Alberta Class 4 · Build recall with a focused review session.
32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Class 4 licence scope
- Covers taxis, ambulances, small buses seating 11 to 24 passengers including the driver, and commercial vehicles up to 24,000 kg registered weight, with a Class 5 prerequisite.
- School bus red lights
- When a school bus displays flashing red lights, traffic in both directions must stop until the lights stop, except on divided highways where only following traffic stops.
- Four-way stop procedure
- The first vehicle to stop proceeds first. If two arrive simultaneously, the vehicle on the right goes first, and left-turning vehicles yield to through traffic.
- Solid yellow line rule
- A solid yellow line on your side of the centre line prohibits passing, and it appears on curves, hillcrests, and other locations with limited sight distance.
- Emergency vehicle response
- When an emergency vehicle approaches with lights and siren, move as far right as practicable and stop, staying clear of intersections until it has passed.
- Playground zone hours
- Playground zones are 30 km/h from 08:30 until one hour after sunset every day, while school zones apply only on school days during posted hours.
- Two-second following rule
- Maintain at least a two-second gap behind the vehicle ahead in good conditions, doubling to four seconds or more on ice, snow, or gravel.
- Stopping distance components
- Total stopping distance equals perception distance plus reaction distance plus braking distance. Reaction distance rises with speed, while braking distance rises with the square of speed.
- Black ice locations
- Black ice forms first on bridges, overpasses, shaded stretches, and intersections, so reduce speed and avoid sudden steering or braking inputs in these areas.
- Rear-wheel skid recovery
- Ease off the accelerator, steer in the direction of the skid, and avoid hard braking until the tires regain traction and the vehicle straightens.
- ABS braking technique
- With anti-lock brakes, apply firm continuous pressure and steer as needed. Do not pump the pedal, since the system modulates pressure automatically.
- Hydroplaning response
- When tires lose contact with a wet road, ease off the throttle and hold the wheel steady without braking until traction returns and steering responds normally.
- Railway crossing clearance
- Stop no closer than 5 m from the nearest rail, check both directions, and never stop on the tracks or proceed until the crossing is fully clear.
- Fatigue break interval
- Take a break of at least 15 minutes every 2 hours, and stop driving when yawning or drifting begins, since caffeine only masks fatigue temporarily.
- Move-over requirement
- When passing stopped emergency, tow, or maintenance vehicles with lights flashing, slow down and move over to leave a safe buffer lane where possible.
- Pre-trip inspection scope
- A daily pre-trip check covers tires, wheel fasteners, brakes, lights, mirrors, wipers, horn, fluids, load securement, and required emergency equipment.
- Commercial tire tread minimum
- Commercial vehicle tires need at least 3 mm of tread in the grooves, with no cuts, bulges, or exposed cord, and dual tires matched in diameter.
- Tiedown aggregate strength
- The combined working load limit of all tiedowns must be at least half the cargo weight, with a minimum of one tiedown per 3 m of length.
- Rear overhang marking
- Cargo extending more than 1.85 m beyond the rear of the vehicle must be marked with a red or orange flag or marker visible to following traffic.
- Air brake leak test
- Build pressure to governor cut-out, stop the engine, and confirm air loss stays within the allowed rate while the low-pressure warning and spring brakes function.
- Slack adjuster pushrod limit
- If brake pushrod travel exceeds the manufacturer's specification during inspection, the vehicle is out of service until the brakes are adjusted or repaired.
- Axle weight distribution
- Loads must be placed so each axle stays within its rated capacity and the total vehicle weight stays within the gross vehicle weight rating.
- Out-of-service fluid leaks
- Coolant, oil, or brake fluid leaks, along with damaged hoses and belts, keep a commercial vehicle out of service until the defect is corrected.
- Documents carried while driving
- Drivers must carry a valid licence of the correct class, vehicle registration, proof of insurance, and any required permits, and produce them to a peace officer.
- Daily driving limit
- Under federal hours of service rules, drivers may not drive after 13 hours of driving, 14 hours on duty, or 16 hours since the last 8 consecutive hours off.
- Daily log retention
- Completed daily logs must be kept for at least 6 months and include duty status changes, total hours, distance driven, and the driver's signed certification.
- Electronic logging devices
- Most federally regulated carriers must use electronic logging devices, with paper logs limited to specific exemptions such as short-haul operations within the allowed radius.
- Daily trip inspection report
- Commercial vehicles require a daily trip inspection report listing defects, and major defects must be reported to the carrier before the vehicle is driven again.
- Maintenance record retention
- Carriers must keep inspection, repair, and maintenance records for the required retention period and make them available to officials on request.
- Over-dimension load permit
- Overweight or over-dimension loads require a permit, and drivers must obey its conditions covering route, travel time, and axle weight limits.
- Safety fitness certificate
- Carriers operating commercial vehicles must hold a valid safety fitness certificate, which authorities may review along with inspection and maintenance records.
- Ambulance driving priority
- An ambulance operating with lights and siren may proceed through intersections only after confirming other traffic has yielded, and must still exercise due care.
