Class 5 Theory Test cheat sheet

A Class 5 licence is the full (non-learner) car licence class in most Canadian provinces; heavy vehicles require a Class 1, 2, 3, or 4 depending on the vehicle, so Class 5 alone does not authorise heavy vehicle operation.

Minimum age for a full Class 5 licence is typically 18 (after a graduated licensing program); a learner stage generally starts at 16 with a supervising driver who holds a full licence.

Graduated licensing stages (Learner, Novice/Intermediate, Full) impose conditions: zero blood alcohol for novice drivers, passenger limits for novice drivers in some provinces, and no driving between midnight and 5 a.m. for learners in some jurisdictions.

Eligibility for a heavy vehicle class generally requires holding a full Class 5 (or equivalent) for a set period (commonly 1-3 years depending on class and province) and being at least 18-21 years old.

Medical fitness: heavy vehicle applicants must pass a medical examination; drivers with certain conditions (uncontrolled seizures, insulin-dependent diabetes with hypoglycemia history, vision below the standard) may be restricted or refused.

Vision standard for heavy vehicles is stricter than for cars: corrected visual acuity typically 20/30 or better in the better eye and a specified horizontal visual field (often 150 degrees or more).

Knowledge and road tests: a written knowledge test on rules of the road and heavy vehicle specifics, plus a practical road test in the class of vehicle applied for, are required before a heavy vehicle licence is issued.

Criminal Code and driving record checks apply: serious offences (impaired driving, dangerous driving) can disqualify an applicant or delay eligibility; demerit-point thresholds can suspend a licence.

Air brake endorsement (often called a Q or Z endorsement depending on province) is required to drive a vehicle equipped with air brakes and requires a separate written and practical test.

Class 1: semi-trailer trucks and tractor-trailers; typically permits towing a trailer with a gross vehicle weight exceeding 4,600 kg, or any combination where the towed unit exceeds 4,600 kg.

Class 2: buses and other passenger vehicles designed to carry more than 24 passengers, including school buses in many provinces.

Class 3: single-unit trucks (straight trucks) with a registered gross vehicle weight over 11,000 kg, and trucks towing a trailer up to 4,600 kg.

Class 4: taxis, limousines, small buses (up to 24 passengers), and ambulances; some provinces split this into 4A/4B/4C subtypes.

Class 5: cars, light trucks, and vans up to 4,600 kg gross vehicle weight, plus a towed trailer up to 4,600 kg; this is the ordinary full car licence.

Class 6: motorcycles and mopeds; a separate knowledge and road test is required, and the graduated licensing stages apply.

Class 7: learner stage for cars (Class 7L) and motorcycles (Class 7M); must be accompanied and follow novice restrictions.

Air brake endorsement (Q/Z): required on any vehicle with air brakes; without it, driving such a vehicle is an offence even if the base class is correct.

Endorsements: school bus (S), ambulance, and dangerous goods endorsements may be required in addition to the base class; endorsements are province-specific.

Following distance: heavy vehicles need more stopping distance than cars due to mass; use a 4-second following distance in good conditions, more in rain, snow, or when loaded.

Braking: air-brake systems have a lag (typically 0.3-0.5 seconds) before brakes engage; total stopping distance is significantly longer than a car's, especially when loaded.

Blind spots (no-zones): heavy vehicles have large blind spots directly in front, on both sides, and behind; truck drivers may not see a car within several metres of the cab or trailer.

Right turns: large vehicles often swing left before turning right (off-tracking); cyclists and pedestrians should not pass on the right side of a turning truck.

Off-tracking: the rear wheels of a long vehicle track inside the front wheels' path on turns; drivers must allow extra room and check mirrors for the trailer.

Speed management: downgrades require selecting a lower gear before descending (engine braking); use of engine brakes may be restricted in urban areas, but service brakes should not be relied on alone on long descents.

Load security: cargo must be secured so it cannot shift or fall; an unsecured or overloaded load changes handling and braking and is a safety and legal violation.

Sharing the road: pass a heavy vehicle only when you can see the driver's mirrors; do not linger alongside; allow extra time when a truck is turning or merging.

Fatigue and hours of service: commercial drivers are subject to hours-of-service limits; fatigue impairs reaction time and is a leading cause of heavy vehicle collisions.

Brake systems: heavy vehicles must have service brakes on all wheels, a parking brake, and (where equipped) an emergency/secondary brake; air-brake systems must meet pressure and leak-down standards.

Lighting: headlamps, tail lamps, brake lamps, turn signals, clearance lamps, and reflectors must be present, working, and correctly aimed; daytime running lamps are required on newer vehicles.

Tires: minimum tread depth (often 1.5 mm or 2/32 inch) and no exposed cord, cuts, or bulges; dual tires must be matched in size and type; load rating must meet or exceed axle weight.

Mirrors: heavy vehicles require a rear-view mirror system and, on many units, convex mirrors; mirrors must be adjustable and give a clear view behind and to the sides.

Mud flaps and splash guards: required behind wheels on many heavy vehicles to reduce spray and debris.

Exhaust and emissions: exhaust systems must be intact and not leak; emissions control equipment (DPF, SCR) must not be tampered with.

Load limits: axle and gross vehicle weight ratings must not be exceeded; overloading affects braking, handling, and tyre life and is a violation.

Coupling and towing: fifth-wheel, hitch, safety chains, and breakaway systems must be secure and rated for the load; a trailer breakaway brake is required on many trailers.

Warning devices: reflective triangles or warning lights must be carried for breakdowns; placement rules (e.g., behind the vehicle at set distances) apply.

Certificate of Fitness (CF): a periodic inspection document confirming a heavy vehicle meets safety standards (brakes, lights, tires, steering, body); issued after a provincial inspection.

Inspection intervals: typically annual, but some jurisdictions require more frequent inspections for certain vehicle types (e.g., school buses, buses) or after major repairs.

Certificate of Operation: in some jurisdictions, a document or permit required to operate a commercial vehicle or a specific class (e.g., a bus) in addition to the vehicle's fitness certificate.

Pre-trip inspection: the driver must inspect the vehicle before each trip (brakes, lights, tires, fluid levels, coupling) and record defects; a defective vehicle must not be driven.

Post-trip and defect reporting: defects found during or after a trip must be reported and repaired before the vehicle is used again; records must be kept.

Carrier safety rating: commercial carriers are subject to a safety rating based on inspections, collisions, and violations; a poor rating can lead to suspension of operating authority.

Operating authority: carriers must hold the correct authority (e.g., for-hire vs. private) and display required markings; operating without authority is an offence.

Record retention: inspection reports, defect records, and hours-of-service logs must be retained for the period set by regulation (often 6-24 months).

Insurance and registration: heavy vehicles must be registered and insured; proof of insurance and valid registration must be carried and produced on request.
