Smog Check and Car Inspection in Virginia
The Virginia Department of Motor Vehicles (DMV) works with the Department of Environmental Quality (DEQ) and the Department of State Police to govern both safety inspections and emissions testing in the state. Read on for more information about these programs, including which vehicles must be tested and how often, where to go for vehicle testing, and what to do if your vehicle fails either inspection.
New Virginia Residents
If you've recently moved to Virginia, your vehicle must undergo a/an:
- Safety inspection: Must be conducted immediately; you can be ticketed for not having a valid inspection sticker on your windshield, regardless of how long you've been in the state.
- Emissions check*: Must be conducted on eligible vehicles before registration (you have within 30 days of moving to the state to register your vehicle).
* Your vehicle doesn't have to undergo an emissions inspection for vehicle registration if it was inspected in a qualifying state within the last 12 months. Refer to Virginia's new resident guide to see if your former state qualifies.
Refer to Completing a Vehicle Inspection below for information on how to have your vehicle inspected for safety and emissions.

Completing a VA Vehicle Inspection

Generally, these official inspection stations display white signs stating as such in blue letters.
For more help finding Virginia state inspection locations near you, contact your local Virginia State Police Safety Division Area Office.
Once you find a station, bring in your vehicle with the applicable fee:

VA state inspection stations provide inspection stickers for your windshield once your vehicle passes inspection.
Failed Safety Inspections
Your inspector will talk with you about why your vehicle failed; it's your responsibility to have the necessary repairs made and have your vehicle reinspected.
Choose from among Virginia inspection stations near you using the state's Emissions Inspection Station Listing and bring:
- Your vehicle registration renewal notice.
- Payment for your fee ($28 maximum).
Once you pass the emissions inspection, you'll receive a Vehicle Emissions Inspection Report; VA inspection stations also report the results electronically to the DMV.
NOTE: If you don't have enough time to have your vehicle inspected before your registration expires, the DMV MAY grant you 1 extension. Contact the DMV at (804) 497-7100 for more information.
Failed Emissions Inspections
You must have your vehicle repaired and retested. You're granted 1 retest for free if you have your vehicle repaired and bring it back for retesting within 14 days.
