When is it required to use your headlights?

Answer: C — Both during adverse weather conditions and at night

Headlights are a crucial safety feature for any vehicle, and their use enhances visibility for both the driver and other road users. It is required to use your headlights during adverse weather conditions, such as rain, fog, snow, or anything that reduces visibility. This ensures that you can see clearly and that other drivers can see you, helping to prevent accidents. Using headlights at night is also mandatory as visibility is drastically reduced in darkness. When driving at night without headlights, drivers are at a higher risk of being involved in collisions due to limited sight distance and the inability of others to see them. Combining these two requirements highlights the importance of using headlights under both sets of conditions, thus making the third option the correct answer. It reinforces safe driving practices and legal expectations that help protect everyone on the road.
