Effective January 1, 2021, all states will be required to capture the odometer disclosures for all vehicles with model year 2011 and forward. As an example, a vehicle with the 2011 model year will not be exempt until January 1, 2031. The 20-year odometer requirement only applies to 2011 model year or newer. Vehicles with a 2010 model year or older remain exempt under the 10-year exemption.
