Difficulty: EasyDriving in Fog and Reduced Visibility

When driving through fog, operating the windshield wipers and defroster helps maintain forward visibility by removing moisture condensation from the windshield glass.

Answer: Answer

Answer

True
The statement is true because fog is tiny water droplets suspended in the air. As a vehicle moves through fog, moisture accumulates on the outside of the windshield. Simultaneously, cabin temperature differences create interior condensation. Operating both the wipers and defroster removes moisture from both sides of the glass to maintain the clearest possible view of the road.

Step-by-Step Solution

1
Identify atmospheric conditions and their effect on vehicle glass
Recognize that fog deposits moisture on the exterior windshield while atmospheric humidity forms condensation on the interior glass
Understanding why visibility decreases is necessary to take the appropriate vehicle control actions
2
Evaluate the function of wipers and defroster controls
Determine that wipers wipe away exterior water droplets while the defroster warms/dries interior glass
Both systems together ensure clear glass on both sides of the windshield during low-visibility weather
