Any PennDOT Authorized Emissions Inspection Station can test your vehicle. To save time it would be a good idea to combine both safety inspection and emission testing on the same day.

It must then be retested, which if undertaken within 30 days of the first test, will be free of charge. If the vehicle fails the test again, you could receive a one year waiver if proof of spending over $150 in repairs is submitted. This can only be done by a PennDOT Authorized Emissions Inspection Station.
