The semicircle under the basket in basketball is known as the restricted area. It was introduced to prevent defenders from drawing offensive fouls and causing collisions with players driving to the basket. The restricted area is a 4-foot arc that extends from the center of the basket to the front edge of the backboard on both sides of the hoop. It is an important addition to the basketball court, helping to enhance player safety and fairness during the game.

|---|---|
| Purpose | To enhance player safety by limiting collisions between offensive and defensive players under the basket |
| Application | The restricted area goes to the ceiling, meaning that even if a player has his back heel off the ground, if it is still over the restricted area, that player is still considered to be in the restricted area |
| Primary defender | Can legally draw a charge inside the restricted area against the player they are guarding |
| Secondary defender | Cannot legally draw a charge inside the restricted area |
| Secondary defender contact | A secondary defender can make contact with the offensive player inside the restricted area without being whistled for a foul if they follow the principle of verticality, being completely vertical and staying squared up to the offensive player |
| Restricted area extension | The restricted area does not extend to the baseline. The arc ends at the front edge of the backboard, so there is an area along the baseline that is not considered to be inside the restricted area |

What You'll Learn
The restricted area's purpose
The restricted area in basketball is a semi-circular arc painted just under the basketball goal. It serves two primary purposes: preventing injuries and ensuring fair play.
Firstly, the restricted area helps prevent injuries to airborne players. Before the implementation of the restricted area arc, secondary defenders could slide under offensive players who were about to jump, making it nearly impossible for the offensive players to avoid a collision. This sliding in late under a leaping offensive player can cause nasty falls.
Secondly, the restricted area provides penetrating offensive players with a fair opportunity to jump and land in the scoring area. It prevents secondary defenders from gaining an unfair advantage by shifting under a player who beat their primary defender and jumped to score.
In addition, the restricted area makes it easier for referees to call charges. Referees are tasked with making one of the toughest calls in sports – the split-second block-charge. The restricted area gives them another tool to make these difficult calls.
The restricted area goes to the ceiling, meaning that even if a player has their back heel off the ground, they are still considered to be in the restricted area. It is important to note that the restricted area applies to the secondary defender, not a primary on-ball defender. A primary defender (the person guarding the ball) can legally draw a charge inside the restricted area against the player they are guarding. However, a secondary defender attempting to draw a charge inside the restricted area will automatically be called for a blocking foul.

How it enhances player safety
The semicircle under the basket in basketball is called the restricted area. It is a recent addition to the basketball court, introduced to enhance player safety and make the game more uniform across different levels. Here's how the restricted area enhances player safety:
Reducing Collisions and Preventing Injuries: The restricted area is designed to reduce collisions between offensive and defensive players under the basket. Before the introduction of the restricted area, secondary defenders could slide under leaping offensive players, leading to nasty falls and potential injuries. By restricting defenders from taking charges within this area, the risk of such collisions and subsequent injuries is significantly reduced.
Fair Opportunity for Offensive Players: The restricted area gives penetrating offensive players a fair opportunity to jump and land in the scoring area without worrying about defenders sliding under them. This prevents defenders from gaining an unfair advantage and allows offensive players the necessary space to make their moves without fear of collision.
Clear Rules for Charges and Fouls: The restricted area provides clear guidelines for charges and fouls. Any secondary defender attempting to draw a charge inside the restricted area will automatically be called for a blocking foul. This clarity helps players understand their boundaries and reduces confusion during gameplay.
Encouraging Strategic Play: By teaching players to avoid the restricted area, coaches can encourage strategic offensive and defensive plays. Offensive players can drive confidently toward the basket, knowing that any contact from a secondary defender within the restricted area will result in a foul. Defensive players, on the other hand, can focus on getting into good defensive positions outside the restricted area and anticipating offensive moves.
Reducing Low-Post Collision Rate: The implementation of the restricted area has helped lower the low-post collision rate. This not only enhances player safety but also opens up the game, allowing for more dynamic and strategic plays.
In summary, the restricted area under the basket in basketball enhances player safety by reducing collisions, preventing injuries, providing fair opportunities for offensive players, establishing clear rules for charges and fouls, encouraging strategic play, and lowering the overall collision rate. These rules are designed to protect players, ensure fair play, and improve the overall flow of the game.

Its impact on the game
The half-circle under the basket in basketball is known as the restricted area. It is a recent addition to the basketball court, first appearing in the NBA during the 1997-98 season. This semi-circular arc extends 4 feet out from the center of the basket on both sides of the hoop.
The restricted area has had a significant impact on the game of basketball, primarily by enhancing player safety and reducing collisions under the basket. Before the introduction of the restricted area, defenders could slide under offensive players jumping to score, leading to dangerous falls and collisions. The restricted area now prevents this by providing a clear boundary that restricts defenders from taking charges within this area. This rule gives offensive players more space to jump and land, reducing the risk of injury and creating a fairer playing field.
The restricted area also affects the strategies employed by both offensive and defensive players. Offensive players can drive to the basket with more confidence, knowing that they will at least get to the free-throw line if there is any contact from a defender. On the other hand, defenders must be cautious not to position themselves inside the restricted area, as this will result in a blocking foul if they attempt to draw a charge. Coaches need to instruct their players on how to use the restricted area to their advantage, both when attacking and defending.
Additionally, the restricted area has helped to standardize the rules of basketball across different levels of the game. Previously, there were different sets of rules for various levels, creating confusion for players and coaches. The introduction of the restricted area has been a step towards making the game more uniform, with a consistent set of rules from top to bottom.
Overall, the implementation of the restricted area under the basket has improved player safety, reduced confusion around charging calls, and standardized the rules of basketball. It has also influenced the strategies used by players and coaches, affecting both offensive and defensive approaches to the game.

Rules for primary and secondary defenders
The half-circle under the basket in basketball is known as the restricted area. It is a semi-circular arc located under the basketball hoop, extending four feet out from the basket's centre. This area was introduced to address safety concerns and reduce excessive collisions under the basket.
Now, here are the rules for primary and secondary defenders regarding the restricted area:
- Primary Defenders: The player originally guarding the offensive player with the ball (known as the primary defender) can draw a charge near the basket, even inside the restricted area. This is allowed to give the defence a chance to recover if the primary defender is beaten by the dribbler.
- Secondary Defenders: A secondary defender cannot be in a legal guarding position inside the restricted area. If they are inside this area and make contact with the offensive player, it will be called as a blocking foul on the defender. However, there is an exception. If the offensive player receives the ball inside the lower defensive box (the area from the bottom tip of the free throw circle to the baseline), then a secondary defender can establish a legal guarding position inside the restricted area.
- Drawing Charges: Secondary defenders attempting to draw a charge inside the restricted area will automatically be called for a blocking foul. This rule encourages better defensive footwork and positioning, anticipating drives and trying to get in position outside the restricted area.
- Contact inside the Restricted Area: Not all contact inside the restricted area results in an automatic foul. A secondary defender can make contact with the offensive player inside the restricted area without being penalised if they follow the principle of verticality. This means maintaining a completely vertical position, staying squared up to the offensive player with arms straight up.
- Restricted Area Limitations: It is important to note that the restricted area does not extend to the baseline. It ends at the front edge of the backboard, so there is an area along the baseline that is not considered inside the restricted area. On a baseline drive, a secondary defender can draw a charge if the drive occurs between the backboard and the baseline.
- Offensive Strategies: Offensive players driving to the basket should be aware of defenders in the restricted area. If contact occurs, it will likely result in a foul called in favour of the offensive player, leading to potential free throws and scoring opportunities.
- Defensive Strategies: Defenders should avoid lingering inside the restricted area and focus on getting into good defensive positions early. By anticipating drives and positioning outside the restricted area, defenders can draw charges more effectively and avoid unnecessary fouls.
Understanding and adhering to these rules regarding the restricted area will help both primary and secondary defenders play effectively and safely, reducing collisions and creating a fair contest between offensive and defensive players.

The restricted area's history
The restricted area in basketball, also known as the "no-charge semicircle", is a semi-circular arc under the rim of the basket. Its primary purpose is to enhance player safety by limiting collisions between offensive and defensive players under the basket. The restricted area was created to protect offensive players who pressure defenders with speed and aggression to get into a better scoring position.
The restricted area was first instituted in the NBA during the 1997-98 season. It was added for two main reasons. Firstly, to prevent injuries to airborne players. Before the arc was added, secondary defenders would step in to draw a charge on players who were about to take off, making a collision inevitable. The restricted area makes it much less beneficial for secondary defenders to attempt to take a charge too close to the basket, as they will automatically be called for a blocking foul. Secondly, the addition of the restricted area helps officials to make the block/charge call. While this call is usually a judgement call, the restricted area takes all judgement out of it, at least near the rim.
The dimensions of the restricted area vary depending on the type of league or competition. In the NCAA, the restricted area arc measures three feet out in every direction from the basket. In the 2015-16 season, the NCAA moved the RA arc out to four feet from the centre of the basket. In the NBA, the restricted area measures four feet out in every direction from the basket.
The restricted area is very clearly marked with an arc to help players, coaches, and referees. Driving players need to recognise when a defender is stationed in the restricted area. This should allow players to drive confidently to the basket, knowing that they will at least go to the free-throw line if there is any contact on the drive.
