Red Signal Flag with Black Squares and White Stripe - Maritime & Racing Identifier #3489277 (License: Personal Use)

This stylized flag features a vibrant red field with two vertically aligned black rectangular patches and a white undulating stripe separating them. The design is standardized in international signaling systems, particularly in motorsport (e.g., Formula 1) to warn drivers of hazards on track, and in maritime contexts as a warning or “danger” signal. Its high-contrast color scheme ensures visibility under varied lighting conditions.

Used on race tracks, sailing vessels, and safety signage to communicate urgent warnings; matches user intent for identifying signal flags, understanding motorsport protocols, or researching maritime communication symbols.
