Truck tonnage in April declined 11.3 percent compared with 2019 levels, the steepest year-over-year decline since 2009, American Trucking Associations reported. On a sequential basis, April was down 12.2 percent from March. April’s monthly decline was the largest in 26 years when there was a labor strike in April 1994, according to A-T-A Chief Economist Bob Costello. He also said the drop wasn’t surprising considering that April factory output and retail sales plummeted.
