Quebec Class 1 flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Octagon sign meaning

An eight-sided red sign always means stop. Come to a complete stop before the stop line or crosswalk, yield to cross traffic and pedestrians, then proceed only when the way is clear.

Flashing red signal

A flashing red light is treated exactly like a stop sign: full stop, yield to cross traffic and pedestrians, and proceed when safe. A flashing yellow means slow down and proceed with caution.

Yellow centre lines

A broken yellow line on your side permits passing; a solid yellow line on your side prohibits passing. Double solid yellow lines prohibit passing in both directions.

School bus red lights

When a school bus displays flashing red lights and its stop arm, traffic in both directions must stop. On a divided highway, only traffic approaching from behind the bus must stop.

Uncontrolled intersection priority

At an intersection with no signs or signals, the vehicle on the right has the right-of-way. A vehicle already in the intersection has priority over entering traffic.

Right turn on red

A right turn on a red light is permitted after a complete stop and yield to pedestrians and cross traffic, unless a sign prohibits the turn. Left turns on red are generally prohibited.

Minimum tire tread depth

Quebec requires at least 1.6 mm of tread depth on all tires of a heavy vehicle. Tires with cuts, bulges, exposed cords or sidewall damage must be replaced before operation.

Fifth-wheel coupling check

Verify the jaws are fully closed around the kingpin, no gap exists between the fifth-wheel plate and the trailer, the locking lever is secured, and the landing gear is fully raised.

Brake pushrod stroke limit

With brakes fully applied, pushrod travel must be within the manufacturer's limit, commonly 51 mm (2 in) for clamp-type chambers. An over-stroke means the brake is out of adjustment and the vehicle must not be driven.

Air brake static leak test

With the engine off, system fully charged and brakes released, pressure loss must not exceed about 20 kPa (3 psi) per minute. With brakes applied, loss must not exceed about 28 kPa (4 psi) per minute.

Low air pressure warning

The low-pressure warning buzzer and light must activate before pressure falls below about 420 kPa (60 psi). Spring parking brakes apply automatically at roughly 140-280 kPa (20-40 psi).

Compressor build rate

At governed engine speed, pressure should build from about 590 to 830 kPa (85-120 psi) at no less than roughly 85 kPa (12 psi) per minute. A slower build indicates a compressor or leak problem.

Brake fade prevention

Never fan the brakes on a downgrade. Select a low gear, brake firmly to reduce speed, then release and let the drums cool. Continuous light application overheats brakes and causes fade.

Tiedown working load limit

The combined working load limit of all tiedowns must be at least 50% of the cargo weight. Each tiedown must be within 1.22 m (4 ft) of the end of the cargo.

Number of tiedowns required

Cargo longer than 1.52 m (5 ft) and 1.52 m or less in length requires at least two tiedowns. Cargo longer than 3.04 m (10 ft) requires one additional tiedown per 3.04 m.

Quebec height and width limits

The general maximum height is 4.15 m (13 ft 7 in) and maximum width is 2.6 m (8 ft 6 in). Oversize loads require a permit specifying route, escort and travel-time conditions.

Load re-check interval

Stop and re-check tiedowns, tarps and load distribution after the first 80 km, then every 3 hours or 240 km thereafter. Shifting cargo must be corrected before continuing.

Daily driving limit

A driver may not drive more than 13 hours in a day and must have at least 10 hours off duty, of which 8 hours must be consecutive, in each day.

Cycle hour limits

Drivers work within a 70-hour/7-day or 120-hour/14-day cycle. A reset requires 36 consecutive hours off duty, or 24 hours in certain cycles.

Mandatory rest break

A driver may not drive after 8 hours of driving without taking at least a 30-minute break. No driving is permitted after 13 hours of on-duty time without 8 consecutive hours off.

Electronic logging device requirement

Most commercial vehicles must be equipped with an electronic logging device that records duty status automatically. Paper logs are allowed only in limited cases such as an ELD malfunction.

Heavy vehicle following distance

Maintain at least 3 seconds behind the vehicle ahead in ideal conditions, and 4 or more seconds at night, in rain, or when fully loaded. Add time for longer or heavier combinations.

Downgrade gear selection

Select the same gear you would use to climb the grade, before starting down. Engine braking holds speed without heating the brakes, which prevents brake fade on long descents.

Stopping distance versus speed

Stopping distance increases with the square of speed. A loaded tractor-trailer needs roughly 2 to 4 times the stopping distance of a car, and more on wet or icy pavement.

Brake failure response

Pump the brakes, downshift progressively, use the engine brake and apply the parking brake gradually, and look for an escape ramp. Do not shut off the engine during the emergency.

Tire blowout response

Hold the steering wheel firmly, keep the accelerator steady or ease off, avoid hard braking, and steer straight until the vehicle stabilizes before pulling off the road.

Vehicle fire response

Stop, shut off the engine, evacuate occupants upwind, and call emergency services. Do not fully open the hood on an engine fire and never fight a fire threatening the fuel tank.

Stalled on railway crossing

Get everyone out and away from the vehicle at an angle to the track, then call the railway emergency number posted at the crossing. Never stay inside a vehicle stalled on the tracks.

Nine dangerous goods classes

Class 1 explosives, 2 gases, 3 flammable liquids, 4 flammable solids, 5 oxidizers and organic peroxides, 6 toxic and infectious, 7 radioactive, 8 corrosive, 9 miscellaneous.

Dangerous goods shipping document

The document must accompany the shipment and state the UN number, proper shipping name, class, packing group, quantity, and a 24-hour emergency contact number.

Dangerous goods training certificate

Anyone handling or transporting dangerous goods must be trained and hold a certificate covering classification, marking, labelling, placarding and emergency response. It must be renewed every 3 years.

Dangerous goods release reporting

Any release of dangerous goods must be reported immediately to the carrier, the emergency number on the shipping document, and the appropriate environmental authority. Approach from upwind and keep people back.
