When must headlights be turned on in Texas?

Headlights must be turned on from sunset to sunrise and in bad weather because they are essential for visibility during low-light conditions and adverse weather situations. This requirement ensures that drivers can see the road clearly and be seen by other vehicles, which is crucial for safety. Nighttime driving poses challenges due to reduced natural light, and turning on headlights improves visibility for both the driver and others on the road.

Furthermore, in bad weather conditions, such as rain, fog, or heavy clouds, visibility can be significantly impaired. Utilizing headlights during these times helps enhance the driver's ability to see adequately and alerts other drivers to their presence. This rule is an important safety measure designed to reduce accidents and improve overall road safety.
