(a)
The department shall incorporate a visible smoke test into the motor vehicle inspection and maintenance program by January 1, 2008. Any visible smoke from the tailpipe or crankcase of a motor vehicle during an inspection constitutes a failure. Steam from condensation by itself shall not lead to an inspection failure.(b)
If an owner of a motor vehicle disputes the failure of a visible smoke test, the owner may seek resolution of the dispute from the state-designated referee.(c)
The department, in consultation with the state board and interested parties, shall adopt regulations to implement this section. No new equipment shall be required to implement the visible smoke test.(d)
If the implementation of the visible smoke test required by subdivision (a) requires modification of the Emission Inspection System software or Vehicle Information Database, that modification shall be performed as part of the ordinary, periodic upgrade to these systems.
