Inspection Industry: Inspection Station Licensing

Station Licensing

All inspection stations are required to be licensed by the Registry of Motor Vehicles (RMV) to conduct vehicle inspections. The Massachusetts Vehicle Check program has reached a full complement of public light-duty and public mobile inspection stations. Licenses are still available for fleet, fleet mobile and heavy duty public inspection stations (note: these stations include inspections performed on trailers), as we anticipate an increased need for this class of station. A minimum 45 foot long by 14 foot wide inspection bay is required (except for fleet mobile inspectors). Also, a commercially trained, CDL-licensed inspector must be available at all times to perform inspections.

An applicant for a class M motorcycle inspection station license must be a Motorcycle Dealer licensed pursuant to M.G.L. c. 140, § 58 or a motorcycle repairman who possesses a license required by law to carry on a repair business and who has received factory training or equivalent training approved by the Registrar.

For more information about inspections and licensing requirements, please see the inspection station rules and regulations posted here or call the station support hotline at 877-834-4677.

If you would like to be considered for a fleet, mobile, or heavy duty public inspection station,
please e-mail Please include the following information:

  • Station Name (if applicable)
  • Contact Person
  • Address
  • Telephone
  • Email
  • Class of station you are interested in applying for (Class C, D, E, or F)

Alternately, you may send you request via U.S. mail to: Terence Hayes, Massachusetts Department of Transportation, RMV Division, P.O. Box 55892, Boston, MA 02205-5892.

Please note: The RMV does not anticipate utilizing stations on the “waiting list” for a public light-duty inspection station except under extenuating circumstances, such as areas of the Commonwealth that are deemed to be underserved. If you have previously placed your name on the waiting list for a Class A or Class B station license, we will contact you if a license becomes available.
