When does a trailer need a yearly safety inspection?

Under Ontario law, a trailer requires a yearly safety inspection (sometimes called a “yellow sticker”) if:

• The trailer’s registered gross weight (RGW) or actual weight exceeds 4,500 kg (9,921 lbs).

This applies to:

• Cargo trailers
• Flatbeds & utility trailers
• Horse trailers
• RV/travel trailers over that weight

• Under 4,500 kg GVWR → No annual inspection required.
• But: they still must be roadworthy (working lights, safe tires, etc.).

• Annual inspections must be done at an MTO-licensed Motor Vehicle Inspection Station.
• Once passed, the trailer is given a yellow Annual Inspection Sticker that must be displayed.

The inspector will check:

• Brakes (if required)
• Tires & wheels
• Lights & reflectors
• Lights & reflectors
• Frame & hitch
• Suspension
• Safety chains
• Overall roadworthiness

• This is enforced under Ontario’s Commercial Vehicle Operator’s Registration (CVOR) program.
