Discription of Events: The incident happened around 7:50am and was caused by (I think a man) driving a white commercial truck with the B&W Trailer Rental Logo on back. While driving to work on Weston Pkwy in Cary, NC in the left lane, this large truck was beside me in the right lane and started to merge into the left lane in which I was in. I honked my horn to let them know I was there but they continued to merge and forced me into the median while I continued honking to try to get them to stop. There was a decent amount of traffic which made it nearly impossible to avoid them in any other way; if I stayed where I was, they would have crashed into me. This is not a matter of a blind spot because I made it very obvious that I was there. I drive in traffic every morning and afternoon and experience a lot of ignorance and unnecessary road rage and just go on about my day, but this needs to be reported and the person driving that B&W commercial truck needs to be reprimanded. Thank you for your time.
