What does the federal odometer law prohibit?

The federal odometer law specifically prohibits driving a vehicle that has a disconnected odometer because this practice undermines the law's purpose of accurately reporting a vehicle’s mileage. A functioning odometer is essential for potential buyers to understand the true wear and condition of the vehicle they intend to purchase. If the odometer is disconnected, it can lead to fraudulent practices where sellers may misrepresent a vehicle's mileage, thereby misleading buyers regarding its value and condition. Ensuring that odometers are properly functioning and accurately reflecting mileage promotes fair practices within the automotive marketplace and protects consumers from potential fraud.

The other options relate to different regulations and responsibilities for vehicle ownership and operation, but they do not directly connect to the federal odometer law, which is specifically focused on the integrity of mileage reporting.
