Which Vehicles Are Affected
All New Hampshire vehicles require an annual safety inspection. In addition, light-duty (8500 lbs. GVWR and less) gasoline-fueled and diesel passenger vehicles with model years 20-years-old and newer must pass an OBD test. In an OBD inspection, the vehicle is connected to the inspection unit via the standardized OBD port. The inspection unit communicates with the vehicle’s OBD system to determine whether or not the monitors are working properly and if they detect any problems.

Where To Get Your Vehicle Inspected
All public automobile inspection stations in New Hampshire are required to use the NHOST inspection equipment. It is a good idea to call ahead to your station of choice to verify their inspection fees. Click on the link here for a list of inspection stations and their fees (where provided).

Vehicle Owner's Responsibilities
As the vehicle owner, it is your responsibility to ensure the vehicle complies with inspection requirements. Just as you are required to correct any safety issues with the vehicle before it will pass the safety inspection, you are also required to correct any OBD system problems before your vehicle can pass the inspection and receive an inspection sticker.
The OBD system is installed on the vehicle to ensure that it runs smoothly, lasts longer and releases as few pollutants as possible. Repairing problems sooner rather than later could save you money in repairs and at the pumps.
