What does DMV odometer disclosure mean?

this just informs the DMV of the actual millage on the vehicle when it was bought or sold. This information is usually saved in a database tied to the DMV database and can be looked by a future potential buyer. So essentially with older vehciles a lot of odometers only read to 99,999 miles then turned over to start over from zero. So this keeps people honest, if the vehicle is bought new then sold at 70,000 miles a person drives it another 70,000 they couldn't sell the car as having 40,000
