Heavy-duty vehicles: smoke emissions.

Existing law requires the State Air Resources Board (state board) to adopt regulations requiring owners or operators of heavy-duty diesel motor vehicles to perform regular inspections of their vehicles for excessive emissions of smoke. Existing law additionally requires the state board to adopt regulations that require that heavy-duty diesel motor vehicles subject to the above-described requirements utilize emission control equipment and alternative fuels. This bill would make a technical, nonsubstantive revision to the requirement that the state board adopt regulations that require that heavy-duty diesel motor vehicles subject to the above-described requirements utilize emission control equipment and alternative fuels.
