Maine state inspection — once a year, $12.50 at most, and rust holes fail.
Every vehicle that must be registered in Maine needs an inspection every year, at one of over 2,600 stations licensed by the State Police. The law caps the fee at $12.50, unchanged since 2001. In Cumberland County the yearly check adds emissions items, and the cap rises to $18.50 for 1996 and newer cars. A sticker runs to the end of its month a year later. In the month after it expires, police can only give a warning, and after that the fine is $148.

Quick Answer
- How much is a Maine state inspection?
- At most $12.50 for a standard inspection. In Cumberland County's enhanced inspection, the cap is $15.50 for pre-1996 cars and $18.50 for 1996 and newer. The fee is owed whether the car passes or fails.
- Is there a grace period for an expired Maine inspection sticker?
- Sort of. In the first month after it expires, police may only issue a warning, which gives you 2 business days to get inspected. After that, driving without a valid sticker is a traffic infraction; the Violations Bureau schedule lists $148.
- When does a Maine inspection sticker expire?
- One year from the last day of the month it was issued. A sticker issued any day in June expires at midnight on June 30 the next year. The technician marks the month by removing that month's numbered block.

How Maine's Inspection Works
Under 29-A M.R.S. § 1751, a motor vehicle that must be registered in Maine needs an annual inspection, and owners may inspect more often. The State Police Motor Vehicle Inspection Unit licenses over 2,600 stations and 8,000 technicians and sells nearly 1.3 million stickers a year; the program has existed for more than 85 years. School buses are inspected twice a year, and trailers over 7,000 lb GVWR every year.
The sticker goes in the lower left corner of the windshield or in the center behind the rearview mirror (on a motorcycle, on the rear plate). It expires one year from the last day of the month it was issued. Records are on paper: the sticker stub carries the station, date, full VIN, odometer reading and plate, and goes to the State Police.
Maine Inspection Fees
Maximums from 29-A M.R.S. § 1751 and the State Police fee table.
| Inspection | Maximum fee |
|---|---|
| Standard inspection (Class A, up to 10,000 lb) | $12.50 |
| Cumberland County enhanced, pre-1996 | $15.50 |
| Cumberland County enhanced, 1996 and newer | $18.50 |
| Motorcycle | Not more than $12.50 (State Police recommendation) |
| School bus | $8.00 |
| Commercial vehicles | The shop's hourly labor rate |
The caps date from Public Law 2001, chapter 234. The fee is payable whether the car passes or not; stations buy each sticker from the State Police for $2.50. For a Cumberland car built before 1974, the State Police table caps the fee at $12.50.

What a Maine Inspection Fails
From the State Police inspection manual's Class A sequence and BMV's driver manual.
Rust holes
Holes in the body around the trunk or cabin, or in a unibody or rockers. Surface rust passes.
Frame
Broken or rusted so that structural weakness is probable.
Brakes
The foot brake must stop the car within 30 feet from 20 mph.
Tires
Less than 2/32 inch of tread fails.
Glass
Windshield cracks over 6 inches count in the critical vision area.
Airbag light
Fails if it doesn't light up during the self-check (since 2022).
Cumberland County's Emissions Add-On
Since January 1, 1999, vehicles required to be registered in Cumberland County get an "enhanced" inspection every year: the safety check plus a fuel cap check on gasoline vehicles from 1974 and an on-board diagnostic (OBD) check on 1996 and newer models. It's Maine's only emissions inspection. Since January 2001, a car that fails the OBD part must be repaired before it gets a sticker.
The OBD check fails a car when trouble codes are stored and the check-engine light is commanded on. A 1996–2000 car with more than 2 incomplete monitors, or a 2001-or-newer car with more than 1, is "not ready" and has to come back. New cars under 1,000 miles skip the readiness check. Stations in Cumberland County may only do enhanced inspections, so a car from another county inspected there gets one too.
Watch for
- Check engine light on: with codes stored, the car fails.
- Battery just changed: monitors may read not ready.
- A retest: may cost another fee.
- Pre-1974 cars: still get a Class E sticker in the county.

Buying a Car in Maine
A dealer may let a car it sells go on the road only if it meets inspection standards and shows a sticker issued within 60 days of the sale. BMV calls this the "warranty of inspectability": the car should pass inspection on the day you buy it, and Title 10 says the warranty can't be excluded or waived. The dealer must remove any older sticker, and not knowing the car failed is no defense; violations can cost up to $1,000 each.
The exception is a car posted with an "Unsafe Motor Vehicle" certificate, meaning it was inspected and failed. It can be sold without a sticker, but it must be towed off the lot, can't be test-driven on Maine roads and can't get a temporary plate. For a car's title history, BMV points buyers to NMVTIS, in which Maine fully participates.
Before you buy
- "As is": doesn't waive a dealer's inspection warranty.
- A sticker over 60 days old: on a dealer's car, ask why.
- "Unsafe Motor Vehicle": tow only, no test drive.
- Rust holes: fail inspection; surface rust doesn't.
Expired Stickers and Fines
From 29-A M.R.S. §§ 1759 and 1770 and the Violations Bureau schedule for infractions on or after September 24, 2025 (amounts include surcharges).
| Situation | Consequence |
|---|---|
| First month after the sticker expires | A warning only, with 2 business days to get inspected |
| No current, valid inspection sticker | $148 |
| Operating a defective vehicle | $152 |
| Dealer releasing a car that doesn't meet standards | $152 |
| Dealer permitting the sale of such a car | $625 |
| Range set in statute for inspection-rule infractions | $25–$250 |
BMV warns an expired sticker can also cost points on your license. A fictitious or counterfeit sticker is a Class E crime. Police, and designated sheriff, municipal and BMV staff, can issue a permit to drive an uninspected car to a station.
Exemptions
From 29-A M.R.S. § 1752. Motorcycles are not exempt; only antique motorcycles and mopeds are.
Registered in another state
With a valid inspection from that state.
Antique autos
More than 35 years old, on antique plates (over 25 if registered before January 2025).
New cars on dealer plates
Current or previous model year, never registered or titled.
Farm tractors
Exempt from the annual inspection.
Mopeds
And motorized bicycles and tricycles.
New to Maine
A valid out-of-state inspection counts for 1 year after its date.
Failing an Inspection
There's no rejection sticker. A car that fails gets a written list of what's wrong, which also explains how to complain to the State Police; the 2022 rules dropped the old practice of cutting a sticker on a failure. A technician who believes a car isn't mechanically safe must refuse the sticker.
Maine has no waiver or repair-assistance program for inspections, and the manual allows an additional fee for a retest after an OBD "not ready" result. For routine questions or a complaint about a station, the State Police line is 207-624-8935. New residents have 30 days after establishing residency to convert their registration and title.
Bills That Tried to Change It
Every effort to raise the fee caps between 2023 and 2026 failed: LD 900 in 2023 (a flat $20) and LD 566 and LD 667 in 2025. Bills to repeal inspection of passenger vehicles (LD 1242 in 2023, LD 320 in 2025) and to inspect every other year instead (LD 746 in 2023, LD 1010 in 2025) also died. The rules allow for an electronic inspection system if one is ever authorized; none has been.
One change did pass. Public Law 2025, chapter 638 (LD 2191), signed April 3, 2026, lets rental businesses with at least 700 noncommercial vehicles registered in Maine get 2-year certificates from January 1, 2027, with stickers costing twice the usual price. Everyone else still inspects every year. A 2023 law also raised the antique-auto age to more than 35 years.

Maine State Inspection — Frequently Asked Questions
What Maine drivers and buyers ask most.
Do motorcycles need a Maine inspection?+
Yes. Only antique motorcycles and mopeds are exempt. The sticker goes on the rear registration plate.
Does Maine fail cars for rust?+
Rust holes in the sheet metal around the trunk or passenger compartment, or in a unibody including the rocker panels, fail. So does a frame rusted to the point of probable weakness. Surface rust alone doesn't.
I just moved to Maine. When do I need an inspection?+
A car newly registered in Maine that displays a valid inspection from another state is exempt for 1 year after that inspection date. BMV gives new residents 30 days to convert registrations and titles.
Does Maine require emissions testing?+
Only in Cumberland County, where the yearly inspection adds a fuel cap check (gasoline vehicles from 1974) and an OBD check (1996 and newer).
Can a dealer sell me a car without an inspection sticker?+
Only with an "Unsafe Motor Vehicle" certificate, and then it must be towed away. Otherwise the car must meet inspection standards and carry a sticker issued within 60 days of the sale.
Is Maine switching to inspections every two years?+
Not for ordinary drivers. Biennial bills died in 2023 and 2025. From January 1, 2027, only large rental fleets can get 2-year certificates.
