Four Faults: What Just Went Wrong

A rail down, a stop at the wall, a second past time — the fault system is simple on the surface and ruthlessly precise in practice.

The fault system is the engine of show jumping, and it is deliberately blunt. Most of the decisions a judge makes resolve into a single number: four. A rail knocked from its cupsCupThe bracket holding a pole, shallow at the front so the rail rolls out. — four faults. A refusalrefusalhorse stops forward movement in front of a fence; four faults, where the horse stops or runs past a fence — four faults. That symmetry is not an accident. When the rules were modernised through the mid-twentieth century and gradually standardised under the Fédération Équestre Internationale, the governing body brought the two most common errors into alignment partly to remove any question about which type of mistake was "worse." Knocking a fence and stopping at one are, arithmetically, equals. Everything else in the fault table flows from that anchor.

The number that ends a round is the sum of all faults accumulated on course. In a class with twelve fences, a horse that knocks two rails and has no other errors finishes on eight faults. A horse that knocks one rail and has one refusal also finishes on eight. They tie, and the order within that grouping is then decided by time — the faster horse is ranked higher. Time does not replace faults; it is the tiebreaker within a fault score, which is why riders who have already collected four faults have no incentive to slow down but every incentive to avoid a second rail.1

What Each Fault Category Actually Means

Rails. When a pole or plank falls from a fence, the fault is assessed on knockdownknockdownrail displaced from its cups by horse contact, scoring four faults, not on how the fence ends up. If a horse clips a verticalVerticalA single plane of rails with no spread — a pure height and accuracy question. on the way up but the rail stays in its cups, no fault is called. If the same rail falls five seconds later as the horse lands, the judges use their judgment about whether the impact was the direct cause — in practice, any rail that falls while the horse is in the air over that fence, or clearly as a result of that jump, counts. The rails themselves sit in cups specifically engineered to release under a relatively light force; the fence is designed to come down so that horse and rider are not injured. That hardware matters: a deep cup holds a rail more securely and a shallow cup releases at lighter contact, which is why cup depth is one of the decisions a course designer thinks about carefully at each fence.

Faults are counted per fence, not per rail. A horse that hits a triple barTriple barAn ascending spread of three elements, the widest common obstacle. and sends all three poles to the ground is charged four faults, not twelve. Only one fence, one incident, one ruling.

Refusals and run-outs. A refusal occurs when a horse stops in front of a fence. A run-out occurs when the horse evades by passing around the side of the obstacle rather than jumping it. Both are four faults each. Following a refusal or run-out, the rider must re-present the horse and jump the fence correctly before proceeding; skipping it and completing the rest of the course would result in elimination rather than an accumulating fault score.

The moment of assessment for a refusal is the horse's loss of forward momentum toward the fence. A horse that chips in an extra stride and jumps from very close, even awkwardly, has not refused — it has merely jumped badly. The distinction matters because a poorly ridden but completed jump costs nothing, while the same fence refused costs four. This is one reason experienced riders sometimes allow a horse to struggle through an ugly jump rather than risk the horse stopping: the ugly jump is free, the stop is not.

Disobediences is the category that covers both refusals and run-outs under the rules. Three disobediences in a single round historically triggered elimination, a rule that was revised over time. Current FEI rules eliminate a horse after its second disobedience anywhere on the course, or — depending on the specific competition level — after a cumulative number in the round. The practical effect is that a horse cannot endlessly refuse and re-attempt; the rules are designed to limit the time a class can be held up and to recognise that a horse with persistent stopping problems should not continue.

Time faults. Every round is run against a time allowed, calculated from the course length and a specified speed. For each second over the time allowed, the horse incurs a single time fault. These accumulate without limit — in theory a horse could trot the course and finish on thirty-odd time faults — but in competitive practice they become significant when a round is otherwise clean. A horse that jumps a clear round but finishes one second over time scores one fault. That one time fault is often the difference between first place and fourth.

Time faults and jumping faults are added together for a single score. There is no weighting — a time fault and a jumping fault are both worth the same point in the final total, even though they arise very differently. This is occasionally counterintuitive to new spectators who feel a knocked rail is a more serious error than being a second slow, but the arithmetic does not make that distinction.

Elimination. Beyond faults lies elimination, which ends the round without a competitive score. Elimination is called for: jumping a fence in the wrong order, jumping a fence in the wrong direction, jumping a fence not on the course plan, a second refusal or run-out in the round, a fall of horse or rider, failing to cross the start line within the allotted time after the bell, and exceeding the time limit, which is typically set at double the time allowed. An eliminated horse exits with no placing for that round. In a class that runs over two rounds, elimination in the first round ends participation entirely.

A fall is always elimination, no exceptions. The rule is clear: if the horse's shoulder and haunch on the same side touch the ground simultaneously, it is a fall. If a rider's feet leave the stirrups and they separate from the horse, it is a fall. Remarkably timed saves — a rider who appears to be coming off but regains the saddle — are not falls if that threshold is not crossed.2

Clear, Zero, and the Vocabulary of a Result

A round with no jumping faults and no time faults is a "clear round" or, colloquially in some traditions, a "double clear" when it refers to both rounds of a two-phase competition. The posted score is zero. In many competition formats, a zero earns entry to a jump-off — the shortened second round that decides the placings among all those who finished level on zero. Where only a handful of combinations go clear in the first round, a jump-off can be two or three horses; at major championship level, ten or more clears are not unusual.

The fault table also produces some results that read identically on paper but arrived differently: four faults earned by a knockdown and four faults earned by a refusal are the same number, and rankings among horses on four faults are then sorted purely by time. This means a horse that stopped, re-presented, and then finished in a good time can outrank a horse that jumped a flowing round but knocked a late fence and drifted slightly over the time. The mathematics does not reward style, only accuracy and pace.

Why the System Works

The fault system's elegance is its resistance to ambiguity. Unlike sports scored by human aesthetic judgment, show jumping produces a number. Rail falls or it doesn't. Horse stops or it doesn't. Time runs or it doesn't. That numerical clarity is one reason the sport works at the Olympic Games and at a local show using the same rulebook: the outcome is always legible, regardless of who is watching or how much they know.

What the system demands of the combination is equally legible: jump every fence, jump them cleanly, and do it within the time. The compressed simplicity of that requirement contains an enormous range of difficulty depending on the height, the course design, and the horse. A rider who watches the scoreboard seeing "0" against every other combination feels the same pressure whether the fences are 1.20 metres or 1.60 metres. Four faults is four faults at every level, and a clear is always a clear.

Every figure in this guide is indicative. Heights, spreads, speeds and distances vary between levels and federations, and the rules of the competition being run always govern.
