Under what condition are drivers required to use headlights in Texas?

Drivers in Texas are required to use headlights during low visibility conditions or at night to ensure safety on the roads. This includes situations where fog, heavy rain, or other weather conditions significantly reduce visibility. The use of headlights not only helps drivers see the road ahead but also makes their vehicles more visible to others, thereby reducing the risk of accidents.

In daylight when visibility is sufficient, headlights are not obligatory; however, they are crucial as soon as conditions change, such as during twilight hours or in inclement weather. This requirement is designed to promote safety for all road users.
