The American Trucking Associations’ advanced seasonally adjusted (SA) For-Hire Truck Tonnage Index decreased 1.1% in April 2012 after increasing 0.6% in March. March’s gain was more than the preliminary 0.2% increase ATA reported on April 24.
This latest drop put the SA index at 118.7 (2000=100), down from March’s level of 120. Compared with April 2011, the SA index was up 3.5%, better than March’s 3.1% increase. Year-to-date, compared with the same period in 2011, tonnage was up 3.8%.
The not seasonally adjusted index, which represents the change in tonnage actually hauled by the fleets before any seasonal adjustment, equaled 116.9 in April, which was 5.5% below the previous month.
“While April’s decrease was a little disappointing, the March gain turned out to be stronger than originally thought,” said ATA chief economist Bob Costello. “The ups and downs so far this year are similar to other economic indicators.
“While just one month, the April’s decrease also matches with an economy that is likely to grow slightly slower in the second quarter than in the first quarter,” he said.
Costello said the industry should not expect the rate of growth seen over the past couple of years, when tonnage grew 5.8% in both 2010 and 2011.
“I continue to expect tonnage to moderate from the pace over the last two years,” he said. “Annualized growth in the 3% to 3.9% seems more likely.”
Trucking serves as a barometer of the US economy, representing 67.2% of tonnage carried by all modes of domestic freight transportation, including manufactured and retail goods. Trucks hauled 9 billion tons of freight in 2010. Motor carriers collected $563.4 billion, or 81.2% of total revenue earned by all transport modes.
