What is the legal requirement when driving in foggy conditions?

Using low beam headlights and reducing speed in foggy conditions is essential for safety and legal compliance. Low beam headlights are designed to illuminate the road directly in front of the vehicle without reflecting off the fog, rain, or snow, which can hinder visibility further. They provide adequate lighting to see the road and any obstacles while preventing glare that can occur with high beams, which can reflect off the moisture in the air and create a blinding effect.

Reducing speed is equally important as fog can significantly impair visibility, making it difficult to gauge distances and respond to unexpected situations. Slowing down allows drivers more reaction time and increases their chances of safely navigating through fog. This combination of using low beams and reducing speed is a fundamental traffic safety rule that helps prevent accidents in poor visibility conditions.
