In a Federal Register posting Tuesday, the National Highway Traffic Safety Administration and U.S Environmental Protection Agency said they will be accepting comments on the proposed standard through Jan. 31.
The proposal would cut emissions from large trucks by 7% to 20% by 2017 depending on the truck, its size, and the way it is used.
The regulation will be made final by July 2011 and go into effect for the 2014 and 2017 model years.
