We had a 6 yr. city Driver out of Salt Lake City that just left the yard out of the Wal-mart distribution center in Grantsville, Utah pulling a empty Long van and one of those strong gusts of wind just happened to catch him a few miles before getting back on the I80 east freeway along the Great Salt Lake, heading back to salt lake city terminal and he rolled to his right going as they said, pretty fast. The speed limit is 60mph, which safety said was too fast for the conditions, or he could have called dispatch and bob tailed back to the yard which is 47miles. He was Ok, just a little banged up and shaken a bit, and they at Fedex freight gave him a 3 year critical probation. The Kenworth Tractor is Totaled, and the trailer has a dent in the upper top and scratched along the right side. He was very lucky. The first thing the highway patrol did was check his cellphone to see if he was texting, which he wasn't. The Highway patrol did write in his report that there was nothing that he could done, other then not be there at that particular time.
