Bottom line, sign look great, but non existing enforcements just like all signs. What percentage of drivers are caught disobeying these sign?
If you are doing it legal and are stop, only have to show the paperwork to say you were required to be in this area with a good day by the enforcer.
I have a number of truckers in my family tree and some of the stories you hear about signs are laughable, but they follow the requirements of those signs. A number been in these signs areas as they were either making a pickup or drop off and never had an issue. They never been stop period.
