A. Through Highway: After the driver of a vehicle has stopped at the entrance to a through driveway, such driver shall yield the right of way to other vehicles which have entered the intersection from said through highway or which are approaching so closely on said through highway as to constitute an immediate hazard, but said driver, having so yielded, may proceed and the drivers of all other vehicles approaching the intersection on said through highway shall yield the right of way to the vehicle so proceeding into or across the through highway.
B. Stop Intersection: After the driver of a vehicle has stopped in obedience to a stop sign at an intersection where a stop sign is erected at one or more entrances thereto, although not a part of a through highway, such driver shall proceed cautiously, yielding to vehicles not so obliged to stop which are within the intersection or approaching so closely as to constitute an immediate hazard, but may then proceed. (1975 Code § 8-5-9)
