Basketball is a fast-paced sport with a lot of rules, so it's no surprise that referees use hand signals to communicate their decisions. These signals are used to inform players, coaches, officials, and spectators of calls made during a game. While there isn't an exact count of the number of hand signals used in basketball, they cover a wide range of scenarios, from starting and stopping the clock to indicating fouls, substitutions, and violations. Players and coaches must understand these signals to ensure they can respond appropriately and maintain the flow of the game.

What You'll Learn
Signalling fouls
A hand-checking foul occurs when a defender limits the movement of an offensive player with their hands. The referee will signal this by chopping one hand across the opposite wrist. A holding foul is called 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 "grab" the wrist with their other hand. When a player pushes their opponent, the referee will call a foul and signal it by putting both arms out and making a pushing motion with their hands. An elbow foul is similar, with the referee signalling by imitating the action with their elbow.
An intentional foul involves excessive or violent contact that could injure the fouled player. The referee signals this by raising both arms over their head and touching their wrists together or crossing their fists. A double foul is signalled by extending both arms horizontally at shoulder level with fists closed and pointing downward. A technical foul is a violation of certain rules of the game, usually involving unsportsmanlike actions. The referee will signal this by making a "T" shape with their hands, with the left hand vertical and the right hand horizontal.
Other foul signals include a blocking foul, where the referee puts both hands on their hips, and a charging foul, where the referee will place one hand on the back of their head and point in the opposite direction of play with the other hand.

Signalling violations
Basketball is a fast-paced game with a lot of rules and a lot of room for interpretation. Referees use hand signals to inform players, coaches, officials, and the crowd of their decisions. When a call is made, the referee will blow their whistle and then use their arms and hands to signal a call. It is vital that all players, coaches, and assistant coaches understand each of these hand signals before the team enters the court.
There are several types of violations in basketball, and referees have specific hand signals to indicate each one. When a violation occurs, you will always hear the referee 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 then 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 official will use one hand and flip it over from palm up to palm down several times. A player is only allowed 3 seconds in the paint, and if they exceed this limit, the referee will call a 3-second violation. The referee will take three fingers, point them down at their side, and then swipe their hand back and forth to signal this violation.
If a team is taking too long to throw the ball inbounds (longer than 5 seconds), the referee will call a 5-second violation. This is signalled by the referee putting five fingers in the air. When a team possesses the basketball in the front court, and a player with the ball goes into the backcourt without the defence touching it, an over-and-back violation occurs. The referee will signal this by placing their hand out with their palm down and moving it back and forth from side to side, as if their hand is going over a line.
In a league that uses a shot clock, teams will have 24 seconds to take a shot on each possession. If a team fails to shoot within this time, the referee will call a 24-second violation. The referee will use one hand to tap the top of their shoulder on the same arm.

Signalling substitutions
Referees use hand signals to inform players, coaches, officials, and the crowd about decisions made during a basketball game. When a referee wants to indicate a substitution, they make an "X" with their arms, forming an "X" in front of their chest. This signal is typically made at a dead ball, when the clock is stopped, and indicates that a substitution is about to take place.
Players can also use hand signals to communicate substitution requests directly to their coaches or the bench. One common signal used by players is raising a clenched fist to indicate they need a break or a substitution. This signal allows the player to communicate their need for a brief rest without interrupting the flow of the game.
In some cases, coaches may implement a "self-substitution" system, where players have the autonomy to decide when they need a substitution. This system empowers players to take responsibility for their own performance and energy management during the game.
Substitutions are an integral part of basketball strategy, allowing coaches to adjust the lineup based on various factors such as energy levels, team dynamics, and player development. Understanding the reasoning behind substitutions can help players see the bigger picture and appreciate the strategic decisions made by their coaches.

Signalling time-related calls
Starting and Stopping the Clock
One of the most fundamental time-related signals is to start and stop the game clock. To start the clock, the referee raises one hand above their head and then drops it directly toward the floor. Conversely, to stop the clock, the referee raises their hand and keeps it raised. This signal is particularly important for the timekeeper to recognise and act upon.
Stopping the Clock for a Foul
When a foul occurs, the referee will often need to stop the clock to allow time for addressing the situation. To signal this, the referee raises one clenched fist. This signal is accompanied by a whistle blow, alerting players and coaches that a foul has been called.
Jump Ball
In the event of a jump ball, the referee will stop the clock by placing both hands directly in front of their chest with thumbs pointing upward. They will then raise both hands together and blow the whistle to indicate the jump ball.
3-Second Violation
When a player remains in the paint, the area closest to the basket, for more than three seconds, a 3-second violation is called. The referee signals this by holding up three fingers and then swiping their hand back and forth.
5-Second Violation
If a team takes longer than five seconds to throw the ball inbounds, the referee calls a 5-second violation. This is signalled by the referee holding up one hand with five fingers in the air.
8-Second Violation
When a team has the ball in the backcourt, they are given eight seconds to move the ball across the half-court line. If they fail to do so, the referee calls an 8-second violation. The signal for this is the referee holding out one hand with the palm down and moving it back and forth from side to side, indicating crossing the half-court line.
24-Second Violation
In leagues with a shot clock, teams typically have 24 seconds to attempt a shot. If they fail to do so within this time, the referee calls a 24-second violation. The signal for this is tapping the top of the shoulder on the same arm with one hand.
These hand signals are essential for managing the flow of the game, ensuring that all participants and spectators are aware of the time-related calls being made by the referee.

Signalling bonus free throws
Understanding Bonus Free Throws
Bonus free throws, also known as penalty situations, occur when a team accumulates a certain number of fouls within a specified period. The specific number of fouls required to trigger the bonus varies depending on the league and level of play. For example, in the NBA, WNBA, and FIBA rules, a team is allowed four team fouls in a quarter without penalty. However, once a team commits its fifth foul in the same quarter, it triggers the penalty situation, resulting in bonus free throws for the opposing team.
Referees play a crucial role in signalling bonus free throws. Here are the key hand signals used by referees to indicate bonus free throws:
- Signalling a Foul: When a foul is called, the referee will typically blow the whistle and use hand signals to indicate the type of foul. For a regular foul, the referee raises their right arm, forming a fist, while blowing the whistle.
- Intentional Foul: To signal an intentional foul, the referee raises both hands above their head and crosses their fists.
- Double Foul: In the case of a double foul, where players from both teams commit simultaneous fouls, the referee extends both arms horizontally at shoulder level with closed fists pointing downward.
- Technical Foul: To indicate a technical foul, the referee forms a "T" with their hands, placing the left hand vertically and the right hand horizontally on top.
- Stopping and Starting the Clock: When necessary, the referee will signal to stop or start the clock. To stop the clock, the referee raises their right hand directly up and blows the whistle. To start the clock, the referee chops their hand down.
- Free Throw Attempts: During bonus free throws, the referee will indicate the number of free throw attempts allowed. For a "one-and-one" situation, the referee signals one free throw attempt. If the first free throw is made, the referee may signal a second attempt with another hand signal.
Variations in Rules
It is important to note that the rules regarding bonus free throws vary across different basketball leagues and organizations. For example, the NCAA, WNBA, and high school basketball have their own specific rules regarding the number of fouls required to trigger the bonus and the application of the bonus free throw rule. Additionally, in overtime periods, the foul counts are typically reset, and the penalty phase may start with a lower number of fouls compared to regulation periods.
In summary, signalling bonus free throws in basketball involves recognizing when a team has accumulated the requisite number of fouls to trigger the bonus. Referees use specific hand signals to indicate fouls, types of fouls, and the stopping and starting of the clock. Understanding these hand signals is essential for players, coaches, and officials to ensure fair play and effective communication during the game.
