Trucking accounted for 3,200 of the 113,000 jobs added in January, and the U.S. unemployment rate fell to a five-year low of 6.6%, the Labor Department reported Feb. 7.

The job increase was below economists' forecasts of 180,000, and employment gains for December and January were revised upward by a total of 34,000, Bloomberg News reported.

The transportation and warehousing sector, which includes trucking, added 10,000 positions in January, after a similar gain in December that had originally been reported as a small decline.

The trucking industry's 100-jobs gain in December was unrevised.

The unemployment rate is the lowest since October 2008. Analysts had forecast it to hold at 6.7%, Bloomberg reported.
