When are motorists required to use headlights according to Title 20?

• A. Only at night
• B. When visibility is less than 500 feet
• C. During rain and fog
• D. Whenever the windshield wipers are in use

Answer: (D)

Motorists are required to use headlights whenever the windshield wipers are in use. This regulation ensures that drivers maintain visibility and can be seen by others during conditions that may impair vision, such as rain or fog, which often necessitates the use of wipers. By requiring headlights during this time, the law aims to enhance safety for both the driver and others on the road, ensuring that the vehicle is visible even when conditions might make it difficult to see.

While other options may describe situations when headlights should be used, they do not encompass the comprehensive requirement linked to the use of windshield wipers. For instance, while headlights are typically required at night and when visibility is low, the specific mention of wipers directly ties the rule to active weather conditions, making it a crucial safety measure.
