High-impact exceptions

• DC DMV does not require a safety inspection for private passenger or light-duty vehicles; commercial, taxi, and limo vehicles remain inspected under their own programs.
• The brand-new passenger vehicle already has DC's four-year new-car inspection sticker. No physical emissions inspection is due until that sticker expires.
• A brand-new passenger-class vehicle with a manufacturer's certificate of origin is not physically taken through emissions inspection. DC DMV issues a four-year new-car inspection sticker at registration.
• DC titling/registration procedures enumerate the complete document set with no VIN inspection or physical identity step for the ordinary vehicle or transaction.
