Quebec Class 1 cheat sheet
Quebec Class 1 · Keep the key ideas within reach.
Road signs, signals and road markings
Quebec sign shapes carry meaning: octagon = stop, inverted triangle (yield) = cédez le passage, diamond = warning, rectangle = regulatory or information, pennant = school zone or school bus related warnings.
Colour code: red = prohibition/stop/yield, yellow = warning, orange = construction/work zone, green = direction/guidance, blue = services/information, brown = points of interest, white with black = regulatory.
A flashing red signal is treated as a stop sign: full stop, yield to cross traffic and pedestrians, proceed when safe. A flashing yellow means slow down and proceed with caution.
A steady green arrow gives protected right-of-way in the arrow direction; a green light with no arrow means you must still yield to oncoming traffic when turning left.
Yellow centre line = two-way traffic (passing permitted if broken on your side); double solid yellow = no passing both directions; white line = traffic moving in the same direction.
A solid white line at the right edge marks the shoulder boundary; crossing it is permitted only when safe. Yellow lines on the left edge indicate the left boundary of a divided highway.
Stop line: solid white bar across your lane - stop before it. If a crosswalk is marked, stop before the crosswalk, never on it.
Railway crossing: round warning sign with X and two red lights means stop when lights flash and never pass while the gate is descending or down; a crossbuck marks the crossing point.
Rules of the road and right-of-way
Right-of-way is yielded, never taken: at an uncontrolled intersection the vehicle on the right has priority; a vehicle already in the intersection has priority over entering traffic.
Left-turning vehicle yields to oncoming through traffic and to pedestrians in the crosswalk it is entering; right turn on red is permitted after a full stop and yield, unless a sign prohibits it.
Pedestrians in a marked or unmarked crosswalk have priority; a driver must stop and remain stopped until they have cleared the driver's lane and the adjacent lane.
School buses with flashing red lights and extended stop arm: traffic in both directions must stop (on a divided highway, only traffic approaching from behind the bus must stop).
Emergency vehicles with sirens/lights: pull to the right and stop; if in an intersection, clear it first. Never follow closer than 150 m behind an emergency vehicle responding to a call.
Speed limits: 50 km/h in built-up areas unless posted, 90 km/h on highways unless posted, 100 km/h on autoroutes unless posted; limits are maximums for ideal conditions only.
Passing on the right is allowed only in specific cases (another vehicle turning left, multi-lane same-direction road); otherwise pass on the left and never cross a solid line to pass.
Following distance for heavy vehicles: at least 3 seconds in ideal conditions, 4 or more seconds at night, in rain, or when loaded; more when following a snowplow or on gravel.
Heavy vehicle pre-trip inspection and vehicle condition
Pre-trip inspection is a legal duty before each trip: check tires, wheels, brakes, lights, steering, suspension, coupling devices, cargo securement, fluids and emergency equipment.
Tire rules: minimum tread depth 1.6 mm on steering axle and 1.6 mm elsewhere for the tread pattern; no cuts, bulges, exposed cords, or sidewall damage; dual tires must not touch.
Brake adjustment: with air brakes, pushrod stroke must be within the manufacturer's limit (commonly 51 mm / 2 in for clamp-type chambers, less for long-stroke); an over-stroke means the brake is out of adjustment.
Lighting: all required lamps must work - headlights high/low, taillights, brake lights, turn signals, four-way flashers, clearance/marker lamps, licence plate lamp, and reflectors.
Coupling check: fifth-wheel jaws fully closed around the kingpin, no gap between plate and trailer, locking lever secured, air lines and electrical cord connected without chafing, landing gear fully raised.
Leaks: any continuous air leak, oil, coolant, fuel, or hydraulic leak that drips is a defect that must be corrected before the vehicle is operated.
Emergency equipment: fire extinguisher (charged, secured, accessible), warning triangles (at least three), spare fuses, and a first-aid kit where required.
Defects found in inspection must be recorded and reported; a driver may not operate a vehicle with a defect that affects safe operation, and a major defect requires the vehicle to be taken out of service.
Air brake system operation and inspection
Normal operating pressure: build to governor cut-out around 830-930 kPa (120-135 psi); low-pressure warning must activate before pressure falls below about 420 kPa (60 psi).
Static leak test: with engine off, fully charged and brakes released, pressure loss must not exceed about 20 kPa (3 psi) per minute; with brakes applied, not more than about 28 kPa (4 psi) per minute.
Applied leak test: hold full brake application for one minute with engine off - a loss greater than about 28 kPa (4 psi) indicates a leak requiring repair.
Low-pressure test: pump down with the engine off; warning buzzer/light must come on before 420 kPa, and the spring (parking) brakes must apply automatically at about 140-280 kPa (20-40 psi).
Compressor build rate: from about 590 to 830 kPa (85-120 psi) at governed engine speed, pressure should build at no less than roughly 85 kPa (12 psi) per minute.
Slack adjuster / pushrod check: apply brakes fully and measure pushrod travel; excessive stroke means the brake is out of adjustment and the vehicle must not be driven.
Never fan the brakes on a downgrade: continuous light application overheats drums and causes brake fade. Use a lower gear, apply firm braking to a lower speed, then release and let brakes cool.
Drain air tanks daily (supply and service tanks) to remove moisture and oil; a failed drain, frozen line, or alcohol evaporator failure can cause brake failure in cold weather.
Cargo securement, weights and dimensions
Securement standard: cargo must be secured so it cannot leak, spill, blow off, shift, or fall; the aggregate working load limit (WLL) of tiedowns must be at least 50% of the cargo weight.
Number of tiedowns: for cargo over 1.52 m (5 ft) long and 1.52 m or less, at least two; for cargo longer than 3.04 m (10 ft), at least one additional tiedown per 3.04 m of length.
Each tiedown must be attached to the vehicle and to the cargo, and must be within 1.22 m (4 ft) of the end of the cargo; tiedowns must not be loose, knotted, or worn beyond limits.
Height limit in Quebec: 4.15 m (13 ft 7 in) generally; width 2.6 m (8 ft 6 in); length 12.5 m for a single vehicle and 23 m for a tractor-trailer combination on designated routes (verify current limits).
Axle and gross weight limits: steering axle typically 5,500 kg; tandem axle group 17,000 kg; tridem 24,000 kg; gross vehicle weight 46,500 kg on Quebec roads (some routes differ - check signs and permits).
Overweight or oversize movements require a permit; escort and flagging requirements, travel times and route restrictions are specified on the permit.
Inspection after driving: stop and re-check tiedowns, tarps and load distribution after the first 80 km and every 3 hours or 240 km thereafter.
Weight distribution: load heavy items low and centred over the axles; an unbalanced load reduces steering traction and can overload an axle even when gross weight is legal.
Hours of service and driver fatigue management
Daily driving limit: no more than 13 hours of driving in a day; a driver must have at least 10 hours off duty (of which 8 are consecutive) in each day.
Cycle limits: 70 hours on duty in 7 days, or 120 hours on duty in 14 days, depending on the cycle the carrier uses; a reset requires 36 consecutive hours off duty (or 24 hours in some cycles).
Mandatory rest break: no driving after 13 hours of on-duty time without at least 8 consecutive hours off duty; a 30-minute break is required after 8 hours of driving.
Daily log: record duty status (off duty, sleeper, driving, on-duty not driving) in 15-minute increments, total hours, and the previous 14 days of logs must be carried and produced on request.
Electronic logging devices (ELD) are mandatory for most commercial vehicles; paper logs are permitted only in limited circumstances such as an ELD malfunction.
Fatigue signs: yawning, heavy eyelids, drifting, missing signs or exits, difficulty remembering the last kilometres - these require stopping for rest, not caffeine alone.
Sleep hygiene on the road: aim for 7-9 hours of sleep per 24 hours, keep the sleeper berth dark and cool, and avoid alcohol and sedating medication before driving.
A driver who feels drowsy must stop in a safe place and rest; the only effective countermeasure for fatigue is sleep, not fresh air, music, or energy drinks.
Safe driving practices for heavy vehicles (speed, space, braking, grades)
Stopping distance grows with the square of speed: a loaded tractor-trailer needs roughly 2-4 times the stopping distance of a car, more on wet or icy pavement.
Space cushion: maintain at least 3 seconds behind the vehicle ahead, 4 or more at night or in bad weather; add one second per 3 m of vehicle length above a car's length.
Downhill technique: select a gear that holds a safe speed without braking (engine braking), use the same gear you would use to climb the grade; brake firmly to reduce speed, then release.
Uphill technique: downshift before the grade, not on it; keep engine rpm in the power band and watch coolant and transmission temperature.
Speed on curves: reduce speed before entering, not in the curve; a high centre of gravity (loaded trailer, tanker) increases rollover risk - posted curve speeds are for cars, not trucks.
Braking: brake in a straight line where possible, avoid hard braking on curves, and be aware of brake fade on long descents; use engine retarders where permitted.
Blind spots: large vehicles have blind spots on both sides, directly behind, and in front; signal early, check mirrors, and never linger alongside a truck's right side.
Weather: reduce speed in rain, snow, fog and wind; hydroplaning risk rises above 80 km/h on wet pavement; use low-beam headlights in fog and never stop in a live lane.
Hazard perception and emergency procedures
Scan 12-15 seconds ahead and check mirrors every 5-8 seconds; identify escape routes before they are needed, and cover the brake when a hazard is developing.
Brake failure: pump the brakes, downshift progressively, use the engine brake and parking brake gradually, look for an escape ramp or uphill grade; do not shut off the engine.
Tire blowout: hold the wheel firmly, keep the accelerator steady or ease off, avoid hard braking, and steer straight until the vehicle stabilizes before pulling over.
Trailer jackknife or skid: release the brakes to regain rolling traction, steer in the direction of the skid (where you want the front to go), and avoid overcorrecting.
Fire: stop, shut off the engine, evacuate occupants upwind, call emergency services; do not open the hood fully on an engine fire, and never fight a fire that threatens the cargo or fuel tank.
Railway crossing emergency: if the vehicle stalls on the tracks, get everyone out and away, then call the railway emergency number posted at the crossing; move away at an angle from the track.
Hydroplaning: ease off the accelerator, avoid braking or steering sharply, and hold the wheel straight until tires regain contact; reduce speed in heavy rain.
Collision or incident: secure the scene, set out warning triangles, call 911, exchange information, and do not move an injured person unless there is immediate danger.
Dangerous goods and transportation of hazardous materials
Dangerous goods are classified in 9 classes: 1 explosives, 2 gases, 3 flammable liquids, 4 flammable solids, 5 oxidizers/organic peroxides, 6 toxic/infectious, 7 radioactive, 8 corrosive, 9 miscellaneous.
Shipping documents: the dangerous goods document must accompany the shipment and include the UN number, proper shipping name, class, packing group, quantity, and emergency contact number.
Placards: required on the vehicle for most dangerous goods shipments; the placard must match the class of the goods and must be visible from both sides and the rear.
Training: anyone handling or transporting dangerous goods must be trained and hold a certificate, renewed every 3 years, covering classification, marking, labelling, placarding, and emergency response.
Segregation and loading: incompatible classes must not be loaded together; keep dangerous goods away from heat, food, and animals, and secure cylinders upright.
Emergency response: use the ERAP (emergency response assistance plan) and the emergency number on the document; approach from upwind, keep people back, and do not touch spilled material.
Reporting: a release of dangerous goods must be reported immediately to the carrier, the emergency number, and the appropriate authority (Environment Canada / provincial environment ministry).
Prohibited acts: smoking, open flames, and use of devices that could ignite vapours are prohibited near vehicles carrying flammable liquids or gases.
