When should headlights be used?

• A. 30 minutes before sunrise or sunset
• B. Only when it's completely dark
• C. Only during heavy rain
• D. When you are within 500 feet of another vehicle

Answer: (A)

Turning on headlights during low-light periods helps you see the road and makes your vehicle easier for others to see. Dawn and dusk are times when lighting changes quickly, and ambient light can be just enough that you look less noticeable to other drivers. Using headlights about 30 minutes before sunrise and 30 minutes after sunset creates a safety margin, ensuring you’re visible early as light fades and as it becomes harder to spot you. The other options are too narrow. Waiting until it’s completely dark misses the early part of low light when headlights are still needed. Using headlights only in heavy rain ignores other situations where visibility is poor. And the rule isn’t about being close to another vehicle; headlights should be used whenever the lighting is insufficient for you to be seen clearly.
