Railroad Crossing Sign - Official RR Warning Symbol for Safety #1806320 (License: Personal Use)

This high-contrast circular sign features a vivid yellow background with bold black lettering “RR” and two intersecting diagonal bars forming an “X,” universally recognized as a railroad crossing warning. The design follows federal MUTCD standards to ensure maximum visibility and immediate recognition by drivers, cyclists, and pedestrians. Its reflective properties enhance nighttime safety when mounted at grade crossings.

Used at public road-rail intersections in the U.S. and other countries, this sign is typically mounted on posts or overhead gantries to warn of approaching trains. It matches user intent for traffic safety education, driver’s license exam prep, transportation signage reference, or municipal infrastructure documentation.
