Michigan Emissions Test Exemptions for Newer Cars

Wondering if your new ride needs a smog check? Michigan emissions testing exemptions for newer vehicles follow a clear set of rules, but they catch many owners off guard. The state only requires testing in 13 counties, and the newest models often skip the process entirely.

Our research shows Michigan requires testing in Wayne, Oakland, Macomb, and 10 other counties as of 2026. The Michigan Department of Environment, Great Lakes, and Energy (EGLE) sets the model year cutoff each year under the state Vehicle Inspection Program (VIP).

Hybrid and newer gas cars still follow county rules.

Do You Need an Emissions Test for a Newer Car in Michigan?

Michigan does not run a statewide emissions program. Testing only applies in 13 Southeast Michigan counties. If you register outside those areas, you will never face a test, regardless of your car’s age.

Inside the testing zone, EGLE uses a rolling exemption. The two newest model years on the road are always skipped. A 2026 model in 2026 is exempt, as is a 2025.

Once a car hits its third model year, it must test every other year until it turns 25.

That means a 2023 car in 2026 faces its first test. A 2022 car tests in 2027. The cycle stays every other year, so owners get a break on off years.

The Michigan Secretary of State (SOS) handles registration and will notify you if a test is required. You can also check your status online through the EGLE lookup tool.

How Michigan's Emissions Exemptions Actually Work

Michigan’s program is called the Vehicle Inspection Program (VIP). EGLE runs it with test sites operated by private vendors. The federal Clean Air Act pushed states like Michigan to reduce pollution in metro areas with poor air quality.

The test itself is an Onboard Diagnostics (OBD) check for most cars. A technician plugs a scanner into your OBD-II port and reads trouble codes. There is no tailpipe probe for 1996 and newer light-duty vehicles.

Exemptions are written into the Michigan Vehicle Code. The two newest model years are skipped by law. After that, the every-other-year rule applies until the vehicle turns 25.

At 25 years and older, the car is considered historic and no longer needs testing.

The 3 Things That Decide If Your Car Is Exempt

Use this simple decision branch:

1. Where you register the car , If your county is outside the 13 testing counties, you are exempt.

, If inside, move to step two.

2. The model year , If it is one of the two newest years, exempt.

, If it is 25 years or older, exempt as historic.

, Anything between faces the every-other-year rule.

3. The powertrain type , Fully electric is exempt everywhere.

, Hybrid follows the same model year rule as gas.

, Diesel under 8,500 GVWR follows the gas schedule.

Here is the logic in plain terms:

• IF county is exempt, THEN no test.
• IF electric, THEN no test.
• IF model year is 2025 or 2026 (in 2026), THEN no test.
• IF model year is 2023 or 2024, THEN test in 2026 if in testing county.
• IF model year is 2001 or older, THEN historic exempt.

Michigan Counties Where Exemptions Don't Apply

Testing is required only in the Southeast Michigan air quality nonattainment area. That covers Wayne, Oakland, Macomb, Monroe, Washtenaw, Livingston, St. Clair, Lapeer, Genesee, Shiawassee, Ingham, Eaton, and Barry counties.

Outside those 13, you will never get a test notice. Rural owners in the Upper Peninsula or Grand Rapids area skip the whole process.

A common issue is students or military members registered at a parent’s address. If that address is in a testing county, the car must comply even if you drive it elsewhere most of the year. EGLE goes by the registered address, not where the car is garaged.

Hybrid and Electric Vehicles: Special Rules

Electric vehicles never need an emissions test in Michigan. They have no tailpipe and no OBD emissions monitors to check. The exemption is automatic at registration.

Hybrids are different. They still have a gas engine and must follow the same model year and county rules as any other car. A 2024 hybrid in Wayne County tests in 2026.

A 2026 hybrid in the same county does not.

Plug-in hybrids (PHEVs) fall under the hybrid rule. The gas engine triggers the test requirement. If you drive mostly on electric, the test is still based on the vehicle’s age and your county.

Step-by-Step: How to Check If Your Car Qualifies

Start with your registration address. If it is outside the 13 testing counties, you are done. No test is required.

If you are inside a testing county, look at your model year. The two newest years are exempt. For 2026, that is 2025 and 2026 models.

For older cars, check the every-other-year cycle. A 2023 model tests in 2026. A 2022 model does not test in 2026 but will in 2027.

Electric vehicles skip the whole process. Hybrids follow the gas car rules.

You can also use the EGLE online lookup tool. Enter your VIN or plate number, and it will confirm if a test is due. The SOS mails a notice if you owe a test, so watch your mail.

What Happens If You Skip the Test by Mistake

You cannot renew your plates without a passing test or valid exemption. The SOS will block the registration until you comply.

If you miss the deadline, late fees start at $10 and climb from there. Driving on expired plates is illegal. Police can ticket you, and the fine is usually $100 or more.

The test itself is quick. Most stations finish in 15 to 20 minutes. If you fail, you get a list of repairs needed.

Fix those, and you can retest for free within 60 days.

Common Mistakes That Cost You Time and Money

Assuming all new cars are exempt is the top error. Only the two newest model years skip the test. A 2024 car in 2026 is not new enough.

Ignoring the county rule is another. If you move from a non-testing county to a testing one, your car may suddenly need a check. The address on file with the SOS is what matters.

Forgetting the every-other-year cycle trips up owners. A 2022 model tests in 2027, not 2026. Mark your calendar so you do not miss it.

Hybrid owners sometimes think they are exempt. They are not unless the car is electric-only. The gas engine means the standard rules apply.

Finally, do not ignore a check engine light. If it is on, you will fail the OBD test. Get it scanned and fixed before your test date.
