If you’ve ever watched a swimmer touch the wall first, only to see “DQ” show up next to their name on the results sheet, you know how confusing and frustrating it can feel. DQ stands for disqualified, and in swimming it means the swim didn’t count — no matter how fast it was.
This guide breaks down exactly what DQ means, the most common reasons swimmers get disqualified in each stroke, how the process works on deck, and practical ways to avoid getting caught out by the rules.
Quick Answer
DQ means “disqualified.” In swimming, a swimmer or relay team is disqualified when they break a technical rule for the start, stroke, turn, or finish of a race. A DQ removes the swim entirely from results — it won’t count for place, points, awards, or a qualifying time, even if it was a lifetime-best swim.
How a DQ Actually Happens on Deck
Certified officials watch every swimmer during a race: a starter oversees the start, stroke-and-turn judges walk the pool deck watching strokes and turns, and turn judges are positioned at the walls. If an official sees a clear rule violation, they raise a hand and submit a written report to the referee, who has final authority to confirm the disqualification.
In relays, a separate takeoff judge watches the feet of the swimmer on the blocks and the touch of the incoming swimmer at the same time. If the departing swimmer’s feet leave the block before their teammate touches the wall, that’s an early takeoff and the whole relay team can be disqualified — even if only one swimmer made the mistake.
After the meet session, the swimmer or their coach can typically look at (or ask to see) the written DQ slip, which states the exact rule and often the specific stroke cycle or turn where the infraction happened. This is the best way to learn what actually went wrong instead of guessing.
The Most Common DQ Reasons, By Stroke
False start: In individual events, any forward movement after “take your mark” before the starting signal is an automatic disqualification — there’s no warning or second chance. For relays, an early takeoff (see above) is the equivalent violation.
Freestyle: The most common freestyle DQs are not touching the wall at the finish (or on a turn if the event requires it), pulling on the lane lines to gain an advantage, or pushing off the bottom of the pool.
Backstroke: Swimmers are disqualified for rotating past vertical toward the breast at any point except during the continuous motion of a turn, or for leaving the wall on their front after a turn. Standing on the bottom during a backstroke race is also illegal.
Breaststroke: This is the most technical stroke to judge. Common DQs include a touch where the hands aren’t separated and simultaneous at the wall (the hands don’t need to be level with each other — they can touch at, above, or below the water surface — but they must arrive at the same instant and can’t be stacked on top of each other), a kick that isn’t a simultaneous, symmetrical breaststroke kick (a “scissor” or flutter kick sneaking in), more than one arm stroke and one leg kick while fully submerged off the start or turn, and the head not breaking the surface within the required stroke cycle.
Butterfly: Typical violations are a finish or turn touch where both hands don’t arrive separated and simultaneously, alternating (rather than simultaneous) arm recovery, and a non-simultaneous, non-symmetrical kick.
Underwater distance limit: In freestyle, backstroke, and butterfly, part of the swimmer’s body must break the surface of the water by the 15-meter mark off every start and turn. Staying underwater past that point is a DQ. This 15-meter rule does not apply to breaststroke, which instead has its own strict rule limiting the pullout to one arm stroke and one kick before the head surfaces.
Tips to Avoid Getting Disqualified
Drill your turns and finishes in practice at race pace, not just at an easy warm-up speed — most DQs happen when a tired swimmer’s technique breaks down at the wall, not in the middle of the pool.
For breaststroke and butterfly, have a coach or teammate watch your touches from the side to confirm both hands arrive separated and at the same time — they don’t have to be level with each other, but a touch where one hand clearly lands before the other, or where the hands overlap instead of separating, is a DQ.
On starts, stay still and relaxed once you’re set — anticipating the buzzer is the number one cause of false starts.
In relays, the departing swimmer should watch the incoming swimmer’s hand touch the wall (not just judge it by feel or sound) before leaving the blocks, and keep at least part of a foot in contact with the block until that touch happens.
If you do get DQ’d, ask to see the official’s written slip. It names the exact rule broken, which turns a confusing result into a specific, fixable technique cue for your next practice.

Swimming disqualifications (DQ) FAQs
Does a DQ count as a false start against the whole meet?
No. Modern USA Swimming rules disqualify only the individual swimmer (or relay team) responsible — there’s no longer a rule where one false start eliminates an entire heat or field.
Can a DQ’d time still be used for a best time or qualifying standard?
No. A disqualified swim is removed from the results entirely, so it cannot count as an official time, a personal best, or a qualifying time for another meet, even if the clock showed a fast result.
Who decides a disqualification, and can it be appealed?
Certified stroke-and-turn judges, turn judges, and the starter report violations to the meet referee, who has final authority to uphold a DQ. Many meets allow a coach to formally question or appeal a call to the referee, but the specific process varies by meet and governing organization.
Do breaststroke and butterfly touches have to be at the same hand level?
No. USA Swimming rules require the touch to be made with both hands separated and simultaneously — at the same instant — at, above, or below the water surface. The hands don’t need to be level with each other, as long as they touch the wall together rather than one before the other.
Is a DQ the swimmer’s fault if a relay teammate causes it?
Not necessarily for that individual’s own technique — but an early relay takeoff by any one swimmer disqualifies the entire team’s result, since relay rules apply to the exchange between teammates, not just individual strokes.
