CA Tightens Smog Rules for Off-Road Vehicles

Jul 26, 2013 2:30 PM

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 ( says the state Air Resources Board approved rules yesterday 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.
