There is no emissions testing required for vehicles in South Carolina, but residents should be aware of standards in other U.S. states. A smog test is required if a resident moves from South Carolina to another state in the future.

In Nevada, cars that are model year 1975 and older are not required to get a smog check. So if you're driving an old clunker, you're in the clear! However, all cars that are model year 1976 or newer must get a biennial smog check. That means that every two years, you'll need to bring your car in for a test.
