Smog Check in PennsylvaniaPage Overview
Pennsylvania Emissions & Vehicle Safety InspectionsCar and truck emissions cause about 33% of the state's air pollution. Because of this, the Pennsylvania Department of Transportation (PennDOT), in conjunction with the Department of Environmental Protection, have authored a comprehensive emissions inspection program designed to improve the state's air quality.
While the vehicle emissions program applies to only certain regions within Pennsylvania, the vehicle safety inspection program applies to the entire state.
On this page you'll find an overview of the Pennsylvania emissions testing program and safety inspection requirements.
The state requires many vehicles to undergo smog checks once a year before their registrations can be renewed.
To let you know when your time is up, the Pennsylvania DOT will generally stamp on your vehicle's renewal notice the words "Emissions Inspection Required/Diesel Vehicles Exempt."
The vehicles that must be tested and the emissions test that need to be performed will vary by county. Please contact the Pennsylvania Department of Transportation (DOT) for more information.
You can have your vehicle tested at any PennDOT-approved service station, dealership, or neighborhood garage.
For a complete list of emissions testing stations near you, please visit the Drive Clean Pennsylvania website.
The cost for an emissions test varies with each station, so you're encouraged to call ahead to find out the price.
If Your Vehicle Fails the Emission Test
Should your vehicle not pass, you must foot the bill for all repair costs needed to bring it into compliance. You then must have it retested before your vehicle's current safety inspection expires. You won't be charged for this second test as long as you return to the same inspection station.
If your vehicle fails a second time, you are eligible for a waiver provided you present proof that you spent over a certain amount on emission repairs. Check with your inspection mechanic to explore your options.
Emission Test Vehicle Exemptions in Pennsylvania
Some vehicles fall under a sort of "basic exemptions" category. Those vehicles include:
- Registered antiques, street rods, and collectibles.
- Vehicles registered in any of the non-emissions testing counties.
Other vehicles are exempt due to their eco-friendly status. Read on.
Before you can renew your vehicle registration, your vehicle must pass a safety inspection. A safety inspection is separate from and in addition to your emissions test, if applicable.
Pennsylvania vehicle safety inspections are designed to inspect the cosmetic and mechanical components of your vehicle.
You are advised to complete your vehicle safety inspection before or along with your emissions test, if necessary.
You can visit any PennDOT-approved safety inspection service station. Contact the Pennsylvania Department of Transportation (PennDOT) for a list of service stations and inspection facilities near you.
The above vehicles aren't the only vehicles exempt from smog and emissions checks. The DOT exempts certain diesel-powered vehicles as well as vehicles that only drive a certain number of miles per year.
