When driving in fog, using low beam headlights and reducing speed is crucial for safety. Low beam headlights are designed to illuminate the road directly in front of the vehicle without causing a glare that can reflect off the fog, which can obscure visibility and make it harder to see. This allows the driver to see the road and any obstacles more clearly.

Moreover, reducing speed is essential because fog can significantly limit visibility and impairs your ability to see other vehicles, road signs, or potential hazards. By driving slower, you have more time to react to any unforeseen circumstances, reducing the likelihood of accidents.

Increasing speed in fog, using high beam headlights, or relying solely on hazard lights can create dangerous conditions. High beams can reflect off the fog, creating a wall of light that can hinder visibility, while hazard lights do not provide illumination of the road and can confuse other drivers. Sticking strictly to the speed limit in such conditions may not account for the reduced visibility and the need for increased caution. Thus, the safest approach is to use low beam headlights and reduce your speed appropriately.
