The idea is that you need to take the yellow box in a bucket on one side of the street, go and put it in a bucket on the other side. But as idiots just go with the flags even Kёrklande not found, then each bucket had to write the following mathematically precise inscription: "62 people in the city Kёrkland suffered or died at pedestrian crossings. Of those with a flag - 0 ».

Today, flags are used instead of the traffic lights in Seattle, Salt Lake City and Berkeley.
