Dirt bikes and other off-road vehicles sold in California will have to meet tough new anti-smog requirements beginning with 2018 models.
U-T San Diego (http://bit.ly/18FVCNO ) says the state Air Resources Board approved rules Thursday that could reduce fumes seeping from gas tanks and fuel lines by 70 percent -- but also could add hundreds of dollars to the price of new models.
Gases such as cancer-causing benzene, are emitted from off-road vehicles even when they're in the garage. The new regulations would limit them to 1 gram a day instead of the estimated 10 to 15 grams they otherwise would release.
Manufacturers are expected to need design changes to meet the cap -- and that's expected to raise prices.
The regulations will exempt snowmobiles, gas-fueled golf carts and go-karts.
