Photograph of a Massachusetts vehicle inspection station. All vehicles that are registered in Massachusetts must receive a safety inspection each year. Vehicles listed below must also receive the following types of emissions tests each year:

On-Board Diagnostic (OBD) Test:

  • Model year 2001 and newer passenger cars, trucks and SUVs

  • Model year 2001 and newer light-duty diesel vehicles (with a Gross Vehicle Weight Rating or "GVWR" of 8,500 pounds or less)

  • Model year 2007 and newer medium-duty diesel vehicles (with a GVWR of 8,501 to 14,000 pounds)

Opacity Test:

  • Medium- and heavy-duty diesel vehicles (with a GVWR of 10,000 pounds or greater) not equipped with OBD systems

The following types of motor vehicles are exempt from the emissions inspection:

  • Cars, trucks and SUVs manufactured before model year 2001 no longer receive tailpipe emissions tests but fail their safety inspections if they produce visible smoke
  • Light duty diesel vehicles (with a GVWR of less than 8,500 pounds) that were manufactured before model year 2001
  • Medium duty diesel vehicles (up to 10,000 pounds GVWR) that were either manufactured before model year 2007 or are 15 or more model years old
  • Medium duty non-diesel vehicles either manufactured before model year 2008 or 15 or more model years old
  • New vehicles delivered to Massachusetts owners
  • Motorcycles and mopeds
  • Tactical military vehicles
  • Vehicle operated exclusively by electric power

Vehicles that are not designed to be operated on Massachusetts roads do not receive emissions tests. These include:

  • All "tracked" vehicles
  • All-terrain vehicles (ATVs)
  • Articulated loaders/haulers
  • Backhoes
  • Bulldozers
  • Cranes
  • Excavators
  • Loaders
  • Mobile hydraulic platform lifters
  • Motor graders
  • Pavers
  • Self-contained street-sweepers, maximum capable-speed of 20 mph, such as a three-wheeled vehicle (does not include on-road vehicles with street sweeping equipment installed as cargo; such vehicles are subject to emissions inspections)
  • Skid-steer loaders
  • Tractors and off-road equipment used for farming (does not include pickup trucks, stake trucks, tractor trailers and other vehicles designed for road use with farm registration plates; such vehicles are subject to emissions inspections)

When do vehicles need to be inspected?

Your vehicle must undergo both an emissions test and a safety inspection every year before its current inspection sticker expires (at the end of the month printed on the sticker). To avoid end-of-the-month lines, have your vehicle tested during the first half of the month when it is due for an inspection. If you purchase a vehicle (new or used), it must be inspected within seven calendar days of its registration to continue operating on Massachusetts roadways.
