I learned a long time ago to RESPECT the big rig. My car or truck will always come out the looser whether it is my fault or not. With that said, I was on the freeway in a construction zone. You know how cars pull in front of semi's. I literally saw this semi stand on his brakes and the whole truck/trailer bounce to keep from hitting these fools. I would have gave it less than a yard of space btween them.
