Basketball is a sport that involves a lot of hand signals, from referees signalling fouls and violations to players and crowds signalling their support for a three-point shot. The hand signals used in basketball can vary depending on the region and the specific violation that occurred. For example, referees will point at their foot to signal a kick, use a chopping motion with their hand to signal a holding foul, and point with their hands to signal whose ball it is after it goes out of bounds. Players and crowds also use hand signals, such as extending three fingers to signal support for a three-point shot.

Referee signals for fouls and violations
Basketball is a game full of quick movements, and it can sometimes be hard to keep track of what is happening. Referee signals are an important part of the game, indicating violations, fouls, and other aspects of the game. Here is a guide to some of the most common referee signals for fouls and violations:
Fouls
A foul is when a player commits an infraction or a breach of the rules. When a foul occurs, the referee will first blow their whistle and place a closed hand in the air. The referee will then indicate the type of foul:
- Holding Foul: A Holding Foul occurs when a defender grabs an offensive player. The referee will make a fist with one hand, hold that arm out, and then "grab" their wrist with the other hand.
- Pushing Foul: A Pushing Foul occurs when a defender pushes or bumps into an offensive player. The referee will put both arms out and make a pushing motion with their hands.
- Blocking Foul: A Blocking Foul occurs when a defender uses their body to make contact with an offensive player with the ball. The referee's signal for blocking is placing both hands on their hips.
- Charging Foul: A Charging Foul occurs when an offensive player runs into a defensive player who already has a legal guarding position. The referee will indicate this by forming a T with their arms.
- Hand-Checking Foul: This foul occurs when a defender limits the movement of an offensive player with their hands. The referee will chop one hand across the opposite wrist.
Violations
A violation is when a player breaks a rule, such as travelling or stepping on the line. Some common violation signals include:
- Carry: When a player is dribbling and puts their hand under the ball, a carry is called. The referee will flip their hand over from palm up to palm down several times.
- 3-Second Violation: Players are only allowed 3 seconds in the paint. The referee will indicate this violation by pointing 3 fingers down at their side and then swiping their hand back and forth.
- 5-Second Violation: When a team takes longer than 5 seconds to throw the ball inbounds, the referee will indicate this by putting 5 fingers in the air.
- Over-and-Back Violation: When a player with the ball goes into the backcourt without the defense touching it, the referee will place their hand out with their palm down and move it back and forth, as if going over a line.
- Out of Bounds: When the ball goes out of bounds, the referee will indicate whose ball it is by pointing toward the basket of the team that will take possession.

Holding fouls
In basketball, contact between players often results in fouls, but the fast pace of the game also means that unintentional or incidental contact is common. The game's rules have been developed to maintain safety, and referees must judge whether contact is incidental or a foul. A personal foul involves illegal contact between players, including various contact fouls such as pushing, holding, blocking, tripping, or any other contact that inhibits an opponent's freedom of movement.
The concept of fouls has been part of basketball since its inception. James Naismith's original 13 rules from 1891-1892 included holding as one of the first five fouls, along with shouldering, tripping, pushing, and striking. Over time, the rules have evolved, and today, holding fouls are penalized based on the specific circumstances and the league's regulations.

Over-and-back violations
To signal a three-point shot in basketball, the player or the crowd will typically extend three fingers. This is shown in the film Inglourious Bastards, where a character indicates three using their index, middle, and ring fingers, with the thumb touching the pinky.
An over-and-back violation, also known as a backcourt violation, occurs when a team in possession of the basketball in the frontcourt returns to the backcourt without the defence touching the ball. For a violation to be called, the player must have established their position in the front court, which means both feet and the ball must be over the half-court line. Once this position has been established, the player cannot go back over the line with the ball, and the line becomes an out-of-bounds line.
A backcourt violation can occur in two ways: first, if the team fails to advance the ball from the backcourt to the front court within 10 seconds of taking possession; second, if the ball is dribbled or passed into the backcourt after the offense has possessed it in the front court.
It is important to note that a player can have one foot in the front court and one foot in the backcourt while dribbling, and this is not considered a violation. However, once both feet and the ball are in the front court, the ball must remain there.
The penalty for a backcourt violation is a dead-ball turnover by the offense, with possession being granted to the defence on the sideline near where the call was made.

Shooting fouls
In basketball, referees use a variety of signals to indicate violations, fouls, and other aspects of the game.
There are a few nuances to this. For example, if a player is fouled during a 3-point shot and makes the basket, it counts, and they are awarded one free throw. However, if a player is fouled during a layup or dunk, where there is more contact with the defender, it may not always be called a foul. This inconsistency can be frustrating for players and fans.
Additionally, each team is allowed a certain number of shooting and non-shooting fouls before the other team is permitted to shoot free throws. The number of fouls allowed varies between leagues. For example, the NCAA allows six team fouls before the opposition can shoot free throws, while the NBA only allows four.
Beyond shooting fouls, there are also non-shooting fouls, which occur when a player is not in the act of shooting. Common examples include reach-in fouls and blocking fouls. There are also technical fouls, which can be called on players or coaches for unsportsmanlike conduct, such as abusive behavior towards officials or excessively hard fouls.
Referees use specific hand signals to communicate these fouls and other violations to players, coaches, and spectators. For instance, a carrying violation is signaled by flipping the hand over from palm up to palm down several times. A three-second violation is signaled by pointing three fingers down at the side and then swiping the hand back and forth. A kick is signaled by pointing to the foot, and an out-of-bounds call is made by pointing toward the basket of the team taking possession.

Non-shooting fouls
Basketball is a fast-paced game, and contact between players is common. While the rules have been developed to keep the game safe, not all contact is deemed a foul. If a referee judges that contact between players is incidental, this will not be deemed a foul.
A non-shooting foul is a defensive foul, which is not in the act of shooting. If an offensive player does not gather the ball, nor start an upward shooting motion, nor continue that motion prior to a defender’s illegal contact, then this will be deemed a non-shooting foul.
There are several types of non-shooting fouls. Holding fouls are called when a player grabs another player by the jersey or any other body part. The referee will signal this by making a fist with one hand, holding that arm out, and then mimicking grabbing the wrist with their other hand. Pushing fouls are also common, and referees will signal these by putting two arms out and making a pushing motion with their hands. If a player connects with an opponent's elbow, this will also be deemed a foul, and if it is deemed flagrant, can result in two shots and possession of the ball for the team that was fouled.
Once a team reaches a certain threshold of fouls, they are deemed to be in the bonus. Any non-shooting foul they commit from that point on will result in at least a 1-and-1 free-throw opportunity for the other team, or two free throws in the NBA/WNBA. In non-professional leagues, a second threshold of fouls is called the double bonus, and when a team reaches this, their opponents are awarded two free-throw opportunities on non-shooting fouls.
