There is a law that forbids the tampering with, or turning back of, the odometer mileage. This includes both the private citizen and the lot owner. The law also requires that the seller or anyone transferring ownership of the car must provide the buyer with a signed statement indicating the mileage on the odometer at the time of transfer.
