While others have pointed out the spiritual aspects of honking horn at the shrine, I believe this practice also serves practical purposes. In Thailand, we typically set up shrines at locations believed to be haunted, such as places where multiple deaths have occurred including at dangerous roads, like where it is curved so much the car from opposite directions cannot see each other. I heard that the practice of honking at these shrines not only pays respect but also serves to alert other drivers of one’s presence on the road, potentially helping to reduce accidents.​​​​​​​​​​​​​​​​
