PHOENIX (CBS 5) - Being a truck driver has its challenges. There are some roads in Phoenix trucks are permitted and some places where they are not. Usually, there is signage with commands for truck drivers to follow.
In Phoenix, there are truck routes where the road is designed for heavy loads and wide turns. Roads not set up for large trucks have signs which read "NO Thru Trucks." Those signs are often ignored by truck drivers.
