Congress recently acted to repeal the test program they had initiated earlier, allowing Mexican trucks limited access to American roads under the auspices of NAFTA. The Federal Department of Transportation, not content with being smacked down by Congress, continued the program under a somewhat questionable waiver.
Keep all of this in mind when you read this story (h/t Westlander):
PHARR, Texas—A fiery crash on a bridge that spans the United States' border with Mexico left at least four people dead.
Three people in a pickup truck were killed when it plunged off the span and landed on a road below. Another person was killed in a collision with one of the trucks. Rescue workers are searching for more possible victims.
The pickup had Texas license plates. The tractor-trailers and another car involved in the wreck appeared to have Mexican tags.
