To title a used car in Missouri you usually need a safety inspection certificate dated within the last 60 days, unless the car is under 10 model years old and has fewer than 150,000 miles. In St. Louis City and St. Louis, St. Charles and Jefferson counties, the car also needs an emissions test, and a private seller there is supposed to hand you a passing one. Despite a lot of confused headlines this year, Missouri did not end safety inspections in 2026.
I checked the Missouri Department of Revenue's inspection page, RSMo 307.350 and the Gateway Vehicle Inspection Program site on Oct. 20, 2026, plus the 2026 bill record for the repeal that almost passed.
The repeal that didn't happen
This is the first thing to clear up, because some sites still get it wrong. In January 2026 the DOR put out a news release correcting reports, which it said were most likely generated by AI, that inspections would end on Jan. 1, 2026. They didn't. Then the House passed HB 1838, which would have ended most routine safety inspections starting Jan. 1, 2027. According to the bill record, it cleared the House 104-43 and a Senate committee, then stalled.
The repeal language came back as amendments to a separate highway bill, SB 1408. Aftermarket Matters reported that on the last day of session, May 15, 2026, the House dropped its amendments and passed the bill without them, so the inspection program survived. Expect the fight again next session. For now the old rules apply.
Who needs a safety inspection
Under RSMo 307.350, inspections are every two years, with even model years inspected in even calendar years and odd model years in odd years. The big exemption, in place since Aug. 28, 2019, covers cars for the 10-year period following their model year as long as they have less than 150,000 miles. Both conditions have to hold. The DOR's help page uses a 2015 car as its example: under 150,000 miles, it's exempt through 2025. Roll past 150,000 at age six and you need one.
That exemption doesn't cover a prior salvage vehicle right after it's been rebuilt. Historic-plated cars, trailers, cars sold for junk or salvage, dealer-to-dealer sales and low-speed vehicles are exempt.
The 60-day clock when you buy
The certificate is valid for 60 days from the inspection date, and you have to present a valid one when you apply for title. So in a private sale, the timing matters. If the seller had the car inspected three months ago, that certificate is dead for your purposes and you'll need a new one. The statute also lets you drive an unregistered car by the most direct route to an inspection station, and from there to a repair shop and back.
Dealer sales get a little more room. If a Missouri dealer had the car inspected within 60 days before the purchase date, the certificate stays good for 90 days from the inspection. Our Missouri private-sale title guide covers the 30-day titling deadline and the paperwork side.
The fee caps are low. The Gateway program's owner page says the safety inspection fee should not exceed $12 and the emissions test should not exceed $24, with one free retest at the same station within 20 business days.
St. Louis-area emissions
Emissions testing covers 1996 and newer gas cars and 1997 and newer diesels, 8,500 pounds GVWR or less, registered in St. Louis City or St. Louis, St. Charles or Jefferson counties. Franklin County dropped out on July 1, 2022. The test runs on the same even-odd schedule, and it's also required any time the title changes hands.
The private-sale rule is the one buyers miss. Gateway says state law requires a private seller to give the buyer a current emissions approval or waiver before the sale, and the buyer then has 60 days from the test date to register. Dealers must sell cars that will pass. If a dealer gives you neither a pass nor a waiver, get the car tested within 10 days or 1,000 miles, and if it fails you can take it back for repairs. Waivers aren't allowed in that case. One caution from Gateway itself: a car sold with a waiver will probably fail its next test too.
New cars are exempt for four model years if they're under 40,000 miles at their first biennial inspection, but you have to file a mileage-based exemption request with DNR before registering. That's not automatic.
What a fresh sticker won't tell you
A safety pass means the brakes, lights and steering met the standard that day. It doesn't flag a salvage history, a hail claim or a rolled-back odometer. Search the title on NMVTIS, and if the title says salvage or prior salvage, read our Missouri salvage and rebuilt title rules before you go any further. Budget for state and local tax with our Missouri used car sales tax post, too.
