How to Get Smog Technician Certified in Pennsylvania

The state of Pennsylvania requires that any vehicle that is required to participate on the Emissions I/M program go through an emissions testing when the associated safety inspection is performed. For mechanics seeking an automotive technician job, an excellent way to build a resume of valuable skills is to seek out a smog inspector’s license.

Pennsylvania smog inspector qualifications

In order to perform smog checks for any commercial or non-commercial vehicle in the state of Pennsylvania, an automotive service technician needs to have the following qualifications:

  • The mechanic must be at least 18 years of age.

  • The mechanic must possess a valid Pennsylvania driver’s license. This license does not have to be in the class of the vehicle being inspected.

  • The mechanic must have completed a state-approved emissions training course, and passed the required written exam with a score of at least 80%.

  • The mechanic must have completed a practical demonstration, either under the supervision of a certified automotive educator, or via computer-based testing offered by the training course.

In order to maintain an emissions certification, a mechanic must attend a refresher course and pass a written exam every two years. Additionally, a mechanic with an emissions inspection license may only inspect vehicles in a licensed inspection station.

Smog technician salary

Becoming a licensed smog technician can help a mechanic build experience in their career and have a well-rounded resume. One of the things that many mechanics wants to know is how a smog technician certification may change or enhance their auto mechanic salary. According to Salary Expert, smog technicians receive an average annual salary of $23,708 in Pennsylvania.

Smog check procedures in Pennsylvania

  • An ASM test on all vehicles newer than 1981. This procedure is approved by the EPA in the I/M program.

  • An OBD I/M check from vehicles newer than 1966.

  • A visual examination of the gas cap, to ensure it is properly installed and not allowing any vapor to escape.
