Hey, no problem — go ahead and limit the speed. That’s what you would expect from a socialist country. The truckers will simply move south — to a free country.

Large-scale manufacturing of 550-horsepower, 13-liter diesel truck engines that can run for a million miles is such a complicated endeavor that, since 1990, EPA has given engine makers some short-term wiggle room on hitting emissions targets through its averaging, banking and trading program.

Florida’s Environmental Regulation Commission has approved a rule barring heavy-duty trucks from idling longer than five minutes.

The fuel price express took a holiday last week, as the average price of diesel dipped 4.4 cents a gallon to $4.648, and the price of gasoline declined for the first time in three months, according to the Department of Energy.

UPS Inc. lowered guidance on its second-quarter earnings by about 15%, less than one week after FedEx Corp. posted its first quarterly loss since 1997, demonstrating that even the two largest corporations in North American freight transportation, with the most far-reaching global footprints, are ultimately not immune to the continuing struggles of the all-but-stagnant U.S economy.
