What is a common use for reflective road signs?

Reflective road signs serve the primary purpose of enhancing visibility at night or in low-light conditions. When light from vehicle headlights hits these signs, the reflective material bounces the light back toward the source, making it easier for drivers to see and recognize the signs from a distance. This feature is critical for safety, as it helps ensure that drivers receive important information about the road ahead, such as warnings and instructions, even when visibility is reduced.

The other options suggest purposes that do not align with the primary function of reflective signs. While making signs appealing or decorative might seem beneficial, the main goal is practicality and safety rather than aesthetics. Additionally, increasing confusion for drivers would be counterproductive to the principle of road signage, which is to provide clear and understandable guidance to ensure safe navigation.
