A Turbo Duel, known as Riding Duel (ライディングデュエル Raidingu Dyueru) in the Japanese version, is a type of Duel which is only played by either using a "Duel Runner" or a "Duel Board" in the Yu-Gi-Oh! 5D's series and in the Yu-Gi-Oh! ARC-V series. It can be activated without the consent of the opponent by activating the Field Spell "Speed World", "Speed World 2" or "Speed World Neo", seeing as how everyone who Duels on the road is a candidate for play. Usually when a Turbo Duel starts in a stadium, an MC will shout (Japanese version only) "Riding Duel! Acceleration!".
