Kinda reminds me of when I was training a guy many years ago I woke up with him asking for help in a motel parking lot. When I asked why he said the sign said "All trucks must use exit __ to Scranton. Which after I thought about it, is a little confusing. Before someone asks why was I sleeping we were in the team phase of his training.
If they want all trucks in, them turn off the pre pass system. New Mexico does it all the time in Anthony and Lordsburg on 10 at night when they are bored.
