CVOR - Commercial Vehicle Operator’s Registration Hours of Service Compliance Questions and Answers

Question 1

According to Ontario's Hours of Service regulations, what is the maximum number of hours a commercial vehicle driver can drive in a day?

Accepted Answer

13 hours

Answer

Ontario Regulation 555/06 under the Highway Traffic Act states that a driver cannot drive more than 13 hours in a day. This is a core daily limit to prevent fatigue.

Question 2

A driver is operating under Cycle 1 (70 hours in 7 days). To reset this cycle and start a new one, what is the minimum required number of consecutive off-duty hours?

Accepted Answer

36 hours

Answer

To reset the 7-day cycle (Cycle 1), a driver must take at least 36 consecutive hours of off-duty time. This allows the 70-hour limit to start over.

Question 3

A driver begins their shift at 6:00 AM after 10 consecutive hours off-duty. They drive for 5 hours, are on-duty not driving for 4 hours, and take a 2-hour off-duty break. By what time must they stop driving to comply with the 16-hour elapsed time rule?

Accepted Answer

Midnight

Answer

A driver cannot drive after 16 hours have elapsed from the end of their most recent period of 8 or more consecutive hours off-duty. The 16-hour 'shift window' starts at 6:00 AM and ends at 10:00 PM (22:00). Regardless of the activities within the shift, driving is prohibited after this 16-hour window closes.

Question 4

Which of the following is a requirement for a driver operating on the 14-day (120-hour) cycle?

Accepted Answer

The driver must take at least 24 consecutive hours off-duty before accumulating 70 on-duty hours.

Answer

A specific rule for the 14-day cycle is that a driver shall not drive after accumulating 70 hours of on-duty time without having taken at least 24 consecutive hours of off-duty time. A full reset of the 14-day cycle requires 72 hours off-duty.

Question 5

A driver encounters an unforeseen blizzard which closes the highway, delaying their trip. Under the 'adverse driving conditions' provision, by how much can they extend their maximum permitted driving and on-duty time to complete the trip safely?

Accepted Answer

Up to 2 hours

Answer

If a trip could have been completed in the normal time but is delayed by unforeseen adverse driving conditions (like a sudden storm or accident), the driver may extend their total driving and on-duty time by up to 2 hours to reach a safe destination. This provision cannot be used for predictable delays like regular rush hour traffic.
