When should headlights be used?

Answer: C — In any low lighting conditions

Headlights should be used in any low lighting conditions to ensure the safety of both the driver and other road users. This includes not only nighttime driving but also situations such as dusk, dawn, or even during inclement weather like rain, fog, or snow, where visibility is reduced. Adequate visibility is crucial for recognizing obstacles, other vehicles, and pedestrians. Using headlights in low light conditions is also a legal requirement in many jurisdictions, as it helps increase the chances of being seen by other drivers and reduces the risk of accidents. Although headlights are particularly essential at night and during adverse weather, the key principle is to use them anytime natural light is insufficient to see and be seen clearly.
