Which practice helps visibility in adverse weather?

• A. Use high beams in fog.
• B. Drive with sunglasses.
• C. Use appropriate lights.
• D. Remove windshield wipers temporarily.

Answer: (C)

When visibility is reduced by rain, fog, or snow, using the right lights is essential. Appropriate lights—typically turning on your headlights and using low beams in fog or heavy rain—make your vehicle more visible to others and help you see the road ahead. High beams in fog create glare as the light bounces off the fog particles, making it harder to see. Sunglasses don’t reliably improve visibility in these conditions and can reduce contrast, while removing windshield wipers leaves you unable to clear your view. So, using appropriate lights is the best way to stay seen and to see better in adverse weather.
