Time Extension Waiver

The state of Vermont recognizes that emissions repairs not covered under warranty can be costly. There is a time extension waiver available to allow for additional time to bring your vehicle into compliance.

If you have an emissions failure, have your emissions control system diagnosed, and get an estimate to complete the repair. Many emissions component repairs may be covered under your vehicle’s emissions control system warranty. You may be surprised to find out what is covered at no cost to you. The emissions control system warranty differs from the “bumper to bumper” warranty. Contact your dealership to find out more information. Check your vehicle’s owner’s guide or warranty booklet for a contact phone number.

If your vehicle has passed all of the safety components and the emissions repairs are not covered under the emissions warranty, you may qualify for an additional year to complete the repairs. Repairing your vehicle helps to protect our environment and our health by identifying vehicle problems that cause increased air pollutants. Benefits to Vermonters include clean air, improved vehicle performance, and fuel economy, and savings — timely repair of small problems can often prevent more
costly repairs “down the road.”

Time Extension Waiver: What You Need To Know
  • Your vehicle must be ready for the initial OBDII inspection. The Time Extension waiver is not available for the cost associated with getting your vehicle ready.
  • The extension only applies to emissions control components. All vehicle safety defects must be repaired in order to receive a pass sticker.
  • Check your vehicle’s emissions control system warranty. The Time Extension waiver is not available when repairs are covered under warranty.
  • If the estimate to repair your vehicle is under $200, you will have to have your vehicle repaired in order to get a pass sticker. If the estimate to repair your vehicle exceeds $200, or you have spent more than $200 to repair or diagnose your vehicle, you may qualify for a one-year time extension.
  • The Time Extension waiver is good for one inspection cycle. Next inspection, your vehicle must be in safety and emissions compliance in order to receive a pass sticker.
Time Extension Application Check List:
  1. Has the vehicle received an AVIP inspection in 2019?
  2. Does the Fail Vehicle Inspection Report (VIR)indicate that all safety items are a pass?
  3. Does the Fail VIR indicate that the vehicle failed the OBD test?
  4. Does the Fail VIR indicate that the OBD readiness Monitor results are a pass?
  5. Have you had the vehicle diagnosed to determine the cause of emissions problems?
  6. Do you have a written estimate?
  7. Have you checked with a dealership and determined the necessary repairs are NOT covered under your emissions control warranty?
  8. Are the necessary repairs more than $200?

Please review the above checklist. If you’ve answered yes to all of these questions, you may be eligible for additional time to make emissions repairs. Bring your repair estimate to an Official Inspection
Station and ask them about applying for a Time Extension Waiver.

Is there a grace period for Vehicle Inspection?


My vehicle did not pass inspection and it is the last day of the month. What next?

DMV recommends consumers do not wait until the last minute to get an inspection. Customers can take vehicles in for inspection up to two months before the inspection is due. Customers need to work with their mechanic/dealer to get vehicle repaired as soon as possible. Always carry the Vehicle Inspection Report (VIR) in the vehicle, showing that you are working towards compliance.

How do I get my vehicle’s OBD system “ready”?

The vehicle should be driven under a variety of normal operating conditions in order for the OBD system to become ready. These operating conditions include a mix of highway driving and stop and go, city type driving, and at least one overnight-off period. Your vehicle owner’s manual should provide more specific information on getting your vehicle’s OBD system ready. For more information on readiness, please visit: sites/dec/files/aqc/ mobile-sources/ documents/ Readiness.pdf

What if my vehicle’s OBD system is “not ready”?

If your vehicle’s OBD system is not ready, the inspection of the OBD system cannot be completed. While this does not necessarily mean that your vehicle has a problem, it does indicate that your vehicle’s OBD system has not yet completed it’s tests, and problems may be present, but not yet identified. A recently disconnected or discharged (run down) battery, or recent servicing using a scan tool are the most likely reasons for a vehicle’s OBD system being “not ready.” Note that there are a few vehicles which should not be rejected as “not ready”. Ask your inspection station or the Department of Motor Vehicles for further information about these exceptions. 

What are the possible reasons for failing the OBD check?
  1. The vehicle’s OBD system connector has been removed or is otherwise not working properly. The OBD check cannot be completed if the connector is missing or is not working properly. 
  2. The Malfunction Indicator Light does not illuminate at all when the ignition key is turned to the “on” position. When the vehicle’s OBD system detects a problem, it turns on the warning light to alert the driver to a problem. However, if the light cannot illuminate because the bulb has burned out or is otherwise not working, the driver would not be alerted to the problem. 
  3. The Malfunction Indicator Light on the instrument panel is on (and/or commanded on by the vehicle’s on board computer) while the engine is running. This indicates that the OBD system has identified a problem which must be repaired. In this case, one or more diagnostic trouble codes will also be reported by the vehicle’s OBD system and these codes will help your technician diagnose and repair your vehicle. 
What does the OBD check involve?

First, the vehicle is checked to see if the Malfunction Indicator Light (commonly called the “check engine” or “service engine soon” light) on the instrument panel illuminates when the ignition key is turned to the “on” position and then when the engine is running. Next, an electronic device known as a scan tool is connected to the vehicle, and used to communicate with the vehicle’s on board computer. The on board computer is checked to confirm that the vehicle has completed self-tests, to determine if the computer has attempted to turn on the Malfunction Indicator Light, and if applicable, to retrieve diagnostic trouble codes. The results are recorded, and the scan tool is disconnected from the vehicle. The entire OBD check typically takes less than 5 minutes. 

Why is the OBD check needed?

Motor vehicles are the largest source of toxic and ozone-forming air pollutants in Vermont. While modern vehicles are getting much cleaner due to newer engine management technology and emission control components, emissions stay low only when all these systems are working properly. OBD technology helps to ensure that vehicles are operating as designed, and the OBD check ensures that the vehicle’s OBD system is doing its job. 

What is OBD and how does it work?

OBD technology was developed in the 1980s by vehicle manufacturers to help technicians diagnose and service the computerized engine management systems of modern vehicles. A new generation of OBD (often referred to as OBD II) is present on 1996 and newer vehicles. OBD II monitors all components of the engine management system and can detect a malfunction or deterioration of these components usually well before the driver becomes aware of any problem. When a problem is detected, the OBD system turns on a warning light on the instrument panel to alert the driver of the need to have the vehicle checked by a service technician. 

What equipment is needed to inspect OBD Systems?

A scan tool with generic OBD II capability is necessary to perform the required check. A scan tool is a very useful device which is commonly used to assist in the diagnosis and repair of a variety of vehicle problems. Many inspection stations already own scan tools which can also be used to perform the required OBD check, but those inspection stations which do not will need to have one in order to inspect 1996 and newer vehicles. At a minimum, scan tools must be capable of :

  1. automatic initialization with any vehicle,
  2. determining readiness status of OBD monitors,
  3. determining malfunction indicator light status, and
  4. retrieving diagnostic trouble codes.

Any scan tool which complies with Society of Automotive Engineers Recommended Practice J1978 is acceptable. Scan tools are available from a number of well known equipment manufacturers.
