Truckers rate best and worst U.S. roads, drivers

How about a dangerous exit with no warning what so ever. I 90 east to I 15 south in Montana. Interstate to Interstate short downhill sharp right with no warning what so ever. Lucky to be alive to write this and will be petitioning the Montana DOT to put up some warning signs. I wasn't the first to flip his rig and won't be the last unless some changes are made.
