Requires used motor vehicles to be inspected prior to any sale

HB 2317 requires sellers of used motor vehicles in Missouri to obtain a new safety inspection certificate immediately before selling the vehicle, regardless of whether the car currently has a valid sticker. This rule applies to most used cars with over 40,000 miles driven in the last three years, though it excludes new vehicles, historic cars, motorcycles, and certain electric or heavy-duty models. The bill also mandates that vehicles sold for junk or salvage do not need an inspection at the time of sale, but they must be inspected again before they can be registered for regular use. Additionally, the legislation updates emissions testing rules by allowing dealers to sell inspected vehicles without an immediate follow-up test for 90 days and clarifies how emissions inspections interact with the standard biennial safety checks.
