About the Attention Sign Triangle black outline icon

An equilateral triangle with softly rounded corners frames a tapered exclamation mark whose stroke narrows toward a separate round dot below. The shape is the universal caution cue, so it fits error banners, form validation messages, low battery or storage alerts, safety signage in facility documents and hazard labels on packaging or equipment manuals.

The triangle points upward and fills the full canvas, giving the mark a wide stable base, while the exclamation sits centered with generous margin on all three sides. It pairs with info circle, question mark and shield icons in the alert set. Apply a single amber or red tone to the whole shape rather than the stroke alone.

This is the black outline version of the attention sign triangle icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.

It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
