Question Analysis

The question assesses the understanding of appropriate headlight use when driving in fog, specifically focusing on California's local traffic rules. In California, as in many other places, using low beam headlights is recommended during foggy conditions to improve visibility without causing glare. This is a basic safety measure to ensure that drivers can see the road without causing visibility issues for other drivers.

Correct Answer Analysis

Correct Answer: Low beams.

The correct choice is to use low beams because they are effective in providing illumination without reflecting off the fog and creating glare. High beams would reflect off the fog and actually reduce visibility, while fog lights, though helpful, should be used in conjunction with low beams to maximize safety. California Vehicle Code Section 24403 specifically advises using low beams in fog to maintain safe driving conditions.

Wrong Options Analysis

Option: Fog lights only.

While fog lights are designed for use in foggy conditions, relying solely on them without low beams may not provide sufficient illumination. Fog lights are intended to complement, not replace, low beam headlights, which are the primary source of forward visibility.

Option: High beams.

Using high beams in foggy conditions is dangerous because they reflect off the fog, reducing visibility and causing glare that can blind other drivers. This is a common misunderstanding, and drivers should avoid high beams to maintain safety in fog.
