General Information

Multi-Year Registration Testing Requirements NEW

These vehicles are still required to test. Motorists who live in an E-Check county are eligible for multi-year registrations from two-to-five years. E-Check county residents that purchase multi-year registrations must continue to comply with the regular biennial E-Check requirements. Motorists with multi-year registrations that have been issued an extension must comply with the extension requirements in order to maintain valid registration.

E-Check county residents who do not comply with E-Check requirements are subject to registration suspension and confiscation per Ohio Revised Code (ORC) section 4503.103(D).

Self-serve Kiosks

Self-service Emissions Testing Kiosks 

There are self-service On-Board Diagnostics (OBD) II testing kiosks available for public use at 16 of the full-service E-Check station locations. The self-service kiosks can be used by vehicles to receive their initial test. The inspection consists of three easy steps:

1. Scan your Vehicle Identification Number (VIN) barcode, or enter it directly in the screen, and verify or enter other vehicle information necessary.

2. Connect the OBD testing device to your vehicle's data port.

3. Collect your Vehicle Inspection Report showing your vehicle's information and the inspection results. If your vehicle passes, you may proceed with your registration. If your vehicle fails, you must return to a regular inspection lane during normal business hours for your re-inspection.

The self-service kiosk is intended to be open 24 hours a day, 365 days a year to provide motorists with another testing option that fits their schedules.

Note: The availability of the kiosk for testing for the next person, particularly during non-station operating hours, is highly dependent on the proper use of the kiosk by the previous motorists. If a customer does not return and properly reset the bar code scanner and/or DLC diagnostic testing device to the kiosk after use, the kiosk will not be available for use by subsequent customers until a station employee can correct the misuse of the components during regular station operating hours. In this situation, the kiosk will display an "Out of Service" message.

If the "Check Engine" light has been turned off recently (within a week) because the battery was disconnected, vehicle repaired, serviced or the computer was cleared with a scan tool, the vehicle may not be able to receive a test either at the kiosk or an inspection lane. The vehicle may first need to be driven through its drive cycle to ready the vehicle’s computer for testing. You can read the following for additional information on drive cycles and vehicle testing readiness:

If the "Check Engine" light is on, you will still be able to test the vehicle, however, you will receive a failing test. The purpose for this would be to obtain the trouble codes for free which you or your mechanic can use to repair the vehicle. The vehicle is allowed three free tests within a 365-day period. The fourth and any subsequent tests will need to be conducted at a full-service station in an inspection lane and will cost $18 each time.

During normal E-Check station hours of operation, there will be employees available for help with the testing process. 

Testing Information

Anyone can bring the vehicle in for the test. Vehicle registration is not required but is helpful.

Testing frequency and which vehicles need to test

All even-model-year vehicles must be tested during the even-numbered years (e.g. a 2016 vehicle must be tested in 2022, 2024, etc.). All odd-model-year vehicles must be tested during the odd-numbered years (e.g. a 2015 vehicle must be tested in 2021, 2023, etc.). However, you do not need to have a vehicle tested if a previous test was done within one year of your current renewal date. 

An E-Check test is valid for 365 days following the date of the test. You may use that same test certificate to renew your registration if your renewal date falls within 365 days from the initial test. Please keep in mind that vehicles are only required to test every other year.

Vehicles that should test well ahead of their registration date are:

  • Those who spend winter outside of Ohio (test before the winter season)

  • College students attending a school in Ohio that is not located in a testing county

  • Vehicles that may need repairs or have a "Check Engine" light on (test early to allow plenty of time for repairs before your registration renewal date)

All gasoline- and diesel-fueled vehicles, including flexible fuel and hybrid vehicles, equal to or less than 10,000 pounds gross vehicle weight rating (GVWR), 25 years old or newer from the current testing year, and registered in an E-Check county must comply with E-Check. Please refer to the exempt vehicles section below for a list of vehicles that are exempt from the E-Check program.

New vehicles

New vehicles are exempt for the first four model years. For example, 2020 to 2023 model year vehicles are exempt from testing in 2023.

Cost of the test

In accordance with House Bill (H.B.) 119, a motorist may receive up to three free tests within a 365-day period. With the fourth test, and all thereafter, the motorist will be charged a fee of $18, which must be paid at one of the 23 full-service E-Check stations. Only one free passing test is permitted within a 365-day period.

Duplicate test certificates

Motorists can obtain a duplicate copy of a valid passing test record at any of the E-Check testing locations free of charge. The motorist will need to bring the Vehicle Identification Number (VIN) to the testing station.

Vehicles permanently exempt from the E-Check program

Some vehicles are permanently exempt from the E-Check test requirement. The following is a partial listing of permanently exempt vehicles:

  • Vehicles weighing more than 10,000 pounds GVWR (contact Ohio EPA Field Office for appointment)
  • Motorcycles, recreational vehicles and motor homes (contact Ohio BMV for details)
  • Historical and collector's vehicles (contact Ohio BMV for details)

Please visit the exemption/extension website for additional information.

What is the difference between a 'permanent exemption' and owning a vehicle that is permanently exempt?

Vehicles that are eligible for a permanent exemption must make arrangements for the vehicle to have a one-time visual inspection performed by Ohio EPA Mobile Sources field staff. These vehicles include:

 

  1. Electrically powered vehicles (one-time verification inspection by Ohio EPA Mobile Sources Section required.)

  2. Vehicles operating on alternative fuel, such as propane, butane, alcohol or natural gas (one-time verification inspection by Ohio EPA Mobile Sources Section required.)

  3. Non-commercial vehicles weighing more than 10,000 pounds GVWR 

Several types of vehicles are permanently exempt from the E-Check test requirement and do not need a visual inspection. A complete list with a detailed explanation may be found in Ohio Administrative Code (OAC) Section 3745-26-12(c). It is not necessary for vehicle owners that are permanently exempt to be issued an exemption certificate. The most common types are listed below.

  1. Vehicles more than 25 years old, as determined by vehicle model year

  2. Commercial vehicles weighing more than 10,000 pounds GVWR

  3. Historical and collector's vehicles (contact Ohio BMV for details)

  4. Parade and exhibition vehicles (contact Ohio BMV for details)

  5. Motorcycles, recreational vehicles and motor homes (contact Ohio BMV for details)

There may be other circumstances under which you may qualify for an exemption or an extension. If you have questions, contact the Ohio EPA E-Check field office at 330-963-4479 or the Ohio EPA Mobile Sources Section at 614-644-3059.

Title transfers

Whenever a vehicle's title transfers to another individual within one of the seven E-Check counties and that vehicle's emissions test has expired, the vehicle must be tested. Vehicles within the four year exemption period do not test on a title transfer. Vehicles that are 25 years old or newer and were titled out-of-state must also be tested before they are registered in Ohio. If the previous owner has a valid test certificate, the new owner may use it to register the vehicle. In the event the previous owner does not have the certificate or is not sure if the vehicle has been tested in the last 365 days, please click here for vehicle test history. You must have the Vehicle Identification Number (VIN) to obtain this information.

IMPORTANT: An inspection certificate is valid for 365 days following the date of the test. If a vehicle that has undergone a title change is registered within 365 days from a previous test, then the new owner will not need to have the vehicle tested again in order to register. An inspection certificate is valid for one full year from test date, regardless of title changes.

Vehicles not registered in Ohio requesting testing

Any individual seeking an emissions test for a vehicle registered out of the State of Ohio or a vehicle registered in an Ohio county where testing is not mandatory will be required to purchase a voucher in advance for each vehicle to be tested. Testing vouchers can be purchased from Envirotest Systems at full-service E-Check stations for $18 each. Credit cards are not accepted.

Frequently Asked Questions

Which vehicles must be tested?

All gasoline- and diesel-fueled vehicles, including flexible fuel and hybrid vehicles, equal to or less than 10,000 pounds gross vehicle weight rating (GVWR), 25 years old or newer from the current testing year, and registered within an E-Check county must comply with the E-Check requirement. All even-model-year vehicles must test in even-numbered years. All odd-model-year vehicles must test in odd-numbered years.

New vehicles are exempt for the first four model years.

Why does my vehicle need to be tested?

Automobiles are a major contributor to ground-level ozone. In Ohio, the E-Check program is the most cost-effective method of reducing volatile organic compounds (VOCs) and maintaining the required air quality. High pollution levels not only affect the future health of Ohioans, but also make it more difficult to draw new business and create jobs in our communities. The E-Check program will help provide a healthy future and a strong economy for Ohioans and their families.

Why is the Ohio E-Check program important to Ohio's economy?

The E-Check program is a key component of the 10-year maintenance plan to protect air quality while allowing for 10 years of economic growth. With the pollution reductions achieved by the E-Check program, there is more room for new businesses to bring jobs to Ohio and for existing businesses to expand.

What counties are included in the Ohio E-Check program?

The seven Ohio counties currently participating in the program include: Cuyahoga; Geauga; Lake; Lorain; Medina; Portage; and Summit counties.

What type of testing is required for diesel vehicles?

All diesel-fueled vehicles equaling 10,000 pounds gross vehicle weight rating (GVWR) or less must be tested through the E-Check program if they are registered in one of the seven E-Check counties. 

How far in advance can I have my vehicle tested?

An E-Check compliance certificate is good for 365 days, so it is possible to have your vehicle tested up to one year in advance of your registration date. It is often helpful to test early when you know that you or the vehicle will not be in Ohio when it is time to renew. The certificate must be valid through vehicle registration expiration date.

Who can take my vehicle in for a test?

Any motorist may take a vehicle requiring an emission test to the testing station. Ohio EPA recommends that the motorist take the vehicle title or registration to ensure a smooth testing process.

How often will my vehicle need to be tested?

Vehicles are required to be tested every two years. Vehicles with an even-number model year will be inspected in even years. For example, a 2016 vehicle will be tested in 2022, 2024, etc. Vehicles with an odd-number model year will be inspected in odd years. For example, a 2017 vehicle will be tested in 2023, 2025, etc. Since the compliance certificate is good for 365 days, we recommend that you have your vehicle tested far in advance of the registration expiration date.

Do I need to make an appointment before taking my vehicle to a test station?

No. Vehicles are tested on a first-come, first-served basis. No appointments are necessary.

Will I still be able to get my registration by mail?

Yes. Simply mail the emissions test certificate with your renewal notice and registration fee.

What will my vehicle be tested for (tailpipe test only)?

The E-Check tailpipe test measures your vehicle's emissions under various operating conditions. It is designed to measure levels of hydrocarbon (HC), carbon monoxide (CO), and nitrogen oxides (NOx). Vehicles will be required to meet emissions standards established for the year the vehicle was manufactured.

If my vehicle does not pass the test, will the test center make necessary repairs?

The 23 full-service stations do not make repairs, but some of the independent stations that conduct emissions testing also offer repairs. However, not all do, so please make sure you inquire at the station. NOTE: If your testing site does offer repairs, you are under no obligation to use their repair services. You may take your vehicle to an automotive service facility of your choice to have necessary repairs made.

Do I have to pay if my vehicle fails the test?

In accordance with House Bill (H.B.) 119, a motorist may receive up to three free tests within a 365-day period. The fourth test, and all thereafter, the motorist will be charged $18 for the test. Only one free passing test is permitted per 365-day period.

Are there specific repair facilities licensed by Ohio EPA to make emissions repairs?

Ohio EPA licenses repair shops and certifies repair technicians within the seven E-Check counties. Technicians are trained and certified in areas of emission diagnosis and repairs. The technicians must complete a high-quality training program developed by the Training Repair Industry Advisory Group (TRIAG) and Ohio EPA to become Ohio certified E-Check repair technicians. Licensed E-Check repair facilities must employ at least one certified E-Check repair technician and maintain the following equipment:

Reference Materials
DVOM or Digital Multi-Meter
Vacuum Gauge
Fuel Pressure Test Kit
Carbon Cleaner System
3.5 or 5 Gas Analyzer
Scan Tool
Basic Ignition Scope with DIS capabilities

If a vehicle fails the test, the motorist will be given a complete list of all licensed repair stations in the area.

What if my vehicle continues to fail the test?

Motorists are eligible to receive a waiver, depending on the results of repairs performed on failing vehicles. For information on these waivers, please go to our page on Repair Cap Waivers.

Why isn't testing required in all states? In all 88 Ohio counties?

Automobile emissions testing is required in all or part of 33 states to help maintain the federal air quality standard. Areas that were in moderate nonattainment or worse for ozone in 1990 are included in Ohio's E-Check program. These areas include the metropolitan statistical areas of Cleveland and Akron. These areas need to reduce ozone air pollution in order to maintain healthy air quality and to accommodate economic growth. E-Check complements industrial controls in these areas to maintain healthy air quality. Without E-Check, additional requirements could be imposed on industry, limiting the area's ability to attract new jobs and broaden the tax base.

Ohio EPA does not have the authority to implement or require testing of vehicles registered outside the seven counties. Ohio's legislators did not give Ohio EPA the authority to implement an automobile emissions testing program in all Ohio counties.

Why must we test when vehicles are operating more cleanly today than ever before?

It is true – an automobile manufactured in 2020 runs more cleanly than the new vehicles of 1970's. Automobile manufacturers have complied with more stringent emissions standards set by the federal government each year. New emissions devices have improved auto emissions during the past 50 years. However, manufacturers still have no control over routine maintenance of a vehicle once it leaves a showroom.

I had my vehicle tested last year when I purchased it. Why do I have to test it again this year?

When the title of a vehicle is transferred and the new owner wishes to register that vehicle, a passing E-Check test may be required for registration. The vehicle then begins being tested biennially based on model year. In some cases, when a motorist purchases a used vehicle, an emissions test may be required in two successive years. For example, if a 2013 vehicle was purchased in 2020, the motorist would be required to provide a passing test certificate to register the vehicle. In 2021, the vehicle would be required to test again based on the odd model year testing schedule. If the passing test certificate from the 2020 test is more than 365 days old at the time of registration, the vehicle will be required to test again. If the test certificate from 2020 is still valid at the time of registration, the vehicle will not have to be tested in 2021.

My vehicle does not emit smoke and there isn't a spot of rust. Why does it need to be tested?

Many motorists believe that a vehicle which does not emit smoke and has an immaculate paint job is a well-maintained vehicle. Outward appearance of a vehicle is not an accurate indication of how well the vehicle's engine has been or is maintained. The pollutants detected by the E-Check test are odorless, nearly colorless and therefore, undetectable by the naked eye. If a vehicle does not pass the E-Check test, the vehicle is not operating "cleanly" with regard to the harmful emissions. If all emissions repairs are made to a vehicle to bring that vehicle into compliance, the motorist generally experiences an improvement in gas mileage. Proper emissions repairs also lengthen vehicle life.

Regardless of age or mileage, vehicles that are maintained in accordance with manufacturer's recommendations have a better chance of passing the emissions test. Passing the E-Check test indicates that your vehicle's emission control system is operating well, polluting less and consuming less gas.

Call 1-800-CAR-TEST or 1-614-644-3059.

What should you bring to the test, and who can bring the vehicle?

What to bring to the test    

*Anyone can bring the vehicle in to be tested

Ohio title or registration: If your vehicle has Ohio license plates and is registered in an E-Check county the lane inspector may ask for the vehicle title or registration. However, your vehicle can be tested without these items if the vehicle is registered in an E-Check county. If you are moving into an E-Check county, please see the sections below. If you are in the process of purchasing a vehicle and the title is not in your name, a voucher is required to perform the test.

Money: In accordance with House Bill (H.B.) 119, a motorist may receive up to three free tests within a 365-day period.  With the fourth test, and all thereafter, the motorist will be charged $18. Only one free passing test is permitted within a 365-day period. Motorists wishing to obtain a duplicate copy of a valid passing test record will need to bring the Vehicle Identification Number (VIN) to the testing station.

30-day temporary tag: If your vehicle has a 30-day temporary tag, you must present one of the following documents at the time of the test:

  • Ohio title
  • Ohio memorandum of title
  • Ohio lease agreement with the VIN and your Ohio address listed on it
  • Ohio temporary registration

Leased Vehicles: Lease holders must bring the Ohio lease agreement with the VIN and your Ohio address listed on it.

Out of state residents moving into an Ohio E-Check County: If moving into an Ohio E-Check county one of the following processes must be followed in order to have an emissions test done, which will permit you to register a vehicle in Ohio:

  • The owner of the vehicle must go to the title bureau and request the VIN verification inspection only.  The owner will pay $3.50 for the inspection.
    • After the VIN inspection has been completed, the owner will take the vehicle to an E-Check station for testing. The owner will need to present the VIN Inspection Certificate to receive a free test. If the VIN Inspection Certificate is not presented, one of the following must be presented:
      • Ohio title
      • Ohio memorandum of title
      • Ohio lease agreement with the VIN your Ohio address listed on it
      • Ohio temporary registration
    • After passing the emissions test, the owner of the vehicle should return to the title bureau and obtain an Ohio title. The owner can also obtain the required registration from the registrar.
  • Purchase a voucher for $18 at the station or from Envirotest Systems. After completing the registration process, the motorist will be eligible for a refund. 

Ohio residents moving into an E-Check county must bring one of the following:

*Please note that Ohio residents are only required to test if the current year corresponds with your vehicle's normal testing year. 

  • Purchase a voucher at the station or from Envirotest Systems.
    • The voucher must be presented at the time of the test.
    • After your vehicle has passed inspection, you may obtain your new registration and receive a refund for the cost of the inspection. For refund information contact Envirotest Systems Corporation at 1-800-CAR-TEST.
  • New temporary registration showing your new address (30-day temporary tag)

Vehicles from outside Ohio: If your vehicle is titled and registered in another state you must obtain a voucher from Envirotest Systems. The vehicle cannot be tested without a voucher.

No pets: With the exception of service animals in the company of persons with a disability, the test facilities are unable to accommodate animals, including pets. A service animal is defined by the Americans with Disabilities Act (ADA) as "any guide dog, signal dog, or other animal individually trained to provide assistance to an individual with a disability."

 

If you have unanswered questions at the station, please ask for the station manager.

Recently purchase a used vehicle?

If a used vehicle is purchased that requires an E-Check before registration, the owner may transfer plates from their old vehicle to the new one and drive with those plates legally for 30 days. Please keep in mind the three guidelines for transferring standard plates. They are as follows:

  • The vehicle that the license plates were on is no longer owned by you. You have signed the title over to the new owner, salvaged the vehicle, etc.
  • The license plate registration and sticker are still valid.
  • The same person or persons owned both the old and the new vehicle for which the plates are transferring.

Whenever a vehicle's title transfers to another individual within one of the seven E-Check counties and that vehicle's emissions test has expired, the vehicle must be tested. Vehicles within the four year exemption period do not test on a title transfer. Vehicles that are 25 years old or newer and were titled out-of-state must also be tested before they are registered in Ohio. If the previous owner has a valid test certificate, the new owner may use it to register the vehicle. In the event the previous owner does not have the certificate or is not sure if the vehicle has been tested in the last 365 days, please click here for vehicle test history. You must have the Vehicle Identification Number (VIN) to obtain this information.

IMPORTANT: An inspection certificate is valid for 365 days following the date of the test. If a vehicle that has undergone a title change is registered within 365 days from a previous test, then the new owner will not need to have the vehicle tested again in order to register. An inspection certificate is valid for one full year from test date, regardless of title changes.
