Mississippi Code Title 63. Motor Vehicles and Traffic Regulations § 63-3-805

The driver of a vehicle shall stop as required by this chapter at the entrance to a through highway and 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. However, 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.

The driver of a vehicle shall likewise stop in obedience to a stop sign as required by this chapter at an intersection where a stop sign is erected at one or more entrances thereto although not a part of a through highway and 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.
