Hours of Service Rules for Truck Dispatchers in Canada and the U.S.
A load pays well, the truck is close, and pickup is available in an hour. Dispatch is ready to accept it until the driver’s log shows how many hours the driver has already worked. The driver can reach the shipper. Whether the driver can make the delivery is less certain.
Hours of Service (HOS) regulations limit when commercial drivers may drive based on their driving and on-duty hours, and require off-duty periods. Dispatchers encounter those limits when assigning freight or agreeing to an appointment. The distance shown on a load board doesn’t account for hours the driver spent at a warehouse that morning or show when the driver must stop.
Canada and the U.S. have separate regulatory frameworks. Cross-border schedules have to account for the requirements on each side, using the driver’s recorded hours rather than a fresh estimate at the border.
What HOS Rules Mean for Truck Dispatchers
Duty status shows whether the driver is driving, doing other on-duty work, or off duty. Two hours spent loading at a dock can use up two hours of the work window without using any driving hours. Dispatch also has to check the current shift and the hours accumulated over previous days.
A driver starts at 6 a.m. At noon, a shipper offers a load that must be delivered by 5 p.m. Loading usually takes 30 minutes, but the dock is running two hours behind. Dispatch asks when the trailer will be ready and checks the driver’s remaining driving hours and work window. If loading won’t finish until 2 p.m., dispatch checks whether the receiver will accept a later arrival or assigns the load to another driver.
U.S. vs Canada Hours of Service Rules
The two countries use different daily limits and different limits on how long a driver can drive during a shift. For dispatch, that means checking the driver’s recorded hours against the rules for each side of a cross-border trip, not carrying one set of numbers across the border.
U.S. Hours of Service Rules
Under the federal FMCSA hours of service rules for property-carrying commercial drivers, a driver may drive up to 11 hours after 10 consecutive hours off duty. Driving must fit within a 14-hour window after coming on duty. After eight cumulative hours of driving without a qualifying interruption, the driver must take a 30-minute break. Driving is also prohibited after 60 on-duty hours in seven consecutive days or 70 in eight consecutive days, according to the carrier’s operating schedule.
Waiting at a dock ordinarily doesn’t pause the 14-hour clock. If loading runs late, the driver may still have driving hours remaining but too little of the window left to reach the next stop.
Canada Hours of Service Rules
For federally regulated operations south of 60°N, a driver cannot drive after accumulating 13 hours of driving or 14 hours on duty in a day. The rules require at least 10 hours off duty in a day and prohibit driving after 16 hours have elapsed since the end of the last qualifying period of at least eight consecutive hours off duty.
Canada has two duty cycles: 70 on-duty hours in seven days and 120 on-duty hours in 14 days. Under the 14-day cycle, a driver also cannot drive after accumulating 70 on-duty hours without taking 24 consecutive hours off duty. Those totals include hours worked on earlier trips, before the load currently being considered.
Why the Difference Matters for Cross-Border Dispatch
A driver leaves the Toronto area with a delivery appointment in Michigan. Loading takes longer than expected, and the truck waits another two hours at the border. Dispatch checks the driver’s full log against U.S. limits, then calls the receiver with an arrival time the driver can legally meet.
How HOS Affects Load Planning and Dispatch Decisions
HOS load planning begins before dispatch accepts the load. Loaded miles cover only the trip from the shipper to the receiver. The driver must first reach the pickup, wait for the freight, and still have enough time available to make the delivery appointment.
Consider a driver finishing an unload across town. A new shipper offers a pickup at 3 p.m., but the driver won’t be released from the receiver until 2. The driver still has to travel across town, account for traffic, and wait for loading. Dispatch should ask when the driver will finish unloading and whether the shipper will hold the pickup slot. If the freight is going across the border, the delivery plan must also allow for the crossing and any required rest before the next leg.
Available driving hours aren’t the same as the time left in a work period. A driver may still have driving hours remaining while approaching the end of the permitted window. Dispatch checks the log against the proposed appointments and, if the schedule doesn’t fit, requests another slot or assigns a different driver.
ELDs, HOS Tracking, and Driver Availability
An Electronic Logging Device (ELD) connects to the truck’s engine to record driving time and helps maintain the driver’s duty-status log. Dispatch can review the hours already recorded, including when the driver is approaching a required rest period. The device records activity; it does not change the legal driving limits.
What Dispatchers Use HOS Data For
Recorded hours help narrow the choice of drivers when several pickups are due. The ELD does not show when a truck waiting at a receiver will finish unloading. Dispatch checks that with the driver before offering the truck for its next load.
Common HOS Planning Mistakes Dispatchers Need to Recognize
One common error is assigning a load based only on the driving hours shown on a screen. The truck still has to reach pickup, wait for freight, and arrive within the receiver’s appointment window.
A dispatcher may accept a delivery slot while the driver is still unloading the previous shipment. By the time that trailer is empty, the driver may arrive at the next pickup later than the mileage estimate suggests. Assuming a live load will take 30 minutes creates the same problem when trucks are already lined up at the shipper.
A border delay can put delivery beyond the receiver’s operating hours. Canadian and U.S. driving limits also differ, so dispatch must check the rules that apply to each part of the trip. An ELD shows recorded hours but does not account for the receiver’s closing time or the current border queue.
Learning HOS as Part of Truck Dispatcher Training
Knowing the basic FMCSA and Canadian hours-of-service rules helps a dispatcher recognize when a proposed trip needs closer review. Truck dispatching also involves load selection, route planning, driver communication, and rate negotiation. The appointment details provided by a broker, a carrier’s logbook, and customs paperwork for a cross-border load all affect how the shipment is planned.
In our truck dispatcher training course, participants cover Hours of Service, ELDs, and logbooks for both Canada and the U.S. They also work with a live load board, learn load matching and rate negotiation, and use dispatching, brokerage, and transportation management software. The course includes border-crossing procedures and ACE/ACI eManifest exercises, so participants see how driver availability connects with the documents and systems behind a cross-border shipment.
Frequently Asked Questions
How do Canadian hours of service affect a driver near the end of a busy week?
The current day’s log is only part of the check. A Canadian driver following cycle 1 cannot drive after accumulating 70 hours of on-duty time in seven days. Cycle 2 has a 120-hour limit over 14 days, plus a restriction at 70 hours unless the driver has taken 24 consecutive hours off duty. Before assigning another long run, the motor carrier needs the driver’s cycle total, not just the hours available after the last rest period.
Does time in a sleeper berth automatically make a driver available again?
No. Sleeper berth provisions allow certain qualifying rest periods to be split, but time spent there is not an automatic reset of all driver hours. Under the U.S. property-carrying provision, one period must include at least seven consecutive hours in the berth, another must last at least two hours, and the two periods must total at least ten hours. Canadian provisions have their own requirements. Dispatch should use the driver’s recorded status and the applicable rules before assigning the next movement.
What should dispatch check under federal hours of service before accepting a U.S. pickup?
For a property-carrying driver, check the remaining driving allowance, the 14-hour driving window, whether a 30-minute break is due, and the applicable seven- or eight-day on-duty total. Those limits answer different questions. A driver can have driving hours unused while nearing the end of the window in which driving is permitted. The proposed trip also includes travel to the shipper and any wait before loading, so an open pickup slot by itself does not establish availability.
When do provincial hours of service apply in Canada?
Provincial rules generally govern carriers that operate only within a province. Carriers that transport goods across provincial or international borders fall under federal regulation, even when a particular trip stays within one province. For dispatch, the carrier’s operation is the starting point, not just the route on today’s load board. A company handling both local and cross-border freight should confirm which rules govern its drivers before setting schedules.
Do Canadian hours of service rules measure a day and a work shift the same way?
No. For federally regulated trips south of 60°N, the rules include daily limits on driving and on-duty time, as well as a separate elapsed-time limit tied to the driver’s last qualifying off-duty period. A driver who stops working partway through a shift has not necessarily paused that elapsed-time clock. For dispatch, the useful question is which limit will restrict the next leg first. The answer depends on the full log, not a single remaining-hours figure.
