Odometer Disclosure — All 50 States
Federal odometer disclosure law (49 U.S.C. §32705) applies to every qualifying vehicle sale in every state. Sellers must certify the actual mileage on the title or a standalone form. Rolling back an odometer is a federal felony carrying up to 3 years imprisonment and a $10,000 fine per violation.
Federal Law — Uniform Nationwide Baseline
49 U.S.C. §32705 sets the minimum disclosure requirement in every state. States may add stricter requirements (California extended the age exemption to 20 years). No state may remove the federal requirement.

How Odometer Disclosure Works
1
Seller Completes Disclosure
The seller (transferor) writes the actual odometer reading on the back of the title or on a separate disclosure form. They certify the mileage is accurate, in excess of the mechanical limit, or that the actual mileage is unknown.
2
Buyer Acknowledges & Signs
The buyer (transferee) signs the same disclosure statement, confirming they received the mileage disclosure. Both signatures are required on most state title forms.
3
Title Agency Verifies
The county tax office or DMV reviews the completed odometer disclosure section before processing the title transfer. Incomplete disclosures cause transfer rejections.
4
Record Retained
A copy of the disclosure is retained by the transferor for at least five years under federal law. The title itself becomes the permanent record after transfer is processed.
Federal Exemptions (When Disclosure Is Not Required)
| Category | Federal Rule | CA Rule | Note |
|---|---|---|---|
| Vehicle Age | 10+ model years old | 20+ model years old (since 2021) | CA extended threshold |
| Vehicle Weight | GVWR over 16,000 lbs | Same as federal | Applies all states |
| Non-Self-Propelled | Trailers, towed vehicles | Same as federal | No engine = exempt |
| New Vehicle Transfer | Manufacturer to dealer | Same as federal | Dealer retail sales not exempt |
| Estate Transfer | Varies by state | No specific exemption | TX: heir exempt; check state |
Exemptions apply only to the federal disclosure requirement. State laws may impose additional requirements even on exempt vehicles (e.g., CA extended age threshold).
