There’s been the ongoing political fight involving the trucking aspects of the 
North American Free Trade Agreement since the Clinton administration. Several months ago the Obama Administration implemented a pilot program whereby Mexican trucking companies could begin operations in the United States.
Apparently about 20 trucking companies from south of the border are awaiting approval from the U.S. to begin operations here. Produce shippers are salavating at the prospects of access to more transportation and cheaper rates to move fruits and vegetables to markets across the U.S. and Canada. Meanwhile, many in the trucking industry are fighting made over the prospects of unsafe Mexican trucks undercutting freight rates.
