Smog & Emission Checks in PennsylvaniaCar 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 a vehicle emission test once a year. So as to alert you 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. 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.
