The Environmental Protection Agency and California Air Resources Board have agreed to begin a “thorough review” of their policies regarding the operation of selective catalytic reduction-equipped heavy-duty diesel engines when diesel engine fluid tanks run dry.

The National Highway Traffic Safety Administration and the U.S. Environmental Protection Agency on Aug. 13 sent their proposed standards for heavy- and medium-duty trucks to the White House for review by the Office of Management and Budget.

The California Air Resources Board staff is recommending an extension of the compliance deadlines for the state’s emission-reduction rule for 2003 transport refrigeration units.

Bose Corp. said that its sophisticated new heavy-duty truck seat is now available to small fleets and owner-operators at five installation sites.

If your fleet uses electronic driver logs and plans to buy trucks after June 4, 2012, be sure to tell your company’s chief technology officer ahead of time.

Norfolk Southern Corp. said it completed a reconfigured rail junction in Northern Virginia, part of its “Crescent Corridor” aimed at boosting East Coast freight rail speeds.

Many fleets are shifting to late-model used trucks to meet their need for additional vehicles, according to registration data provided by R.L. Polk & Co.

U.S. registrations of new Class 8 trucks increased 7.8% in the second quarter compared with the same 2009 period, but failed to keep up with equipment retirements, as the total of heavy-duty trucks registered in June declined slightly from last year, according to R.L. Polk & Co.

The U.S. Department of Transportation said it is adding new tests for transportation workers to detect the designer drug “ecstasy,” while also lowering the positive threshold amounts of amphetamines and cocaine and adding a new marker to identify heroin use.
