Ch. 4 Periodic Motor Vehicle Inspection (pp. 68–69)
- Taxis, limousines and rideshare vehicles: PMVI every 12 months.
- Commercial buses and vans: 12 months inside Saskatchewan, 6 months if operating extra-provincially.
- Any vehicle seating 15 or more including the driver: 12 months.
- Power units 22,000 kg or more operating only in Saskatchewan: 6 months; trucks: 12 months.
- Extra-provincial power units 11,794 kg or more: 6 months; trucks: 12 months.
- Trailers, dollies, jeeps and boosters with air brakes: 12 months; LPG, CNG and LNG systems: five years.
- Inspections are done by certified mechanics at certified Vehicle Safety Inspection Stations.
- Carry the certificate in the cab; on semi-trailers keep it in the outside document holder.
- The expiry decal goes on the left window of power units, the right window of buses and school buses, and the left front corner of semi-trailers.
Trip inspection standards (pp. 70–72)
- Trucks and power units over 11,794 kg registered gross weight, buses seating more than 10, and any trailers they tow must be inspected once every 24 hours while in use.
- Schedule 1: trucks, tractors, trailers over 11,794 kg. Schedule 2: buses seating more than 10 including the driver, and trailers towed by a bus. Schedule 3: motor coaches with air ride, air brakes and automatic adjusters.
- Minor defects must be fixed before the next trip inspection; a major defect means the vehicle cannot be driven until repaired.
- The report (paper or electronic) must show the plate or unit number, odometer, carrier, date and time, location, the inspector's printed name and a signed declaration.
- Carry the reports for the current and previous day and the inspection schedule; show them to a peace officer on request.
- It is an offence to drive, or let someone drive, a vehicle with a defective part.
- Before a Class 1–4, G or S road test you name and point out each item and describe what you check, without help or a checklist.
Systematic trip inspection (pp. 73–103)
- Recommended order: engine compartment, exterior, interior, brake response tests.
- Walk counterclockwise from the front down the driver side so you face oncoming traffic; it is sometimes called a circle check.
- Before starting: set the parking brake, shut off the engine, block the wheels (Class 4 lists no blocking).
- Check engine oil cold and never remove the radiator cap; never check belts with the engine running.
- Loose lug nuts can show as rust trails or shiny rings around the nut.
- Brake pedal travel must not exceed 80% of available travel under heavy force.
- Fire extinguisher required in commercial vehicles wider than 2,060 mm; three flares or reflectors if wider than 2,060 mm outside an urban municipality.
- Class 4 (bus 24 or fewer, ambulance for hire, taxi or limousine) has no applicable inspection schedule and a typical taxi has four tires and rims to inspect.
- A Class 2 motor coach has at least eight tires; a Class 3 truck at least ten; a Class 1 combination at least 18.
- Brake response test: with the park brake applied, try to pull ahead gently; then release it, move slowly and apply the foot brake.
- En route checks: tires, rims, lug nuts, hubs, brakes, coupling and electrical connections, lights, load security, leaks; use look, listen, smell and feel.
- Post-trip defects are recorded on the trip inspection report started that day.
- Vehicles 2.06 m (80 in.) or wider need clearance lights (amber front, red rear) and three identification lights (red at rear, amber at front).
