New Jersey smog inspector qualifications

In order to become a smog inspector in the state of New Jersey, a mechanic must complete the same training course from a state-approved training provider required to receive the standard vehicle safety inspection license.

Each particular training provider dictates their own fees. The inspector licensing fee is $50. Each licensed training course much cover the following training objectives:

  • Causes and effects of air pollution
  • Regulations and procedures of emissions inspections
  • Function, configuration, and inspection of emissions system
  • Operation and maintenance of emissions components

An inspector’s license is valid for two years, and must be renewed with the Motor Vehicle Commission when it expires. Applications for new or renewing licenses can be found online.

Smog repair technician certificate

There are three steps to becoming certified in New Jersey to repair emissions systems. These are:

  • The technician must register for an ERT (Emissions Repair Technician) identification number.

  • The technician must meet all the requirements laid out in the New Jersey Emissions Repair Technician Initial Certifications Requirements. There are two routes towards meeting these requirements. The first is a testing option for those with ASE certifications and experience; the second is an education option for those who lack other certifications and experience.

  • The technician must provide any ASE certification status to the New Jersey DEP if applicable.

After these three steps have been completed, and all testing and/or education is passed, the technician will receive their smog repair technician certificate.

Chevrolet Equinox - Brake Pads Replacement (Rear) - Niles, Illinois
Rigo was great! He got there early, finished the job early, left everything clean. He changed my rear pads and rotors. The original quoted time was 90 minutes, he was done in about 60. He knows what he is doing and I am recommending him to all my friends and coworkers.
