The US has delayed allowing Mexican trucks to deliver products deep into the U.S for 11 years, despite NAFTA’s provisions, citing safety concerns. NAFTA, signed in 1994, had called for Mexican trucks to have unrestricted access to highways in border states by 1995 and full access to all U.S. highways by January 2000. Canadian trucks have no limits on where they can go. On Friday October 21st the first truck, carrying electronics, was scheduled to enter the U.S., as safety concerns have been addressed with electronic tracking equipment. Mexico has cancelled punitive tariffs on some US goods in respons.
Some U.S. congressmen and U.S. labor continue to oppose this. http://www.nbcsandiego.com/news/local/1st-Mexican-Truck-to-Enter-US-Interior-Within-Days-132179983.html
