Basketball referees, also known as officials, are responsible for ensuring that a basketball game is played fairly and safely. They are in charge of calling fouls, violations, and time-outs, as well as managing the game clock and ensuring that the court and equipment are in proper condition. Referees use a variety of hand signals to communicate their calls to players, coaches, and spectators. These signals include an open hand in the air to indicate a violation, a closed hand for a foul, and three fingers pointed down at their side for a 3-second violation. Referees also have the power to eject fans from the arena if necessary.

What You'll Learn
Referee signals for fouls
Basketball referees have a variety of signals to communicate calls during a game. When a foul occurs, the referee will first blow their whistle and put a closed hand in the air. This closed-hand signal differentiates fouls from violations, which are indicated by an open hand. After the initial signal, the referee will indicate the type of foul committed.
A blocking foul occurs when a defensive player does not have a legal guarding position and impedes the progress of the dribbler. The referee signals this by placing both hands on their hips. Conversely, if the defensive player is in a legal guarding position and the offensive player knocks them off their spot, a charging foul is called.
A hand-checking foul is called when a defender limits the offensive player's movement with their hands. The referee will signal this by chopping one hand across the opposite wrist. Holding fouls are indicated when a player grabs another player by the jersey or any body part. The referee will make a fist with one hand, hold that arm out, and then mimic grabbing their wrist with the other hand.
Pushing fouls are signalled by extending both arms and making a pushing motion with the hands. An intentional foul, resulting in two shots for the offensive team and possession of the ball, is signalled by raising both arms and forming an 'X'. A technical foul, called for unsportsmanlike behaviour, is signalled by forming a 'T' with both hands.

Referee signals for violations
Basketball referees have a variety of signals to communicate calls during a game. When a violation occurs, a referee will blow their whistle and raise an open hand to signal a dead ball. They will then use specific gestures to indicate the type of violation.
For example, a carrying violation is called when a player is dribbling and places their hand under the ball before continuing to dribble. To signal this, the referee flips their hand over from palm up to palm down several times. A traveling violation, on the other hand, is called when a player illegally moves their feet. The referee will signal this by putting both arms in front of their face and moving them in a circular motion.
Another common violation is a double dribble, which occurs when a player dribbles, picks up the ball, and then dribbles again. The referee will signal this by placing their hands in front of them with palms down, then alternating between moving their hands up and down. A 3-second violation is called when a player remains in the paint, the area closest to the basket, for more than 3 seconds. The referee will indicate this by holding up three fingers and swiping their hand back and forth.
Additionally, there are signals for time-related violations. A 5-second violation is called when a team takes too long to throw the ball inbounds, and the referee will signal this by holding up five fingers. If a team in the front court goes into the backcourt without the defense touching the ball, an over-and-back violation occurs. The referee will signal this by placing their hand out with the palm down and moving it back and forth, indicating that a player crossed the half-court line. For a 24-second violation, where a team fails to shoot within the allotted time, the referee will tap the top of their shoulder on the same arm.

Referee signals for time-outs
Basketball is a sport that involves a lot of referee signals to indicate violations, fouls, and other aspects of the game. One of the most important signals is the one for a time-out, which can be called by either the players or the referee.
When a player or coach calls for a time-out, they typically make a “T” symbol with their hands. This is not a requirement, but it helps to quickly convey the message to the referee. The referee then confirms the time-out by touching both shoulders or sticking both arms straight out to the side with fists clenched. This full timeout signal is distinct from other signals, such as the one for a three-point shot, where the referee raises one arm straight up in the air.
It is important to note that the referee's time-out signal can be confused with the "Tech" gesture, which is a traditional signal for a technical foul. To avoid this confusion, referees should use the shoulder tap or the full timeout signal with arms outstretched and fists clenched.
Additionally, when a violation occurs, the referee will blow their whistle and raise an open hand in the air before specifying the type of violation. For example, a traveling violation is signaled by the referee putting both arms in front of their face and moving them in a circle. On the other hand, when a foul occurs, the referee will blow the whistle and raise a closed hand in the air, indicating that a foul has been called.
Understanding these referee signals is crucial for players, coaches, and fans to follow the game and ensure fair play. The signals help convey information quickly and effectively, contributing to the smooth flow of the game.

Referee equipment checks
Referees in basketball have a duty of care to the players, and must ensure that the court and all equipment are in a safe and usable condition. They are required to inspect and approve all equipment before the game, including the court, baskets, balls, backboards, timers, and scorers' equipment.
One of the key checks is for the basketballs, which need to be properly inflated. Referees also need to ensure that players are not wearing any equipment that could be dangerous to other players. For example, any hard substances like casts, splints, guards, and braces must be padded or foam-covered, and must not have any exposed sharp or cutting edges.
Face masks and eye or nose protectors are permitted, but they must be approved by NBA Basketball Operations, fit the contour of the face, and have no sharp or protruding edges. Referees must also ensure that no player is wearing any jewelry.
At higher levels of college and professional basketball, officials also wear a timing device on their belt called a Precision Timing System (PTS). This allows them to start and stop the game clock without waiting for the scoreboard operator, helping to ensure the smooth running of the game.

Referee positioning
Basketball referees have a challenging job, as they must be aware of what is happening around the ball and the roughness of play across the whole court. They must also manage players and spectators, and ensure that the court and equipment are in a safe and usable condition.
Referees' positioning is crucial to their ability to make accurate calls. The lead referee takes up a position on the sideline, level with the top of the three-point line. The second referee is the "trail" official, positioned on the same sideline as the lead referee but level with the free-throw line. The third referee stands across the court near the free-throw line in what is called the center position. This creates a triangle coverage of the court. The lead referee may switch sides of the baseline during play, requiring the trail and center referees to switch positions. As the ball moves to the other end of the court, the lead becomes the trail, the trail becomes the lead, and the center official remains in the center.
The positioning of referees is not just important for making accurate calls, but also for effective communication with players, coaches, and other officials. They must also be aware of the proximity of the crowd, as well as coaches and players on the bench, and have the authority to remove a disruptive fan from the arena if necessary.
Research has shown that the visual search behavior of basketball referees varies with their court position and experience. Eye-tracking studies have found that experienced referees exhibit lower total fixation times than novice referees, and that referees in the trail position tend to have more fixations of shorter duration and a greater focus on the basket than those in the lead position.

Frequently asked questions
Basketball referees, also known as officials, are responsible for ensuring that the game is played safely and fairly. This includes calling the game, managing players and spectators, and inspecting and approving equipment before the game. They also need to be aware of the roughness of play on the court and can remove fans from the arena if necessary.
Basketball referees call fouls, violations, and time-related issues. A foul occurs when a player makes illegal physical contact with another player while the ball is in play. A violation, on the other hand, refers to actions that break a basketball rule, such as travelling or stepping on the line. Referees also call time violations, such as a 24-second violation if a team fails to shoot within the allotted time.
Basketball referees use specific hand signals to indicate their calls. For example, a closed hand in the air indicates a foul, while an open hand signals a violation. To indicate a 24-second violation, a referee will tap the top of their shoulder on the same arm. For a 3-second violation, they will swipe three fingers down at their side back and forth.
