Outlined rounded warning triangle containing an exclamation mark
About the Caution black outline icon
An equilateral triangle with softly rounded corners carries a double outline, and inside it a vertical bar sits above a separate dot to form an exclamation mark. It is the universal cue for caution, hazard and required attention. Use it for form validation errors, system alerts and toasts, safety notices in manuals, construction and factory signage, and risk sections in reports or dashboards.
The inner triangle echoes the outer edge, which makes the sign read as a physical plate rather than a flat shape, and the wide margins keep the exclamation centered. It pairs with error cross, info circle and prohibited icons in alert sets. Keep it above 16 px so the mark's dot stays visible.
This is the black outline version of the caution icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
