In athletics, if you move as the gun sounds, you have considered having false started as the human brain cannot hear and process the noise of the starting gun in under 0.10 secondsPrevious Fact Next Fact
In sports, a false start is a movement by a participant before being signaled or otherwise permitted by the rules to start. Depending on the sport and the event, a false start can result in a penalty against the athlete's or team's field position, a warning that a subsequent false start will result in disqualification, or immediate disqualification of the athlete from further competition. Unlike an offside penalty, where the play is run as usual, the play after a false start penalty immediately becomes dead. This is done to prevent a defensive player reacting to a false start from hitting the quarterback while going through the snap count, which would make the quarterback more susceptible to injury. At the end of the 2005 NFL season, owners complained regarding false start penalties on players whose flinches have little effect upon the start of the play, such as wide receivers.
An athlete making a false start would be allowed another start and would only be disqualified after a second false start. Between 2003 and 2009, if there was a single false start, then the whole field would be warned, and the original offender would be allowed a second start. If anyone made a false start on the second start, then they would be disqualified. In motor sports that have a standing start, if there is a false start then the offender is subject to a time penalty and the race is normally not restarted.
