Here's what happens during an emission inspection in Lorton, VA:
Emission inspection cost and exemptions - A vehicle emissions inspection may cost up to $28. Vehicles exempt from the inspection include motorcycles, registered antique vehicles, fire and rescue equipment, and vehicles powered exclusively by clean fuels.
Emission inspection waivers - When a vehicle fails the tailpipe emissions inspection standards or an On-Board Diagnostic (OBDII) inspection, a waiver may be obtained if a specified amount has been spent on emissions-related repairs for that vehicle. Repair work must be performed at a DEQ-certified emissions repair facility such as Wiygul Automotive Clinic and performed, or supervised and approved, by a DEQ-certified emissions repair technician, no more than 60 days before the initial inspection failure. A waiver is valid for two years.
Dynamometer - Exhaust emissions are tested while a vehicle operates on a treadmill-like device, called a dynamometer, at 15 mph and 25 mph only. No high-speed testing is performed.
Two speed idle test - Some vehicle exhaust emissions are tested while operating at idle and at an engine speed of 2,500 rpm.
On-board diagnostic II (OBD II) inspection - Most 1996 and newer model year vehicles will be subject to a computerized analyzer check that will look for fault codes that may be present in the vehicle's on-board computer. This inspection may be performed instead of, or in some cases in addition to, the dynamometer or two speed idle test on eligible vehicles.
