School bus stopped as I was passing it. It hadn't turned its red lights on yet and it hadn't come to a full stop until after I had started passing. I didn't speed up or anything, I had slowed down heavily and was waiting on it to stop but it didn't until after I had already passed the front end of it. I was in the opposing lane so it's not like I tried to go around it. Now I'm freaking the f**k out because I'm scared shitless that I'm gonna get a citation
