According to federal law, what is unlawful regarding odometer readings?

Federal law defines specific regulations regarding odometer readings to ensure transparency and honesty in vehicle sales. One of the unlawful actions is operating a vehicle with a disconnected odometer. When the odometer is disconnected, it cannot provide an accurate account of the vehicle's mileage, which may mislead potential buyers about the vehicle's condition and history. An accurate odometer reading is essential for assessing the vehicle's value and understanding its maintenance needs.

In contrast, changing odometer readings is also a serious offense, as it constitutes tampering and fraud. While failing to report odometer readings and not providing odometer receipts are issues related to documentation and reporting, they do not inherently misrepresent the vehicle's operational status like operating with a disconnected odometer does. Thus, the focus on the operational integrity of the vehicle and the accurate mileage provided makes the unlawful nature of operating a vehicle with a disconnected odometer a critical federal concern.
