How do you train a horse to stand quietly at the halt in harness?

Standing quietly at the halt is one of the most practical and frequently tested skills in pleasure driving and one of the most commonly undertrained. The foundation is teaching the horse to stop from ground driving and remain motionless until asked to move again. Many horses learn to halt but immediately begin fidgeting, stepping forward, or anticipating the next cue. Rewarding stillness by pausing at the halt for progressively longer periods before asking for the next movement teaches the horse that standing is part of its job. In harness, the horse must also learn to accept the weight and balance of the vehicle while standing still, which feels different from halting under saddle. Practicing the halt while hitched, with a ground person present, builds confidence before asking the horse to stand without assistance. Judges in pleasure driving classes frequently ask the class to halt and stand, and horses that paw, shift weight repeatedly, swing their hindquarters, or break into a jig are penalized. A horse that halts squarely and stands quietly while the driver sits with still hands gives an immediate impression of quality training and reliable temperament, which can be the deciding factor in a competitive class.
