A Cart Pony is a Human Pony whose specialisation is drawing a Driving Cart under the direction of a Driver. Cart work emphasises steady pace, obedience to voice and rein, and coordination between Pony, Driver and cart.

Cart Pony work is one of the signature disciplines of Pony Play, especially at events with the space and equipment for driving.

Cart Pony practice requires attention to physical safety, gear fit and pacing. Standards vary by Stable and event.
