§ 40-6-50. Driving on divided highway, controlled-access roadways, and emergency lanes
(a) As used in this Code section, the term "gore" means the area of convergence between two lanes of traffic.
(b) Every vehicle driven on a divided highway shall be driven only upon the right-hand roadway unless directed or permitted to use another roadway by official traffic-control devices or police officers. No vehicle shall be driven over, across, or within any dividing space, barrier, gore, paved shoulder, or section separating the roadways of a divided highway; except that a vehicle may be driven through an opening in such physical barrier or dividing space or at an established crossover or intersection unless specifically prohibited by an official sign, signal, or control device. No person shall drive a vehicle onto or from any controlled-access roadway except at such entrances and exits as are established by public authority. Except as provided for in subsection (c) of this Code section, no vehicle shall be driven in an emergency lane except in the event of an actual emergency.
(c) For purposes of this subsection, "transit bus" means a bus used for the transportation of passengers within a system which is operated by or under contract to the state, a public agency or authority, or a county or municipality of this state. If the commissioner of transportation permits the use of emergency lanes of a controlled-access roadway by transit buses in the metropolitan Atlanta nonattainment area, the commissioner shall designate on which controlled-access roadways the use of emergency lanes by transit buses may be allowed and upon such designation the commissioner shall only permit the use on that emergency lane of a transit bus with a seating capacity of 33 passengers or more. Transit buses authorized to use the emergency lanes under this subsection may be operated on the emergency lane only when main lane traffic speeds are less than 35 miles per hour. Drivers of transit buses being operated on the emergency lanes may not exceed the speed of the main lane traffic by more than 15 miles per hour and may never exceed 35 miles per hour. Drivers of transit buses being operated on the emergency lanes must yield to merging, entering, and exiting traffic and must yield to other vehicles on the emergency lanes. Transit buses operating on the emergency lanes must be registered with the Department of Transportation.
(d) Nothing in this Code section shall prohibit the use of a FlexAuto lane in the manner permitted under Code Section 32-9-4.1.
