Which statement best explains why daylight visibility improves with certain clothing?

Answer: C — Wearing bright/retro-reflective materials

The main idea is how clothing affects how easily riders can be seen by other road users. Bright colors create high contrast with typical daytime backgrounds like pavement, cars, and foliage, so you stand out more and are noticed sooner. Retro-reflective materials reflect light back toward the source, making you appear brighter to drivers from various angles when light hits them. This combination gives the highest daytime visibility because you’re conspicuous from more directions and distances. Dark clothing blends in with the road, making you harder to spot, and relying on others to see you is unsafe. So wearing bright colors plus retro-reflective materials is the best way to improve daylight visibility.
