Vehicle inspection and emissions laws

States that have enacted an annual safety inspection program require vehicles to undergo a multi-point safety inspection that includes safety checks and verifying the functionality of critical components.  Among the components checked are the horn, head and tail lights, plate light, windshield wipers, backup lights, and verifying that window tinting is compliant with state law.

States that have enacted emissions testing programs require consumers to have their exhaust emissions tested to ensure compliance with standards set by the Environmental Protection Agency.
