Explanation:

This sign is called the Divided Highway sign, it simply means the highway ahead will be divided.

You see this sign when you approach a section of the highway where the opposing flows of traffic are separated by physical barrier, it could be a median or a round-about.

it is also important to note that it is not placed close to intersections, even if the intersection has a temporary median or barrier.

Lastly, note that with the above explanation it is clear that on sighting this sign you must remain on the right lane and not try to overtake as this may result in an accident with the barrier.
