Question 4808

It is important to keep the headlight lenses clean because dirt...

  1. Removes the rough texture formed by the prisms on the outer surface.
  2. Causes corrosion of the lens, reducing its watertightness.
  3. Changes the direction of the light beams, causing glare.
Show answer and explanation

Correct answer: Changes the direction of the light beams, causing glare.

Dirt on the headlight lens absorbs some of the light and scatters some of it in all directions. You light up less of the road, and light directed upward or to the sides can blind other drivers. In the image, the headlight lens is splattered with dirt.
