Gov. Jerry Brown has signed a bill authored by state Senator Ellen Corbett that aims to reduce greenhouse gas emissions by improving the fuel efficiency of trucks that move goods in California.
Corbett said Senate Bill 469 will improve the gas mileage of heavy-duty tractor and trailer trucks that travel within the state in compliance with the goals established under Assembly Bill 32, the Global Warming Solutions Act of 2006, to reduce greenhouse gas emissions by 2020.
Specifically, she said, the bill aligns state law to federal law by allowing the use of aerodynamic devices that extend no more than 5 feet beyond the length of a tractor-trailer truck, as well as tarping systems installed on flatbed semitrailers.
According to Corbett, the California Air Resources Board previously identified heavy-duty tractor and trailer aerodynamic improvements as a way to increase gas mileage while also reducing greenhouse gases, as they decrease air flow friction and turbulence around trucks.
However, she said legislation was needed to change the California Vehicle Code to accommodate necessary aerodynamic improvement regulations.
Corbett said she previously authored SB 12 in 2012 to allow the use of aerodynamic devices that extend no more than 3 inches on either side of the vehicle. Gov. Brown signed that bill into law in September 2012.
In a statement, Corbett said, “SB 469 supports transportation technologies that help to reduce greenhouse gas emissions by improving the fuel efficiency of trucks as they travel within and through California.”
She said, “This bill, which earned strong bipartisan support in both the Senate and Assembly, builds upon SB 12, which dealt with the width of trucks.
Corbett said SB 469 similarly ensures that California is in alignment with federal law relating to such aerodynamic devices on trucks as they become more commonplace on California’s freeways and roads.
She said, “I thank Governor Brown for signing SB 469 so that truckers may drive in California knowing that they are in compliance with federal law requirements.”
Corbett said SB 469 was supported by ATDynamics Inc., the California Police Chiefs Association, the California Trucking Association and CALSTART, which is a clean transportation and technology industry group.
