In adverse weather conditions, why is using high-beam headlights (máximos) dangerous in dense fog?

Answer and explanation

Correct answer: B. The beam reflects off water droplets in the fog

  1. Step 1: Fog light backscatter. Step 2. High beams illuminate water droplets right in front of the driver, reflecting light back and destroying vision. Dipped beams aim under the fog layer. Answer: The beam reflects off water droplets in the fog, creating a blinding white wall of glare. Why not the others: High beams blind the driver via optical reflection.
