Emissions Inspections
This page explains what to do if your vehicle needs an emissions inspection, but you cannot complete it by the required deadline. It covers extensions, exemptions, and temporary registration options, and explains your next steps.
Maryland law requires most vehicles to pass an emissions inspection when notified by the Motor Vehicle Administration (MVA). If you are unable to complete testing on time, you may qualify for limited relief.
Start Here: Do You Need an Emissions Inspection?
You must complete an emissions inspection if the MVA sends you an official notice.
You may need extra time or an exception if:
- Your vehicle is out of state
- Your vehicle is not operable
- You are unable to access an emissions testing station before your deadline
- You are waiting for repairs or parts
If you are unsure, check your notice or contact the MVA before your due date.
Option 1: Request an Emissions Inspection Extension
An extension gives you more time to complete your emissions inspection.
You may request an extension if:
- You cannot complete testing by the due date listed on your notice
- Your situation meets MVA extension criteria
Extensions are not automatic and must be approved by the MVA.
How to request an extension
- Follow the instructions on your emissions notice, or
- Submit your request through the method specified by the MVA
If approved, your new deadline will be provided by the MVA.
Important: An extension does not waive the inspection requirement.
Call to action:
Request an emissions inspection extension through the MVA
Option 2: Emissions Inspection Exemptions
Some vehicles may qualify for an exemption from emissions testing under Maryland law.
Examples may include:
- Certain vehicle types
- Vehicles that meet specific statutory criteria
Exemptions are determined by the MVA and may require documentation.
What to know
- Not all vehicles qualify
- Approval is required
- Supporting documents may be requested
Call to action:
Contact the MVA to ask whether your vehicle qualifies for an exemption
Option 3: Temporary Registration While Resolving Emissions Issues
A temporary registration may allow limited vehicle operation while emissions requirements are being addressed.
Temporary registration is not guaranteed and is issued only if eligibility requirements are met.
Important notes
- Temporary registration does not replace emissions compliance
- Additional fees may apply
- Expiration dates are strictly enforced
Call to action:
Review temporary registration options with the MVA
If Your Vehicle Is Out of State
If your vehicle is located outside Maryland:
- You may still be required to comply with emissions requirements
- Special instructions may apply depending on location
Do not ignore an emissions notice because your vehicle is out of state.
Call to action:
Review emissions testing instructions for out-of-state vehicles
What Happens If You Do Nothing
Failure to complete emissions requirements by the deadline may result in:
- Registration issues
- Inability to renew registration
- Additional fees or penalties
Always contact the MVA before your due date if you need help.
