New Hampshire car inspection is no longer required. A 2025 law ended the state’s mandatory annual safety inspection for passenger vehicles as of January 31, 2026, and inspection stations can no longer issue state inspection stickers.1New Hampshire Division of Motor Vehicles. Inspections and Emissions You are still legally responsible for keeping your vehicle in safe operating condition under RSA Chapter 266, and the situation could shift depending on how a federal Clean Air Act dispute plays out.
What Changed and When
The New Hampshire legislature folded the repeal of mandatory inspections into the 2025 state budget. The Division of Motor Vehicles has confirmed that the program is suspended until further notice and that stations are no longer authorized to issue stickers.1New Hampshire Division of Motor Vehicles. Inspections and Emissions
The repeal covers passenger vehicles registered in the state. If you drive a standard car, SUV, or pickup registered in New Hampshire, you don’t need to visit an inspection station or display a valid sticker. Commercial vehicles are a separate matter and remain subject to federal inspection rules.
What Drivers Are Still Responsible For
No sticker requirement doesn’t mean no equipment rules. The safety standards in RSA Chapter 266 stayed in place, and law enforcement can pull you over and cite you for a violation just as before.1New Hampshire Division of Motor Vehicles. Inspections and Emissions The state’s own guidance is direct: drivers must ensure their vehicles meet all safety standards, even without annual inspections.
Common problems that still draw tickets include:
- Broken headlights, taillights, or turn signals
- Worn tires with insufficient tread or structural damage
- Faulty or underperforming brakes
- Exhaust leaks, missing mufflers, or excessive noise
- Windshield cracks that obstruct the driver’s view
What has changed is who catches the problem first. Without a mechanic running through a checklist once a year, thinning brake pads or a slow exhaust leak can go unnoticed until an officer spots it or the part fails outright. A voluntary check at a trusted shop every year or so is still worthwhile.
Window Tint Rules Still Apply
Tint enforcement is separate from the inspection program and hasn’t gone away. After-market tint on the windshield or front side windows can still get you cited during a traffic stop.
If you need darker tint for medical reasons, RSA 266:61-a allows a waiver for after-market tint with at least 35 percent light transmittance on the windshield and front side windows. You apply using Form DSMV 603 signed by a physician within the previous six months, plus copies of your vehicle registration. The waiver covers up to two vehicles, lasts two years, and costs nothing. Renewal requires a new physician signature and application.2NH Division of Motor Vehicles. Tinted Windows
The Federal Clean Air Act Question
The emissions side of New Hampshire’s old inspection wasn’t only a state creation. Because New Hampshire sits within the federal Ozone Transport Region, emissions testing was a required piece of the state’s federally enforceable Clean Air Act State Implementation Plan.3New Hampshire Department of Environmental Services. NHDES Works With EPA to Implement Elimination of the Vehicle Emissions Test Ending the program created a conflict with federal law that hasn’t been fully resolved.
The state is pursuing two tracks with the EPA. It has petitioned under Clean Air Act Section 176A to be removed from the Ozone Transport Region, and it is preparing a State Implementation Plan revision to formally discontinue emissions testing.3New Hampshire Department of Environmental Services. NHDES Works With EPA to Implement Elimination of the Vehicle Emissions Test The EPA has up to 18 months to decide.
Separately, Gordon-Darby, the company that supplied emissions testing equipment to shops across the state, filed a federal lawsuit arguing that ending inspections violates the Clean Air Act. The Department of Safety has acknowledged that it currently lacks the legal authority to run an inspection program because no vendor is approved.1New Hampshire Division of Motor Vehicles. Inspections and Emissions A court ruling or an EPA decision could force some form of testing to return.
If Inspections Return: The Old Rules
The rules below governed the program before it was suspended. They remain on the books under RSA Chapter 266, so if federal action or new legislation restarts the program, this is roughly what you would be looking at again.
Timing
Under RSA 266:1, every registered vehicle other than snowmobiles, mopeds, OHRVs, and roadable aircraft needed an annual safety inspection. Individual owners inspected during their birth month each year. Vehicles owned by companies were assigned a month by the director of the DMV. Newly registered vehicles and vehicles that changed hands had to be inspected within 10 days.4New Hampshire General Court. New Hampshire Code 266:1 – Inspection Authorized The penalty for driving with an expired sticker was a flat $60 fine.5New Hampshire General Court. New Hampshire Code 266:5 – Penalty for Failing to Obey Inspection Requirements
What Was Checked
The technical standards lived in New Hampshire Administrative Rules Saf-C 3200. Inspectors evaluated steering and suspension for excessive play, tested brakes against minimum performance standards, and looked at tires for structural damage and tread depth. Exterior lights, the horn, and windshield integrity were all part of the review; a windshield crack that blocked the driver’s view or interfered with wiper operation was an automatic failure. Vehicles from model year 1996 and newer also went through On-Board Diagnostics testing, and an illuminated check engine light meant the vehicle failed the emissions portion.6Environmental Protection Agency.

Cost
The state charged $3.25 for the physical sticker. Private stations set their own labor rates on top, typically $30 to $60 depending on the shop.
