Question: I read your last article about school buses and flashing lights. Can you do a reminder on passing a school bus? Answer: It is illegal to pass a school bus when its red lights are flashing and its stop arm is extended. If you are driving on a divided roadway, you do not need to stop for a school bus with red lights flashing if it is on the opposite side of the divider.
