Roadway signage is designed primarily for safety and effective communication with drivers. A critical feature of such signage is the use of reflective materials, which enhance visibility, particularly at night or in low-light conditions. This reflective quality allows light from vehicle headlights to illuminate the signs, making them easier to see from a distance.

In addition to materials that increase visibility, standardized symbols are an essential aspect of roadway signage. These symbols must be universally recognizable to ensure that all drivers, regardless of linguistic background, can quickly understand the information being conveyed. Standardization plays a key role in traffic safety, as it helps maintain uniformity across different regions, allowing drivers to interpret signs consistently.

Neon colors, while they can be bright and eye-catching, are not typically utilized in standard roadway signage, as they may not provide the best visibility compared to the reflective materials favored in traditional signage design. Moreover, while digital displays are increasingly seen in some applications, particularly in dynamic message signs, they are not a standard feature of all roadway signage. Non-reflective surfaces are generally avoided in traffic signage because they can compromise visibility, especially during nighttime or adverse weather conditions. Therefore, the emphasis on reflective materials and standardized symbols underlines the key principles of safety and communication in effective roadway signage
