IRVING HOLDINGS, IRVING, TX: WHITE VAN #4100- AGGRESSIVE/DANGEROUS DRIVER, 10APR15 about 0500, HWY 183E. COMPANY driver terrorized me today on 183E. I passed your driver in the middle lane. When I entered his lane, he put his high beams on me, sped up, passed me and got infront of me, then slowed down. When I would put on my blinker to move into an alternate lane, he would put his blinker on to move into the SAME lane, then not move; if I moved into the lane I was indicating, he would THEN move into that lane to block me. This is not appropriate nor professional, especially for a vehicle with a handicap label in the left rear window. I'm sure IRVING HOLDINGS wants their drivers to be safe, especially with company vehicles. This driver was aggressive, intentionally creating a dangerous situation for several miles down 183E. I have reported this to the Irving police.
