The Brahma Kumaris introduced the concept of using songs to manage traffic flow in several cities, particularly in India. Volunteers from the organization, often dressed in simple, distinctive attire, stand at busy intersections and sing devotional songs or slogans. These songs are designed to be catchy and easy to understand, conveying basic traffic rules and promoting courteous behavior among drivers. The underlying principle is that the soothing effect of music, combined with a spiritual message, can encourage people to follow traffic regulations more willingly.
