built to the relevant published spec without scrambling to re-mark a trailer the night before. These trailer identification decals for Ontario operators are sized, worded, and outdoor-rated to satisfy Ontario HTA s.7(3) and FMCSA 49 CFR 390.21 — apply them once and stay compliant.

- Owner name and CVOR number decals in your choice of 3", 4", or 6" letter height
- USDOT number decals for cross-border operators subject to FMCSA 390.21

How It Works
Select your letter height, submit your operator name and registration numbers at checkout, and we print and ship. For trailers over 4,500 kg operating in Ontario, HTA s.7(3) requires characters at least 50 mm tall — our 3-inch option clears that minimum with margin. The 4-inch and 6-inch options suit larger trailers or operators who want greater visibility at distance. Fleet orders are welcome, and per-unit cost drops with volume.
- 3" letter height satisfies the Ontario 50 mm minimum — 4" or 6" for additional clearance or visibility
- Provide your operator name, CVOR number, and USDOT number (if applicable) at checkout
- Apply to a clean, flat surface on the curb side of the trailer — no installer required
- Bulk pricing scales with order quantity for fleet operators managing multiple trailers
Why It Works
Under Ontario HTA s.7(3), a properly applied decal carries the same legal standing as a painted marking — what the regulation governs is character height, legibility, and placement, not the medium. These decals are spec-matched to the regulation, not approximated. The sizing is pre-confirmed against the 50 mm requirement so there is no guesswork at the inspection checkpoint. And because they are Made in Canada with premium cast vinyl, manufacturer-rated for outdoor durability of five or more years, they hold through Ontario winters without peeling, fading, or lifting at the edges.
- Pre-matched to Ontario HTA s.7(3) and FMCSA 49 CFR 390.21 — specs confirmed, not estimated
- Decals meet the same legal standard as painted markings when correctly applied and positioned
- Manufactured with premium cast vinyl, rated for outdoor durability of five or more years, to handle road salt, UV, and Canadian freeze-thaw cycles
- Reduces replacement frequency — and the compliance risk that comes with worn or missing markings
