About the Caution Triangle Sign black outline icon
An equilateral triangle with softly rounded corners encloses a solid exclamation mark: a tapered vertical stroke above a separate round dot. It is the standard mark for warning, hazard and required attention. Use it for error and validation messages in forms, system alert banners, safety instructions and workplace signage, machinery or chemical labels and risk sections in documents and slide decks.
The exclamation stroke is wider at the top and narrows toward the base, giving the sign weight at eye level, and the rounded corners keep it from feeling aggressive next to body text. It pairs with info, error-cross and check-circle icons for a complete status set. It stays legible down to 16px.
This is the black outline version of the caution triangle sign icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
