HOS Rules for Dispatchers in 2026: 11/14/70 Explained for US & Canada

For dispatchers, owner‑operators, and carriers, Hours of Service (HOS) compliance isn’t just a box‑check exercise – it’s the engine that powers reliable pickups, on‑time deliveries, and driver satisfaction. In 2026 the core limits remain the same, but newer ELD firmware, real‑time traffic data, and tighter FMCSA enforcement mean you must plan every load with the 11/14/70 framework (US) or the 13/14/70 framework (Canada) front‑and‑center.

US HOS Rules You Must Build Into Every Load

• **11‑Hour Driving Limit** – After a minimum 10‑hour off‑duty period, a driver may log up to 11 hours of driving. The clock runs only while the vehicle is moving; any off‑duty or sleeper time pauses the count.
• **14‑Hour On‑Duty Window** – The 14‑hour clock starts the moment the driver reports for duty following those 10 off‑duty hours. It includes driving, loading, paperwork, detention, and any other on‑duty activity. Once the 14‑hour window closes, the driver must stop driving even if the 11‑hour limit isn’t reached.
• **30‑Minute Break** – Within the first 8 hours of the on‑duty window, drivers must take a 30‑minute break that can be off‑duty or in the sleeper berth. Dispatchers should always schedule a buffer for this break when you book a dock appointment.
• **10‑Hour Off‑Duty Reset** – A fresh 14‑hour window can’t begin until the driver has accumulated at least 10 consecutive off‑duty hours. This reset is non‑negotiable.
• **60/70‑Hour Weekly Cycle** – Drivers may not be on duty for more than 60 hours in any 7‑day period or 70 hours in any 8‑day period. A 34‑hour off‑duty break (often called the “reset”) clears the cycle and starts a new 7‑day count.
• **Sleeper‑Berth Split** – The 10‑hour off‑duty can be split into two periods: one of at least 7 consecutive hours in the sleeper berth and a second of at least 2 hours (off‑duty or sleeper). Neither segment counts toward the 14‑hour on‑duty window, giving you flexibility on long hauls.
• **Adverse‑Condition Extension** – If severe weather or an unexpected traffic incident forces a driver to stop, the FMCSA permits up to a 2‑hour extension of the 11‑hour driving limit and the 14‑hour window. Treat this as a safety net, not a planning tool.
• **Short‑Haul Exemption (150‑Air‑Mile)** – Drivers staying within a 150‑air‑mile radius of their normal reporting location and returning within the same 14‑hour window are exempt from the 30‑minute break and the 10‑hour off‑duty requirement, but they still must obey the 14‑hour and 60/70‑hour limits. This exemption is common for LTL and regional runs.

Dispatch Takeaway: When you pull a load from DAT, Truckstop, or Loadlink, plug the estimated drive time into a spreadsheet that also subtracts 30 minutes for the break, adds any expected detention, and then checks the remaining on‑duty allowance. If the total exceeds 14 hours, either split the load, add a layover, or assign a different driver.

Canadian HOS Rules (Transport Canada) – What’s Different?

Canada’s rules are similar enough to cause confusion, but the key differences give you a few extra minutes of mileage:

• **13‑Hour Driving Limit** – Drivers may drive up to 13 hours after a minimum 8‑hour off‑duty period. This extra two hours can be the difference between a cross‑province run and a missed delivery.
• **14‑Hour On‑Duty Limit** – Identical to the U.S., the total on‑duty time (driving, loading, paperwork, detention) cannot exceed 14 hours.
• **16‑Hour Elapsed‑Time Cap** – From the moment a driver starts the day (after the 8‑hour off‑duty), a hard 16‑hour cap applies regardless of on‑duty status. This prevents drivers from stretching the day with long off‑duty breaks.
• **8‑Hour Off‑Duty Minimum** – Drivers need at least 8 consecutive off‑duty hours each day, with a minimum of 30 minutes of that time taken in 30‑minute blocks. Two of those hours must be consecutive, which aligns with most sleeper‑berth practices.
• **70‑Hour / 120‑Hour Cycles** – Cycle 1 mirrors the U.S. 70‑hour in 8‑day limit, requiring 36 consecutive hours off to reset. Cycle 2 allows up to 120 hours over 14 days but needs a 72‑hour reset. Most carriers operate under Cycle 1 because the longer reset is rarely practical.

Dispatch Takeaway: When you schedule a Canada‑only load, add a 2‑hour cushion to the U.S. drive‑time estimate to account for the higher daily driving limit, but still watch the 14‑hour on‑duty window. If you’re crossing the border, you must obey the stricter of the two regimes for the portion of the trip that falls under each jurisdiction.

How to Build HOS Checks Into Your Dispatch Workflow

1. Integrate ELD Data – Modern ELDs push real‑time logs to cloud dashboards. Set up an API feed that flags any driver approaching the 11‑hour or 14‑hour thresholds. Most dispatch platforms already have this feature; if yours doesn’t, a simple webhook can push alerts to Slack or Teams. 2. Pre‑Load Calculation Sheet – Create a master spreadsheet with columns for: - Load ID (DAT, Truckstop, etc.) - Estimated drive time (including traffic factor) - Planned break (30 min) - Expected detention / layover - Total on‑duty time - Remaining hours in driver’s current cycle 3. Dynamic Routing Software – Use routing tools that ingest live traffic, weather, and weigh‑station delays. The software should automatically subtract the 30‑minute break and flag any route that pushes the driver past the 14‑hour limit. 4. Weekly Cycle Tracker – Maintain a rolling 7‑day (U.S.) or 8‑day (Canada) log that updates each time a driver logs off. Highlight drivers who are within 5 hours of the 70‑hour cap so you can proactively assign off‑day blocks. 5. Communication Protocol – Require drivers to confirm receipt of the planned break and any detention expectations before they sign off on a load. A simple “ACK” message in your dispatch chat eliminates surprises.

Managing Accessorials Without Violating HOS

Accessorials—detention, layovers, TONU (Truck Ordered Not Used), and other fees—are revenue generators, but they also eat into the driver’s on‑duty window.

• **Detention**: If a driver is held longer than the free‑time window at a shipper/receiver, add the detention minutes to the on‑duty total. Some carriers treat detention as “off‑duty” for HOS purposes only if the driver is physically able to rest; otherwise, it counts toward the 14‑hour window.
• **Layover**: A layover that exceeds the driver’s scheduled off‑duty period must be logged as on‑duty. Plan layovers in advance and, when possible, negotiate a paid layover that includes a rest period for the driver.
• **TONU**: Even if the load is cancelled, the driver’s time up to the cancellation point counts as on‑duty. Keep TONU events separate in your tracker so you can bill the shipper while still respecting HOS.
• **Quick‑Pay & Factoring**: When you use a factoring company, the payment cycle often forces you to accelerate load acceptance. Resist the urge to stack loads back‑to‑back without checking the driver’s remaining on‑duty time.

By treating each accessorial as a line item in your HOS spreadsheet, you avoid the “forgot‑the‑detention” surprise that lands you in an FMCSA audit.

Training Your Team for HOS Success

Even the best software fails if the people using it don’t understand the rules. A short, focused training session should cover:

• The difference between *driving* hours and *on‑duty* hours.
• How sleeper‑berth splits work and when they are permissible.
• The impact of short‑haul exemptions on load planning.
• Real‑world case studies of violations that cost carriers $10‑$20 K in fines.

EK Dispatch Academy’s latest simulator module walks you through a full week of dispatch decisions, flagging HOS violations before they happen. It’s a fast way to turn theory into practice.

Quick Checklist for Every Load

• [ ] Verify driver’s current 11‑hour/14‑hour balance via ELD.
• [ ] Add a 30‑minute break if the driver is within the first 8 hours.
• [ ] Include estimated detention and layover time in the on‑duty total.
• [ ] Confirm the driver’s weekly 70‑hour status.
• [ ] Apply the short‑haul exemption only when the 150‑air‑mile rule truly applies.
• [ ] Document any adverse‑condition extensions and notify compliance.

Following this checklist reduces the risk of out‑of‑service orders and protects your carrier’s MC/NSC rating.

Frequently asked questions

Q: How do I know if a driver is close to the 70‑hour weekly limit? A: Most ELD dashboards show a “weekly hours used” bar. Set an alert for 65 hours so you have a 5‑hour safety margin before the limit is reached.

Q: Can I use the 2‑hour adverse‑condition extension for regular traffic delays? A: No. The extension is only for truly unforeseen conditions like severe weather or major accidents. Relying on it for routine congestion can lead to violations.

Q: What should I do if a driver hits the 14‑hour on‑duty window while still loading a trailer? A: The driver must stop work, secure the load, and either wait for off‑duty time or arrange a layover. The load can be reassigned to another driver who has sufficient HOS balance.
