What happens when a swimmer goes before the signal?
B · Beginner · The stroke · 4 of 6A swimmer who starts before the signal may be disqualified, and there is no second chance. If the signal has already gone, the race carries on and the swimmer is disqualified at the end. If it has not, the others are told "stand down please" and the start is taken again without the offender.
How it works
- The rule: "Any Athlete who initiates a start before the signal may be disqualified."
- Signal already given: "the race will continue and the Athlete will be disqualified at the completion of the race".
- Signal not yet given: the signal is held back, the remaining athletes are stood down with "stand down please", and the referee repeats the procedure from the long whistle.
- Two officials: the referee disqualifies for an early start "if the initiation was observed and confirmed by both the Starter and the Referee".
- Video: where automatic officiating equipment is available, the referee reviews the footage to verify the disqualification.
- An unfair start: if the starter decides a start was not fair, the athletes are recalled and the race is started again.
- Other misconduct at the start: delaying the start or disobeying the starter is reported to the referee, who may disqualify.
This is the false start of the glossary.
Tricky cases
A swimmer flinches on the platform and then holds still. Is that a false start?
It depends on what the officials saw. The offence is initiating a start before the signal, and both the starter and the referee must have observed it.
A swimmer goes early and the race is allowed to run. Did they get away with it?
No. When the signal has already been given the race continues, and the swimmer is disqualified when it ends.
After a false start, do the other swimmers get a warning?
No. They are stood down and the start is repeated. Nobody else is penalised.
A swimmer falls in before "take your marks" because they slipped. Is that a false start?
No, not by itself. A false start is initiating the start before the signal. The starter and referee decide what happened.
Why the rule exists
Swimming once allowed a first false start to the field. That invited gamesmanship and long delays. One start for everyone removes both. Requiring the starter and the referee both to have seen it protects a swimmer from being put out on one person's impression.
