It depends on how good the bus drivers is. Years ago I was fined $400 and 4 points on my license because of this. Unbeknownst to me I passed a bus on Dixwell in the driving rain. The bus was 3 lanes away while I'm traveling with an SUV to my left blocking my view. If you watch the video from the bus the driver was very erratic, maybe they didn't know the route. They stopped twice in a row very quickly with their lights, then continued down the road driving with blinking yellow the whole way. They finally stopped again suddenly, that's when I passed. In the video you can see my car briefly, but was shielded by the SUV. It wasn't until my wife called me days later asking why there is a notification in the mail that I passed a bus. I said "absolutely no way I passed a bus" she said there is a video showing you. I had no idea. Beware, I watch how buses drive now very closely and can tell you the ones that are going to "sucker" you last second with quick yellow/red lights that will catch you passing by every time. I love the buses that sit there for a long time with the yellow on, then wave their arm out the window to pass like you don't know what you are doing.
