Applications & Forms

Emissions testing is performed at certified test stations, which issue a certificate or electronic record used for vehicle registration. No dedicated statewide paper form for exemptions or inspection certificates is published on the cited TDEC page; local county registration offices may require proof of passing or an exemption claim when renewing registration.

Who Must Be Tested and Typical Exemptions

Program coverage (vehicle types, model-year cutoffs, and county applicability) is established by state rules and program notices. The official program page lists counties and program structure; specific vehicle classes and listed exemptions are set on the official TDEC program materials cited below ^[1].

• Common exemptions often include motorcycles, trailers, and certain historic or nonresident vehicles, but the official page should be consulted for exact categories.
