Rail Crossing Warning Sign - Official Highway Safety Symbol #228948 (License: Personal Use)

The image shows a standardized U.S. Department of Transportation (DOT) rail crossing warning sign: a bright yellow diamond with bold black lettering reading “RAIL” above and “CROSSING” below, intersected by a black X-shaped crossbuck symbol. Its high-contrast design ensures visibility day or night, and it is typically mounted at grade crossings where roads intersect railway lines. This sign serves as a critical advance warning to prevent collisions between vehicles and trains.

Used on roadways approaching railroad crossings, this sign informs drivers they must yield to trains and proceed only when safe. It matches user intent for traffic safety education, driver’s license test prep, transportation engineering resources, or municipal signage guidelines.
