A frequent wedding tradition in the United States involves the decoration of the vehicle the bride and groom drive take at the conclusion of the wedding ceremony. Typically, various ribbons and streamers are attached, and words written upon the surface of the vehicle, and often tin cans are attached to its fenders or bumpers by strings to serve as noisemakers. Jan Brunvand's "American Folklore: An Encyclopedia" speculates that the decoration of the car and its equipment with noisemakers may perpetuate the shivaree, a custom in which newlyweds were given a noisy serenade; when honeymoon travel became a custom, it made a traditional local shivaree impractical, so the vehicle is given a noisy sendoff instead.
