In 21 states, no test exists for an ordinary car; in 24 it is the buyer’s problem; in 5 the seller owes it. Which is which, verified.

Inspection rules scare private sellers out of proportion to what they actually require. In 21 states an ordinary car faces no emissions or safety test at all. In 24 a test exists but attaches to the buyer’s registration, not to your sale. Only in 5 states does the seller owe an inspection or a valid certificate as part of a private sale — and those are exactly the rows worth reading before you list the car, because in those states the deal legally cannot close without it.
| State | Seller’s duty | The rule, in one line |
|---|---|---|
| Alabama | No inspection | No emissions programme, no periodic safety test; only the licensing official's counter check, plus a rebuilt inspection after salvage. ↗ |
| Alaska | Buyer’s side | No seller test; an emissions certificate attaches under AS 28.10.271(d) only if the buyer's area is DEC-designated and running a programme. ↗ |
| Arizona | Buyer’s side | Emissions is the buyer's errand at registration in the Phoenix/Tucson areas for non-electric vehicles more than five model years old; results reach MVD electronically (no certificate to hand over), and the seller needs current emissions only when using eTitle Transfer. ↗ |
| Arkansas | No inspection | No smog or safety inspection exists for an ordinary Arkansas sale; DFA's buyer checklist and fee schedules price none. ↗ |
| California | Yes — seller’s job | Seller supplies the smog cert (valid 90 days) for 1976+ gas and 1998+ diesel - but cars under 4 model years and family transfers are exempt. ↗ |
| Colorado | Yes — seller’s job | Seller must hand the buyer an unused passing emissions test if the buyer lives in the Denver metro/North Front Range; first 7 model years exempt. ↗ |
| Connecticut | Buyer’s side | Statewide emissions lands on the buyer: $20 test within 30 days of registering, no reminder sent; no seller test and no result transfers. ↗ |
| Delaware | Buyer’s side | Inspection attaches to Delaware registration, not the sale: the buyer brings the vehicle to the DMV if it needs a Delaware inspection before it can be registered; the seller has no inspection duty. ↗ |
| Florida | No inspection | Florida: no smog or safety test exists for ordinary cars; the only check is a VIN/odometer verification (HSMV 82042) for out-of-state titles. ↗ |
| Georgia | Buyer’s side | Georgia: no safety inspection anywhere; emissions runs in 13 metro Atlanta counties only, as the buyer's registration duty at the tag office. ↗ |
| Hawaii | Yes — seller’s job | No emissions test, but the safety check gates the sale: the county won't record a transfer unless registration and inspection are both current. ↗ |
| Idaho | No inspection | Emissions testing repealed effective 1 July 2023; nothing gates an ordinary in-state sale - only out-of-state or bonded titles need a $5 VIN check. ↗ |
| Illinois | No inspection | Illinois emissions testing program attaches to license plate registration not to title transfer; no inspection gate on the sale itself for any county. ↗ |
| Indiana | Buyer’s side | Emissions testing exists only in Lake and Porter counties and attaches to the buyer's registration, not to the title transfer or the sale. ↗ |
| Iowa | No inspection | Iowa runs no emissions programme and no periodic safety inspection at any age or county; nothing to test before selling. ↗ |
| Kansas | No inspection | Kansas has no safety or emissions inspection requirement for ordinary vehicle sales between private parties. ↗ |
| Kentucky | No inspection | No emissions test anywhere in Kentucky; a sheriff-designated certified inspector checks only vehicles brought in from out of state ($15 fee). ↗ |
| Louisiana | Buyer’s side | Motor vehicle inspection (brake tag) and emissions testing in five ozone non-attainment parishes are registration requirements, not seller duties. ↗ |
| Maine | Buyer’s side | Annual inspection is a registration duty - a private seller owes no fresh sticker; Cumberland County adds enhanced OBD emissions checks. ↗ |
| Maryland | Yes — seller’s job | Cars must pass a State Police-licensed safety inspection before being sold, titled or transferred; the cert lasts 90 days, only 30 on a resale. ↗ |
| Massachusetts | Buyer’s side | No seller duty at all; the buyer needs the $35 annual Massachusetts Vehicle Check within 7 days of the registration date, not of the handshake. ↗ |
| Michigan | No inspection | No emissions or safety inspection requirement for private sales; inspection is not listed among buyer's required documents. ↗ |
| Minnesota | No inspection | No emissions testing or periodic safety inspection; no inspection requirement tied to private sales anywhere in state. ↗ |
| Mississippi | No inspection | No emissions test and no safety inspection in a private sale; DPS inspects only bonded-title cars of 10 model years or less and rebuilt salvage. ↗ |
| Missouri | Yes — seller’s job | Seller gives buyer a safety cert under 60 days old if the car is 10+ model years or past 150k miles; emissions too in St. Louis City + 3 counties. ↗ |
| Montana | No inspection | No emissions program, no periodic safety inspection; the only check is the MV20 VIN inspection by a law officer, not triggered by an in-state sale. ↗ |
| Nebraska | No inspection | No emissions test or safety inspection anywhere in Nebraska; the $10 sheriff VIN check covers out-of-state and salvage cars, not in-state sales. ↗ |
| Nevada | Buyer’s side | Nevada emissions testing applies only in the urban areas of Clark and Washoe counties (1968+, gasoline, GVWR up to 14,000 lbs); it is a registration requirement that lands on the buyer, not the seller. ↗ |
| New Hampshire | No inspection | NH suspended its inspection program on 13 Feb 2026 - no stickers are issued and none required - but an appeal is pending, so the status can change. ↗ |
| New Jersey | Buyer’s side | New Jersey inspection is a registration matter, not a sale matter; the requirements land on whoever registers the vehicle next, and nothing about them stops the seller selling. ↗ |
| New Mexico | Buyer’s side | Bernalillo County only; the buyer's registration needs a valid test certificate and change of ownership triggers one even mid-cycle; none elsewhere. ↗ |
| New York | Buyer’s side | Buyer receives a 10-day inspection extension sticker at registration; no pre-sale inspection required from the seller. ↗ |
| North Carolina | Buyer’s side | Annual inspection is a registration condition the buyer meets; a pass within the last 12 months carries over, and 19 counties add an emissions test. ↗ |
| North Dakota | No inspection | No safety or emissions inspection program at all; only kit builds, modified or salvage rebuilds and no-title vehicles ever need an inspection. ↗ |
| Ohio | Buyer’s side | E-Check runs in 7 northeast counties and attaches to the buyer's registration, not the sale; gas cars 6-25 years old test every two years. ↗ |

| Oregon | Buyer’s side | DEQ emissions test applies only inside Portland and Medford boundaries and attaches to the buyer's registration, never to the seller. ↗ |
| Pennsylvania | Buyer’s side | Buyer must have a used vehicle inspected within 10 days of sale unless it already displays a valid inspection sticker; every post-sale inspection duty PennDOT writes is addressed to the buyer, none to the seller. ↗ |

| South Carolina | No inspection | No smog or safety test exists for a SC private sale; the only check is TI-021B VIN verification when a car has no prior title. ↗ |
| South Dakota | No inspection | No emissions or safety program exists; the manual's only inspection is the $25 rebuilt-vehicle check (Form 1016) - an ordinary sale meets none. ↗ |
| Tennessee | No inspection | Emissions testing ended statewide January 2022 under 2018's Public Chapter 953; no safety program either - no test result touches a sale. ↗ |
| Texas | Buyer’s side | Safety inspections eliminated effective 1 January 2025; emissions required only in 17 counties for buyer. ↗ |

| Wyoming | No inspection | Wyoming: no safety or emissions test at sale; a $10 VIN check applies only to out-of-state titles, homemade/rebuilt/kit cars, or bonded titles. ↗ |
Each row was researched from the state’s emissions and inspection program pages and its seller instructions, then re-verified against the linked source with particular attention to whose duty the test is — the same distinction agency pages are often vaguest about. Metro-area programs (testing only in certain counties) are called out in the row.

Programs get added and retired by legislatures — Washington’s emissions checks ended in 2020 — so the linked source on your state’s row is the thing to confirm the week you sell, not a year later.
