- Class C licence scope
- In Ontario, a Class C licence permits driving a bus with a designed seating capacity of 24 or more passengers, including any trailer towed behind the bus.
- School bus red lights
- When a school bus has its red lights flashing, traffic in both directions must stop, unless the road is divided by a median, in which case only traffic approaching from behind must stop.
- Demerit points for careless driving
- Careless driving carries 6 demerit points in Ontario, the same as racing, while failing to remain at a collision carries 7 points.
- Zero blood alcohol rule
- Drivers under 22 and novice drivers must have zero blood alcohol; fully licensed drivers are over the legal limit at 0.08 g per 100 mL of blood.
- Off-tracking on a turn
- The rear wheels of a long bus cut inside the path of the front wheels, so the driver must swing wide before the corner and check the right mirror for clearance.
- Railway crossing rule
- At a railway crossing, stop at least 5 metres from the nearest rail when a signal or gate is active, and never shift gears while crossing the tracks.
- Following distance rule
- Use at least a 2-second following gap in ideal conditions, and add 1 second for each adverse factor such as rain, darkness, heavy load or gravel surface.
- Daily trip inspection requirement
- A bus must receive a daily trip inspection before its first trip each day, and the signed report must be completed whether or not any defect is found.
- Major defect handling
- A major defect such as brake failure, a broken spring or a loose wheel means the bus must be taken out of service until repaired, and the defect must be recorded.
- Inspection report retention
- The operator must keep each daily inspection report for at least 6 months, and it must be available for inspection by a Ministry officer on request.
- Air pressure build-up test
- At fast idle, air pressure must build from 85 psi to 100 psi within 45 seconds; a slower build indicates a faulty compressor or governor.
- Static air leak test
- With the engine off and the brakes applied, pressure loss must not exceed 3 psi in one minute for a single vehicle, or 4 psi for a combination.
- Low-pressure warning threshold
- The low-pressure warning buzzer and light must activate before pressure drops below 60 psi, and the spring brakes must apply automatically between 20 and 45 psi.
- Governor cut-out pressure
- The compressor governor normally cuts out between 120 and 135 psi and cuts in at about 100 psi, and the system must not exceed the manufacturer's maximum.
- Slack adjuster push rod limit
- With the brakes applied, push rod travel must not exceed the limit stamped on the brake chamber, typically 2 inches for a type 30 chamber.
- Cargo tiedown strength rule
- The aggregate working load limit of all tiedowns must be at least 50% of the weight of the cargo being secured.
- Tiedown spacing rule
- A tiedown is required for every 3 metres of cargo length, and at least 2 tiedowns are required for any load longer than 1.5 metres but no more than 3 metres.
- Ontario gross weight limit
- The legal gross vehicle weight limit in Ontario is 63,500 kg on designated highways, with single-axle limits typically 9,000 kg and tandem limits 18,000 kg.
- 13-hour driving limit
- A driver may not drive after 13 hours of on-duty time in a day, and must take 8 consecutive hours off duty before the next day.
- 14-hour on-duty limit
- A driver must not drive after 14 hours of on-duty time in a day, and must have at least 10 hours off duty in the preceding 24 hours.
- Cycle hour limits
- A driver must not accumulate more than 70 hours of on-duty time in 7 consecutive days, or 120 hours in 14 days.
- 30-minute break rule
- A driver must take a 30-minute break after 8 hours of driving or on-duty time before continuing to drive.
- Daily log retention
- A daily log must be completed for each 24-hour period showing on-duty, off-duty, driving and sleeper berth time, and must be kept for 6 months.
- Overweight permit contents
- An overweight permit must specify the route, axle weights and expiry date, and must be carried in the vehicle and produced on demand.
- CVOR certificate
- A commercial vehicle operator's registration certificate must be carried in the vehicle and produced on request by a Ministry officer.
- Hands-free device rule
- No hand-held device may be used while driving; only hands-free functions and 911 calls are permitted, and display screens must be configured before driving.
- Right turn on red
- A right turn on a red light is permitted after a full stop unless a sign prohibits it; a left turn on red is permitted only from a one-way to a one-way street.
- Hydroplaning risk speed
- Hydroplaning risk increases above 80 km/h on wet pavement, so the driver should reduce speed and avoid sudden braking or steering inputs.
- Tire blowout response
- When a tire blows out, hold the steering wheel firmly, ease off the accelerator and avoid hard braking until the vehicle slows.
- Bus tire tread minimum
- The minimum tread depth is 1.5 mm for front tires and 1.5 mm for other tires on a bus; check also for cuts, bulges and exposed cords.
- Emergency equipment on board
- A bus must carry a charged and mounted fire extinguisher, a first aid kit and warning triangles, and the driver must check them before each trip.
- Spring brake operation
- The parking spring brake is applied by spring pressure and released by air pressure, so a loss of air pressure applies the brakes automatically.
