Driving, when applied to horses, ponies, mules, or donkeys, is a broad term for hitching equines to a wagon, carriage, cart, sleigh, or other horse-drawn vehicle by means of a harness and working them in this way. It encompasses a wide range of activities from pleasure driving, to harness racing, to farm work, horse shows, and even international combined driving.
For horse training purposes, "driving" may also include the practice of long-lining (long reining), wherein a horse is driven without a cart by a handler walking behind or behind and to the side of the animal. This technique is used in the early stages of training horses for riding as well as for driving.
Horses, mules and donkeys are driven in harness in many different ways. For working purposes, they can pull a plow or other farm equipment designed to be pulled by animals. In many parts of the world they still pull carts, wagons, horse-drawn boats or logs for basic hauling and transportation. They may draw carriages at ceremonies, such as when the British monarch is Trooping the Colour, as well as in parades or for tourist rides.
Horses can race in harness, pulling a very lightweight one-person cart known as a sulky. At the other end of the spectrum, some draft horses compete in horse pulling competitions, where single or teams of horses and their drivers vie to determine who can pull the most weight for a short distance.
In horse show competition, the following general categories of competition are seen:
Combined driving, an internationally recognized FEI competition where horses compete in one, two, and four-horse teams, pulling appropriately designed light carriages or carts. They are expected to perform an arena-based "dressage" class where precision and control are emphasized, a cross-country "marathon" section that emphasizes fitness and endurance, and a "stadium" or "cones" obstacle course.
Draft horse showing: Most draft horse performance competition is done in harness. Draft horses compete in both single and multiple hitches, judged on manners and performance.
