Vehicle inspections began in 1977 with the implementation of the Clean Air Act by Congress. This program required states with high pollution in major cities to undergo vehicle emissions testing. Certain states such as Kentucky and Minnesota recently received permission from the government to opt out of the state inspection program. Some states also implement vehicle identification number inspection programs, typically for the registration of out-of-state vehicles. States with VIN inspection programs include Illinois, Kansas, Nevada, New Mexico and Oklahoma.
