About the Caution Warning Triangle black outline icon
An equilateral triangle with softly rounded corners, standing point-up, with a thick tapered exclamation mark and separate round dot centered inside. It is the universal mark for caution and risk, so it works for form validation errors, system alert dialogs and toast messages, safety signage and workplace hazard labels, product warning stickers and incident dashboards.
The stroke on the triangle and the exclamation share the same weight, and the generous inner margin keeps the mark readable when the shape is filled with a warning color in your own palette. It pairs with info, error circle, shield and prohibited icons. Use at 16px and up; it holds its silhouette well.
This is the black outline version of the caution 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.
