In which situation should your headlights be turned on?

Headlights should be turned on when visibility is reduced and at night to ensure that you can see the road clearly and be seen by others. In conditions such as fog, rain, or darkness, using headlights enhances your visibility and helps you to notice obstacles, road signs, and other vehicles. This practice is essential for safety, as driving without adequate illumination in these conditions can increase the risk of accidents.

Using headlights at night is particularly important since darkness significantly reduces the ability to see. It's also important to understand that even if conditions are slightly illuminated, such as in twilight or during inclement weather like rain or fog, having headlights on provides an extra margin of safety.

Other scenarios such as using headlights only during rainy weather or only when other drivers are present do not account for the full range of conditions under which headlights are necessary. Well-lit areas may also provide sufficient visibility, but this does not negate the need for headlights in poor visibility situations. The emphasis on using headlights whenever visibility is compromised, as well as during nighttime driving, underscores their role in enhancing overall road safety.
