Display it before you offer the car
The trigger is offering, not selling. Under §455.2(a) the Buyers Guide goes on the vehicle before it is offered for sale, and it must be displayed so that both sides are readable: either both sides visible, or the form attached in a way the buyer can remove and turn over.
Practical consequences on a small lot: a car photographed for online listings but not yet formed is a car being offered. So is a car parked out front with a price on the glass "just to see if anyone bites." Form it when it hits the line, not when a buyer walks up.
The final form goes home with the buyer
§455.3(a) requires you to give the buyer the final version of the window form at the time of sale. Final means it reflects what you actually negotiated: if the as-is box was on the glass and you agreed to cover the transmission for thirty days, the form the buyer takes has to say so.
Two habits make this automatic. Keep the form with the car, so it moves to the desk when the car is sold. And put a copy in the file — the copy is your evidence that what you delivered matched what you promised. It is on the list in the deal jacket checklist.
"Final" also means the form is specific to that vehicle. A stack of pre-printed as-is forms filled in at the desk is how a lot ends up handing a buyer a document describing a different car, or one that contradicts what the salesperson promised an hour earlier. Fill the form when the car is priced, update it when the deal changes, and let the copy the buyer signs be the same version that was on the glass.
If you would rather not hand-fill it twice, the print pack in DealerPronto assembles the buyer's copies as one set at delivery, so the Buyers Guide leaves with the car instead of staying in the drawer.
The sentence that has to be in your contract
§455.3(b) does two things: it makes the window form part of the contract, and it makes the window form override contrary provisions in the contract. It also requires this sentence, in the contract:
Check your own paperwork for it. Utah's standard bill of sale (TC-843) does not contain that sentence — it is a state title-transfer document, not a federal disclosure. If your closing packet is a TC-843 and nothing else, the §455.3(b) sentence is missing from your deal, and the fix is a line in your own sale agreement.
The override direction matters more than dealers expect: an "as-is" window form beats a warranty paragraph buried in the contract, and a warranty checked on the window form beats an as-is clause in the contract. Make the two documents agree before the buyer signs.
Spanish-language sales need Spanish forms
§455.5 is short and strict: if you conduct a sale in Spanish, both the window form and the §455.3 contract disclosures must be in Spanish. The Rule allows an English-language form and a Spanish translation to be displayed together, but it does not allow a Spanish negotiation to close on English-only disclosures.
For a lot that sells in both languages in Utah, that means sourcing genuine Spanish forms, not translating on the fly at the desk. Many form vendors' catalogs are English-only, so confirm the Spanish window form before you need it. State forms are a separate matter — Utah's TC forms are issued in English and you file them as issued.
Who the Rule applies to, and to which cars
The Used Car Rule is written around dealers selling used vehicles to consumers, and each of those three words is a defined term in §455.1 rather than a common-sense one. The practical question for a small lot is the volume threshold: a person who sells a handful of cars a year may fall outside the definition of dealer, while a licensed lot plainly falls inside it.
§455.1 draws the line at volume: a dealer is anyone who sells or offers a used vehicle after selling or offering five or more used vehicles in the previous twelve months; a consumer is anyone who is not a used-vehicle dealer; a used vehicle is any vehicle driven more than the limited use needed to move or road-test a new one before delivery.
Two practical readings hold regardless of where the line falls. If you hold a dealer license, assume the Rule applies to every used vehicle you offer. And if you are not licensed yet but selling cars, the volume question is the same one MVED asks from the other direction — Utah has its own limit on how many vehicles a person may sell without a license, and that is Utah Dealer School's subject, linked below.
Where dealers actually get caught
Four patterns, in rough order of frequency:
- Cars offered without a form — photographed, priced, or parked out front before the Guide goes on.
- One side visible only, with the form taped flat to the inside of the glass so the back cannot be read.
- Stale forms — the glass says as-is, the deal included a promise, and nobody updated the form the buyer took home.
- A contract with no §455.3(b) sentence, usually on lots whose entire closing packet is state title paperwork.
None of this is the same thing as the branded-title disclosure Utah requires on a rebuilt car, which is earlier in the conversation and on a different form — see selling branded-title cars in Utah. If you finance in-house, the Holder Rule notice and the credit disclosures stack on top of everything here; that stack is in buy here pay here in Utah.
Questions dealers actually ask
When does the Buyers Guide have to be on the car?
Before the vehicle is offered for sale — which includes listing it online or pricing it on the lot, not just the moment a buyer asks about it. Both sides of the form have to be readable.
Does the CARS Rule apply to my lot?
No. The FTC's CARS Rule was vacated on 1/27/2025 and withdrawn on 2/12/2026. The Used Car Rule at 16 CFR 455, including the window form and the §455.3 disclosures, remains in force.
I sell in Spanish. Is an English form with a verbal translation enough?
No. Under §455.5, a sale conducted in Spanish requires the window form and the §455.3 contract disclosures in Spanish. An English form may be displayed alongside a Spanish translation, but the Spanish disclosures have to exist on paper.
