Hand signals for fouls
Hand signals are an important part of basketball, helping referees communicate with players, coaches, and officials during a game. They indicate when a foul has been committed, a timeout has been called, or when the ball is out of bounds.
Referees use hand signals to communicate fouls, violations, and clock operations. Signals include raising one hand to stop the clock, a clenched fist to indicate a foul, and rolling both arms to indicate traveling. When a foul occurs, the referee will first blow their whistle. To indicate a technical foul, the referee will make a T' shape with their hands. A double foul is signaled by the referee putting both hands out, in fists. For a hand-checking foul, the referee will chop one hand across the opposite wrist. A holding foul is signaled by making a fist with one hand, holding that arm out, and then grabbing the wrist with the other hand. Pushing is signaled by putting two arms out and making a pushing motion with the hands.
There are also signals for different types of fouls like charging, blocking, and intentional fouls. A reaching-in foul is not listed in the rulebook, but if contact is made, the referee can call a pushing or holding foul. A player is allowed to dribble the ball above their head, but the only restrictions are that the ball cannot come to rest, and the dribbler's hand must stay on top of the ball. Players are allowed to reach over the back of another player as long as no contact is made.

Signals for violations
Referees use hand signals to communicate fouls, violations, and clock operations during basketball games. When a violation occurs, the referee will blow their whistle and raise an open hand in the air before signalling the violation. The open hand in the air signals a dead ball. The referee then gives their signal, and the ball is taken out of bounds to resume play.
A carrying violation is called when a player is dribbling the basketball and puts their hand under it and then continues dribbling. To signal a carry, the referee will use one of their hands and flip it over from palm up to palm down several times.
A 3-second violation is called when a player is in the paint for more than 3 seconds. The referee will call this out and then take three fingers, point them down at their side, and then swipe their hand back and forth.
A 5-second violation occurs when a team takes longer than five seconds to throw the ball inbounds. The referee will call this out and then use one of their hands and put five fingers in the air.
An 8-second violation occurs when a team has the ball in the backcourt and fails to get it across the half-court line within 8 seconds. The referee will call this out and then put eight fingers in the air.
A 24-second violation occurs when a team fails to shoot within 24 seconds of possessing the basketball in the front court. The referee will call this out and then use one hand to tap the top of their shoulder on the same arm.
A double dribble violation occurs when a player dribbles the ball, picks it up, and then dribbles again. The referee will call this out and then put both of their hands in front of them with palms down, and then alternate moving them up and down.
A traveling violation occurs when a player illegally moves one or both of their feet. The referee will call this out and then put both arms in front of their face and move them in a circle.

Clock operations
Basketball referees use hand signals to communicate rulings on fouls, violations, and clock operations. These signals are a visual method for referees to notify coaches, players, and spectators about events, penalties, and the status of the game clock without interrupting play with verbal announcements.
To signal the start of the clock, the referee begins with one hand raised above their head, then drops the raised hand directly toward the floor. The clock starts when the referee's hand reaches the floor. The referee does not blow the whistle during this signal.
To stop the clock, the referee raises one hand and keeps it in the air. The timekeeper should stop the clock when they see this signal. The referee will also blow the whistle when stopping the clock.
When a referee wants to stop the clock for a foul, they will raise a clenched fist and blow the whistle.
When a team fails to shoot within the time limit, the referee will call a shot clock violation. The referee will tap the top of their shoulder with one hand to signal a 24-second violation.
When a player goes over the half-court line with the ball, the referee will place their hand out with the palm down and move it back and forth from side to side to signal an over-and-back violation.

Signals for substitutions
Basketball is a fast-paced game with numerous rules and a lot of back and forth between the two teams. To help referees communicate rulings, updates, and scores to other officials, players, and spectators, they use hand signals. These signals are also used to notify coaches, players, and spectators about events, penalties, and the status of the game clock without interrupting play with verbal announcements.
When it comes to substitutions, the process begins with the coach of the team requesting a substitution. This request is made to the referee, who then waits for the next dead ball to signal the substitution. To signal a substitution, the referee will make an "X" with their arms.
In basketball, there are a lot of dead balls where the clock is stopped. The clock doesn't start again until a player on the floor touches it. Instead of the timekeeper making a judgment of when to stop the clock, they wait for a signal from the referee. The referee will keep their hand in the air until it's time to start the clock again. Once the time has come, the referee will drop their arm, and the time will start.
It is important for referees, coaches, players, and fans to understand the various hand signals used in the game. These signals help ensure that everyone involved can follow what is happening on the court and make the right decisions accordingly.

Hand signals for scoring
Hand signals are used in basketball to communicate rulings on fouls, violations, and scoring plays. They help to convey information to other officials, players, and spectators during the fast-paced game.
Referee Signals for Scoring
Referees use specific gestures to indicate scoring plays, such as successful field goals or free throws. They also signal free throw attempts, timeouts, and substitutions. For example, when a player from both teams possesses the basketball, a jump ball is called. The referee will give two thumbs up above their head to signal this.
Player Signals for Scoring
Players also use hand signals to communicate certain plays to their teammates. For example, a player without the ball may slap their elbow to indicate that they want the ball in the high post, or they may point at the floor to signal that they want a screen from a teammate. These signals can vary from team to team, with some teams using numbered play calls that correspond to specific hand signals.
Signals for Fouls and Violations
In addition to scoring, referees use hand signals to indicate fouls and violations. For example, a closed hand in the air means that a foul has occurred, while an open hand signals a violation. After signalling a foul, the referee will indicate the type of foul, such as blocking or charging. Referees also use hand signals to indicate violations such as traveling (both arms moved in a circle in front of the face), double dribble (one hand flipped over from palm up to palm down), or 3 seconds in the paint (three fingers pointed down at the side and then swiped back and forth).
