Bus License #S2M676, Bus #66 on March 31, 2015 on Route 21 merging onto Route 20 at around 8AM should learn how to drive more carefully with children in the bus. Thank goodness there were no children in the bus when she cut me off. There was traffic and she wanted to get in front of me, so she went around me and did not put a signal on. Very rude and very dangerous if I had been going faster, ESPECIALLY if there were children in there.
