When there's a train coming and your rear end is close by the tracks, you have to clear out. My side had green on left and through. Some dumbo in an International Amtran school bus from oncoming decided his red turn light meant permissive green and nearly took me and a few motorists out.
Thank God for ABS to be working.
tl;dr: Dude ran a red light, was lucky I wasn't on the Honda.
