Hours of Service Flexibility Is Headed for 2027 and Your Logs Will Still Decide Claims

FMCSA finished the last step before the real pilots

The Federal Motor Carrier Safety Administration published an update on August 27 on the two hours of service pilot programs it has been building since September 2025, and the headline is that the pre-tests are finished. Heavy Duty Trucking, which publishes as Trucking Info, reported the update, and Land Line covered the same milestone. Pre-tests are the dry run. The agency used them to check its procedures, its data collection, and what it will ask of participating drivers before opening the programs to a much larger group next year.

Those dry runs were small on purpose. The Flexible Sleeper Berth pre-test ran April 1 through June 11 of this year with nine drivers from three motor carriers in Ohio, Virginia, and Wisconsin. The Split Duty Period pre-test ran May 18 through July 17 with nine drivers from three carriers in Minnesota, Wisconsin, and Ohio. Each driver ran six weeks and was paid $600. The full programs land in 2027 with 256 drivers apiece, 512 in total, running four months for up to $1,600.

What the two pilots would actually change

The Flexible Sleeper Berth pilot tests letting a driver break the required ten hours into two periods in any combination, so long as the two add up to at least ten hours and one of them is at least five consecutive hours in the sleeper berth. The split options on the books today are far more rigid than that, and anyone who has tried to time rest around a dock appointment knows what that rigidity costs.

The Split Duty Period pilot is the one most owner-operators will care about. It tests pausing the 14 hour driving window for up to three hours a day when the driver is in a qualifying non driving status. That can be off duty time, sleeper berth time, or on duty time at a pickup or delivery location. In plain terms, a three hour wait at a shipper would stop eating the clock.

Your log is the first document an adjuster pulls

Here is why a rulemaking pilot belongs on an insurance site. When a truck is in a serious crash, the electronic log is one of the earliest records anyone asks for, your own carrier included and the other side's attorney right behind it. It lays out how long the driver had been working, where the last rest period fell, and whether the run was legal. That timeline shapes how a commercial auto liability claim gets defended long before anybody argues about skid marks.

Flexibility cuts both ways there. A driver who can pause the clock for three hours at a dock is a driver who can take real rest instead of racing a deadline, and a rested driver is a cheaper driver to insure. A more complicated ruleset also hands a plaintiff attorney more places to argue the log was gamed. Whatever comes out of the pilots, clean and consistent records are the asset.

Flexibility does not move the risk off your policy

None of this changes who pays. Federal minimum liability filings, your own limits, and the way an underwriter reads your record all stay exactly where they are. What changes is the shape of the day. If a pilot participant runs a split duty period and then has an incident during the paused window, the argument becomes one about duty status and how the truck was being used, and duty status is the very line that non-trucking liability coverage turns on. If you ever sign up for one of these programs, tell your agent before the first load rather than after the first claim.

What a small fleet should do between now and 2027

Nothing here is mandatory and nothing takes effect this year, so the useful work right now is the boring work. Audit your log edits and your unassigned driving time, because those two things are what read as sloppy in a deposition. Look at where your operation actually loses hours, at the docks or on the rest split, so you know which pilot would help you if it ever becomes a real rule. And find out what your record is costing you today, since fatigue related violations feed the CSA scores underwriters price against. Our guide to what commercial truck insurance costs walks through those inputs one by one.
