Some states exempt newer vehicles from emissions inspections. For example, Georgia exempts the three most recent model years from inspection, according to Georgia's Clean Air Force, and California exempts the six most recent model years, according to the California Bureau of Automotive Repair. In some states, such as Virginia and Illinois, only cars garaged in certain counties or zip codes are subject to emissions inspections, as explained by the Virginia Department of Motor Vehicles and the Illinois Environmental Protection Agency.
