No account, no upload, no tracking: every calculation runs in your browser and nothing you type leaves this page.
This is an educational calculator, not an ELD, not legal advice, and not an official FMCSA compliance determination.
Enter the two rest periods exactly as they are logged. The tool checks whether they pair as a split sleeper berth break, shows every condition it tested, and says plainly when it cannot answer.
Nothing has been checked yet. Fill in the two rest periods above, or load one of the worked examples, and the verdict, the condition-by-condition read-out and the log strip appear here.
For property-carrying drivers, the generally applicable sleeper berth provision splits the required 10 hours of rest into two periods. One period must be at least 2 h off duty or in the sleeper berth. The other must be at least 7 h of consecutive time in the sleeper berth. Together they must total at least 10 h. FMCSA states that when the two qualifying periods are used together, neither of them counts against the maximum 14-hour driving window.
The surrounding limits are the ones this calculator measures against: a property-carrying driver may drive up to 11 h after 10 consecutive hours off duty, and may not drive beyond the 14 h point measured from coming on duty after that rest.
FMCSA guidance effective 2026-07-01 says a qualifying 10-consecutive-hour rest that includes at least 7 h of consecutive sleeper berth time may either restart the 11-hour and 14-hour limits or be paired with a later qualifying period of at least 2 h. The driver may use whichever treatment is allowable and more advantageous. Because both readings are open, this calculator evaluates them as separate branches and lists every branch it found rather than quietly choosing one.
A companion guidance item, also effective 2026-07-01, confirms that a 3-hour off-duty period may pair with a later 10-consecutive-hour sleeper berth period, and that the 3-hour period then does not count against the 14-hour window. That shape is one of the worked examples below.
The 6/4 and 5/5 alternatives are limited 2026 Flexible Sleeper Berth pilot options for approved test participants. They are not ordinary options for ordinary drivers, so this calculator does not present them, does not accept them as a mode, and will not report a 6-and-4 or 5-and-5 pattern as qualifying.
This is an educational calculator, not an ELD, not legal advice, and not an official FMCSA compliance determination.
Each figure below is produced by the same rule engine the calculator uses, so what you read here is what the tool will say. Load any example to see the full read-out and log strip.
7 hours in the sleeper berth, then 3 hours off duty later the same day.
Qualifies: 1 qualifying treatment found for these two rest periods.
Remaining hours are not quantified for this example.
The sleeper berth leg carries the 7 consecutive hours and the off-duty leg carries the rest of the 10-hour total.
2 hours off duty first, then 8 hours in the sleeper berth.
Qualifies: 1 qualifying treatment found for these two rest periods.
Remaining hours are not quantified for this example.
The order of the two legs does not change the check. The shorter leg only has to reach 2 hours.
The FMCSA FAQ07 shape: a 3-hour off-duty period followed by a 10-consecutive-hour sleeper berth period, with 5 hours of driving and 1 hour of other on-duty time after it.
Qualifies: 2 qualifying treatments found for these two rest periods.
With the reported work totals, driving still allowed once both limits apply: 6 h.
The 10-hour sleeper period qualifies twice over, so the reset treatment and the pairing treatment both stay on the table. Only the reset treatment has a documented restart point, so that is the one this tool can quantify.
6 hours in the sleeper berth and 4 hours off duty, 10 hours in total.
Does not qualify: These two rest periods do not qualify as a split under the ordinary sleeper berth rule.
Remaining hours are not quantified for this example.
The total reaches 10 hours but no leg reaches 7 consecutive sleeper berth hours, so nothing qualifies. A 6-and-4 pattern is a limited pilot option, not an ordinary one.
Every rule statement on this page traces to one of these four FMCSA pages, reviewed on 2026-08-25. Nothing here is sourced from a competitor tool, a forum answer or a model summary.
All arithmetic is whole minutes, so a period of 6 hours 59 minutes never rounds up into a qualifying 7-hour leg. The rule engine has no clock, no locale, no randomness and no network access; the same input always produces the same output. Where the cited FMCSA pages do not state a deterministic answer, the tool returns a not-enough-information state with the reason, instead of inventing arithmetic. That is why a valid pairing can still show no remaining-hours figure.
The rule text behind this build was reviewed against the four cited FMCSA pages on 2026-08-25, and each source carries its own publication marker above so you can see how fresh it is. Rule changes are applied by re-reading the primary sources and re-running the test suite; the calculator is not updated from secondary commentary. If a source has moved on since the date shown, treat the page as stale and read the FMCSA source directly.
Under the generally applicable sleeper berth provision a property-carrying driver needs one period of at least 2 hours off duty or in the sleeper berth and another period of at least 7 consecutive hours in the sleeper berth, and the two together must total at least 10 hours.
FMCSA states that when the two qualifying periods are used together, neither of them counts against the maximum 14-hour driving window. This calculator repeats that statement and shows which two periods it applied it to.
No. The 6/4 and 5/5 alternatives are limited 2026 Flexible Sleeper Berth pilot options for approved test participants. They are not ordinary options, this calculator does not offer them, and it will not treat a 6-and-4 or 5-and-5 pattern as qualifying.
FMCSA guidance effective 2026-07-01 says a qualifying 10-consecutive-hour rest that includes at least 7 consecutive sleeper berth hours may either reset the 11-hour and 14-hour limits or be paired with a later qualifying period of at least 2 hours, whichever the driver finds more advantageous. This calculator keeps both treatments visible instead of picking one silently.
The FMCSA pages this build cites state an explicit restart for a qualifying 10-hour rest but do not state where the 11-hour and 14-hour clocks restart after a paired split. Rather than invent that arithmetic, the tool reports that the pairing check is available and that remaining hours need a complete ELD or paper-log review.
No. It is a reading aid for two rest periods you type in. It is not an electronic logging device, it has no GPS or vehicle connection, it is not legal advice, and it does not decide whether you or your carrier are in compliance.
No. There is no account, no upload and no tracking. The rule engine is plain arithmetic that runs in your browser, and closing the tab discards everything you entered.
No account, no upload, no tracking: every calculation runs in your browser and nothing you type leaves this page. There is no sign-up, no payment, no advertising, no analytics script and no third-party embed. The page is a static bundle: the HTML, the stylesheet, the script and the two typefaces all come from this domain, and the calculator keeps working with the network disconnected.
The tool never asks for a driver name, a truck number, a carrier, a location or a licence number, and it has no connection to a vehicle, a GPS receiver or an electronic logging device. What you type stays in the browser tab and is gone when you close it.
