No Routine Emissions Testing Required In California For Class 7 And 8 Commercial Diesel Trucks
EDIT
As Gov. Jerry Brown and the mayors of Los Angeles and Long Beach promise an emissions-free future, some diesel fumes aren’t going anywhere. That’s because, unlike your car, there’s no routine emissions-testing program for big rigs in California.
And a provision in Senate Bill 1 – the $52 billion road-fixing law Brown signed amid much ballyhoo in the spring – exempts most diesel trucks from emissions-reduction requirements for many years ahead. Instead, the state will continue to rely on random inspections at weigh stations on the side of the road and at border crossings.
Brown has become an international icon for climate-change reform. And the ports in Long Beach and Los Angeles vowed last week to spend billions on cleaner-burning gear and vehicles.
Still, it’s hard to imagine California truly clearing its air with the diesel-emissions pothole in its path. The state’s 1 million diesel trucks account for 2.3 percent of the vehicles on the road – but 56 percent of the smog-forming nitrogen oxides from motor vehicles and 66 percent of the diesel soot.
