Automóvil compacto estacionado al anochecer bajo la lluvia, con los faros de cruce encendidos y gotas y suciedad en las lentes.

Question 8272

Why might a vehicle's headlights illuminate the road less effectively?

  1. For both of these reasons.
  2. Because the bulbs have aged and the headlights are dirty.
  3. Because of adverse weather conditions: rain, fog, or snow.
Show answer and explanation

Correct answer: For both of these reasons.

Over time, bulbs lose brightness, and dirt on the headlight lenses lets less light through. Rain, fog, and snow further reduce road illumination by weakening and scattering the light.
