Discription of Events: This driver cut across a highway on-ramp and another lane of heavily congested traffic, nearly crashing into me just so he could get in front of me. I was visibly upset after nearly being crashed into and yelled to this driver that I would report him to his employer since he was driving a company truck. He yelled to me that he was the boss and then proceeded to slam on his brakes when traffic got moving and I was behind him. He weaved in and out of traffic in an attempt to prevent me from taking a photo of his company logo. The company is called Whitney Northeast Construction Products and is based out of Boston, MA
