What do yellow signs typically indicate?

Yellow signs are primarily used to provide warnings about unexpected or potentially hazardous conditions on the road. They alert drivers to situations that require caution, such as curves, pedestrian crossings, road work, or intersections. The bright yellow color is designed to capture attention and indicate that drivers should be particularly vigilant in that area.

In contrast, signs that indicate traffic regulations and commands are generally white or red, conveying mandatory actions or prohibitions. Information about nearby facilities is typically depicted with blue or green signs. Restrictions on vehicle types are communicated through specific regulatory signs, which do not use yellow for their messaging. Thus, the role of yellow signs is clearly focused on warning and enhancing safety by preparing drivers for changes in road conditions.
