Discription of Events: Be careful the driver of this truck was tailgating me not obeying the 2-4 second space cushion on a 2 lane highway. When the two lanes opened to a passing corridor he was staring at me as he went to pass me with a trailer and a catapiller on it with a large drill. He was at speeds near 70mph in a 55 on a two lane highway. I was unable to take photos cause I was driving. I fear their will be consequences for reporting.
