The divided highway sign is shown when approaching a section of the highway where the two opposite lanes of traffic are separated by a physical or median barrier (not before an intersection or crossing). The purpose of the divided highway sign is to alert drivers that the road ahead is divided by some type of physical or medium barrier, such as a protective barrier, a concrete barrier, or a strip of land. Drivers who encounter a divided road sign should be aware of their surroundings and obey any additional signs that may be present on the divided section of the road.
