When is it required to use headlights while driving?

Headlights are required to be used between sunset and sunrise, as well as during conditions where visibility is reduced, such as adverse weather conditions like rain, snow, fog, or when driving in tunnels. This requirement ensures that drivers can see the road ahead clearly while also making their vehicle visible to others, significantly reducing the risk of accidents.

Using headlights in these situations enhances safety by improving visibility for both the driver and other road users. It's important to recognize that simply relying on daylight or being on a highway does not cover all scenarios where headlights are necessary. For example, driving during the day does not absolve a driver from turning on their headlights in conditions that are not well-lit or when visibility is compromised.
