What is required for sign legibility according to the standards?

• A. High visual clutter
• B. High legibility
• C. Minimal use of colors
• D. Small letter sizes

Answer: (B)

High legibility is essential for road signs because it ensures that drivers can easily read and understand the information being conveyed, particularly at a distance and at speed. Legible signs contribute to overall road safety by allowing drivers to make informed decisions quickly and react appropriately to the information presented.

Standards for sign legibility emphasize characteristics such as clear fonts, adequate contrast between text and background, appropriate letter sizes, and effective spacing. These aspects are critical in ensuring that the message of the sign is conveyed promptly and without ambiguity.

In contrast, high visual clutter can distract drivers from important information, while the use of minimal colors can limit the effectiveness of signage in capturing attention or conveying meanings. Small letter sizes can hinder readability, especially for drivers who are further away from the sign. Therefore, while these characteristics might be considered in different contexts, high legibility remains the primary requirement for effective sign design.
