I have worked road construction for most of my life and public traffic is a real PITA. Seen idiots bypass flaggers, pass the pilot car and get stuck and hold up traffic for hours while we were getting them unstuck. One time we were using a one lane township road for a detour with pilot car and a semi ran out of fuel in the middle. I broke two chains before I got a cable heavy enough to stand the strain. After that I kept a cable on the blade and had to use often.
