A cadre of state officials — led by Georgia first lady Sandra Deal — stopped by Langston Chapel Elementary School on Tuesday morning to talk about school bus safety. The campaign is called “Stop Means Stop,” and the focus is on emphasizing to drivers the importance of stopping when a school bus is stopped and has the red and yellow lights flashing and the stop sign extended. While that might seem like a routine topic that students would learn in school anyway, Deal and the visitors want to shine a spotlight on it because of some disturbing statistics in Georgia in recent years — particularly, that Georgia has led the nation in school bus fatalities for the past two years and appears on track to maintain that dubious distinction.
