the only regulation the trucking industry needs is safety . govt needs to stay out of fuel mileage . marketplace will improve mileage through competition and research .better mileage equalls more sales of trucks and better bottom line for truckers . these tree hugging goons in the white house make me sick .
The new regulations are based on ton-miles. EPA is using 38,000 pounds for Class 8. The trucking industry might lobby to have increased payload weight and length (more of the triple-trailer trucks and double 48s) as part of the solution.
