WH2208 swerving to slow cars on a hill caused multiple people to almost wreck. One truck was forced to pass in grass median. Speeding in construction zone and being dangerous in 80,000lb truck. He then decided when I told him he was a idiot. To have me pull over which resulted in him hiding in his truck and blaming me for reacting the way I did. I almost ended up in a pile up a few years ago and to see this being done as bullying, not fog or speeding drivers is ridiculous. I hope they dont wait until he kills someone by being immature to pursue this.
