The American Trucking Associations' advance seasonally adjusted (SA) For-Hire Truck Tonnage Index increased 2.7 percent in November, following a 0.2 percent contraction in October. The latest gain boosted the SA index from 103.6 (2000=100) in October to 106.4, its highest level in a year. The not seasonally adjusted index, which represents the change in tonnage actually hauled by the fleets before any seasonal adjustment, equaled 100.8 in November, down 8.0 percent from October.

Compared with November 2008, SA tonnage fell 3.5 percent, which was the best year-over-year showing in twelve months. In October, the index was down 5.2 percent from a year earlier.

ATA Chief Economist Bob Costello said that tonnage is moving in the right direction. 'Slowly, but surely, truck freight has started the recovery process and November's solid increase is a very positive sign,' Costello noted. He said that November's tonnage levels were pushed higher by improved economic activity, as well as by an inventory correction that is near completion. 'Truck freight had been hurt by both slow economic output and bloated inventories; however, we now have evidence that the inventories are in much better shape, which will not be such a drag on truck freight volumes.' Costello continued to be cautious about the future though. 'While the economy and trucking is improving, the industry should not get overly excited about the sizeable increase in November. I continue to believe that both the economy and truck tonnage will exhibit starts and stops in the months ahead, but the general trend should be for moderate growth.'

Note on the impact of trucking company failures on the index: Each month, ATA asks its membership the amount of tonnage each carrier hauled, including all types of freight.' The indexes are calculated based on those responses.'The sample includes an array of trucking companies, ranging from small fleets to multi-billion dollar carriers. When a company in the sample fails, we include its final month of operation and zero it out for the following month, with the assumption that the remaining carriers pick up that freight.'As a result, it is close to a net wash and does not end up in a false increase.'Nevertheless, some carriers are picking up freight from failures, and it may have boosted the index. Due to our correction mentioned above, however, it should be limited.

Trucking serves as a barometer of the U.S. economy, representing nearly 69 percent of tonnage carried by all modes of domestic freight transportation, including manufactured and retail goods. Trucks hauled 10.2 billion tons of freight in 2008. Motor carriers collected $660.3 billion, or 83.1 percent of total revenue earned by all transport modes.

ATA calculates the tonnage index based on surveys from its membership and has been doing so since the 1970s. This is a preliminary figure and subject to change in the final report issued around the 10th day of the month. The report includes month-to-month and year-over-year results, relevant economic comparisons, and key financial indicators.
