Large truck with trailer forces its way between a stopped school bus and the front of my vehicle to try to make a turn across traffic. There was no room for me to back up but the driver got out of his truck and started yelling at me and gesturing that he was just going to stay there until I moved. I had to slowly turn the wheel and try to maneuver around him once traffic started moving again, as he was blocking a long line of traffic during the busy after school hours
