In lieu of last week’s string of related accidents, here’s what you should know about Georgia’s bus stop laws:

On a two-lane roadway:

ALL traffic from both directions must stop when a school bus stops for passengers. Once the bus starts flashing its red lights and its stop signs have extended from the side, it is unlawful for any vehicle to pass the stopped school bus while it is loading or unloading passengers.

On a two-lane roadway with a center turning lane:

ALL traffic from both directions must stop when a school bus stops for passengers. Once the bus starts flashing its red lights and its stop signs have extended from the side, it is unlawful for any vehicle to pass the stopped school bus while it is loading or unloading passengers.

On a four-lane roadway without a median separation:

ALL traffic from both directions must stop when a school bus stops for passengers. Once the bus starts flashing its red lights and its stop signs have extended from the side, it is unlawful for any vehicle to pass the stopped school bus while it is loading or unloading passengers.

On a roadway with four or more lanes and a center turning lane:

Previously: ALL traffic from both directions must stop when a school bus stops for passengers. After July 1, if there's either a concrete or grass median, or a turn lane, drivers traveling in the opposite direction do not have to stop for buses that are loading and unloading passengers.

On a divided highway of four lanes or more with a median separation:

Only traffic following the bus must stop when a school bus stops for passengers. According to the new state law, if there's either a concrete or grass median, or a turn lane, drivers traveling in the opposite direction do not have to stop for buses that are loading and unloading passengers.
