The most rigid number in your operating day may finally be getting a pause button. FMCSA confirmed this week that it has finished pre-testing two hours-of-service pilot programs — one that lets drivers pause the 14-hour driving window for up to three hours, and one that lets them split their 10 hours of rest into combinations as flexible as 6/4 or 5/5 — and is now moving toward full pilots with roughly 256 paid driver participants in each, targeting a 2027 launch, The Trucker reported August 27.

For a small carrier, this is not abstract rulemaking. The 14-hour clock is the reason a two-hour dock delay at 6 a.m. costs you your best delivery window at 6 p.m., and the reason your driver blows past cheap fuel and open parking at hour thirteen. If the pilots produce the data FMCSA is looking for, the flexibility drivers have begged for since the clock was invented could become regulation. There are three things to do about it this week: understand exactly what is being tested, get your name in front of the pilot if you want a seat, and — the part most fleets never do — start using the split-sleeper flexibility that is already legal today.

What FMCSA Is Actually Testing

The two programs were announced in September 2025 as part of Transportation Secretary Sean Duffy’s Pro Trucker Package, with Federal Register notices and a public comment window that closed last November, as Heavy Duty Trucking detailed at the time. The Split Duty Period pilot lets a driver pause the 14-hour window once a day, for 30 minutes up to three hours, using off-duty time, sleeper time, or on-duty-not-driving time — explicitly including detention at a shipper’s dock. The Flexible Sleeper Berth pilot goes further than the current rules by allowing rest splits of 6/4 or even 5/5, provided the two periods total at least 10 hours and one includes at least five consecutive hours in the berth. This spring and summer FMCSA quietly ran the pre-tests: nine drivers from three carriers per program, in states including Ohio, Wisconsin, Minnesota, and Virginia, each paid $600. With those complete, the agency is building toward the full four-month pilots — about 512 drivers in total, compensated up to $1,600, wearing sleep-tracking wrist devices and taking daily three-minute alertness tests while researchers compare their fatigue data against a baseline month under today’s rules. OOIDA has pushed for exactly this flexibility, with executive vice president Lewie Pugh telling Congress it would let tired drivers rest when needed instead of racing a clock.

Read the fine print the way an owner should: this is a study, not a rule. Nothing about your ELD changes this year, and a driver who pauses his 14-hour clock tomorrow without being enrolled in a pilot is running an illegal log — the same false-log violation that is now an automatic out-of-service trigger in the surprise blitzes we covered in the Any-Day Ready Drill. Make sure every driver on your roster hears that distinction this week, because the headlines alone will convince somebody the pause is already legal.

It is also fair to ask why this attempt should go anywhere when a similar split-duty pilot floated in 2020 and 2021 quietly died, as Trucking Dive noted when these programs launched. Two things are different this time. First, the political weight behind it: the pilots trace to an April 2025 executive order directing DOT to improve drivers’ working conditions, and they sit inside a named secretarial initiative rather than a staff-level study. Second, the design is built to survive scrutiny — a baseline month under today’s rules, then months under the test rules, with sleep measured by a device on the wrist instead of a survey, which is exactly the kind of evidence FMCSA has lacked every time safety advocates argued that flexibility just means a longer workday. Those advocates have not gone quiet, and they are right that a paused clock can stretch a duty day past sixteen hours of elapsed time. That fight will be waged with this pilot’s data, which is one more reason it matters whose trucks generate it.

How to Get a Seat in the Pilot

Roughly 512 seats across a population of hundreds of thousands of eligible CDL holders means the drivers who get in will mostly be the ones whose carriers raised a hand early. If you want your fleet represented — and there is a real case for it: your drivers get paid up to $1,600, you get first-hand operational experience with rules that may govern the next decade, and FMCSA gets data from actual small-carrier operations instead of only mega-fleet terminals — then move now. Register your interest through FMCSA’s hours-of-service pilot pages at fmcsa.dot.gov and watch the two Federal Register dockets from September 17, 2025 (documents 2025-17938 for split duty and 2025-17939 for the sleeper pilot) for the participation call, since that is where enrollment details will publish. Decide internally which drivers you would nominate: the pilot wants clean records and consistent ELD data, so put forward your steadiest hands, not your hardest runners. And brief the nominee honestly — the wrist actigraphy device, the daily vigilance tests, and the data sharing are conditions of the paycheck.

The Flexibility You Already Have — and Probably Don’t Use

Here is the part that can pay you this week, no pilot required. Since the 2020 revisions, the current sleeper berth provision already lets a driver split the 10-hour rest into 7/3 or 8/2 — at least seven hours in the berth paired with a second break of at least two hours, in either order — and, critically, neither qualifying period counts against the 14-hour window. Most small-fleet drivers have never once used it, because nobody ever walked them through what it buys. Walk through it with them: a driver gets loaded at 7 a.m. and faces a delivery appointment 620 miles away at 8 a.m. tomorrow. Run straight, and the 14-hour window forces him to shut down tonight at 9 p.m., short of the receiver, then fight morning traffic on a cold clock. Split it instead — drive the morning, take three off-duty hours through the afternoon rush, then finish the evening and take the seven-hour berth period within reach of the receiver — and the same legal hours land him rested at the dock while the straight-through driver is still hunting parking. The split is how you legally park during the hours when detention, traffic, and full truck stops are eating your day. If your drivers learn it now, a future 6/4 or 5/5 rule becomes an upgrade to a skill they already have instead of a novelty they misuse.

While you are re-teaching the split, re-teach the other 2020 flexibility most fleets forgot: the 30-minute break now only has to come after eight cumulative hours of driving, and an on-duty-not-driving period — fueling, a dock check-in, a trailer inspection — satisfies it. A driver who still parks the truck for a dedicated half-hour lunch because that is how he learned the rule in 2018 is donating thirty minutes of clock every single day. Across a five-day week that is two and a half hours of driving window handed back for nothing, which on your average lane is most of a load. Put both refreshers in the same tailgate talk: fifteen minutes with a whiteboard, one worked example each, and a rule that any driver planning a split calls dispatch first so the plan and the ELD agree.

The Pressure Trap: Who Really Gains From a Pause

Now the owner’s warning. A pause button on the 14-hour clock is worth real money to drivers stuck at a dock — and it is worth even more to the shippers who put them there. FMCSA itself has said it will watch for shippers, receivers, and carriers pressuring drivers to misuse the flexibility, and you can already write the script: if detention no longer burns the driver’s clock, the receiver who takes four hours to unload will feel even less urgency, and the broker will argue detention pay should start later because “the clock was paused anyway.” Do not let a safety study quietly reprice your dock time. Keep your detention terms exactly where they are — the Clause-Clock-Collect discipline charges for the driver’s time, not for his regulatory clock — and give every driver one clean sentence for the dock office that separates the two:

Train that line now, while the pause is still a pilot, and your rates will already be fenced off when the flexibility arrives for everyone.

Bottom Line

FMCSA has finished the dress rehearsal for the biggest hours-of-service change since 2020: a daily pause of up to three hours on the 14-hour clock and sleeper splits down to 5/5, headed for full pilots with paid seats in 2027. This week, do three things — tell your drivers the pause is not legal yet, register your interest with FMCSA if you want a seat and the data-collection strings that come with it, and teach the 7/3 and 8/2 splits your drivers can already run today. The carriers who treat the current rules as a toolbox instead of a cage will be the ones ready when the toolbox gets bigger.
