In a construction zone on I-77 southbound. The operator was traveling at excessive speed in the middle lane. The middle lane of traffic began to slow and he aggressively switched back into the right merging lane with turn signal. He than proceed to place his left hand out of the driver side window and waive a vulgar signal to passing traffic. Noticing that he was in a merging lane he proceeded to aggressively merge back into the right lane nearly causing a accident. Traffic around him slowed and he proceed to cut across 3 lanes to the far left lane. This lane was also ending due to construction and merges down to 2 lanes. He realized his second mistake and it was at this point that he merged directly into my lane without use of turn signal. I merged into the far right lane to avoid his aggressive lane switch and proceeded to pass him on the right as traffic slowed. I accessed my phone and took a picture of his truck id on the right side. He noticed that and proceeded fan a vulgar hand signal at my vehicle. I merged to the right and was able to get some distance from him but traffic slowed and he passed my vehical and merged back into my lane. I merged back into the left lane to proceed down the highway. His truck was now about 1/8 of a mile ahead of me in the center lane. As traffic speed increased I eventually caught up with him. When I was within 10' or less he swerved back into my lane without using turnsignal cause me to nearly lose control of my vehicle. The highway went back to 3 lanes and I was able to manuver around him and proceed to my destination. I tried to contact the company (DDM Transport Salt lake City, UTAH) but their listed number is disconnected. I did google the company and found this link that was another complaint very similiar experience to mine earlier this month. This guy drives a 53' semi like a Ferarri.

In a construction zone that was 45mph instead of the usual 55 mph, he rode everyone's tail while whipping his trailer back and forth between lanes. There was slow traffic everywhere on highway 370 in Nebraska and no where to speed up yet he continued to drive in the most unsafe and aggressive way possible. Then he decided to this to all the drivers he passed. Check out the photo.
