People are a pain in the a**. Work on the side of the road for any length of time and you would be amazed at what you see.
I remember one time my uncle was backing his dump truck up to a trailer and I got out to stop traffic on a quite side street. No traffic until a car came up and I motioned to stop. The lady could clearly see a big freaken dump truck starting to back across the road and me, but swerved around me, my uncle seeing this out of his passenger window just kept backing up, **** em is his attitude. She just managed to get behind the truck clipping one mirror on the back, and damaging one wheel on the curb. Never stopped.
A few years ago on a sewer invert job that I wasn't on, but was on a busy road they had two cops directing traffic. Some boozo in a big dually Ram with massive towing mirrors decided he wasn't going to wait for one of the guys to get out of the way when they closed the lane to let equipment pass and reopened it. So he just went threw and the mirror struck one of my uncles workers.
The cops called their buddy's and about a mile up the road the guy was pulled over, taken out of his truck, and arrested for a hit and run in a work zone.
People are a PITA, when you have a work zone set up in a street. Generally you want to throw your shovel threw a cars window several times a day.
