U.S. heavy-duty truck sales fell 24.3% in March to 13,101 vehicles, the seventh straight year-over-year decline, WardsAuto.com reported. Truck makers and dealers blamed the slump on ongoing economic uncertainty and regulatory concerns.

Although sales improved 4.4% from February’s tally of 12,546, the first-quarter total of 38,805 was down 17.2% from the first quarter of 2012, Ward’s reported.

The drop-off in March was the steepest year-over-year decline since October 2009. How is it for this month [May] is there a growth?
