Fluorescent yellow-green signs are used for which type of warning?

Fluorescent yellow-green signs are specifically designed to alert drivers to pedestrian activity, bicycle use, and school zones. These areas are particularly sensitive and require heightened awareness from drivers since they often involve children and other vulnerable road users. The bright, vivid color of fluorescent yellow-green enhances visibility, making these signs stand out more than other warning signs, especially in low-light conditions or inclement weather.

In contrast, general traffic information, speed limits, and vehicle restrictions are typically indicated by different colored signs such as regulatory signs in white or regulatory limits in black and white. Therefore, the choice of fluorescent yellow-green for pedestrian, bicycle, and school zone warnings is intentional, emphasizing the need for drivers to slow down and proceed with caution in these areas.
