Texas CDL General Knowledge Practice Exam

What should you remember about using your vehicle's headlights?

1. Use them only in heavy traffic

2. Use them during inclement weather

3. Turn them off when passing another vehicle

4. Only use them when driving in city limits

The correct answer is: Use them during inclement weather

Using your vehicle's headlights during inclement weather is critical for safety. Inclement weather includes conditions such as rain, snow, fog, or heavy overcast skies where visibility is reduced. Headlights improve your ability to see the road ahead and help other drivers see you, which is essential in preventing accidents. When visibility drops below a certain level, using headlights is not just a good practice but often a legal requirement. In contrast, using headlights only in heavy traffic or limiting their use to city limits can hinder visibility when it's most needed. Additionally, turning off your headlights when passing another vehicle can increase the risk of a collision, as it reduces visibility for both you and the other driver. Proper use of headlights ensures a safer driving environment for everyone on the road.
