It's hard to see, but a red car made a U-turn on 380 during morning rush hour. They did it straight from the west bound lane, not the center lane, though that would still have been dangerous and illegal. East bound traffic to had to brake suddenly to avoid an accident.
Two large trucks and a car or two turning left onto 380 from 423 while the actual turn lane was also turning. During this time, 380 was down to one lane going west, adding to the potential hazard. The last truck even ran the red light while making an illegal turn.
I was already accelerating past him when he put on his turn signal. His merge style was "I'm coming over, gird your loins." People don't realize that a turn signal does not provide the right of way, and I had essentially no shoulder to move over to and a car in front that kept me from speeding up to avoid.
