People often assume a safety inspection is a shop’s judgment call — that one place might pass what another fails, depending on how they’re feeling that day.
It isn’t. The criteria are set by the province, and a licensed inspection centre works through them. Here’s what’s actually on the list.
Passenger and light-duty vehicles are inspected against Ontario’s Passenger/Light Duty Vehicle Inspection Standard. It’s a published document that specifies what gets examined and where the pass/fail line sits on each item.
That’s the part worth understanding: the measurements aren’t ours. Whether a brake pad is thick enough or a tire has enough tread is defined by the standard, not by opinion. A technician’s job is to measure accurately and report honestly, not to decide where the bar sits.
Pads, shoes, rotors and drums measured against minimum thickness. Callipers and wheel cylinders for operation and leaks. Hoses and lines for damage, corrosion and leaks. The parking brake. Brake fluid condition. The pedal itself for travel and firmness.
This is where most failures happen, and it’s the system nobody should be cutting corners on.
Tie rod ends, ball joints, control arms, bushings and the steering box or rack, all checked for wear and excessive play. Shocks and struts. Springs for damage. Wheel bearings.
These items wear slowly, which is why a vehicle can feel fine to its owner and still be past the limit — you adapt to the change gradually.
Tread depth against the minimum. Sidewalls and tread for cuts, bulges or exposed cord. Uneven wear that suggests something else is wrong. Wheels for damage, and that lug nuts are all present and tight.
Headlights including aim, tail lights, brake lights, signals, hazards, reverse lights, plate light and reflectors. The horn. Wipers and washers. Defroster.
Almost always the cheapest thing on a failure list, and one of the most common.
The whole system for leaks, rusted-through sections, insecure mounting and excessive noise. An exhaust leak isn’t just noise — it’s a route for fumes into the cabin, which is why it’s on the list.
Windshield for cracks and chips, particularly in the driver’s line of sight. Mirrors present and secure. Anything obstructing the view out.
Rust and corrosion, with the focus on structural areas rather than cosmetic surface rust. Doors, hood and trunk latching properly. Bumpers, fenders and anything with a sharp or protruding edge. Seats mounted securely.
This is the section that occasionally ends a vehicle’s road life. Structural rust often can’t be repaired economically.
Every belt for condition, operation and secure anchoring. Retractors and latches working as they should.
Fuel tank, lines and cap for leaks and secure mounting. Coupling devices where fitted.
Just as useful to know. A safety is not a mechanical inspection of the whole vehicle. It generally doesn’t cover:
That last point is the one that costs people money. A safety confirms items are above the minimum today. It doesn’t tell you the brakes are at 15 percent and due in a few months — it just tells you they passed.
If you want that fuller picture, particularly on a vehicle you’re thinking of buying, a pre-purchase inspection is the one that gives it to you.
Only a registered DriveON technician can perform and sign off a safety inspection, working on the inspection tablet, and they must hold a valid Certificate of Qualification with Skilled Trades Ontario. The results go into the province’s system rather than onto a paper slip, which means the inspection is on the record.
If you want to improve your odds, the cheap stuff is worth doing first:
None of that will save a vehicle with real problems, but it does stop you failing on a two-dollar bulb.
