Hours of Service Practice for Truck Dispatchers
Hours-of-service rules limit how long a commercial driver may drive and work before rest is required, which makes them the capacity constraint on every commitment a dispatcher makes. Before accepting freight a dispatcher checks driving hours available today, on-duty hours, hours remaining in the cycle, the realistic time the trip needs including loading and fuelling, and where the driver will legally park when the clock runs out. Hours-of-service requirements differ between Canada and the United States and change over time; verify current rules with the relevant regulator.
- Check driving hours, on-duty hours and cycle hours before booking
- Plan realistic trip time: driving plus loading, fuelling, inspections, border and traffic
- Confirm the driver will have safe, legal parking when hours expire
- Prefer destinations where a rested driver can reload
- Never resolve a delay by pressuring a driver past legal hours
Example: an appointment that does not fit
A 06:00 pickup 520 miles away needs roughly 10.5 hours of driving at a 50 mph planning average, and about 12 hours of clock once fuelling, a pre-trip and a break are added. If the driver finished a delivery at 15:00 with limited hours left, rest is required first, so arrival falls past the appointment. The correct responses are to negotiate a later appointment, offer another truck, or decline.
Common mistakes
Hours-of-service failures are usually planning failures.
- Planning on map driving time only
- Counting driving hours but not on-duty hours
- Fitting today's load while breaking the week's cycle
- Running a driver out of hours where there is no safe parking
- Failing to warn the receiver early when delivery will be late
Frequently asked questions
Why do dispatchers need to understand hours of service?
Driver hours determine whether an appointment can be met legally. Booking without checking remaining driving and on-duty time creates late loads, unsafe pressure on drivers and compliance risk for the carrier.
What should a dispatcher check before dispatching a load?
Remaining driving hours, remaining on-duty hours, hours left in the cycle, realistic trip time including loading and fuelling, and where the driver will legally park when hours run out.
Are Canadian and US hours-of-service rules the same?
No, they differ and both change over time, so requirements should be verified with the relevant regulator rather than assumed.
