What does it mean if a driver approaches a hill or curve with obstructed vision?

When a driver approaches a hill or curve with obstructed vision, it is a sign that visibility is limited, which creates potential hazards. In such situations, passing other vehicles becomes risky due to the inability to see oncoming traffic or obstacles.

Understanding that it is strongly discouraged to pass in these scenarios is crucial for maintaining safety on the road. The limited visibility means that drivers may not have adequate time to react to vehicles that could appear suddenly or to obstacles in the roadway. Therefore, exercising caution and refraining from passing is essential to avoid accidents and ensure safety for all road users.

This understanding highlights the importance of driving within one's line of sight and making safe decisions based on the road conditions. The other options suggest actions that could lead to dangerous situations, as passing in areas of obstructed vision can result in collisions or other traffic accidents.
