Yellow Warning Sign - High-Visibility Caution Symbol for Safety Applications #3335400 (License: Personal Use)

This image displays a solid, vivid yellow square enclosed by a thick black border, following standard color contrast guidelines for visibility and hazard communication. The design is minimalist yet universally recognized in traffic, industrial, and digital interfaces to denote caution, pending action, or non-critical alerts. Its uniform fill and clean edges ensure legibility at distance and across devices.

Used in road signage (e.g., temporary warnings), workplace safety posters, software UIs (e.g., system alerts), and instructional materials where immediate visual recognition of caution is required. Matches user intent for finding standardized warning symbols or designing accessible alert components.
