sleeper drivers. The current sleeper berth split rule — which took effect in 2020 — allows a driver to split their required 10-hour off-duty period into two periods: one of at least 7 consecutive hours in the sleeper berth, and one of at least 2 consecutive hours (either in the sleeper berth or off duty). The two periods must add up to at least 10 hours.
The key benefit of the sleeper berth split is that neither period counts against the 14-hour driving window. When using the split, the 14-hour clock effectively pauses during both qualifying sleeper berth periods. A driver can take a 7-hour sleeper berth break in the middle of their day without that time running against their 14-hour window, which allows for greater flexibility in long-haul scheduling.
There are conditions on the order and pairing of sleeper berth periods. A driver using the split must ensure that neither period is used as a daily reset — the full 10-hour reset rule still applies if the driver wishes to start a completely fresh driving period. The sleeper berth rules are among the more complex elements of HOS compliance, and owner-operators operating team-driving setups or long-haul routes with irregular rest patterns should carefully review how their specific operational patterns interact with the sleeper berth provisions.
Key HOS Exemptions
FMCSA has established several exemptions from standard HOS rules for specific operational contexts. The adverse driving conditions exemption allows drivers who encounter unexpected adverse driving conditions — such as traffic from an accident or unexpected severe weather — to extend their driving limit by up to 2 hours beyond the normal 11-hour limit. The extension applies only when the conditions were encountered en route and were not foreseeable when the driver came on duty. This exemption does not extend the 14-hour window.
The agricultural exemption provides HOS relief for drivers transporting agricultural commodities from farm to first point of processing or storage, within a 150 air-mile radius of the source. During planting and harvest seasons, FMCSA and many states also issue broader agricultural exemptions that suspend standard HOS rules for qualifying agricultural operations. The agricultural exemption is time-limited and operation-specific; owner-operators should verify the current scope of any applicable exemption before relying on it.
The oilfield exemption applies to drivers transporting oilfield equipment, materials, or supplies to or from an active drilling or production site. These drivers are exempt from the 14-hour on-duty window and may take off-duty rest breaks of any length to restart the driving clock, as long as they take the required 10 consecutive hours of rest. The oilfield exemption does not relax the 11-hour driving limit. Construction, utility service vehicles, and ground water well drilling operations have separate exemption provisions that relax specific elements of standard HOS rules.
Short-Haul Exemption
The short-haul exemption is one of the most operationally significant HOS provisions for owner-operators whose work keeps them within a relatively local area. Under the short-haul exemption, a driver who operates within a 150 air-mile radius of their normal work reporting location and returns to that location to be released within 14 hours is exempt from the ELD requirement and the 30-minute break requirement. The driver must still comply with the 11-hour driving limit and the 10-hour off-duty reset between shifts.
To use the short-haul exemption, the driver must report to and be released from the same location each day, and may not use the exemption more than 8 days in any 30-day period if the driver’s operations would otherwise require a CDL. For CDL-required operations, the 150 air-mile radius is measured from the normal work reporting location. The exemption is available without any advance filing with FMCSA — it applies automatically to qualifying operations.
The short-haul exemption eliminates the ELD requirement because drivers using this exemption are not required to maintain Records of Duty Status (RODS). Instead, drivers must meet time record requirements — recording the time on-duty, time off-duty, and total hours for each day of operation. These time records must be retained for 6 months. Owner-operators who occasionally operate beyond the 150 air-mile radius or who are released from work after the 14-hour window lose the exemption for that day and must comply with full HOS rules including ELD use for that day’s operation.
ELD Requirements and HOS Recording
The FMCSA ELD mandate (49 CFR Part 395) requires most CMV drivers who are required to maintain Records of Duty Status to use a registered, FMCSA-certified electronic logging device. ELDs automatically record engine hours, vehicle movement, miles driven, and location data and link this data to the driver’s duty status entries, creating a tamper-resistant record of hours of service compliance. Paper logs are no longer acceptable for drivers subject to the ELD mandate.
Owner-operators who drive CMVs manufactured before model year 2000 may use automatic onboard recording devices (AOBRDs) or paper logs instead of ELDs — the older engine control modules in pre-2000 vehicles are not compatible with the synchronization requirements of certified ELDs. Drivers who operate under the short-haul exemption, as discussed above, are also not subject to the ELD mandate for qualifying days of operation. Driveaway-towaway operations and drivers who operate the applicable CMV for 8 or fewer days within any 30-day period are also exempt.
ELDs must be registered on FMCSA’s technical specifications and must appear on the FMCSA ELD registered devices list. Carriers and owner-operators may not use devices that are not on this list. The ELD must be mounted in the cab and visible to the driver and to roadside inspectors. Drivers must be able to transfer log data to enforcement officers via telematics (wireless) or via USB/Bluetooth. During roadside inspections, inspectors can review ELD data directly on the device’s display or through a printed or transferred output.
Personal Conveyance and Yard Moves
Personal conveyance and yard moves are two special-use designations that allow drivers to record CMV movement as off-duty time rather than on-duty driving time under specific, limited circumstances. Both designations are subject to FMCSA guidance and abuse of either can result in HOS violations.
Personal conveyance (PC) allows a driver to move the CMV for personal reasons — not in furtherance of commerce — while recording the time as off-duty. Common examples include driving from a truck stop to a nearby restaurant, relocating from a shipper’s lot to a nearby rest area after being released from duty, or driving home at the end of a run where the driver is no longer under any obligation to the carrier. PC may not be used to extend a driver’s day by covering commercial miles — the driver must be genuinely off duty with no current obligation to deliver freight. Driving under PC while carrying a loaded trailer is an area of particular scrutiny.
Yard moves (YM) allow a driver to record CMV movement as on-duty not-driving time — rather than driving time — when operating in a facility yard at slow speeds under the direct supervision of a yard manager. Yard moves do not count against the 11-hour driving limit but do count against the 14-hour on-duty window. Yard moves are specifically intended for repositioning within a secure, controlled yard environment — not for any movement on public roads, regardless of how short the distance.
2026 FMCSA HOS Pilot Programs: What Owner-Operators Need to Know
In September 2025, the FMCSA announced two pilot programs that could significantly reshape hours of service flexibility for owner-operators. While these programs are not yet in effect for all carriers, they signal where federal HOS policy may be heading — and owner-operators should monitor them closely.
Split Duty Period (SDP) Pilot Program
The Split Duty Period pilot allows drivers to pause the 14-hour on-duty window by taking an off-duty break of up to 3 hours. Under current rules, the 14-hour clock runs continuously once a driver begins their day. Under the SDP pilot, a qualifying off-duty rest period (minimum 30 minutes, maximum 3 hours) would effectively freeze the 14-hour window for that duration — giving drivers more flexibility to manage fatigue and traffic delays without losing drive time.
Flexible Sleeper Berth (FSB) Pilot Program
Current rules allow two sleeper berth split options: the 8/2 split and the 7/3 split. The Flexible Sleeper Berth pilot would expand those options to include a 6/4 split and a 5/5 split, provided both periods together total at least 10 hours. This gives team drivers and long-haul solo operators more control over their rest schedules without sacrificing compliance.
Neither pilot program replaces existing HOS rules for non-participating carriers. Monitor the FMCSA website for current enrollment details and eligibility requirements.
Frequently Asked Questions
Can I drive after 11 hours if I still have time left in my 14-hour window?
No. The 11-hour driving limit is a hard cap — once you have driven 11 hours in a shift, you may not drive again until you have taken at least 10 consecutive hours off duty. Time remaining in the 14-hour window does not extend your driving allowance past 11 hours. The 14-hour window and the 11-hour driving limit are separate, independent restrictions, both of which must be satisfied.
Does taking a 2-hour break extend my 14-hour window?
No. Off-duty breaks taken during your shift do not pause or extend the 14-hour on-duty window. The 14-hour clock runs continuously from the moment you come on duty until it expires, regardless of any off-duty breaks taken during that period. The only exceptions are the sleeper berth split provisions, which allow qualifying sleeper berth time to be excluded from the 14-hour window calculation.
How does the 34-hour restart work?
The 34-hour restart allows you to reset your cumulative weekly on-duty hours (60- or 70-hour clock) to zero by taking at least 34 consecutive hours off duty. After a valid restart, your weekly hours accumulation begins fresh. The restart can be used once every 168 hours (one week) measured from the beginning of your last restart. As of 2026, there is no required 1:00–5:00 a.m. window within the 34 hours — any 34 consecutive off-duty hours qualify.
Who qualifies for the short-haul exemption?
Drivers who operate within a 150 air-mile radius of their normal work reporting location, return to that location to be released from work each day, and are released within 14 hours of coming on duty qualify for the short-haul exemption. Qualifying drivers are exempt from ELD requirements and the 30-minute break rule. The driver must still comply with the 11-hour driving limit, the 10-hour off-duty reset, and the 60/70-hour weekly limits.
What happens if I run out of hours on the road?
If you exhaust your available driving hours — whether by reaching the 11-hour driving limit or the end of the 14-hour window — you must stop driving immediately and go off duty for the required 10 consecutive hours. Continuing to drive after HOS limits are exhausted is a serious violation that can result in roadside out-of-service orders, civil monetary penalties, and CSA score increases. If you anticipate running out of hours before reaching a safe parking location, plan ahead by identifying truck stops or rest areas along your route.
