Hours of Service (HOS) Compliance Essentials for Truckers

If you run your own authority or a small fleet, Hours of Service (HOS) rules are not just a roadside-inspection headache. Every logbook violation feeds your CSA score, and that score is the same number your insurer prices off and your lender pulls when you apply for a truck loan. Clean logs are, in a very real sense, working capital.

This guide walks through the current federal HOS rules for property-carrying drivers as they stand in 2026, then connects the dots to the cost of money in your business. The core limits below have been in effect since 29/09/2020 and have not changed since, but Washington runs the occasional pilot program, so we flag what is settled rule versus what is still being tested.

The core HOS limits

For property-carrying commercial drivers, the FMCSA Hours of Service summary sets four limits you have to track at once:

• 11-hour driving limit. You may drive a maximum of 11 hours after 10 consecutive hours off duty.
• 14-hour limit. You cannot drive beyond the 14th consecutive hour after coming on duty, following 10 hours off. Note this is a clock, not a tank — breaks, fueling, and loading time burn the 14-hour window even though you are not driving. Once it expires, you are parked until you take another 10 off.
• 30-minute driving break. After 8 cumulative hours of driving without a break of at least 30 minutes, you must take one. It can be off duty, in the sleeper berth, or on duty not driving — what matters is that you are not driving for 30 straight minutes.
• 60/70-hour limit. You cannot drive after 60 hours on duty in 7 consecutive days, or 70 hours in 8 consecutive days. Which one applies depends on whether your operation runs every day of the week (70/8) or not (60/7).

The 34-hour restart

You reset that weekly 60- or 70-hour clock with a 34-hour restart — 34 or more consecutive hours off duty. The old requirement that a restart include two 1:00 a.m.–5:00 a.m. periods and be limited to once per week was removed years ago, so today any 34 consecutive off-duty hours qualifies, with no time-of-day or frequency restriction.

Sleeper berth, short-haul, and adverse conditions

Three provisions give you flexibility — used correctly, they keep you legal on long runs.

Sleeper-berth split. You can split the required 10 hours off into two qualifying periods. Per FMCSA's split sleeper-berth guidance, the legal splits are 8/2 or 7/3: one period of at least 7 consecutive hours in the sleeper berth, paired with a second period of at least 2 consecutive hours (off duty or in the berth), as long as the two add up to at least 10 hours. Neither period counts against your 14-hour window.

Short-haul exception. If you stay within a 150 air-mile radius of your reporting location, return there, and finish your day within 14 hours, you can use the short-haul exception (CDL drivers). Qualifying drivers do not need to keep records of duty status, run an ELD, or take the 30-minute break. Non-CDL drivers get a 100 air-mile radius and a 12-hour limit instead. Break any condition — exceed the radius or blow the time limit — and the full HOS rules, including ELD logging, apply retroactively for that day.

Adverse driving conditions. When unexpected weather or traffic you could not have known about slows you down, you may extend both the 11-hour driving limit and the 14-hour window by up to 2 hours. It does not cover routine congestion you should have planned around.

One thing to watch in 2026: FMCSA has a pilot program testing a 30-minute-to-3-hour pause of the 14-hour window. That is a study, not a rule — do not log against it unless you are an enrolled participant and FMCSA confirms your eligibility.

ELD requirements

Most interstate drivers who keep records of duty status must run a registered electronic logging device (ELD). The notable carve-outs, per FMCSA's ELD compliance rules, are:

• Drivers using the short-haul exception described above.
• Drivers who keep RODS no more than 8 days in any 30-day period.
• Vehicles with an engine model year older than 2000 (the engine, not the truck body).
• Drive-away/tow-away operations where the vehicle is the commodity.

If you do not clearly fit a carve-out, assume you need a compliant ELD. "My truck is old" only works if the engine predates model-year 2000.

Why HOS compliance is a financing issue

Here is the part most logbook guides skip. HOS violations are recorded in the HOS Compliance BASIC of the FMCSA's Safety Measurement System, and they push up your CSA score. Insurers price almost directly off that score: carriers with poor safety records pay higher premiums, get less flexible terms, and in bad cases get pushed out of standard markets into surplus lines, according to industry insurers.

That matters for your balance sheet two ways. First, a higher premium is a recurring cost that drags your net margins — and if you finance those premiums, a worse rate compounds it (see our insurance financing guide). Second, lenders and brokers increasingly inspect carrier safety profiles. A clean HOS record signals an operator who runs a disciplined business, which is exactly the borrower equipment lenders want. A bad one can mean a higher rate, a larger down payment, or a flat decline.

The practical takeaway: treat your ELD logs like your books. Audit them, fix recurring violation patterns, and dispute inspection errors through DataQs. Tight compliance is one of the cheapest ways to protect both your insurance rate and your access to capital.

Bottom line

The HOS math is fixed — 11 driving, 14 on-duty, a 30-minute break, 60/70 weekly, and a 34-hour restart — with sleeper-berth, short-haul, and adverse-conditions flexibility around the edges, all logged on an ELD unless you qualify for a carve-out. Run those numbers cleanly and you protect more than your CDL: you protect the insurance and financing terms that keep your truck on the road.
