Early 2026 Emissions Testing Updates: What Changed Since January

The first three months of 2026 already delivered more emissions testing upheaval than most full calendar years. New Hampshire tried to kill its inspection program, got blocked by a federal court, lost its vendor, and now sits in legal limbo with no inspections happening at all. Colorado approved 24/7 self-service kiosks and cut its diesel opacity limit in half. Ohio quietly raised its repair waiver threshold by 50 percent. North Carolina is waiting on EPA to drop emissions testing in 18 counties. And Bexar County is gearing up to start testing in November. None of these stories are finished. Most will play out through the rest of the year, which means the rules you follow today may not be the rules you follow in October. This article covers each change in detail, explains what it means for drivers right now, and flags what to watch going forward. If you read our 2025 year-in-review, consider this the sequel. If you skipped it, start here.

New Hampshire: Inspections Suspended, Court Fight Ongoing

New Hampshire is the single most confusing state in the country for vehicle inspections right now. Here is the timeline. The legislature voted in 2025 to end mandatory vehicle inspections as of January 31, 2026. Governor Ayotte signed it. But the state never got EPA approval to remove its emissions testing program from the federal Clean Air Act state implementation plan. Gordon-Darby Holdings, the Kentucky company that had administered the state inspection program for decades, filed a lawsuit in December 2025. On January 27, 2026, U.S. District Court Judge Landya McCafferty issued a preliminary injunction ordering the state to keep the inspection program running. The state disagreed but initially extended the deadline for expired stickers to April 10. Then on February 4, the Executive Council voted 3-2 to deny a contract extension with Gordon-Darby, leaving the state with no approved vendor. On February 13, the Attorney General announced that the inspection program was suspended until further notice. Stations cannot issue stickers. Drivers do not need to get inspections. On March 2, Judge McCafferty denied the state's request to pause her injunction while they appealed. On March 13, Gordon-Darby filed a contempt motion asking the court to impose escalating fines. On March 19, the Attorney General filed a motion with the First Circuit Court of Appeals calling the district court order terminally flawed. The state argues there is no law left to enforce and no vendor to enforce it with. Gordon-Darby argues the Clean Air Act requires the program to continue until EPA approves its removal. For New Hampshire drivers right now, the practical answer is simple. No inspections are required, no stations are issuing stickers, and the state has said enforcement is suspended. But the legal situation is still moving. If the First Circuit sides with the district court, the state could face fines up to $55,000 per day and potential loss of federal highway funds.

Colorado: 24/7 Kiosks, Tighter Diesel Standards, Higher Fees

Colorado made three changes that took effect in early 2026. The biggest for most drivers is the new emissions test fee. Starting with registrations in March 2026, the fee at Air Care Colorado stations is $35, up from $25. That applies to all in-person tests on the Front Range. The second change is new 24/7 self-service emissions testing kiosks. The Colorado Air Quality Control Commission approved these in January 2025, and they are scheduled to roll out during 2026. The kiosks will handle OBD-II diagnostic tests for gasoline and hybrid vehicles, covering roughly 350,000 of the 1 million vehicles that need testing in the nine-county Front Range area. Exact locations have not been announced yet. The kiosks will not be able to test for gas cap leaks, which is a trade-off the state accepted in exchange for convenience. The third change is a stricter diesel opacity standard. The commission cut the allowable smoke opacity for naturally aspirated diesel vehicles from 40 percent to 20 percent measured over five seconds. This brings naturally aspirated diesels in line with the standard that already applies to turbocharged diesel vehicles. If you drive a diesel truck on the Front Range, your margin for passing just got tighter. The state also expanded its compliance tools for catching tampered emission systems, including deleted DPF and EGR setups. Colorado already has the authority under a 2022 law to investigate shops that provide these modifications, and the Air Pollution Control Division is actively using it. Separately, the Regional Air Quality Council launched its Clean Air Auto Repair program in 2025, which provides no-cost emissions repairs for qualifying drivers in the seven-county Front Range area. That program continues into 2026 and covers catalytic converter replacements, oxygen sensors, and gas cap repairs.

Ohio E-Check: Repair Waiver Jumps to $450

Ohio's E-Check program raised its repair waiver threshold from $300 to $450 effective January 1, 2026. This means that if your vehicle fails emissions testing in the seven-county Cleveland area and you want a repair waiver, you now need to show at least $450 in qualifying emissions-related repair receipts before a waiver can be issued. The increase is a direct result of the Cleveland metro area being reclassified from Moderate to Serious non-attainment for ozone under EPA standards. The Ohio Administrative Code ties the waiver amount to the area's non-attainment classification, so the bump was automatic once the reclassification took effect. There is a transition window. Vehicles that took their first test and failed in 2025 are still subject to the $300 threshold through March 31, 2026. After that, and for any vehicle whose first failing test is in 2026, the $450 amount applies. Everything else about E-Check stays the same. Testing is still free. The program still covers Cuyahoga, Geauga, Lake, Lorain, Medina, Portage, and Summit counties. The 21 self-service kiosks are still available 24/7. And the state is still pursuing EPA approval to eliminate the E-Check program entirely, though EPA has not given a timeline for that review. If you are budgeting for repairs on an older vehicle that might fail, plan around the new $450 number. The waiver only counts work done by a licensed repair facility. Self-repair receipts for parts qualify, but you cannot submit your own labor toward the total.

North Carolina: 18 Counties Waiting on EPA

North Carolina is on track to remove emissions testing in 18 of its 19 counties, leaving only Mecklenburg County in the program. The legislature authorized this in the 2023 state budget, and the NC Division of Air Quality submitted a revised State Implementation Plan to EPA on October 1, 2024. EPA has up to 18 months from that submission to review and act, which puts the outside deadline around April 2026. After EPA acts, there will be a 30-day public comment period on the federal side, and then the state needs at least 60 days after certification before the changes take effect. Realistically, the earliest the 18-county removal could go live is mid-2026. The counties that would drop emissions testing are Alamance, Buncombe, Cabarrus, Cumberland, Davidson, Durham, Forsyth, Franklin, Gaston, Guilford, Iredell, Johnston, Lincoln, New Hanover, Randolph, Rowan, Union, and Wake. Mecklenburg County stays in the program because Charlotte remains in ozone non-attainment. However, even Mecklenburg has a narrowing test window. Under the 2023 law, only vehicles with a model year within 20 years of the current year and earlier than 2017 are subject to emissions testing there. That band will shrink every year until approximately 2037, when no vehicles would qualify. For now, all 19 counties still require emissions testing during annual safety inspections. Nothing has changed yet for drivers. But if you live in one of the 18 counties listed above and your car currently needs emissions work, the testing requirement could disappear before your next renewal. Safety inspections in all 100 counties are unaffected.

Bexar County: San Antonio Starts Testing November 1

Bexar County will begin mandatory emissions testing on November 1, 2026. This is not new information if you have been following our coverage, but the Texas Department of Public Safety started actively pushing awareness in January and the details are now final. The test will be an OBD-II inspection at certified stations. The maximum fee is $18.50, which is lower than the $25.50 cap in the existing 17 emissions counties. Gasoline vehicles between 2 and 24 model years old and registered in Bexar County will need to pass before they can renew their registration. Electric vehicles are exempt. You will not need a test until your registration actually comes up for renewal after November 1, so there is no immediate rush. The requirement stems from EPA reclassifying the San Antonio area from Marginal to Moderate ozone non-attainment in October 2022. Under the Clean Air Act, Moderate areas must implement a basic vehicle emissions inspection program within four years, which puts the federal deadline at November 7, 2026. The state set its start date six days earlier. Local mechanics are still preparing. Some inspection stations need to purchase OBD testing equipment in the $7,000 to $9,000 range and get their staff certified as emissions inspectors. If you are a San Antonio driver, the DPS recommends getting your vehicle serviced now to avoid surprises at renewal time. The on-the-ground reality is that Bexar County is going through what Houston, Dallas, and Austin went through years ago. The first few months may be bumpy as stations ramp up capacity.

Smaller Changes Worth Tracking

Vermont ended its Time Extension Waiver program on February 9, 2026. Previously, drivers who failed the OBD emissions test could apply for a one-year waiver if repairs exceeded $200 and were not covered by warranty. That option is gone. If your vehicle fails emissions now, you need to fix it before you can get a sticker. Low-income drivers can still apply to the Automotive Emissions Repair Assistance Program at 802-447-6447. Maryland's fee increases from July 2025 are still catching drivers off guard. VEIP station tests went from $14 to $30 and kiosk tests went from $10 to $26. The historic vehicle exemption also changed from a rolling 20-year window to a fixed cutoff of model year 1999 or older. If you have a 2000 or 2001 model year vehicle that used to be exempt, it no longer is. Georgia updated its model year bands for 2026 registration. Vehicles model year 2024 and newer are exempt, and vehicles model year 2001 and older are now exempt as antiques. The testing window covers 2002 through 2023 model year gasoline vehicles in the 13 Atlanta-metro counties. Across the board, the trend toward digital inspection records, online renewal integration, and self-service testing continues. More states are linking station results directly to DMV databases in real time, which means less paperwork but also less room to delay between failing and dealing with it.
