I'm not referring to the jackass who started across and didn't have room to clear the intersection, and is now stuck in the middle directly in front of you. I'm referring to the driver who entered the intersection on a yellow light which then turned red, allowing your light to turn green while the other car was still transiting the intersection.
The proper course of action is not to start driving right into the path of that vehicle. Nor is honking your horn for five solid seconds the right thing to do. Actually, by law you are required to yield to any vehicle lawfully entering the intersection before your light turned green.
Don't believe me?
21451. (a) A driver facing a circular green signalBut of course nobody wants to abide by that, because they think they can just start rolling when the light turns green...
shall proceed straight through or turn right or left
or make a U-turn unless a sign prohibits a U-turn.
Any driver, including one turning, shall yield the
right-of-way to other traffic and to pedestrians
lawfully within the intersection or an adjacent crosswalk.
