Scenario: Intersection; one lane w/shoulder in each direction; I'm first in line turning left; the car going in the opposite diection is also turning left; he has a line of cars behind him. The light turns green. I determine I can make my turn, but a guy in the opposite direction aggressively pulls onto the shoulder to pass his left turners on the right and he engaged me during my turn and he leaned on the horn and yelled at me. Is he allowed to pass his left turners on the right shoulder?
