Bus 7174 at approximately 3:15PM on Ave U and Gerritsen ave literally pushed me with my school bus off to on coming traffic which I had the right of way because he was on the side of the street unloading passengers. He not only fought to get in front of the school bus but he also ran a 2 red lights and as he approached Ave U and Flatbush went into a turning lane only to get in front of all the cars. He did not use a signal when he was leaving the curb as well. As a 31 year veteran driving buses I feel this is totally unexceptable.
