About Our Program

Maryland’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 the 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 consists of 18 centralized inspection stations located in 13 counties and Baltimore City.

Approximately 3 million motor vehicles are tested every two years.  The following chart summarizes the type of test by vehicle weight and model year. The newest two model years of a vehicle are exempted from the emissions test.

Vehicles that fail the emissions test must be repaired and pass a re-inspection at one of the centralized inspection stations. Motorists are given 120 days to have the vehicle repaired and  return to one of the VEIP stations for a re-inspection. Vehicles that cannot be repaired to achieve the emissions standards may qualify for a two-year waiver if minimum expenditures have been made to repair emissions system components.  The minimum waiver qualifying repair expenditure is $450.00, and the waiver is valid for the assigned two-year inspection cycle.
