There are 36 different hand signals for indicating touchdowns, safeties, penalties and other events on the field. The system was developed so the game statistician and the knowledgeable fans could understand what the issue was before the days of wireless communication between the Referee and the PA system.
A complete set of hand signals can be found by visiting the link in the 'Related Links' section.
The IFAB Laws of the Game, which are the rules by which the world plays the game of Association Football (also called Soccer), has an addendum that describes the mandatory signals that a referee must use to control the game.
When the ball goes out of bounds over the touch line (sideline), the referee will point his arm upward at a forty-five degree angle in the direction of the goal that the team getting possession is attacking. If an infraction causes the direction of the throw-in to change, some referees will tumble their hands similar to a "false start" signal in the NFL, but this signal is non-standard and not required; whether or not this "change" signal is given, the throw-in signal is then given in the new direction.
When a free kick is awarded, the referee will blow the whistle and make the same signal as a throw-in. If it is unclear to the players that the signal is for a free kick, or if the players are not placing the ball in the correct spot, the referee will point to the spot on the ground where the ball should be placed.If the free kick is an indirect one, then the referee will also raise his other hand over his head, and maintain that hand until the ball is kicked and moves and then touches another player or goes out of play. Some referees will also indicate the nature of the infraction using a gesture from the list of gestures that are not mandatory or standardized, below.
The referee can indicate that a restart is ceremonial (players must wait for the whistle) by conspicuously pointing to his whistle so that all players near the ball are aware of it. Note that all kick-off starts and restarts are automatically ceremonial, and so this gesture is not needed.
A goal kick is signaled by pointing laterally (not raised) at the goal defended by the team taking the kick. A corner kick is signaled by pointing upward toward the corner from which the kick shall be taken.
A penalty kick is indicated by the referee running to the penalty mark and pointing down at it. A kickoff is indicated by pointing in the direction of the center circle, such as after a goal is scored; this gesture is usually make with the palm up. The end of the game can also be signaled this way, but is often also called for by waving one or both arms above the head.
A referee will give permission for a player or team official to enter the field by waving them near or giving a thumbs-up to the assistant referee or fourth official in the vicinity.
A referee can signal applied advantage by extending both arms in the direction of play, as if to say "play on". The referee may still call the original foul if the anticipated advantage does not materialize within a few seconds.
At the end of the 45th minute of each half, the referee will use his fingers to indicate the number of additional minutes of play he has allotted. The referee may extend this time without further signals, but cannot end the period sooner without abandoning the match.
The referee may use other gestures to help control the game, though these are not mandatory or standardized, such as indicating the reason for a foul or backing up a wall forming in front of a free kick. Some such signals are listed below.
The referee may use other signals or variations of these to communicate fouls and other information. He may also develop secret signals for his assistant referees and fourth official to make things more efficient. Some leagues and competitions may also mandate other signals that the referee may or must give.
In American football referees use flags to indicate various penalties.
Unlike Rugby Soccer (football) has only a few hand signals. For a visual reference see related link
he points his hand at the try line and blows the whistle
The hand closest to the referee. Depending where you are and which way you are facing. This allows the referee to better hear and see the flag when you raise it. Good luck.
Hand signals are used by referee's to relay the information of what foul took place to the stat officials sitting at the scorer's table. Using hand signals, the referee's do not need to walk over to the table and tell exactly what foul occurred, instead they use hand signals to describe the foul and which player committed the foul.
The referee in Volleyball has the final say on out/in. They have 25 hand signals at the ready to make the most accurate decision when in a Volleyball game. There is the 1st Referee, 2nd Referee and the Linesmen which contribute to the decision whether it's in or out.
There are no cards......
As a referee myself i have spent many hours going over the hand signals and signs but the best place to start is by looking in the rule book. The rule book is on the FIBA internet site.
Holding up one, two or three fingers are hand signals for various things (e.g. three seconds in the key) used by the referee. Because of this, players are barred from using those numbers to avoid confusion when the referee signals a player's number.
5 structures can be: the soccer net the referee the players the soccer field and the soccer ball I hope it helped!
Soccer referees are graded by levels, not by classes. Informally, a referee might be considered "Class A" if they are certified International referees.
There is a dot net website called Soccer Referee Information or SOCREF. This site is intended to be a source for information for current and aspiring soccer referees.
The Referee scores the game.
