WSJ:

President Barack Obama and Mexican President Felipe Calderon reached a deal resolving a longstanding dispute over cross-border trucking that has subjected the U.S. to billions of dollars in punitive tariffs.

The plan, unveiled at a news conference by the two presidents, will allow for half of those tariffs to be lifted immediately. It will establish a reciprocal, phased-in pilot program that allows Mexican trucks to operate inside the U.S. provided they comply with a series of safety and driver-skills and language tests monitored by the U.S. Department of Transportation.
