Jeeps have rubber ducks on them as part of a fun and kind tradition known as "Jeep ducking" or "Duck Duck Jeep." This custom originated in 2020 when Allison Parliament left a rubber duck with a positive message on a Jeep as an act of kindness after a difficult day. The idea quickly went viral among Jeep owners, who now leave rubber ducks on other Jeeps to spread goodwill and connect with fellow Jeep enthusiasts. Owners often decorate their dashboards with many rubber ducks, called "duck ponds," symbolizing community and positivity. The trend has grown into an international phenomenon celebrated by Jeep owners worldwide.
