Welcome to the Massachusetts Vehicle Check website for current and prospective inspection station owners and managers.

This page contains links to information about the licensing process, testing equipment, inspection regulations and much more. We hope you find it helpful as you become a part of or continue your participation in the program.


Licensing Policies

All inspection stations are required to be licensed by the Registry of Motor Vehicles (RMV) to conduct vehicle inspections. RMV station licensing policies include guidance on which station license Classes are open and which license Classes are closed, the requirements to maintain an active station license, inspector training and licensing requirements, and more.

Please review these policies if you are:

  • Considering an application to own and operate a new inspection station
  • Transferring the ownership of an existing station to a new owner, or
  • Relocating an existing station to a new physical location

These policies are a supplement to the inspection station licensing requirements found in MGL c.90 s.7A and 540 CMR 4.08, included in the Station and Inspector Resources section for your convenience.


Station Licensing Classes & Availability

Station Licensing Classes
Inspection station licenses are divided into classes, based upon the type(s) of vehicle chassis and the Gross Vehicle Weight Rating (GVWR) of the vehicles that will be inspected. GVWR is defined as "the maximum loaded weight for which the vehicle is designed, as specified by the vehicle manufacturer”. The following table provides a summary glance of the vehicle types inspected by each station licensing class.
