Vehicle Emissions Inspection Program

VEIP - Let's Clear the AirMaryland’s Vehicle Emissions Inspection Program (VEIP) is an important component of the State’s plan to improve air quality. By requiring inspection of vehicle emission systems every two years and repair of vehicles that fail to meet emissions standards, VEIP significantly reduces vehicle emissions that contribute to Maryland’s air quality problem of ground-level ozone. 

The Maryland Department of Environment (MDE) and the Motor Vehicle Administration (MVA) jointly administer VEIP.  Environmental Systems Products of Maryland, Inc. (ESP) is the private contractor responsible for day-to-day testing operations.  The VEIP testing network constists of 18 centralized inpsection stations located in 13 counties and Baltimore City.

Maryland’s VEIP is working. By having your vehicle tested, you are playing an important part in Maryland’s successful and ongoing efforts to create a healthier Maryland. Along with cleaner fuels and vehicles, VEIP has significantly reduced Maryland’s carbon monoxide pollution problems. However, we continue to have a problem with ground level ozone, a major component of smog.


All MVA and VEIP Locations are closed on the following state holidays and in accordance with the state budget reduction plan:

Columbus Day

Saturday, October 10, 2015 and Monday, October 12, 2015
