Alert Sign Triangle black filled icon

About the Alert Sign Triangle black filled icon

This icon is the standard caution triangle: an equilateral triangle with softly rounded corners, enclosing a heavy tapered exclamation mark and a round dot beneath it. It signals danger, system errors, unsaved changes and anything a user must read before continuing. Use it in form validation messages, toast and modal alerts, machinery and chemical safety labels, dashboard monitoring panels, and road or workplace signage artwork.

The exclamation is weighted wider at the top and tapers downward, giving the mark visual force inside the thin triangle outline. The rounded vertices keep it friendly enough for interface use. It pairs with info, error-circle and check-circle icons in the same status family. Place it at 16–24 px beside inline messages, larger for full-screen warnings.

This is the solid black filled version of the alert sign triangle icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
