Maine requires a safety inspection every year for cars registered in the state, and if the car is registered in Cumberland County it also gets an enhanced check that includes the OBD system on 1996 and newer models. The fee is capped by law at $12.50 for a standard inspection and $18.50 for a Cumberland County OBD inspection. If you buy from a dealer, the car generally has to come with a sticker issued within the past 60 days, which Maine calls a "warranty of inspectability."
I read Maine's inspection statute, Title 29-A chapter 15, on the Legislature's site and the Secretary of State's Used Car Buyer's Guide on Oct. 20, 2026. The statute page said its data was extracted Oct. 5, 2026. I'm not a lawyer, and where the law doesn't say something, I'll tell you that rather than guess.
What the yearly inspection covers
Section 1751 says a motor vehicle that has to be registered in Maine must have an annual inspection. The list of equipment checked covers body components, brakes, exhaust, glass, horn, lights and turn signals, mirrors, reflectors, running gear, seat belts on 1966 and newer cars, steering, tires and wipers, plus the catalytic converter and filler neck restriction on 1983 and newer models.
Cumberland County is the exception. Cars registered there get an annual "enhanced" inspection that adds the fuel tank cap on 1974 and newer gas vehicles and the on-board diagnostic system on 1996 and newer ones. Outside Cumberland County, the OBD check is optional. So if a seller in Portland, which is in Cumberland County, swears the check engine light "is nothing," remember that the OBD system is part of what gets inspected there.
What it costs
The statute sets maximums rather than a fixed price. A station can charge up to $12.50 for the standard inspection, up to $15.50 for a pre-1996 car getting the Cumberland County inspection, and up to $18.50 for a 1996 or newer car getting it. The fee is due whether the car passes or not. Repairs are the real cost, of course, and on an older car with salt damage they can dwarf the fee.
One change coming: a new subsection effective Jan. 1, 2027 lets rental companies with at least 700 noncommercial vehicles registered in Maine get two-year certificates. That doesn't change anything for a private buyer, but you'll see it mentioned in news about "biennial inspections."
Buying from a Maine dealer
The Secretary of State's Used Car Buyer's Guide says used cars sold by dealers generally must have an inspection sticker issued within the past 60 days, meaning the car was inspected and will pass on the day you buy it. Section 1754 of the statute backs that up with the same 60-day window.
The exception is a car posted with an "Unsafe Motor Vehicle" certificate. That means a licensed mechanic inspected it and it failed, with the failed items listed. The guide warns that such a car has to be towed off the lot, can't be test driven on Maine roads and can't get a temporary plate. It's a legitimate way to sell a project car, but the price should reflect every item on that list.
The same guide says Maine has no cooling-off period for used cars bought at a dealer, and that the window sticker must disclose things like prior use, major mechanical problems and fire, flood or collision damage over $2,000 to repair. Our Maine used car lemon law post covers what happens when a car breaks after the sale.
Private sales and cars from out of state
A private sale doesn't carry the warranty of inspectability; the buyer's guide says it covers dealer sales only. I didn't find a grace period in chapter 15 that lets you drive a newly bought, uninspected car for some number of days, so plan on getting the inspection done right away and ask the station or BMV about your exact situation.
Section 1752 has two out-of-state rules worth knowing. A car owned and registered in another state with a valid inspection from that state is exempt. And a car registered in Maine that displays a valid certificate from another state is exempt for one year from the date of that inspection. Antique autos registered as antiques are exempt too. For the paperwork, see our Maine private-sale title transfer guide and the Maine used car sales tax guide.
Fake stickers and unsafe cars
Under section 1768, displaying a sticker you know is fictitious or issued to another car, or one issued without an inspection, is a Class E crime. Driving a car with equipment that doesn't meet the rules is a traffic infraction, and it becomes a Class E crime if the car poses an immediate hazard. If a deal comes with a sticker but the car feels wrong, trust the car.
A fresh sticker also says nothing about the title. Check it on NMVTIS, and if you see a salvage or rebuilt brand, read our Maine salvage and rebuilt title rules first.
CarVins is a licensed CARFAX and AutoCheck reseller and isn't affiliated with either. As of late October 2026, a single report was about $5.50 as a guest or $4.50 as a member, or about $6.75 for both, versus retail of roughly $39.99 to $44.99. The checkout price is the one that counts.
