Washington -- The Environmental Protection Agency announced fuel efficiency standards for U.S. commercial trucks for the first time, similar to rules for lighter vehicles.
The rules cover fuel consumption and greenhouse gas emissions and are shaped to cover a variety of larger vehicles, such as vans, buses, tractor trailers, fire trucks and cement mixers, The New York Times reported Monday.
Various classes of vehicles under the proposal have different standards. Tractor trailers and buses, if the rules meet final approval, would have to reduce gas consumption by 20 percent by 2018. Trucks under the category of "work trucks," like cement trucks that drive far fewer miles per year, would have to reduce gas consumption by 10 percent by 2018.
