What are yellow-green signs commonly used for?

Yellow-green signs are specifically designed to alert drivers to situations that involve pedestrians, bicycles, and school zones. This color is chosen because it is highly visible and conveys a sense of urgency regarding safety in areas where vulnerable road users are present. These signs often warn of school crossings, bike lanes, and areas with high foot traffic, helping to enhance awareness and encourage caution.

On the other hand, speed limit signs utilize a white background with black text, construction zone signs are typically orange, and prohibited direction signs use red to signify restrictions. Thus, yellow-green's distinctive purpose is specifically tailored to emphasize areas where increased attention to pedestrians and cyclists is necessary.
