|WELCOME to the New Hampshire OBD and Safety Inspection
In 2007, we successfully reached the final milestone in the NHOST
Program: OBD testing is now Pass/Fail for all model year 1996 and
newer automobiles and light-duty trucks. The transition has gone
great with stations and motorists adapting smoothly to the changes.
Although the program is now fully operational, we will continue
to communicate with stations via "Blasts" of important information
sent directly to the NHOST Units.
We appreciate all of the efforts made by inspection stations
and mechanics, especially your patience throughout the program implementation
There is also general program information available to print
from this website or the NHOST unit. Stations may also want to provide
the following NHOST website to motorists to guide them toward more
- Over 2000 stations participating.
- Over 8000 New Hampshire
mechanics have completed training and passed the computer-based
- Over 2.5 million inspections on the database.
- More than 2 million OBD inspections performed.
The New Hampshire Department of Safety -
Division of Motor Vehicles (NH DMV) and
NHOST Services, Inc. (NHOST) are working closely together to ensure
that the program continues to operate smoothly.
