Vehicle Emissions Inspection Program

VEIP - Let's Clear the Air

The Maryland Department of Environment (MDE) and the Maryland Department of Transportation Motor Vehicle Administration (MDOT MVA) jointly administer VEIP. Envirotest of Maryland, Inc. is the private contractor responsible for day-to-day testing operations.  The VEIP testing network consists of 18 centralized inspection stations and 10 self-service kiosks located in 13 counties and Baltimore City. 

Maryland’s VEIP is working. By having your vehic​le 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 air pollution problems. However, we continue to have a problem with ground-level ozone, a major component of smog.
