A. The driver of a vehicle shall stop as required by section 28-855 at the entrance to a through highway and shall yield the right-of-way to other vehicles that have entered the intersection from the through highway or that are approaching so closely on the through highway as to constitute an immediate hazard, but the driver having so yielded may proceed and the drivers of all other vehicles approaching the intersection on the through highway shall yield the right-of-way to the vehicle that is proceeding into or across the through highway.

B.
