Let me just say this, if the stop sign was out, this driver was dead wrong and should be fired. That being said, in my time in package, school bus drivers were the worst drivers on the road and it wasn’t even close. I’ve seeen school bus drivers back down a street 200 yards in reverse, and countless other dumb things. I wouldn’t be surprised if the stop sign wasn’t out. Looks like a residential street with very little traffic. Maybe the driver got lazy and didn’t put it out. If they did, no excuse. Driver should be unemployed.
