Gov. Brown Signs Truck Fuel Efficiency Bill

July 17, 2014 17:30 pm · 14 comments

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.

“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.”

I’m sure that’s among their primary concerns.

Reptards are offended by this effort to improve
and reduce human impact on an already strained
environment . And if they are, screw ’em!
Someone has to think of the future.
Oh ya, closed early, and we are outta here!

Does this include the trucks from Mexico too or are they getting another ‘free ride’ from the taxpayers of this state?

It only applies to law abiding, tax paying Americans!! All others are exempt!!!!

My only question is: Why did this take so long?

I’m actually surprised that the Libtards (see #2 above) didn’t require these devices, rather it appears that this is optional, i.e., a free market solution to fuel efficiency improvement. And this is in Demifornia? Maybe there is hope.

Leave it to a Democrat to waste time and money.

Will these devices also prevent the sudden air suction affecting other vehicles when a truck passes? If so, then it’s an especially good deal,

Why do they call them goods? Sometimes those products aren’t good at all. I think there should be a companion bill to this one, declaring goods must never be transported with bads.

We’ve been seeing these improvements on bug rigs for a while, cab fairings, fences under trailers, and fairings on the rear of trailers to reduce suction. All are steps in the right direction. Now they need to streamline those huge, flat grills.

These politicians expect pats on the back, on the rare occasions they simply DO THEIR JOB.

Since these devices will reduce drag by allowing the truck to move through the air easier, they will reduce turbulence. The flow field behind a blunt body (like the squared off back end of a truck or trailer) creates a lot of turbulence and “suction” so these devices should result in less disturbance as they go by. That is why the aft end of an airplane fuselage is tapered, as is the trailing edge of an aircraft wing.

@Antler #7
Theoretically they would, but it’s hard to make basically a brick(aka tractor/trailer) aerodynamic. New trucks are better aerodynamically than the ones of years past. What ever it costs to retrofit older trucks or build them even more aerodynamic will only be passed on to the end consumer (me & you). You won’t be able to draft them as well neither…(NASCAR joke). I know ClayDen…friends don’t let friends watch NASCAR.

Hope no…; “Someone has to think of the future” > 17 trillion in debt, > 100 trillion in unfunded liabilities and it just keeps growing and growing — who’s thinking about the future? All the while hordes of illegals flooding the already over-taxed system.

Maybe all or the uber-rich greenies like Bill Gates, George Soros, etc can pay for these TrailerTail® systems for the independent owner/operators. Maybe the California Police Chiefs Association, the California Trucking Association and CALSTART can pitch some of their retirement savings. I’m sure ATDynamics Inc. would love the (extra) support for their TrailerTail® system. I wonder if the Mexican truckers will be required to install this on their trucks? Last time I saw one of these Mexican rigs I was billowing out smoke and had no muffler. It looked like it was from the 60’s and had drum brakes. Perfect for stuffing the back of a car, destroying the Obama sticker.
