About the Caution black outline icon
An equilateral triangle with softly rounded corners points upward and holds a thick exclamation mark: a tapered stroke above a round dot. It is the universal alert and hazard mark, ready for error and validation messages, system status banners, construction and workplace safety signage, chemical or equipment labels, and road and site maps.
The exclamation stroke narrows toward the dot, echoing traffic sign proportions, and the triangle's thin outline leaves the interior open for a fill or accent. Pair it with info, error and check circle icons. It reads clearly down to 16px.
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.
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.
