What should be done if visibility is poor while driving?

When visibility is poor while driving, the most prudent action is to reduce speed and increase attention to your surroundings. This response is essential because slower speeds provide more time to react to unforeseen obstacles or changes in traffic conditions, which is crucial for safety. Additionally, increasing attention allows the driver to better assess the environment, making it easier to navigate through reduced visibility caused by factors like fog, rain, or darkness.

Maintaining current speed and relying on intuition may lead to dangerous situations since reduced visibility impairs judgment and reaction times. Simply relying on headlights without adjusting other driving behaviors does not address the increased risk of accidents in low-visibility conditions. Ignoring traffic signals is inherently unsafe and could lead to collisions or other hazardous scenarios, further emphasizing the need for rational decision-making when visibility is compromised. Therefore, the correct approach is to minimize speed while enhancing situational awareness to ensure safe driving under challenging conditions.
