Under what conditions should you turn on your headlights?

• A. In low visibility, at dusk/dawn, and whenever required by conditions.
• B. Only after sunset.
• C. Only when it rains.
• D. Only when driving on the highway.

Answer: (D)

The main idea is that headlights are a safety tool to help you see the road and be seen by others, and you should use them whenever visibility is reduced or light is low. This includes not only nighttime but also times when it’s dim or conditions make seeing more difficult. So you turn on headlights in low visibility, at dusk and dawn, and whenever the driving conditions require it (for example, during rain, fog, or snow, or when windshield wipers are in use). Choosing to turn them on only after sunset misses daytime low-visibility cases; turning them on only when it rains misses other poor-visibility situations like fog or snow; and turning them on only on the highway ignores other roads where visibility can still be poor and other drivers need to see you. Using headlights whenever conditions require helps ensure you can react sooner and others can notice you sooner.
