Allowing Mexican long-haul trucks full access inside the U.S. is a component of NAFTA. Safety and security issues have proven to be a huge stumbling block in achieving this objective of the agreement. Under the Bush administration, a cross-border trucking program was established, giving a limited number of Mexican trucks full access beyond the commercial zone restrictions. Several past attempts to shut down the program have failed, but it appears as if the House Democrat fiscal 2009 spending bill, could finally put a stop to it. There are fears that ending the program could strain relations with Mexico and spark some sort of trade retaliation.
