Vehicle emission inspection requirements differ by state or county, but all are determined by an authoritative governing body in response to safety or environmental concerns.

Because vehicles are a major source of pollution, many areas are trying to cut down on pollution as much as possible by requiring emissions inspections.
These inspections help by serving as an effective means of protecting the environment and enhancing air quality. Because emissions inspections are required in many states or provinces, drivers can be fined for riding in a vehicle that either has not had or has failed to pass an emissions inspection. As such, motorists are encouraged to look up the emissions inspection laws of the state or province they reside in or plan to visit an emissions inspection station before they embark on a destination.
