You have to see this to believe it.
A Texas highway was brought to a standstill during rush hour after an unbelievable 18-wheeler accident.
The truck was barreling down the freeway when one end of its truck bed slammed into an overhead highway sign. Apparently, the trailer's hydraulic arm spontaneously activated and -- unbeknownst to the truck driver -- lifted the bed up into the air.
Luckily, no one was injured.
