A fixed VIC is a stationary facility a vehicle drives to. An authorized mobile DriveON facility brings licensed technicians and approved equipment to the vehicle's yard instead. Valid testing requires an authorized facility and a licensed technician — not every person with portable equipment can issue a DriveON result.
Both options use the same official DriveON procedures and report results the same way. The inspection standard does not change because the truck was tested at a yard instead of a fixed building.
Qualifying heavy-duty diesel vehicles receive an opacity test. Eligible vehicles also receive an OBD system check or OBD data collection based on model year and GVWR under the current DriveON directive. OBD should not be described as a universal replacement for the opacity test.
For an owner-operator already near a VIC on a scheduled route stop, a fixed-location test may simply be more convenient. Fixed VICs remain a valid and sometimes preferable option when travel and waiting time are already absorbed into the day's plan.
For a long-haul fleet based off the 401 with several tractors on staggered schedules, sending one truck at a time to a fixed VIC means repeated dead-mileage trips and driver time away from revenue runs. A mobile visit can allow several prepared units to be inspected at the yard when the site is safe, units are available, and the technician can perform the procedure correctly.
Multi-unit fleets benefit most when due trucks are staged together for one visit rather than scattered across separate fixed-VIC trips. Coordinate plate renewals and ownership transfers so eligible units can be inspected in one window where practical.
Neither option changes the underlying compliance requirement or the opacity and OBD rules that apply to the vehicle. Related guides: Highway 401 corridor testing and long-haul tractor emissions. Arrange mobile testing through Piotr Service.
