What do caution signs usually portend?

Caution signs are designed to alert drivers to unusual or hazardous conditions that may not be immediately apparent. These signs serve as warnings about potential risks such as road work, curves, slippery roads, or wildlife crossing. By indicating the need for increased caution, they help prevent accidents and ensure safer driving conditions.

Other signs, like those indicating dangerous intersections or stop signs, have more specific meanings and are categorized differently. While they also aim to promote safety, caution signs specifically address a broader range of less predictable hazards that require driver awareness.
