When should your headlights be turned on?

The correct choice is that headlights should be turned on in low visibility conditions such as rain or fog. This is crucial for both enhancing your own visibility on the road and making your vehicle more visible to other drivers. In poor weather conditions, such as rain or fog, natural light can be significantly reduced, making it harder to see both the road and surrounding vehicles. Using headlights in these situations helps to cut through the haze and improves overall safety.

While it is true that headlights are required to be used at night, relying on headlights only during the night does not address the critical need for visibility in adverse weather. Similarly, using headlights solely in residential areas does not account for the potential for low visibility conditions that can occur anywhere, including highways. Keeping headlights on during situations of reduced visibility ensures that drivers can operate their vehicles safely and be seen by others, which is a fundamental aspect of defensive driving.

Additionally, it is often a legal requirement in many regions to use headlights during certain weather conditions, further underscoring the importance of this practice.
