Want to idle that diesel engine in your 2008 or newer medium-duty truck in California for more than five minutes? You'll need a sticker for that.
Way back in 2008, the California Air Resources Board (CARB) decided to make it illegal to idle diesel-engined trucks with a gross vehicle weight rating (GVWR) over 14,000 pounds for more than five minutes. That GVWR is above that of most heavy-duty pickups like the Dodge Ram 3500, Ford F-350 and GMC Sierra 3500, but does cover most chassis-cab trucks.

CARB's regulation says that manufacturers of diesel engines have to either incorporate an anti-idling system or to certify that the engine emits 30 grams or fewer of nitrogen oxide per hour in order to get a sticker. If the oil-burning engine meets that limit, it can, at least in theory, idle forever.

For 2011, the Ram 4500/5500 and Ford F-450/F-550 chassis-cab trucks meet CARB's certified clean idle requirements, meaning that they get one them flashy stickers (pictured). Being able to idle indefinitely isn't really sticker-worthy, right?

      Should be illegal in all vehicles, not just trucks. Can't count how often I see people idling in their car to yap on the phone or whatever - even when it's not even close enough to need A/C. Even better - just add auto start/stop with a slightly bigger battery.

        I agree, but i'd go one step further. I would like to see every new car equipped with some sort of mild hybrid/start stop system that has all engine accessories(power steering,A/C, water pump,...) be electric driven and battery powered when the vehicle is stopped. ...I also find it amusing that Michigan is the only state (that i know of) that has made it illegal to have an unattended vehicle idling (put in place to curb auto theft). Kinda funny that the home of the Motor City is one of the first to think of this...

        I was thinking same thing; it is something technology should be able to address.....I think breathalyzer is weird technology, i.e. if you have a DUI, you have to pass test before driving, but auto start stop being mandatory is a no-brainer and it would save billions of gallons of fuel and profits for trucking cos....and gas for consumers..and long term health care costs for residents in badly designed communities who have to live with toxic exhaust and asthma and respiratory diseases etc. and pedestrians. it says something when every US auto mfg. thinks gas taxes need to go up at least a dollar in order to incentivize new technology and make it worth it to really have real breakthroughs.....right now gas is way too artificially cheap for most to give a sh*( except complain about 'high' gas prices which are half of world average.

          I'm with you 99% of the way...the "true" fuel price debate is where I usually make enemies on both sides. Our fuel prices are kept lower via subsidies, but the "average" that everyone talks about for the rest of the world is greatly skewed in comparison. Few people know or realize that most of Europe over taxes their fuel purposely to encourage mass transit. Most reports that I have read state that fuel should be around $4.00 - 4.50 world wide(@ 100ish a barrel) if the taxes and subsidies were removed. This is why its so important to get away from fossil fuels: too much manipulation, money lost, and money wasted on price adjustment endeavors that do little but cause economic upheaval and instability. Personally, I have always found it amusing that we both subsidize and tax our fuel at the same time..doesn't really make sense...

      Worry not, Sooner or later they will figure out it is costing them money to leave them running. It's laughable really.

        @GeorgeS
        Not it is not laughable. Try sleeping in a hot hot house. Would you be happy? I think not. So do you think sleeping a truck would be comfortable with no air conditioning? It is not! It can get 140 degrees in the sleeper truck if the ac is not running and how do you run ac? You have to idle the truck.

      I realized one big reason they idle the other day - to keep the cabin cool with a/c. It doesn't make it less polluting, but it's not on for nothing. Truck drivers need comfort and rest to do their job safely. A/C provides comfort.

      Often walk by a liquor store down the street. Half the vehicles are idling while the driver runs inside. Almost always with moron diesel drivers. Gotta show off their manly stink-pot I guess.

        in these times, I am surprised somebody doesn't drive off with their vehicles, like a junkie or crackhead.....it is why nobody diesels in cold climates; it is too easy to spot a car to jack.....you could just take their keys and then it wouldn't be idling at all.....and they would get in better shape walking back to house to explain to missus why their ride is sitting in liquor store parking lot.

      So, if I emit less than the other guy, I have the right to emit indefinitely? What a stupid law. Idling in any car should be forbidden. RE: the anti-Prius rant... very funny... Prii gasoline engines turn on to recharge the batteries when you're sitting in traffic if the battery pack gets too low and you have the AC howling on full in summer weather.

      Typical of a state where many voters are Prius owners. Smug bastards...

      Many of you already know this but just in case... Los Angeles has the worst smog problem in the world for mainly two reasons . The population of Los Angeles and Orange County is over 13 million. That's slightly more than one third of the population of the entire state of California, the most populous state in the USA. The other reason smog is so bad there is something called the inversion layer. I'm no meteorologist but apparently the inversion layer traps the smog very efficiently. Even before there were millions of people living there the native Americans called it "The Valley of Smoke" because the inversion layer trapped the dust. This is why CARB has the strictest emission regulations in the world.

        Not to take anything away from the spot-on points in your post but 'm pretty sure that L.A. doesn't even make the top ten according to the last Climate Change Summit...Beijing and New Delhi are tied for first in the world.... That being said L.A. is the worst in the U.S. by far. If there is any one city in the U.S. that needs a clean mass-transit solution, it is L.A.

      Why dont we prevent trucks from coming in? .. Just use trains . Or at least up the fuel tax in trucks $2,00 a gal?
        • 3 Years Ago
        @Floorman
        Yeah we can raise the fuel tax for trucks but guess what will happen? All that lovely stuff you buy that trucks bring in will go up up up ! And How do you suggest the products get from the trains that you suggested? Do you want trains and tracks all over the place? And did you know trains cause pollution and idle as well?

      Idling any car over 5 min is stupid and should be forbidden. We breate in enough poison already, we don't need even more because some brainless wacko thinks it's cool to waste away fuel for nothing.

        Where i grew up, they had banned drive-thrus. What a great way to reduce unnecessary emissions.

Prii gasoline engines turn on to recharge the batteries when you're sitting in traffic if the battery pack gets too low and you have the AC howling on full in summer weather. Of course, they won't do it unless you leave the fob in the car and the AC on when you run into the store.
