Been a couple years ago we were pulling north on I81 in the right lane at about 65 in a 70 zone. Two vehicles, a pickup and a small car were coming down the entrance ramp obviously slower than I was moving, there was traffic passing in the left lane so I couldn't move over but the PU guy puts on his signal, which I guess he thought gave him the right of way, and pulls on over. I started slowing down and all of a sudden the idiot hits his brakes hard to let the car that was behind him on the ramp get onto the Interstate in front of him. I think someone up above was watching over us that day because I have no earthly idea how we managed to keep from hitting him...I was so close I could hardly see the bed of his truck. I would loved to have shown him that I thought he was number "one" but honestly I was so busy trying to control the rig I forgot all about signing him.
