ARLINGTON, Va. — US for-hire truck tonnage dropped 1.5% in June, but was 2.1% stronger year-over-year, according to the latest data from the American Trucking Associations (ATA).

The decrease followed a revised 2.9% gain in May.

Year-to-date, tonnage is up 3.7% compared to the same period in 2015, the ATA reports.

“The seesaw pattern continued again in June with tonnage falling after a good rise in May,” said ATA chief economist Bob Costello. “On a month-to-month basis, tonnage has been down in three of the last four months, totaling 4.7% since February. Looking ahead, I expect the freight environment will remain choppy. The good news for trucking is we are the most diverse mode of all freight transportation sectors between industrial and consumer freight. We are currently benefiting from the consumer side while being hurt on the industrial side. And of course we still have the inventory glut that is weighing down tonnage.”
