- Class 1 licence scope
- Authorizes driving a tractor-trailer or truck-trailer combination where the towed unit exceeds 4,600 kg, plus vehicles in lower classes.
- MELT hours requirement
- Alberta's Mandatory Entry-Level Training requires at least 113 hours of instruction before a Class 1 road test.
- Class 1 minimum age
- An applicant must be at least 18 years old to obtain a Class 1 learner's permit in Alberta.
- Air brake endorsement Q
- A separate endorsement earned by passing a written air brake test and a practical air brake inspection.
- Demerit suspension threshold
- A fully licensed driver is suspended at 15 demerit points; commercial drivers face stricter carrier safety monitoring.
- Pre-trip inspection validity
- A pre-trip inspection must be completed within 24 hours before driving and applies only to that vehicle configuration.
- Fifth wheel coupling test
- Apply the trailer brakes and pull the tractor forward gently; the kingpin must stay locked to confirm proper coupling.
- Steer tire tread minimum
- Steer tires require at least 4 mm of tread depth; drive and trailer tires need at least 2 mm in major grooves.
- Low-air warning threshold
- The low-pressure warning buzzer or light must activate before system pressure drops below 60 psi.
- Spring brake application range
- Spring (parking) brakes apply automatically when system pressure falls to approximately 20 to 45 psi.
- Trip inspection retention
- The carrier must keep each signed trip inspection report for at least 31 days after it is completed.
- Normal air pressure range
- Air brake systems normally operate between 100 and 120 psi, with the compressor cutting out near 120 psi.
- Leak-down test limits
- With brakes released and engine off, pressure loss must not exceed 3 psi per minute single or 4 psi combination.
- Applied leak test limits
- With the brake pedal held fully for one minute, loss must not exceed 4 psi single or 6 psi combination.
- Brake fade control
- Overheated brakes lose effectiveness; control speed by gearing down before a descent rather than riding the brakes.
- Total stopping distance
- Total stopping distance equals perception distance plus reaction distance plus braking distance, all increasing with speed.
- Aggregate WLL rule
- The combined working load limit of all tiedowns must equal at least 50 percent of the weight of the cargo.
- Minimum tiedown count
- Cargo longer than 1.52 m or heavier than 500 kg requires at least two tiedowns; smaller loads require one.
- Front-end structure strength
- A front-end structure must withstand a force equal to 0.4 times the cargo weight; rear structures 0.25 times.
- Tiedown re-inspection interval
- Inspect cargo and tiedowns after the first 80 km, then every 3 hours or 240 km during the trip.
- Steering axle weight limit
- The maximum legal weight on a steering axle in Alberta is 5,500 kg; tandem groups are limited to 17,000 kg.
- Maximum legal width
- The maximum legal vehicle width is 2.6 m; maximum height is 4.15 m without an over-dimensional permit.
- Tridem axle group limit
- A tridem axle group is limited to 24,000 kg, subject to tire count and axle spacing requirements.
- Overweight permit rule
- A permit is required when axle or gross weights exceed legal limits; registered gross weight must cover actual loaded weight.
- Daily driving limit
- A driver may drive at most 13 hours in a 24-hour period and must be on duty no more than 14 hours.
- Cycle limits
- Drivers may accumulate 70 hours on duty in 7 days or 120 hours in 14 days, followed by a required reset.
- Log retention period
- Daily logs must be completed for each 24-hour period and retained by the carrier for at least 6 months.
- Sleeper berth split
- The 10-hour off-duty requirement may be split into two periods, one of at least 8 hours and one of at least 2 hours.
- Trip inspection frequency
- A commercial vehicle must receive a trip inspection every 24 hours, and a report must be filed even with no defects.
- Major defect action
- A major defect requires the vehicle to be taken out of service until the defect is repaired and re-inspected.
- Safety Fitness rating
- Carriers receive a Safety Fitness rating based on inspections, collisions, and audits, which can trigger corrective action.
- Falsifying logs offence
- Knowingly recording false duty status information is an offence under provincial and federal law and can void a licence.
