2Which of the following vehicles are you permitted to drive with a valid Ontario Class C licence?
A.Any school-purposes bus carrying passengers and any regular bus
B.Any regular non-school bus designed to carry more than 24 passengers, plus vehicles in Class D, F, and G
C.Only articulated transit buses, excluding smaller passenger vehicles
D.Only commercial delivery trucks exceeding 11,000 kg gross weight
Explanation: A Class C licence in Ontario permits the holder to operate any regular (non-school) bus designed to carry more than 24 passengers, and also covers the driving privileges of Class D (heavy trucks), Class F (buses up to 24 passengers/ambulances), and Class G (cars/light trucks).
3If you hold a Class C licence in Ontario, under what condition can you operate a school-purposes bus carrying passengers?
A.Under no circumstances, as you must hold a Class B or E licence to drive a school bus carrying passengers
B.Only during school hours or trips sanctioned by a local school board
C.Only if the school bus is carrying 24 passengers or fewer
D.Only if you have held your Class C licence for more than two consecutive years
Explanation: Under Ontario law, a Class C licence does not authorize the holder to operate a school-purposes bus carrying passengers. Operating a school bus carrying passengers requires a Class B licence (for buses carrying more than 24 passengers) or Class E licence (for buses carrying 24 or fewer passengers).
4What is the maximum legal width of any vehicle, including a commercial bus (excluding safety mirrors), allowed on a public highway in Ontario without a special permit?
A.2.4 metres (7 feet 10 inches)
B.2.6 metres (8 feet 6 inches)
C.2.8 metres (9 feet 2 inches)
D.3.0 metres (9 feet 10 inches)
Explanation: According to the Ontario Highway Traffic Act, the maximum legal width for vehicles on public highways is 2.6 metres (8 feet 6 inches). External safety mirrors and warning devices are generally excluded from this measurement.

B.4.00 metres (13 feet 1 inch)
C.4.15 metres (13 feet 7 inches)

Explanation: The maximum legal height for any vehicle operating on Ontario highways is 4.15 metres (13 feet 7 inches). Drivers must always be aware of this limit, especially when passing under low bridges, overpasses, or overhead utility lines.
6How often must a driver perform a daily vehicle inspection (circle check) on a commercial bus in Ontario?
A.At least once every 12 hours of driving
B.At least once within every 24-hour period before driving
C.Every 48 hours, or weekly when the vehicle is parked on weekends
D.Only after completing a trip exceeding 160 kilometres
Explanation: In Ontario, O. Reg. 199/07 mandates that a daily inspection must be completed within 24 hours prior to operating the commercial vehicle on a public highway. The driver must carry a copy of the inspection report and Schedule 1.
7What documents must a driver carry inside the bus during operation to prove the daily inspection was completed?
A.Only the vehicle logbook with hours of service records
B.A copy of the driver's abstract and the vehicle registration
C.The completed daily inspection report for the current 24-hour period and the applicable Schedule 1
D.The carrier's safety rating certificate and a copy of the Highway Traffic Act
Explanation: Ontario Regulation 199/07 requires commercial drivers to carry the completed daily inspection report signed by the driver, along with the correct inspection schedule (such as Schedule 1). These must be produced immediately upon request by an officer.
8What is the purpose of the 'standee line' marked on the floor of an Ontario transit or regular bus?
A.To guide passengers toward the rear exit doors during normal boarding
B.To indicate the safe standing boundary for passengers while the bus is in motion
C.To mark the designated area reserved exclusively for wheelchair users
D.To separate first-class seating from standard seating
Explanation: The standee line (often a contrasting color on the floor) indicates the boundary ahead of which passengers are prohibited from standing while the bus is moving. This ensures the driver's view is not obstructed and that controls remain clear.
9Where is it illegal for passengers to stand when a passenger-carrying bus is in motion on a highway?
A.Anywhere behind the standee line
B.In the aisle between passenger seats
C.Forward of the driver's seat or to the right of the driver, ahead of the standee line
D.On the steps leading to the upper deck of a double-decker bus
Explanation: It is illegal for any passenger to stand in the area to the right of the driver or forward of the standee line while the bus is in motion. This area must be kept clear so the driver's vision and ability to operate the vehicle controls are not compromised.
10What are the minimum visual acuity requirements to qualify for a commercial driver's licence in Ontario?
A.At least 20/20 in each eye individually, with or without corrective lenses
B.At least 20/30 with both eyes open and examined together and 20/100 in the weaker eye, with or without corrective lenses
C.At least 20/40 in both eyes examined together, with no peripheral vision requirement

Ontario Class C Bus Study Tips from Top Performers

1Study the complete Schedule 1 defect list: be prepared to categorize issues like cracked main spring leaves, leaking fuel, or failing headlights as minor or major defects.
2Memorize the hours of service limits: 13 hours driving limit, 14 hours on-duty limit, 10 hours off-duty time (with at least 8 consecutive hours of rest).
3Understand railway crossing rules: buses must stop not less than 5 metres from the nearest rail, open the door to look and listen for trains, and must cross without shifting gears.
4Be familiar with vehicle weight and dimension limits: standard bus width is capped at 2.6 metres, height at 4.15 metres, and length for single vehicles at 12.5 metres.
5Practice following distances: under HTA section 158(2), a commercial vehicle travelling over 60 km/h must not follow within 60 metres of another vehicle, except when overtaking and passing.

Frequently Asked Questions

What vehicles can I drive with an Ontario Class C licence?

A Class C licence permits you to drive any regular (non-school) passenger bus designed to carry more than 24 passengers. It also grants driving privileges for vehicles in Class D (heavy trucks), Class F (buses with up to 24 passengers/ambulances), and Class G (standard passenger cars and light trucks).

Can I operate a school bus with a Class C licence?

No. A Class C licence only permits you to operate regular passenger buses. To drive a school-purposes bus carrying passengers, you must hold a Class B licence (for buses over 24 passengers) or a Class E licence (for buses with 24 or fewer passengers).

How often must Class C drivers submit a medical report in Ontario?

Medical report submission frequency is based on the driver's age: under 46 years of age must submit every 5 years; between 46 and 64 must submit every 3 years; and once the driver is 65 or older, they must submit a medical report every year.

What is the difference between a minor and major defect during daily inspections?

A minor defect (like a minor air leak or minor body damage) must be recorded in the inspection report and reported to the operator, but the vehicle is still legal to drive. A major defect (like a flat tire, pushrod stroke exceeding adjustment limits, or service brake failure) makes the vehicle illegal to operate; it must be taken out of service immediately and cannot be driven until repaired.

Are there logbook exemptions under Ontario hours of service rules?

Yes. A driver is exempt from carrying a daily logbook if they operate within a 160-kilometre radius of their home terminal, start and end their shift at the same terminal daily, have at least 10 hours off-duty between shifts, and the carrier keeps detailed records of the driver's hours.
