Flag in sport

Mar 30, 2017

Because of their ease of signalling and identification, flags are often used in sports.

  • In association football, linesmen carry small flags along the touch lines. They use the flags to indicate to the referee potential infringements of the laws, or who is entitled to possession of the ball that has gone out of the field of play, or, most famously, raising the flag to indicate an offsideoffence. Officials called touch judges use flags for similar purposes in both codes of rugby.

  • In American and Canadian football, referees use penalty flags to indicate that a foul has been committed in game play. The phrase used for such an indication is flag on the play. The flag itself is a small, weighted handkerchief, tossed on the field at the approximate point of the infraction; the intent is usually to sort out the details after the current play from scrimmage has concluded. In American football, the flag is usually yellow; in Canadian football, it is usually orange. In the National Football League, coaches also use red challenge flags to indicate that they wish to contest a ruling on the field.

  • In yacht racing, flags are used to communicate information from the race committee boat to the racers. Different flags hoisted from the committee boat may communicate a false start, changes in the course, a cancelled race, or other important information. Racing boats themselves may also use flags to symbolize a protest or distress. The flags are often part of the nautical alphabetic system of International maritime signal flags, in which 26 different flags designate the 26 letters of the Latin alphabet.

  • In auto and motorcycle racing, racing flags are used to communicate with drivers. Most famously, a checkered flag of black and white squares indicates the end of the race, and victory for the leader. A yellow flag is used to indicate caution requiring slow speed and a red flag requires racers to stop immediately. A black flag is used to indicate penalties.

  • In addition, fans of almost all sports wave flags in the stands to indicate their support for the participants. Many sports teams have their own flags, and, in individual sports, fans will indicate their support for a player by waving the flag of his or her home country.

  • Capture the flag is a popular children's sport.

  • In Gaelic football and Hurling a green flag is used to indicate a goal while a white flag is used to indicate a point

  • In Australian rules football, the goal umpire will wave two flags to indicate a goal (worth six points) and a single flag to indicate a behind (worth one point).

  • For safety, dive flags indicate the locations of underwater scuba divers or that diving operations are being conducted in the vicinity.

  • In water sports such as Wakeboarding and Water-Skiing, an orange flag is held in between runs to indicate someone is in the water.

  • In golf, the hole is almost always marked with a flag. The flagpole is designed to fit centered within the base of the hole and is removable. Many courses will use colour-coded flags to determine a hole location at the front, middle or rear of the green. However colour-coded flags are not used in the professional tours. (A rare example of a golf course that does not use flags to mark the hole is the East Course of Merion Golf Club, which instead uses flagpoles topped by wicker baskets.)

  • Flag poles with flags of all shapes and sizes are used by marching bands, drum corps, and winter guard teams use flags as a method of visual enhancement in performances.
