Which of the following is necessary to ensure visibility during low light conditions?

Using headlights properly is essential for ensuring visibility during low-light conditions. Headlights are specifically designed to illuminate the road ahead and make your vehicle visible to others. By using them correctly, drivers can see obstacles, pedestrians, and other vehicles, enhancing overall safety. Proper use includes turning them on in low-light situations such as at dusk, during bad weather, or in tunnels.

In contrast, relying on high beams at all times can actually blind oncoming drivers and create dangerous situations. Driving faster to avoid darkness does not ensure safety; it can lead to reduced reaction time and increased risk of accidents. Ignoring other vehicles' lights can result in a lack of awareness of surrounding traffic, further compromising safety. Therefore, using headlights properly is the best practice for maintaining visibility and ensuring the safety of both the driver and others on the road.
