Heavy-duty motor vehicles.

Existing law requires the State Air Resources Board, in consultation with the Bureau of Automotive Repair and a specified review committee, 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 requires the state board, in consultation with the State Energy Resources Conservation and Development Commission, to adopt regulations requiring heavy-duty diesel motor vehicles to use emission control equipment and alternative fuels. This bill would delete the references and requirements pertaining to excessive emissions of smoke by heavy-duty diesel vehicles. The bill would instead require the state board, by an unspecified date, to adopt regulations that require owners or operators of heavy duty motor vehicles used for commercial purposes to perform regular inspections of their vehicles for compliance with emission standards of the state board. The bill would require a fleet, as defined, of these vehicles to comply with the state board's emission standards in order for any vehicle of the fleet to be registered by the Department of Motor Vehicles.
