Texas Defensive Driving Written Practice Test

When are headlights required to be turned on in Texas?

1. Only during the day

2. From sunset to sunrise and in low visibility

3. Whenever you are on the highway

4. At all times while driving

The correct answer is: From sunset to sunrise and in low visibility

In Texas, headlights are required to be turned on from sunset to sunrise, as well as during periods of low visibility. This rule is crucial for ensuring safety on the roads, as visibility can be significantly decreased during nighttime and in adverse weather conditions, such as fog, rain, or heavy snow. Using headlights helps other drivers see your vehicle and assists you in seeing the road ahead. The requirement does not extend to only daytime travel, as having headlights on during the day is not mandated unless visibility is poor. While it is beneficial to use headlights at all times for greater visibility, doing so is not legally required under Texas law. Additionally, the need for headlights is not solely based on being on a highway, nor does it apply continuously to all driving scenarios. The specific guidelines established aim to enhance overall safety for all road users during situations where visibility is compromised.
