Discription of Events: A Greenway landscape company truck heading south on i5 in Salem, merges on into right lane, Im traveling in an empty 4 axle semi, pulling 4 axle trailer in the center lane, minding my own business. Its 6:07 in the morning, traffic is light. There was nobody in front of him for at least a mile, he cuts 1 car length gap in front me and slows me down, I get over to pass him as Im on cruise control, he speeds up and doesnt allow me to pass. So I sped up and got in front of him "barely". He gets over passes me and cuts me off this time almost taking out my bumper and tries brake checking me but Im not slowing down, he realized that and I grabbed my phone to start recording, and he slowly pulls away gets back into the right lane and takes an exit. He really had to do all that? To be on the freeway for 2 miles or less with no traffic anywhere near him?
