Who must comply

  • Hours-of-service rules (O. Reg. 555/06) apply to drivers of commercial motor vehicles over 4,500 kg gross or registered gross weight, and to buses, school buses and school-purposes buses.
  • Exempt examples: commercial vehicles (other than buses) of 4,500 kg or less, vehicles leased by an individual for 30 days or less, tow trucks, motor homes, ambulances, fire apparatus, police and emergency-relief vehicles, and personal-use pick-ups with an MGVWR of 6,000 kg or less.
  • Two- or three-axle vehicles carrying primary farm, forest, sea or lake products are also exempt.

Duty status

  • There are four duty statuses: off duty (not in a sleeper berth), off duty in a sleeper berth, on duty driving, and on duty not driving.
  • On-duty time includes inspecting, cleaning or repairing the vehicle, loading and unloading, riding as a co-driver (not in the berth), and waiting at inspections, for loading or after a collision.

Daily limits

  • A driver must have 10 hours off duty in a day.
  • A driver may not drive more than 13 hours in a day, and may not drive after 14 hours on duty in a day.
  • After at least 8 consecutive hours off duty, a driver may not drive more than 13 hours, may not drive after 14 hours on duty, and may not drive once 16 hours have passed.

Cycles

  • The operator assigns either a 7-day or a 14-day cycle.
  • 7-day cycle: no driving after 70 hours on duty in 7 consecutive days.
  • 14-day cycle: no driving after 120 hours on duty in 14 consecutive days, and no driving after 70 hours on duty without having taken 24 consecutive hours off.
  • Every driver must have had at least 24 consecutive hours off duty in the preceding 14 days.
  • To reset or switch cycle: 36 consecutive hours off on the 7-day cycle, 72 consecutive hours off on the 14-day cycle.

Daily log

  • A daily log can be handwritten, computer-generated or made by a recording device.
  • It must show the driver and co-drivers, date, start time if not midnight, cycle, odometer at start and end, plates of each vehicle and trailer, operator name, home terminal and principal place of business, start and end of each duty status and where it changed, total time in each status, total distance and the driver's signature.
  • The graph grid (Form 1) is not required when a recording device is used.
  • No log is needed if the driver stays within 160 km of the starting location, returns there at the end of the day and works for only one operator that day; the operator then keeps a record of the day.
  • Drivers carry the log for the current day and the previous 14 days.
