Behind the Vertical

A horse is behind the vertical (BTV) when its nose line falls behind an imaginary vertical line dropped from its forehead: the profile tips toward the chest. The FEI’s standard points the other way: a horse correctly “on the bit” carries the poll as the highest point of the neck and the nose, as a rule, slightly in front of the vertical. Behind the vertical is therefore a contact fault by definition, the most discussed one in modern dressage, and the centre of the sport’s longest-running welfare debate.

The standard and the fault

The FEI’s description of the correct connection is precise: a light, consistent, soft contact, a quiet mouth, the poll the highest point, the nose line at or slightly in front of the vertical. Every departure toward the chest moves the horse away from that standard, but the departures differ in kind, and judges and trainers distinguish them:

Momentary BTV, a few strides behind the vertical in a downward transition or a young horse ducking briefly against a half-halt, is ordinary training reality at every level, marked (if at all) within the movement concerned; the same tolerance appears across the common fault families.

Habitual BTV, a horse travelling behind the vertical as its default frame, is a genuine connection fault. The picture typically comes with a broken neck line, in which the highest point sits behind the poll partway down the neck, and the two together tell one story: the horse is not seeking the contact forward but curling away from it.

Hyperflexion is the extreme: the nose drawn markedly toward the chest, the neck deeply rolled. This is the territory of the rollkur debate, treated below.

The mechanics explain why the fault matters beyond aesthetics. A horse behind the vertical cannot stretch to the bit, so the connection from hind leg over the back to the hand, the throughness the training scale builds toward, is interrupted at its last link, and the frame is being held rather than carried.

How judges mark it

The FEI Judging Manual instructs judges to penalise contact and mouth problems, and BTV falls squarely in the category. In practice the marking follows the severity ladder: momentary tipping costs little; a movement performed in a clearly closed frame is capped in the “fairly good” region at best regardless of its mechanics; and a test ridden habitually behind the vertical loses twice, in the movements and in the harmony or submission collectives, because the closed frame and the interrupted connection are visible in everything. Judges’ remarks name it directly: “behind the vertical,” “tight in the neck,” “not out to the bit.”

The persistent criticism, voiced within the sport by judges and classical trainers alike, is that competition marking has historically been more tolerant of BTV than the written standard implies, particularly where the movement mechanics remain spectacular. The criticism is part of the sport’s public record; so is the counter-position that momentary profile geometry matters less than the overall quality of the connection. The wiki records the debate without adjudicating it: the written standard is unambiguous, and its enforcement is a live discussion.

Hyperflexion, rollkur and LDR

The extreme end of the spectrum has formal regulatory history. Following years of controversy, an FEI round-table conference in 2010 redefined hyperflexion/rollkur as flexion of the horse’s neck achieved through aggressive force, and declared it unacceptable, while accepting the technique known as Low, Deep and Round (LDR), flexion achieved without undue force. The decision drew the line at force rather than at geometry, which satisfied neither side of the debate entirely and remains the operative distinction.

The enforcement lives in the warm-up, not the test. The FEI’s stewards’ guidance, expanded after the 2010 decision with illustrated head-and-neck positions, instructs stewards to intervene against aggressive riding, and limits sustained or fixed head-and-neck positions to periods of roughly ten minutes without change. Critics within the sport argue the wording leaves stewards wide discretion; the guidance’s defenders answer that force, not frame, is the abusive element and the one a steward can judge. Both positions are published and current.

Causes

Habitual BTV has a short list of standard causes, and the diagnosis matters because the repairs differ. Hands before legs: a connection ridden front-to-back, the frame shortened by the rein rather than closed by engagement from behind. Evasion of honest contact: some horses curl away from the bit as their preferred evasion, especially sensitive-mouthed ones, and stay behind the contact even on a light rein. Strength gaps: a horse asked for a carriage its back and hindquarters cannot yet sustain drops behind the vertical as the frame collapses inward. Installed frame: horses produced in a short frame carry it as their learned default, long after the original cause is gone. The last category is the expensive one, because retraining a horse to seek the contact forward takes months of patient, systematic work.

What BTV looks like on video

For anyone evaluating a horse on a screen, the profile line is one of the fastest reads available, with three checks that separate signal from noise. First, the default, not the moment: every horse tips behind occasionally, so the question is where the nose lives across the whole clip, especially in ordinary working paces where nothing is being asked. Second, the highest point: a poll carried below a bulge in the mid-neck is the structural signature of a curled frame and harder to stage than a single stride. Third, the stretch test: footage of the horse stretching forward and down on a light rein (the exercise appears in tests at every level precisely because it cannot be faked) answers the question directly, and its absence from a sales video is itself information. The full checklist sits alongside the other fault families in reading sales videos.
