What to know about odometer exempt sales in Arizona
Under 49 CFR § 580.17, vehicles that are 10 or more model years old are exempt from federal odometer disclosure. You still must not knowingly falsify mileage. Even if federally exempt, some states have their own mileage disclosure requirements — document the known odometer reading in the bill of sale regardless.
What to include in your bill of sale
- Full legal names and addresses for both buyer and seller.
- Trailer make, model, year, VIN, and current mileage.
- Agreed sale price, payment method, and transaction date.
- Any odometer exempt-specific disclosures required in Arizona.
Seller guidance
Under 49 CFR § 580.17, vehicles that are 10 or more model years old are exempt from federal odometer disclosure. You still must not knowingly falsify mileage. Even if federally exempt, some states have their own mileage disclosure requirements — document the known odometer reading in the bill of sale regardless.
Buyer guidance
While the seller may not be legally required to provide a federal odometer statement, you should still request the actual mileage and note it in the bill of sale. High-mileage vehicles command lower prices, so confirming the reading protects you from misrepresentation claims later.

49 CFR § 580.17 exempts vehicles 10 or more model years old from the odometer disclosure requirement of the Motor Vehicle Information and Cost Savings Act (49 U.S.C. § 32705). Gross-weight exemption applies to vehicles with a GVWR exceeding 16,000 lbs. Despite the federal exemption, knowingly falsifying mileage on any document is still fraud under 49 U.S.C. § 32709.
