What is the visibility requirement for the unlawful to pass sign?

The visibility requirement for the unlawful to pass sign emphasizes the importance of clarity and readability. A clean and legible sign ensures that drivers can easily recognize and understand the message being conveyed. This is crucial for safety, as a clearly visible sign minimizes the chances of misunderstandings that could lead to dangerous driving decisions. Drivers need to quickly and accurately receive information about road rules, especially concerning passing, to ensure compliance with traffic laws and maintain road safety.

Options suggesting that the sign can have slight damage, be partially obscured, or bent would detract from its effectiveness, making it difficult for drivers to perceive the sign correctly, which is contrary to the safety standards required for such important signage. Thus, a clean and legible sign is essential for conveying its message clearly to all drivers.
