The vehicle’s game statistics appear below. It acts on your turn, functioning as a controlled mount while you ride it (as defined in the rules on mounted combat). You determine its appearance, which includes wheel count; your choice has no effect on its game statistics. It disappears if it is reduced to 0 Hit Points or after 8 hours. You can dismiss it early as an action.

Once you create a vehicle, you can’t do so again until you finish a Long Rest or expend a spell slot to create one. You can have only one vehicle at a time and can’t create one while your vehicle is present.
