When must headlights be used?

Headlights must be used from sunset to sunrise and during adverse weather conditions to ensure visibility and safety on the road. During nighttime hours, visibility decreases significantly, making it crucial for drivers to use their headlights so they can see the road clearly and be seen by other road users.

Additionally, during adverse weather conditions such as rain, fog, snow, or heavy winds, visibility can be impaired despite the time of day. Using headlights in these situations helps illuminate the road and makes it easier for other drivers to see your vehicle, reducing the chances of accidents. This practice is essential for safe driving and is often enforced by traffic laws.

Using headlights in heavy traffic is also important, but that alone does not encompass all the scenarios where headlights must be used, particularly the important considerations of nighttime and adverse weather conditions.
