Alberta Class 4 cheat sheet

A Class 4 licence covers taxis, ambulances, small buses (11-24 passengers including the driver), and Class 4 commercial vehicles up to 24,000 kg registered weight; it requires a Class 5 (or higher) prerequisite and a knowledge and road test.

Alberta default urban speed limit is 50 km/h unless posted; playground zones are 30 km/h from 08:30 to one hour after sunset, and school zones are 30 km/h on school days during posted hours.

Passing is prohibited where a solid yellow line is on your side, at uncontrolled intersections, on curves and hillcrests with restricted sight distance, and at railway crossings unless gates and signals permit.

A stopped school bus with flashing red lights requires traffic in both directions to stop until the lights stop flashing; on a divided highway, only traffic approaching from behind the bus must stop.

Right-of-way: a vehicle turning left must yield to oncoming through traffic; a vehicle entering a roadway from a driveway or parking lot yields to all traffic already on the road.

Emergency vehicles with lights and siren: pull as far right as practicable and stop; do not enter an intersection until the emergency vehicle has passed.

Following distance in good conditions is at least 2 seconds; double to 4 seconds or more on ice, snow, gravel, or when following a large vehicle that blocks forward vision.

At a four-way stop, the first vehicle to stop proceeds first; if two stop simultaneously, the vehicle on the right has right-of-way, and a left-turning vehicle yields to a through vehicle.

Total stopping distance = perception distance + reaction distance + braking distance; reaction distance grows linearly with speed, braking distance grows with the square of speed, so doubling speed roughly quadruples braking distance.

Space cushion rule: maintain a following gap of at least one second per 3 m of vehicle length, plus extra margin for heavy or loaded vehicles that need longer braking distances.

Black ice forms first on bridges, overpasses, shaded areas, and intersections; steering and braking inputs on ice should be smooth and single, and ABS requires firm continuous pedal pressure without pumping.

Skid recovery: ease off the accelerator, look and steer where you want to go, and avoid hard braking; for a rear-wheel skid, steer in the direction of the skid.

Fatigue countermeasures: take a 15-minute break at least every 2 hours, stop driving when yawning or lane drifting begins; caffeine and open windows are temporary and do not substitute for sleep.

Hydroplaning onset depends on speed, tire tread depth, and water depth; ease off the throttle and avoid braking until tires regain contact with the road.

Railway crossing protocol: stop no closer than 5 m from the nearest rail, look both ways, and do not proceed until the track is clear in both directions; never stop on the tracks.

Work zone and incident scenes: reduce speed, obey flag persons, and move over or slow down when passing stopped emergency or tow vehicles with lights flashing.

Daily pre-trip inspection covers tires and tread, wheel fasteners, brakes and air pressure build-up, lights, mirrors, wipers, horn, fluid levels, load securement, and emergency equipment.

Minimum tire tread for commercial vehicles is 3 mm in the tread grooves; inspect for cuts, bulges, exposed cord, and matched dual tire diameters to prevent sidewall contact and uneven wear.

Air brake check sequence: build system pressure to governor cut-out, stop the engine, verify leak rate limits, test the low-pressure warning, and confirm spring brakes apply when pressure drops.

Load securement requires the aggregate working load limit of tiedowns to be at least 50% of the cargo weight, with a minimum of one tiedown per 3 m of cargo length and at least two tiedowns.

Cargo must not extend more than 1.5 m beyond the front of the vehicle or more than 1.85 m beyond the rear, and rear overhang must be flagged with a red or orange marker.

Loads must be distributed to respect axle weight ratings and the vehicle's gross weight rating; check weight scale tickets when in doubt rather than estimating.

Brake adjustment and slack adjuster checks are part of the pre-trip; pushrod travel beyond the manufacturer's limit means the vehicle is out of service until repaired.

Coolant, oil, and brake fluid leaks, plus damaged hoses and belts, are grounds to keep the vehicle out of service until corrected.

Drivers of commercial vehicles must carry a valid licence of the correct class, vehicle registration, proof of insurance, and any required permits; produce them on demand to a peace officer.

Hours of service in Alberta follow the federal Commercial Vehicle Drivers Hours of Service Regulations: no driving after 13 hours of driving in a day, 14 hours on duty, or 16 hours elapsed since the last 8 consecutive hours off duty.

Daily logs must be completed for each 24-hour period, retained for at least 6 months, and include duty status changes, total hours, distance, and the driver's signature and certification.

Electronic logging devices are mandatory for most federally regulated carriers; paper logs are permitted only under specific exemptions such as short-haul operations within the allowed radius.

A daily trip inspection report is required for commercial vehicles, with defects recorded and major defects reported to the carrier before the vehicle is driven again.

Carriers must maintain records of inspections, repairs, and maintenance for the required retention period and make them available for inspection by officials.

Cargo and passenger-carrying vehicles must meet annual or periodic inspection requirements, and safety fitness certificates are required for carriers operating commercial vehicles.

Overweight or over-dimension loads require a permit, and drivers must obey permit conditions including route, time, and axle weight restrictions.

Daily pre-trip inspection covers tires and tread, wheel fasteners, brakes and air pressure build-up, lights, mirrors, wipers, horn, fluid levels, load securement, and emergency equipment.

Minimum tire tread for commercial vehicles is 3 mm in the tread grooves; inspect for cuts, bulges, exposed cord, and matched dual tire diameters to prevent sidewall contact and uneven wear.

Air brake check sequence: build system pressure to governor cut-out, stop the engine, verify leak rate limits, test the low-pressure warning, and confirm spring brakes apply when pressure drops.

Load securement requires the aggregate working load limit of tiedowns to be at least 50% of the cargo weight, with a minimum of one tiedown per 3 m of cargo length and at least two tiedowns.

Cargo must not extend more than 1.5 m beyond the front of the vehicle or more than 1.85 m beyond the rear, and rear overhang must be flagged with a red or orange marker.

Loads must be distributed to respect axle weight ratings and the vehicle's gross weight rating; check weight scale tickets when in doubt rather than estimating.

Brake adjustment and slack adjuster checks are part of the pre-trip; pushrod travel beyond the manufacturer's limit means the vehicle is out of service until repaired.

Coolant, oil, and brake fluid leaks, plus damaged hoses and belts, are grounds to keep the vehicle out of service until corrected.

Drivers of commercial vehicles must carry a valid licence of the correct class, vehicle registration, proof of insurance, and any required permits; produce them on demand to a peace officer.

Hours of service in Alberta follow the federal Commercial Vehicle Drivers Hours of Service Regulations: no driving after 13 hours of driving in a day, 14 hours on duty, or 16 hours elapsed since the last 8 consecutive hours off duty.

Daily logs must be completed for each 24-hour period, retained for at least 6 months, and include duty status changes, total hours, distance, and the driver's signature and certification.

Electronic logging devices are mandatory for most federally regulated carriers; paper logs are permitted only under specific exemptions such as short-haul operations within the allowed radius.

A daily trip inspection report is required for commercial vehicles, with defects recorded and major defects reported to the carrier before the vehicle is driven again.

Carriers must maintain records of inspections, repairs, and maintenance for the required retention period and make them available for inspection by officials.

Cargo and passenger-carrying vehicles must meet annual or periodic inspection requirements, and safety fitness certificates are required for carriers operating commercial vehicles.

Overweight or over-dimension loads require a permit, and drivers must obey permit conditions including route, time, and axle weight restrictions.

A Class 4 licence covers taxis, ambulances, small buses (11-24 passengers including the driver), and Class 4 commercial vehicles up to 24,000 kg registered weight; it requires a Class 5 (or higher) prerequisite and a knowledge and road test.

Alberta default urban speed limit is 50 km/h unless posted; playground zones are 30 km/h from 08:30 to one hour after sunset, and school zones are 30 km/h on school days during posted hours.

Passing is prohibited where a solid yellow line is on your side, at uncontrolled intersections, on curves and hillcrests with restricted sight distance, and at railway crossings unless gates and signals permit.

A stopped school bus with flashing red lights requires traffic in both directions to stop until the lights stop flashing; on a divided highway, only traffic approaching from behind the bus must stop.

Right-of-way: a vehicle turning left must yield to oncoming through traffic; a vehicle entering a roadway from a driveway or parking lot yields to all traffic already on the road.

Emergency vehicles with lights and siren: pull as far right as practicable and stop; do not enter an intersection until the emergency vehicle has passed.

Following distance in good conditions is at least 2 seconds; double to 4 seconds or more on ice, snow, gravel, or when following a large vehicle that blocks forward vision.

At a four-way stop, the first vehicle to stop proceeds first; if two stop simultaneously, the vehicle on the right has right-of-way, and a left-turning vehicle yields to a through vehicle.

Total stopping distance = perception distance + reaction distance + braking distance; reaction distance grows linearly with speed, braking distance grows with the square of speed, so doubling speed roughly quadruples braking distance.

Space cushion rule: maintain a following gap of at least one second per 3 m of vehicle length, plus extra margin for heavy or loaded vehicles that need longer braking distances.

Black ice forms first on bridges, overpasses, shaded areas, and intersections; steering and braking inputs on ice should be smooth and single, and ABS requires firm continuous pedal pressure without pumping.

Skid recovery: ease off the accelerator, look and steer where you want to go, and avoid hard braking; for a rear-wheel skid, steer in the direction of the skid.

Fatigue countermeasures: take a 15-minute break at least every 2 hours, stop driving when yawning or lane drifting begins; caffeine and open windows are temporary and do not substitute for sleep.

Hydroplaning onset depends on speed, tire tread depth, and water depth; ease off the throttle and avoid braking until tires regain contact with the road.
