What is a recommended safety measure for walking along a road at night?

Answer: B — Wear or carry something white

Wearing or carrying something white at night is particularly effective for increasing visibility in low-light conditions. White reflects light more effectively than most other colors, making it easier for drivers or others to see you from a distance. This is crucial for ensuring your safety when walking alongside a road where traffic is present, as it helps you stand out against the darker surroundings. Additionally, while other options may also contribute to safety—like wearing bright colors or walking with a group—using white specifically addresses the visibility issue under poor lighting conditions, which is a key concern when walking at night. Using a flashlight can provide illumination to see your path but does not enhance your visibility to others as effectively as wearing white does.
