The short answer

Need just one or two decals — a logo, a patch design, a circle? That's a normal order: send the size, artwork and where it goes.
Lettering and DOT numbers are cut vinyl in solid colors; emblems and multi-color designs are printed decals with an overlaminate.
Commercial trucks: 49 CFR 390.21T requires the carrier's name and "USDOT" number on both sides, contrasting, readable from 50 ft in daylight. It sets no letter height.
Window graphics: Nevada's statutes don't name perforated film; 3M's own exclusions leave fixed rear glass that doesn't block the driver's view — never the windshield or front door glass. Borderline? Ask the DMV or Highway Patrol.
Las Vegas is 3M's warranty Zone 3: its 100, 180, 7125 and 7725 color films carry 3–5 years vertical depending on overlaminate, and no non-vertical period on a hood or roof.

A vehicle decal request is often small and specific: two logos for the doors, a company name and USDOT number on both sides of a truck, a printed emblem for a tailgate, a graphic for the back glass. None of that is a wrap. This guide answers it — with the federal marking rule, Nevada's window statutes and the film makers' own data sheets quoted or closely paraphrased, and every one linked at the bottom so you can check each line.

Cut lettering, printed decals, partials and wraps are different jobs

In general trade practice, cut-vinyl lettering is cut by a plotter from solid-color film, weeded, and transferred to the vehicle with application tape — one color per layer, no gradients. It suits company names, phone numbers and USDOT markings; 3M's bulletin for its ElectroCut 7125 lettering film rates it for cutting and weeding details as small as 0.375 inch. A printed decal is artwork printed onto white film, protected with an overlaminate and contour-cut to shape — the route for anything with full color, shading or fine detail, such as an emblem or a patch design. A partial wrap covers whole panels in printed film; a full wrap covers the painted body. A solid circle can be cut or printed; a multi-color patch design is a printed decal.

Cast or calendered film for a decal

Both are legitimate for decals; they are not interchangeable. 3M's 7125 is a 2-mil cast vinyl whose bulletin lists vehicle graphics among its end uses, rates it for flat surfaces with and without rivets, simple curves and moderate compound curves, and gives an expected performance life of eight years — an unwarranted figure for unprinted film applied to a flat, vertical outdoor surface. ORAFOL's ORACAL 651 is a 2.5-mil calendered film whose data sheet lists car, truck, van and trailer graphics under flat, medium-term applications, with outdoor durability of up to 6 years for colors in vertical exposure, Climate Zone 1. The practical split, reading those two sheets together: ORAFOL lists 651 for flat applications, while 3M rates 7125 over rivets and curves — so a flat door panel can take either, and rivets, body lines and curves point to cast. Neither figure is a Las Vegas figure — see the heat section below.

The removal fine print: most lettering film is permanent

3M's 7125 bulletin lists a "pressure-sensitive, non-removable adhesive" and says of removal: "Not removable. 3M makes no claims as to the speed of removal." ORACAL 651's adhesive is listed as permanent. Printable films such as 3M's 180 series are a different category — its bulletin rates it "removable with heat from supported substrates within the warranty period." If the vehicle is leased, will be resold soon, or the branding will change, say so before the film is chosen. On paint, 3M's Removal instruction bulletin is blunt: 3M does not warrant against damage to paint or clear coats during installation, maintenance or removal; graphics applied before fresh paint has cured are difficult to remove and the paint may be damaged; and repaired surfaces, aged paint and body damage are not considered suitable substrates. 3M's vehicle application bulletin recommends a signed pre-installation inspection record for each vehicle, which is why an installer should look at the paint before quoting the install.

USDOT numbers and company name: what the federal marking rule (49 CFR 390.21T) requires

The marking rule in force is 49 CFR 390.21T — eCFR shows the untagged 390.21 as suspended indefinitely, and the T section carries the same marking text. It applies to every self-propelled commercial motor vehicle subject to the Federal Motor Carrier Safety Regulations. Under 49 CFR 390.5T, that means a vehicle used in interstate commerce with a gross vehicle or combination weight rating (or actual weight) of 10,001 pounds or more, or one designed or used to carry more than 8 passengers (including the driver) for compensation, more than 15 passengers (including the driver) not for compensation, or placarded hazardous materials. The marking must show the carrier's legal name or a single trade name as listed on its FMCSA registration (Form MCS-150), and the FMCSA identification number "preceded by the letters 'USDOT.'" If another company's name appears on the vehicle, the operating carrier's name must be preceded by the words "operated by." The marking must appear on both sides, in letters that contrast sharply in color with the background, be readily legible during daylight hours from 50 feet while the vehicle is stationary, and be maintained so it stays legible. It may be painted or a removable device, if that device meets the same requirements. What the rule does not set: a letter height, a font or a color. Letter size, weight and spacing are design choices made to pass the 50-foot test. Whether your vehicle is covered is a question about your operation, not the decal. The definition reads vehicle by vehicle — weight rating, passengers, hazardous materials, interstate use — so a mixed fleet can have trucks it covers and pickups it doesn't. Carriers that operate only inside Nevada should confirm the state's requirements with their compliance contact. Copy the name and number exactly as your registration shows them.

Window graphics on a vehicle: what Nevada law and 3M allow

Nevada has two statutes that matter here. NRS 484D.440 bars placing any transparent material that alters the color or reduces the light transmission of the windshield or any side or rear window, with three exceptions relevant here (the statute also covers pre-1993 vehicles, factory-installed material and exemptions set by the DMV Director): the windows immediately left and right of the driver, if nonreflective and at least 35 percent total light transmission (tolerance 7 percent); side windows behind the driver and the rear window, if the vehicle has outside mirrors on each side that show the driver the highway at least 200 feet to the rear; and a band at the top of the windshield whose bottom edge sits at least 29 inches above the driver's seat, measured as the statute describes, and is not red or amber. NRS 484D.435 separately bars any sign, poster or other nontransparent material on the windshield, side wings or side or rear windows that obstructs the driver's clear view, except within a 6-inch square in the windshield's lower corner farthest from the driver, and except material federal or state law requires on a window. Neither statute names perforated window film, and the mirror exception in 484D.440 is written for transparent material — a printed perforated graphic may instead be read as nontransparent material under 484D.435, which has no mirror exception. That question is for the state, not for us. 3M's own restrictions narrow it further: its 8170 perforated film is recommended for "non-regulated vehicle windows"; must not go on substrates with built-in heating or defrosting elements or wipers; and on vehicle window exteriors must be laminated with an optically clear overlaminate, or the view can be impaired when the film is wet. 3M's vehicle bulletin adds: no perforated film on windows that crank or roll down, emergency exits or rubber gaskets, or wherever a driver's view will be obstructed or local laws prohibit it. A solid logo or lettering on glass is a different case from perforated film: it is nontransparent material, so NRS 484D.435 is the statute in play — it may not obstruct the driver's clear view — and 3M's 8170 bulletin cautions that glass covered by high-opacity or dark-colored film absorbs more heat, that the thermal stress can break the glass, and that 3M does not recommend such film on glass with significant sun exposure — worth weighing on a dark logo for back glass in Las Vegas. What narrows the choice in practice is 3M's own list: with windshields, wiper glass, defroster glass, roll-down windows and anything obstructing the driver's view ruled out, what remains is fixed rear or rear-side glass — and only where the graphic won't obstruct the driver's clear view. Not the windshield or the front door glass. This is what the documents say, not legal advice; if a window is borderline, ask the Nevada DMV or the Highway Patrol before you buy the graphic.

Las Vegas heat: what the warranty tables say about a decal

3M's Desert Southwest Region document names "Clark (Las Vegas)" among the counties with reduced warranty coverage, which puts Las Vegas in Zone 3 of its MCS warranty matrices. In the January 2025 matrices, the transportation row covering 3M's 100, 180, 7125 and 7725 films in colors reads 6 years with no protection and 7/2 with the best overlaminate in Zone 2 — but 4 and 5 in Zone 3. White and black read 5 and 6 in Zone 3. 3M's legend says a box with one number has a vertical exposure warranty period only, and defines vertical as a graphic face less than 15 degrees from vertical. So in Las Vegas, a decal on a hood, a roof or the flat top of a tailgate carries no non-vertical warranty period on those films at all. Avery Dennison's warranty bulletin colors southern Nevada, Clark County included, as its Zone 3, which cuts warranty length by 60 percent, with a further 20 percent off for non-vertical surfaces (which Avery defines as 10 to 45 degrees from vertical) and the two reductions added together; horizontal applications, it says, are not warranted unless a product's data sheet says otherwise. Two practical notes: these are warranties that a qualified graphics manufacturer extends, so ask any shop whether your graphic will be registered and under which film and overlaminate; and 7125's application range of 50°F to 100°F for flat surfaces is air and substrate temperature, so in a Vegas summer where and when the install happens is part of the plan.

After the install, and what to send for a quote

3M's vehicle bulletin sets the aftercare: keep the vehicle above 60°F for at least 12 hours, do not wash it for 24 hours, then hand wash or use a touchless wash, and never aim a high-pressure spray at film edges. It also warns that car wax greatly reduces graphic adhesion, so skip the wax before an install. For a quote, send: the vehicle year, make and model, or a photo of the panel; the decal size and quantity; where each one goes (door, tailgate, glass) and whether that surface is vertical or a hood, roof or other flat top — it changes the warranty; your artwork, as vector files where possible (our artwork file-specs guide is linked below); whether it includes DOT markings, with your legal name and USDOT number exactly as registered; and whether the vehicle is leased or has any repainted panels. That list answers the questions this page raises — film type, removability, surface and law — before anyone prices the job.

Decal, perforated window graphic, partial or full wrap — which job is yours
Cut-vinyl lettering — names, phone, USDOT numbers, simple logos	Solid colors, one per layer. Common premium film (3M 7125) is rated "not removable" — plan it as permanent.
Printed decal — emblems, patch designs, gradients, photos	Full color on white film, overlaminated and contour-cut. Printable films like 3M's 180 series are rated removable with heat within the warranty period.
Perforated window graphic	Image outside, see-through inside. Fixed rear or rear-side glass only in practice: 3M rules out wipers, defrosters and roll-down windows, and NRS 484D.435 bars anything that obstructs the driver's clear view.
Partial wrap — full doors, sides or rear	Printed film covering whole panels. More material and labor than decals, less than a full wrap — see the vehicle wrap cost guide.
Full wrap	Every painted panel covered. The heat and removal notes above apply to the whole vehicle.

Frequently asked

Can I order just one or two vehicle decals?

Yes. Spot decals are on our vehicle graphics service list. Send the size, quantity, artwork and where each decal goes on the vehicle, and say whether the design is solid colors or full color — that decides cut vinyl versus a printed decal.

Do I need a USDOT number on my truck?

That depends on your operation, not the decal. 49 CFR 390.21T covers self-propelled commercial motor vehicles subject to the federal motor carrier rules; 49 CFR 390.5T defines those vehicle by vehicle, including interstate vehicles rated or weighing 10,001 pounds or more. If it applies, you need your legal or single trade name plus "USDOT" and your number on both sides.

How big do DOT number letters have to be?

The federal rule sets no letter height. It sets a test: the marking must contrast sharply with its background and be readily legible in daylight from 50 feet while the vehicle is stationary. Size, weight and spacing are chosen to pass that test on your vehicle.

Can USDOT markings be a magnet or a removable decal?

Yes, under 49 CFR 390.21T(d) the marking may be painted or a removable device, as long as the device meets the same identification and legibility requirements and is maintained so it stays legible.

Is perforated window film legal on a car in Nevada?

Nevada's statutes don't name it. NRS 484D.440 allows transparent material on the windows immediately left and right of the driver only if nonreflective and at least 35 percent light transmission (±7), and on rear windows when the vehicle has outside mirrors on both sides; NRS 484D.435 bars nontransparent material on any window that obstructs the driver's clear view. 3M rules out windows with wipers, defrosters or that roll down, so fixed rear glass that doesn't block the view is what's left. This is not legal advice — for a borderline window, ask the Nevada DMV or Highway Patrol first.

Will a vehicle decal damage my paint?

The documented risk sits mostly at removal. Common cut-lettering film is rated permanent — 3M's 7125 bulletin says "Not removable" — and 3M does not warrant against damage to paint or clear coat during installation, maintenance or removal. Repainted or damaged panels are the real risk; flag them before the job.

How long will a vehicle decal last in Las Vegas?

Shorter than the brochure. 3M's Zone 3 matrix, which covers Clark County, gives its 100, 180, 7125 and 7725 color films 3 to 5 years depending on overlaminate (4 with none, 5 with the best), vertical surfaces only; the same films read 6 and 7/2 in Zone 2. On those films, non-vertical surfaces carry no warranty period in Zone 3.
