What vehicles need to be inspected:
All vehicles that are registered in Massachusetts must receive a safety inspection each year. Vehicles listed below must also receive an on-board diagnostic (OBD) emissions test each year:
- Model year 1996 and newer passenger cars, trucks and SUVs, as well as 2008 and newer medium-duty vehicles
- Model year 1997 and newer light-duty diesel vehicles (weighing 8,500 pounds or less)
- Model year 2007 and newer medium-duty diesel vehicles (weighing 8,501 to 14,000 pounds)
- Beginning in April 2009, opacity tests for visible smoke from heavy-duty diesel vehicles (weighing more than 10,000 pounds Gross Vehicle Weight Rating or "GVWR") will resume. This test started in 2002, but was suspended in August 2008 to allow for transition to the new Massachusetts Vehicle Check Program.
- Cars, trucks and SUVs manufactured before model year 1996 no longer receive tailpipe emissions tests but fail their safety inspections if they produce visible smoke.
- Light duty diesel vehicles (weighing less than 8, 500 pounds Gross Vehicle Weight Rating, or "GWVR") that were either manufactured before model year 1997 or are 15 or more model years old
- 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
- All "tracked" vehicles
- All-terrain vehicles (ATVs)
- Articulated loaders/haulers
- Mobile hydraulic platform lifters
- Motor graders
- 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, state 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.
What to bring to your vehicle's inspection:
Bring your vehicle registration and the inspection fee with you.
