When approaching a "Keep Right" sign, the driver should first look for any traffic islands or medians ahead. This is crucial because the purpose of the "Keep Right" sign is to direct vehicles to stay to the right side of an obstacle, which is often a traffic island or median. Identifying road features ahead allows the driver to prepare adequately to navigate safely around these obstacles and maintain proper positioning on the road.

Maintaining awareness of traffic islands or medians is essential for safe driving, as these structures are designed to guide traffic flow and enhance safety by preventing head-on collisions. By being alert to these features, drivers can make informed decisions about how to maneuver their vehicle in accordance with the rules of the road.
