Railroad Crossing Sign - Official Warning Symbol for Tracks #228935 (License: Personal Use)

The image shows a classic U.S. railroad crossing warning sign: a bright yellow circle with a thick black border, two diagonal black bars forming an "X", and the letters "RR" on either side. The high-contrast design ensures visibility day or night, and the symbol is standardized by the MUTCD (Manual on Uniform Traffic Control Devices). It’s mounted at road intersections near active rail lines to prevent collisions.

Used on roads approaching railway crossings; serves as a passive warning device where no active signals (like gates or lights) are present; matches user intent for traffic safety education, signage identification, or transportation regulation reference.
