Why is it critical to use your vehicle's headlights during overcast weather?

Answer: B — To improve visibility for yourself and other drivers

Using your vehicle's headlights during overcast weather is essential primarily because it significantly improves visibility for both you and other drivers on the road. Overcast conditions often lead to reduced light levels, making it harder to see and be seen. Headlights help illuminate the road ahead and make your vehicle more noticeable to others, which can reduce the risk of accidents and enhance overall safety. While there may be legal requirements regarding the use of headlights in certain conditions, the primary reason for turning on your headlights in overcast weather is to ensure clarity of vision and visibility. This not only helps the driver navigate safely through potentially poor conditions but also alerts other road users to your presence, thereby helping to prevent collisions.
