Less trucks , more drivers ?

From Werner's latest quarterly report . "Highlight of Business Operations:
Operating revenues increased 10.0% for the three months ended September 30, 2011, compared to the same period of the prior year. Trucking revenues, excluding fuel surcharges, increased 0.7% due primarily to a 2.9% increase in revenue per total mile, offset by a 2.0% decrease in the average monthly miles per tractor and a 0.1% decrease in average tractors in service." http://www.gurufocus.com/news/151561/werner-enterprises-inc-reports-operating-results-10q
Less tractors in service ? Where are all those new drivers going through orientation going ?
Number of tractors in past years is no longer available at safersys.org like it was before CSA 2010
Are some fleets increasing in size ? Yes , because bottom feeders offer cutthroat rates to manufacturers that had private fleets . Schneider and JB put well paid , safe drivers out of work with their cheap rates . WalMart also told vendors they could no longer ship their products . Schneider would pick them up .
