(2) The driver of any vehicle which is stopped as close as practicable at the entrance to the crosswalk and to the far right side of the roadway, then at the entrance to the intersection in obedience to a red or stop signal, may make a right turn but shall yield the right-of-way to any pedestrian and other traffic proceeding as directed by the signal at the intersection.
