Odometer Disclosure Statement: What It Is & What to Write

A vehicle's mileage is one of the most commonly falsified facts in a private sale. Federal law exists specifically because of this — and it requires a written odometer disclosure on nearly every vehicle sale in the United States. Here's what it actually says, what you need to write, and what happens when you get it wrong.

What is an odometer disclosure statement?

An odometer disclosure statement is a written record — signed by both seller and buyer — that documents the vehicle's mileage at the time of sale. It has to include the exact reading, the seller's statement that the reading is accurate (or, if it isn't, why not), and both parties' signatures.

In most states, the odometer disclosure is part of the bill of sale. In others, it's a separate line on the title's assignment section. Either way, it's legally required — not optional — and a DMV clerk will reject a transfer that's missing it.

The federal law behind it: 49 CFR §580

The requirement comes from the federal Motor Vehicle Information and Cost Savings Act, now codified at 49 CFR Part 580 — commonly called the Federal Odometer Act. NHTSA (the National Highway Traffic Safety Administration) enforces it, and it applies to every motor vehicle sold in the United States except the specific exemptions below.

The rule matters for one practical reason: it means that if a seller lies about mileage, they've committed a federal offense, not just a civil contract dispute. Falsifying an odometer disclosure carries fines up to $10,000 per violation and potential criminal liability under 49 U.S.C. § 32709.

The 2021 update most templates miss

Since January 1, 2021, federal rules (49 CFR 580.17) exempt a vehicle from model year 2011 or newer only 20 years after January 1 of its model year, instead of 10. Model-year-2010 and older vehicles stay exempt under the old 10-year rule, so the first model year to drop out under the new rule is 2011, on January 1, 2031.

Some free templates online still reflect the old 10-year rule. If you're selling a model-year-2011 or newer vehicle, an odometer disclosure is required.

Vehicles exempt from the odometer disclosure requirement

Federal law exempts a few categories. If your vehicle falls into one of these, disclosure is not legally required — though many states recommend it anyway as good practice:

• Vehicles of model year 2010 or older — and, from 2031, each later model year 20 years after January 1 of its model year
• Vehicles with a GVWR over 16,000 lbs — heavy trucks and commercial vehicles
• Vehicles not self-propelled — trailers, for example

State rules can add to the federal requirement, so check your state page as well.

What the odometer disclosure must include

Under 49 CFR §580.5, a complete odometer disclosure must contain all of the following:

The three certification options — and when to use each

The accuracy statement is where people get confused. You're not just writing down the number — you're certifying which of three situations applies. Here's what each means:

Option 1: "The odometer reading reflects the actual mileage"

This is the standard certification for a vehicle with a functioning odometer that hasn't been tampered with. You're saying: the number on the dash is accurate. This is what the overwhelming majority of private sales will use.

Option 2: "The odometer reading exceeds its mechanical limits"

Some older odometers only go to 99,999 miles and then reset to zero. If the vehicle has gone over that limit, you check this box. A buyer seeing 30,000 miles on a vehicle that has actually done 130,000 or 230,000 needs to know. This protects both of you — the seller from fraud liability, the buyer from an expensive surprise.

Option 3: "The actual mileage is unknown"

Reserved for vehicles where the odometer is broken, has been replaced and not calibrated to the previous reading, or where there's documented evidence of tampering. This is a significant disclosure — it will affect the vehicle's value, and a buyer can use it as a negotiating point. Never check this option as a shortcut if the mileage is actually known.

Where the odometer disclosure goes on the paperwork

Depending on your state, the disclosure lives in one of two places:

• On the title itself. Most state titles have an assignment section on the back that includes an odometer disclosure box. If your state uses this format, the title assignment and the odometer disclosure happen at the same time — the seller fills in both, signs, and hands over the title.
• On a separate bill of sale or disclosure form. Some states require a separate document — either a standalone odometer statement or a bill of sale that includes the disclosure language. In these states, you bring both the signed title and the signed bill of sale to the DMV.

The DMV bill of sale guide covers which states use their own forms (Texas 130-U, California REG 135, New York MV-912 and DTF-802, and others) — check whether your state's form includes the odometer disclosure.

What happens if the odometer disclosure is wrong?

If it's a genuine mistake

Transposing a digit in the odometer reading is the most common error. If you catch it before the transfer is processed, the fix is simple: cross out the error, write the correct number, and both parties initial the correction. If you've already submitted it to the DMV, you may need to file a corrected disclosure — most states have a process for this.

If it's intentional fraud

Odometer fraud is a federal crime. Under 49 U.S.C. § 32709, a person who violates the odometer disclosure requirements can be held civilly liable for three times the amount of actual damages or $10,000 — whichever is greater — plus attorney fees. Criminal penalties apply for willful violations.

From a buyer's perspective: if you later discover the mileage was misrepresented, the signed odometer disclosure is your primary piece of evidence. It's exactly what makes the disclosure valuable as a document — not just a bureaucratic requirement.

Common odometer disclosure mistakes to avoid

• Writing approximate mileage — "around 95,000" or "95K" is not compliant. Write the exact number.
• Leaving the accuracy statement blank — the disclosure is incomplete without checking one of the three certification options.
• Using a template that doesn't include disclosure language — especially templates written before 2021 that only cover vehicles under 10 years old.
• Signing before both parties are present — in notarization-required states, pre-signing voids the notarization.
• VIN from memory or the dashboard plate — always copy it from the title. The title VIN is the authoritative one.

Does the buyer need to sign too?

Yes. Under federal law, the buyer must also sign the odometer disclosure. This is often skipped on informal handwritten bills of sale — and it's one of the five most common reasons a DMV clerk sends a transfer back. Both parties sign, both parties date it.

How to get a bill of sale with the correct odometer disclosure built in

The safest approach is to use a generator that includes the full §580 disclosure language by default — not a blank template you fill in by hand. Our car bill of sale generator includes the updated 20-year rule odometer disclosure with all three certification options, auto-formats the vehicle details and VIN, and produces a typed PDF that's legible at the DMV counter.
