What type of area typically indicates a blind corner?

A blind corner often occurs in areas where road bends are obstructed by natural or physical elements. This situation can impede a driver’s view, creating potential hazards as vehicles or pedestrians may be approaching from the opposite direction without being visible until it's too late.

In the context of the choices, bends in the road with obstructions, such as trees, are prime examples of this scenario. The presence of trees or other tall objects can significantly limit a driver's line of sight, making it difficult to see oncoming traffic or obstacles until very close to the corner. This creates a high-risk situation for collisions.

While other options depict various driving environments, they either suggest good visibility or include features that typically foster safe driving conditions. For example, open highways usually provide clear visibility, residential areas, while busy, are typically designed with lower speed limits and pedestrian crossings, and roads with multiple lanes would generally have better signage to guide drivers, reducing the chances of encountering blind corners.
