Divided highway crossing sign

How to read it

The MUTCD requires it on side-road approaches without signals where traffic may turn both left and right onto the divided highway, on the near right corner, under the stop or yield sign or on its own post. R6-3 is the version for a four-way crossing and R6-3a the one for a T-intersection. The 2009 edition adds ONE WAY signs facing the side road where the median is 30 feet or wider. Pennsylvania's manual explains the picture: the divided highway is really two one-way roadways separated by a median or guide rail, so at the first roadway a driver can only turn right, and at the second only left. This page describes the national standard and isn’t legal advice; state law and local signs govern.

Not the yellow Divided Highway sign

The yellow diamond Divided Highway sign warns drivers already on a road that it is about to become divided. This white sign faces drivers on the road that crosses it. Pennsylvania's manual shows both.

When the 2023 MUTCD calls for it

The 2009 MUTCD required it where the median at the intersection was 30 feet wide or more. The 11th edition (2023) replaces the measurement with a test of how the crossing works: it applies where a divided highway crossing functions as two separate intersections, which the Manual says is when the paths of opposing left turns cross each other and there is room in the median for the vehicles expected to wait there. Both editions let it be left off where the highway carries fewer than 400 vehicles a day and the speed limit is 25 mph or less.
