Understanding Mandatory Testing For Car Emissions in Centreville, VA

Here are the facts about mandatory Virginia state testing of car emissions for Centreville, VA, auto owners.

The Virginia Department of Environmental Quality (DEQ) inspection program, called Air Check Virginia, tests car emissions in Centreville, VA and also applies to vehicles registered to Northern Virginia residents, belonging to regular commuters, or operating on federal properties located in the following jurisdictions:

Arlington, Fairfax, Loudoun, Prince William, and Stafford counties 
and the cities of Alexandria, Fairfax, Falls Church, Manassas, and Manassas Park

The inspection date for your car emissions test near Centreville, VA, is determined by the date your vehicle registration is due. The Virginia Department of Motor Vehicles (DMV) “provides notification six to eight weeks before” your car emission inspection deadline. Test results are electronically sent to the DMV to update your vehicle records so you can renew your car registration.

The type of test used to measure car emissions near Centreville, VA, depend on the type and age of your vehicle. The Two-Speed Idle Test measures hydrocarbons and carbon monoxide at 2,500 RPM and at curb idle for car model years 1980 and older that weigh 8,501 lbs. to 10,000 lbs. In the Acceleration Simulation Mode (ACM) Test a dynamometer clocks the vehicle at 15 MPH and 25 MPH to calculate levels of nitric oxide, hydrocarbons, and carbon monoxide. The ACM test is generally for vehicles manufactured during and after model year 1981 weighing less than 8,500 lbs. Modern gas-powered vehicles (model years 1996 and newer, along with light-duty diesel vehicles after and including model year 1997) under 8,500 lbs have On-Board Diagnostic, Generation II (OBDII) Systems. The diagnostic equipment connects to your vehicle’s computerized OBDII engine management system to generate codes that trained technicians use to diagnose and repair emissions control system problems.
