Back home... safely, thankfully! This all happened at about 3pm... we were at a merging of two highways, and he just kept on coming -- regardless of the fact I was in the lane he was merging into! (...just about even with his cab at the time!) I moved over, quite upset, and laid on my horn -- to which he replied with his! (Dennis, I could have used the train horn about then!

)
Pretty pissed about this point, I turned on my turn-signal -- tried to warn him -- and nearly lost my spare when I whipped to my right and into his lane. He wasted no time to jolt left and pass me -- while we shared "salutes". As soon as he got me even with the middle of his trailer, he weaved into my lane trying to force me off the road -- through the car on my right!
This was the point in which I forwent my exit (in less than 1 mile) and chased the bastard down until we could get all the numbers off the back of the truck. As soon as he sped up and tried to lose me, he cut off another car (this time a Taurus) I didn't hesitate to call -- and give them a rundown of the incident that had just happened.
I doubt that any action will be taken, but the WOMAN on the other end -- the safety control officer -- assured me that he would be losing his job over it.

Who really knows...
