When should headlights be used?

Answer: B — Between sunset and sunrise

Headlights should be used between sunset and sunrise because this is when visibility is typically reduced significantly due to the absence of natural light. It is essential for drivers to use their headlights during these hours to ensure they can see the road and to make their vehicle visible to other drivers, which is crucial for safety. In addition, using headlights during these times helps comply with traffic laws and regulations that dictate the proper use of vehicle lighting. Employing headlights at the appropriate times contributes to safer driving conditions, reducing the risk of accidents that can occur in low-light situations. Using headlights solely during the day or in bright sunshine does not address the critical need for visibility during periods of darkness. Similarly, limiting the use of headlights only at night overlooks the importance of driving with adequate lighting in twilight conditions after sunset or before sunrise.
