Which of the following is a requirement when transferring ownership of a motor vehicle?

When transferring ownership of a motor vehicle, it is essential to provide a written disclosure of the cumulative mileage. This requirement is primarily aimed at ensuring transparency during the sale of a vehicle. A written disclosure serves as a formal record that protects both the buyer and the seller by accurately reflecting the vehicle's mileage at the time of ownership transfer.

This practice is important for several reasons. First, it helps prevent potential disputes over mileage discrepancies, which can significantly affect a vehicle's value and performance. Second, it is a legal requirement in many jurisdictions to document the mileage accurately, often referred to as an odometer disclosure statement. This protects consumers and contributes to fair trade practices within the automotive marketplace.

The other options do not align with the essential legal requirements for the ownership transfer process. Verbal disclosures may not provide the necessary legal protection, notifications to DMV requirements are more comprehensive than simple ownership changes, and immediate registration in the buyer's name is often not a requirement at the time of the sale.
