When must headlights be used?

• A. 30 minutes after sunset and 30 minutes before sunrise
• B. Only during heavy rain
• C. When driving in city limits
• D. Only at night

Answer: (A)

Using headlights 30 minutes after sunset and 30 minutes before sunrise is essential for ensuring visibility and safety on the road during times when natural light is diminishing or absent. This period corresponds to twilight times when it might not be completely dark, yet visibility can be significantly reduced. By using headlights during these times, drivers not only improve their own visibility but also make their vehicles more noticeable to other road users, including pedestrians and cyclists.

Moreover, regulations generally dictate that headlights must be used in conditions of reduced visibility, which can occur not just at night, but also during inclement weather such as rain, fog, or snow. Thus, understanding the requirements around using headlights is critical for safe driving practices, especially during those key twilight periods.
