When Does a Leased Truck Need an 'Operated By' Decal?

Operated By Decal: Common Buyer Questions

What is an "operated by" decal, and when is one legally required?

An operated by decal is vinyl lettering applied to a truck's doors that identifies the motor carrier responsible for the vehicle under its DOT operating authority. Under 49 CFR 390.21, if you lease your truck to a carrier, or lease a truck to operate under someone else's authority, the power unit must display that carrier's legal name or trade name along with its USDOT number in letters readable from 50 feet. The words "Operated by" are required in front of the carrier's name any time another name, such as your own company's or the lessor's, also appears on the truck.

What exactly does FMCSA require to appear on the lettering?

FMCSA lease marking requirements call for the legal or single trade name of the operating carrier and its USDOT number, preceded by "USDOT," printed in a color that contrasts with the background on both sides of the power unit and readable in daylight from 50 feet while the truck is parked. The federal rule sets no minimum letter height, though many carriers and some states use 2 inches as a practical floor. If any other name also appears on the truck, such as your own business name or the lessor's, the carrier's name must be preceded by the words "Operated by." If you're unsure which name belongs on the door, check your lease agreement or ask the carrier's safety department before ordering.

What material holds up best for a decal that stays on year-round?

For lettering that lives outdoors in rain, road salt, and direct sun, Hi-Performance cast vinyl is rated for up to 8 years outdoors and is the better choice for a truck that will stay under one carrier for years. Standard Vinyl, a calendered vinyl rated for 3 to 5 years, is a solid budget option if you expect to switch carriers or repaint within a few seasons. Both materials use air release technology, so installers avoid bubbling when applying lettering across a door seam.

What size should owner operator truck lettering be?

FMCSA doesn't set a minimum letter height, only that the markings read clearly from 50 feet in daylight, so most fleets order lettering sets between 3 and 8 inches tall to keep the carrier name and DOT number readable at a distance. Truck Decals can be produced anywhere from 2" x 2" up to 120" wide x 50" high, so a single order can cover both the required lettering and larger branding graphics for the same door. Measure your door panel before ordering since cab shapes vary between makes and sleeper configurations.

Can I send my own artwork, or do you provide a lettering template?

You can upload existing artwork with your carrier name, DOT number, and MC number already laid out, or we can set custom vinyl lettering using your specified text, font, and color. If you're not sure how to format the layout to meet lease marking spacing and contrast rules, our design team can proof the file before production so it's ready to cut correctly the first time.

How much does an operated by decal cost, and is there a discount for fleets?

Pricing depends on size, material, and cut method, with most single-door lettering sets priced in line with standard vinyl plus any material upgrade you select. Fleets ordering 50 or more sets qualify for tiered pricing through our bulk order stickers program, which lowers the per-unit cost as quantity increases. A one-truck owner-operator and a 40-truck fleet can both order from the same product line, just at different volume tiers.

How fast can I get decals, and how do I install them?

Standard production is 3 business days, with a 1 business day priority rush available if you need a truck back on the road quickly, or a 5 business day saver option if you're planning ahead. Installation is straightforward: clean the door surface, tape the lettering in place along its top edge as a hinge, peel away the backing, then squeegee the transfer tape down from the center outward to avoid air bubbles before peeling the tape off. If you switch carriers later, most of these vinyl materials remove cleanly enough to reletter the same door without stripping paint underneath.
