Warning Triangle Symbol - Universal Caution Sign for Safety and Hazard Alerts #39331 (License: Personal Use)

The image displays a stylized equilateral triangle with a thick, vibrant red outline and a solid black interior, set against a pure black background. Its hand-drawn, slightly irregular stroke suggests urgency and human attention, distinguishing it from rigid vector icons. This design aligns with ISO 7010 and traffic sign standards for general warning signage.

Commonly used in transportation signage (e.g., rear vehicle warning triangles), industrial safety manuals, digital UI alerts, and emergency response materials. Matches user intent for hazard recognition, safety compliance, or iconography reference.
