Smog Check in PennsylvaniaPage OverviewCar 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.
The state requires many vehicles to undergo smog checks once a year (see "Basic Smog Check Exemptions" and "Pennsylvania Incentives for Eco-Friendly Driving" below to find out if your vehicle is exempt from testing).
To let you know when your time is up, the state will stamp on your vehicle's renewal notice the words "Emissions Inspection Required/Diesel Vehicles Exempt."
You can have your vehicle tested at any PennDOT-approved service station, dealership, or neighborhood garage. (Refer to our Local Smog Check Stations widget below to find a station near you.) To stem the inconvenience, the state recommends coordinating the test with your vehicle's annual safety inspection to save time.
The cost for an emissions test varies with each station, so you're encouraged to call ahead to find out the price.
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.
Some vehicles fall under a sort of "basic exemptions" category. Those vehicles include:
- Registered antiques, street rods, and collectibles.
- Vehicles registered in the following counties: Adams, Armstrong, Bedford, Bradford, Butler, Cameron, Carbon, Clarion, Clearfield, Clinton, Columbia, Crawford, Elk, Fayette, Forest, Franklin, Fulton, Greene, Huntingdon, Indiana, Jefferson, Juniata, Lawrence, McKean, Mifflin, Monroe, Montour, Northumberland, Perry, Pike, Potter, Schuylkill, Snyder, Somerset, Sullivan, Susquehanna, Tioga, Union, Venango, Warren, Wayne, and Wyoming.
Other vehicles are exempt due to their eco-friendly status. Read on.
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.
