Hours of Service and Driver Fatigue Management
What this domain tests
Quebec applies the federal Commercial Vehicle Drivers Hours of Service Regulations. The exam tests the arithmetic of the limits, the structure of the daily log, and whether you can recognise and manage fatigue rather than just count hours.
The limits
- Maximum 13 hours driving, 14 hours on duty, and 16 hours elapsed from the end of your last 8 consecutive hours off duty.
- At least 10 hours off duty in each day, of which at least 8 must be consecutive.
- Cycle 1: no driving after 70 hours on duty in 7 days; reset with 36 consecutive hours off.
- Cycle 2: no driving after 120 hours on duty in 14 days; reset with 72 consecutive hours off, and at least 24 consecutive hours off in the preceding 14 days.
- Carry the current day's log plus the previous 14 days. Most federally regulated carriers must use a certified electronic logging device.
- Neither a carrier nor a shipper can require you to exceed the limits.
Fatigue management beyond the numbers
The highest-risk window for a long-haul driver is roughly 02:00 to 06:00, and again mid-afternoon. Warning signs: lane drift, missing a sign you just read, heavy eyelids, yawning, wandering thoughts. A 15-20 minute nap, fresh air, a short walk and caffeine work; loud music and an open window do not. Sleep debt accumulates - two short nights are not erased by one long one.
Worked example
You start at 05:00 after 9 hours off. By 15:00 you have driven 6 hours and been on duty 8. That leaves 7 hours of driving and 6 hours of on-duty time, and the 16-hour elapsed limit does not expire until 21:00. On-duty time binds you first, at 19:00, so plan the stop before 19:00, not at the driving limit.
Traps that cost marks
Counting loading, fuelling and inspection time as off duty; assuming a 24-hour break resets Cycle 2; and treating "I feel fine" as a defence for an over-limit log.
