The traffic cam showed the driver stopped but it was hard to tell what else happened. If that woman was hurt so bad I can't imagine the driver just taking off after stopping. Maybe he asked if she was OK and she said she was so he left. Maybe she got hurt later. It just doesn't add up. He may have panicked because he was afraid UPS would fire him for hitting someone (what a shock).
Did we watch the same video? He didn't just bump her---he pushed her down the road. Regardless of whether she insisted that she was OK, he should have stayed until the police, EMT's and his center manager arrived on scene.
We have an intersection similar to this one in my area. The right hand turn lane traffic signal has a sign above it which states that motorists must yield to pedestrians in walkway even when they have the green turn signal.
I have to think that the pedestrian had the white walk light---who the heck would cross all of those lanes of traffic against the light--- and that our guy did not yield to her as he did not see her.
The worst thing he could have done was what he did-----he left the scene of an accident with injuries to a pedestrian.
