What should drivers do during low visibility conditions?

During low visibility conditions, it is essential for drivers to illuminate their headlights and reduce speed. This strategy enhances safety by improving the driver's ability to see the road and other vehicles, as well as making the vehicle more visible to others. Proper use of headlights helps to cut through fog, rain, or snow, allowing the driver to detect hazards more effectively.

Reducing speed is equally important, as it gives drivers more time to react to unexpected situations that may arise in low visibility settings. Conditions such as fog or heavy rain can obscure road markings and other vehicles, and traveling at a lower speed allows for safer maneuvering.

In contrast, maintaining regular speed in low visibility can lead to accidents due to the heightened risk of not seeing obstacles in time. Not using headlights at all would severely diminish visibility, leading to potentially dangerous situations. Additionally, using high beams in fog or heavy rain can cause glare and actually reduce visibility, as the light reflects off the precipitation and creates a wall of brightness. Therefore, the combined actions of illuminating headlights and reducing speed are critical for safe driving in such conditions.
