Information for Motorists: Specialty Vehicles

Specialty vehicles include “7D” vehicles, kit cars, auto homes, and recreational vehicles. Each type of vehicle needs to meet separate requirements to qualify for a passing Massachusetts Vehicle Check sticker.

7D Vehicles

A 7D vehicle is any vehicle registered with the Registry of Motor Vehicles as a school pupil transport vehicle pursuant to M. G. L. Chapter 90 Section 7D. These are usually passenger-type light duty vehicles used to transport school pupils. In addition to their annual Massachusetts Vehicle Check inspections, these vehicles also receive twice-yearly, special 7D inspections. Check the Station Locator to find stations that are authorized to perform 7D inspections.

Kit Cars

A kit car is a unique vehicle or a replica of any vehicle of which fewer than 500 are produced annually. Kit cars need to meet the air pollution control requirements of the U.S. Environmental Protection Agency (EPA) Kit Car Policy in order to qualify for a Massachusetts inspection sticker. These cars must receive an annual safety inspection at an inspection station. Newly registered kit cars need to undergo visual inspections of their emissions control systems at a Motorist Assistance Center. Once they pass their emissions tests, they can be returned to their initial inspection stations to receive their stickers.

Auto Homes

An Auto Home is defined as any motor vehicle originally designed or permanently altered and equipped for human habitation which is not used to transport property other than that property used for human habitation or camping purposes. These vehicles can be identified at inspection stations by the display of Auto Home (“Camper”) plates.

These vehicles undergo a non-commercial safety and emissions inspection regardless of the GVWR of the vehicle, and the inspection fee is fixed at $35. In other words, inspection stations are prohibited from charging an hourly shop rate when inspecting Auto Homes.

  • For Auto Homes with a GVWR under 10,000 lbs, the inspection station must be a Class A, Class B or Class D station.
  • For Auto Homes with a GVWR between 10,000 lbs and 26,000 lbs, the inspection station must be a Class B, Class C, or Class D station. Additionally, the inspector must have completed commercial training.
  • For Auto Homes with a GVWR over 26,000 lbs, the inspection station must be a Class C, Class D or Class E station. Additionally, the inspector must possess a commercial driver’s license (CDL), and have completed commercial training.

Check the Station Locator to find stations that are authorized to perform Auto Home inspections. You may also want to call your inspection station before you go to ensure the facility and their inspectors can accommodate your vehicle type.

Recreational Vehicles

A recreational vehicle is any motor vehicle designed or modified for use over unimproved terrain, if used for recreation or pleasure off a public way. This term also includes all legally registered motor vehicles when used off a public way. Any motor vehicle registered under Chapter 90 will not be subject to registration under Chapter 90B, but must display a current motor vehicle registration.

These vehicles undergo a safety and emissions inspection. Depending on the size of your vehicle, you may need to call your inspection station before you go, to ensure the facility can accommodate your vehicle type.
