ATA Chief Economist Bob Costello said he expects truck tonnage to grow at a slower pace in 2013 than it did in 2012, adding that a stronger economic recovery could boost the industry in 2014 and 2015. Costello, who is a featured speaker at The NATSO Show, predicted a two percent increase in for-hire truck tonnage this year, slowing from the 2.7 percent increase he projected for 2012. Costello said tonnage growth had been slowing throughout 2012. Tonnage in October dropped 3.8 percent and marked the first year-over-year decrease since November 2009. In November, however, tonnage increased 3.7 percent, marking the first gain since July. More
