Florida does not require smog tests statewide, but some counties do

Florida has no statewide emissions test requirement. However, Broward, Dade, Duval, Hillsborough, Orange, and Pinellas counties require emissions testing as part of vehicle registration. If you live outside these six counties, you will not need an emissions test to register your vehicle in Florida, regardless of your car's age or engine type.

The counties that do test are concentrated in the Tampa Bay area (Hillsborough and Pinellas), the Miami area (Broward and Dade), Jacksonville (Duval), and the Orlando area (Orange). If you are unsure whether your county tests, check your vehicle registration renewal notice — it will say whether an emissions test is required.

Key Takeaways

  • Only six Florida counties require emissions tests: Broward, Dade, Duval, Hillsborough, Orange, and Pinellas.
  • If you live in a county that does not require testing, you do not need an emissions test to renew your registration.
  • In counties that do test, you must pass the test before you can renew your vehicle registration.
  • The test typically costs between $25 and $50 and takes about 10 minutes at an authorized testing station.

How to find an emissions testing station in your county

If your county requires testing, the Florida Department of Environmental Protection (FDEP) maintains a list of authorized emissions testing stations. You can search by county on the FDEP website to find stations near you. Most stations are independent repair shops, quick-lube facilities, or dedicated testing centers.

Call ahead before you go. Some stations book appointments, while others operate on a walk-in basis. Bring your vehicle registration and a valid photo ID. The test itself takes about 10 minutes and involves connecting your vehicle to a machine that reads your emissions data directly from your vehicle's onboard computer.

What happens if you fail the emissions test

If your vehicle fails, you have the option to repair it and retest at the same station or a different one. There is no limit to how many times you can retest, and you do not pay again for retesting at the same station within a certain period — typically 30 days. Keep your failed test report; it documents what needs to be fixed.

You cannot renew your registration until you pass. If your registration expires before you pass the test, you are driving with an expired registration, which can result in a traffic stop and citation. Plan to test at least two weeks before your registration renewal important date to allow time for repairs if needed.

Which vehicles are exempt from testing

Diesel vehicles, motorcycles, and vehicles model year 1996 and older are typically exempt from emissions testing in Florida counties that require it. Some counties also exempt vehicles that are less than two years old. Check your renewal notice or call your county's tax collector's office to confirm whether your specific vehicle is exempt.

If your vehicle is exempt, you will not see an emissions test requirement on your registration renewal notice. You can renew by mail, online, or in person without visiting a testing station.

The cost and timeline for emissions testing

The test itself costs between $25 and $50 depending on the testing station and county. This is a separate fee from your vehicle registration renewal fee. Some stations charge a flat rate; others charge based on vehicle type or engine size. Call ahead to confirm the exact price at your chosen station.

The test takes about 10 minutes once you arrive. If you pass, you receive a certificate or pass notice that you present when renewing your registration. If you fail and need repairs, the timeline depends on how quickly you can get your vehicle fixed and retested — this can range from a few days to several weeks.

Renewing your registration after passing the test

Once you pass, you can renew your registration online through the Florida Department of Motor Vehicles website, by mail, or in person at your county tax collector's office. You will need your passing test certificate or the test station's confirmation number. Online renewal is the fastest option and typically takes a few minutes.

If you renew online, upload a photo of your passing certificate or provide the test confirmation number. If you renew by mail or in person, bring the certificate with you. Your registration renewal fee is separate from the emissions test fee and varies by vehicle type and county.

What to do if you live in a non-testing county but move to a testing county

If you relocate from a county that does not require testing to one that does, you will need to pass an emissions test before you can renew your registration in the new county. Your previous registration from a non-testing county does not exempt you. Plan to schedule a test within a few weeks of moving so you are ready when your registration comes due.

If your registration is not yet due, you can wait until the renewal date to test. However, if your registration expires before you test and pass, you cannot legally drive the vehicle. Contact your new county's tax collector's office for the exact important date if you are unsure.

Frequently Asked Questions

Can I renew my registration online if I need an emissions test?

Yes, but only after you pass the test. You will need your passing certificate or test confirmation number to complete the online renewal. If you have not yet tested, you must schedule and pass the test first.

What if I buy a used car in Florida — do I need an emissions test before I can register it?

If you buy the car in a county that requires testing, yes — you need a passing test before you can register it in your name. If you buy it in a non-testing county and move it to a testing county, you will need to test it before registration renewal. The seller's previous registration does not transfer the test requirement.

Do I have to test my vehicle every year?

Yes, in counties that require testing, you must pass a test every time you renew your registration. There is no multi-year exemption. However, if your registration is valid for multiple years, you only test when you renew.

What if my vehicle is too old to have an onboard computer?

Vehicles model year 1996 and older are exempt from testing in Florida. If your vehicle is older than that, you do not need to test. Bring your registration or title to confirm the model year if the testing station asks.

Can I get a temporary registration without passing the emissions test?

No. You cannot renew your registration without a passing test in counties that require it. Contact your county tax collector's office if you need to discuss a important date extension or hardship situation.
