Traffic laws... Left turn always yields to oncoming traffic. That's why the Car stopped.

If you are inferring that the motorcyclist caused the accident, then you are wrong.

Car one slowed down, so car two went illegally around, therefore causing an accident that could have been so much worse.

Motherfucking shitheads pull this sort of idiocy far too often where I live, and even though it's caused a fair amount of injuries/fatalities, nobody is really enforcing the rules so that these pricks stop.

Fucking assholes.

Both cars started making the left hand turn. From this alone we can deduce that they had the right away, as intersections with multiple left hand turning lanes are "Go on arrow only", as opposed to most single left hand turn lanes, which are "yield". So the motorcyclist ran a red light

The car stopped because he was aware the motorcyclist wasn't stopping, so he slowed down to avoid an accident. The driver of the minivan probably didn't see the motorcyclist because of the other car, so didn't have the ability to slow down or stop.

This was just going on in my head the entire time reading that.
