What color are warning signs typically?

Warning signs are typically yellow because this color is universally recognized for alerting drivers to potential hazards or changes in road conditions ahead. The use of yellow is effective in drawing attention due to its bright and eye-catching nature, allowing it to stand out against most backgrounds, especially in daylight.

This color coding is part of a standardized system that helps drivers quickly understand the nature of the warning. For example, yellow signs may indicate curves ahead, pedestrian crossings, or other situations where drivers need to exercise caution. The consistency in signage color aids in traffic safety by providing clear, recognizable signals to road users.
