About the Danger Warning Triangle black outline icon
An equilateral triangle with rounded corners frames a bold tapered exclamation mark above a round dot, the standard hazard sign layout used worldwide. It flags errors, cautions and required attention, which makes it a fit for form validation messages, safety notices, system and device alerts, machinery labels and construction site signage.
The heavy filled exclamation contrasts with the thin triangle outline, so the warning registers before the outer shape does. Rounded corners soften it enough for interface use. Pair it with info and error circle icons in a status set; it stays legible down to 16 px.
This is the black outline version of the danger warning 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.
