No Horn Sign - Official Traffic Prohibition Symbol for Quiet Zones #2010055 (License: Personal Use)

The image displays two variants of the internationally recognized “No Horn” traffic sign: a colored version with a red circle, diagonal slash, and black horn icon, and a monochrome outline version suitable for printing or vector applications. Both convey the prohibition of using vehicle horns in designated areas to reduce noise pollution. These signs are commonly installed near sensitive locations like hospitals, schools, and residential neighborhoods.

Used on roadways, municipal websites, traffic regulation pages, and public safety campaigns to inform drivers of horn restrictions; matches user intent for understanding traffic signage, compliance, or designing regulatory materials.
