Two free throws and the ball. Short of a flagrant, nothing a defender can do to an opponent on an NBA floor is priced higher, and the league charges it for a foul that can look entirely routine: a hand on a hip, a tug at a jersey, a reach across a forearm from one step behind. What turns that contact into a clear path foul is geography. Rule 12B, Section I of the NBA rulebook reserves the penalty for a defender who fouls an opponent on a fast break when nobody on his team is ahead of the play.
The rule sets three tests, and all three must be met. The foul has to be committed on an offensive player during his team's transition scoring opportunity. At the instant of the foul the ball must be past the tip of the circle in the backcourt, no defender may be ahead of the player with the chance to score, and that player must have the ball or have a pass to him already in the air. And the foul has to take the scoring chance away. Two exceptions cancel it: a foul on a player in the act of shooting, and a foul caused by a defender's attempt to intercept or deflect the pass.
What an NBA clear path foul is, and why it carries the stiffest ordinary penalty
The rulebook's own name for it is a "clear-path-to-the-basket foul," and it appears in the list of things a team is awarded for a personal foul, just after the shooting and penalty free throw provisions and just before an older provision about fast breaks. The award is "two free throw attempts and possession of the ball on the sideline nearest the spot where play was interrupted."
Set that beside what other fouls cost. A common foul before a team reaches its limit costs a throw-in. A common foul in the penalty costs two shots, and then the defense has a chance at the rebound. A shooting foul on a missed layup is the same. In each of those cases the defense has given up at most two points and gets the ball back, or a chance at it.
A clear path foul gives up two shots and then another possession on top. Nothing is rebounded. The offense walks from the line to the sideline and starts again.
The reasoning is plain. A player alone on a breakaway is about to score, by the most efficient shot in the sport. A defender who cannot catch him has one move left, which is to grab him before he gets there, and if that grab cost only a side-out it would be the correct play every time. The league wants the dunk. It set the penalty so that the foul is always worse for the defense than the basket would have been.

- 1Free throws for a transition take foul
Counts taken from Rule 4 and Rule 12B of the NBA rulebook. The single free throw is the penalty for the lesser transition take foul, shown for comparison.
Unlike a technical, it is a personal foul in every accounting sense. It goes on the defender's line and on the team's total. Unlike a flagrant, it says nothing about the defender's conduct. A clear path foul can be gentle. Officials are not asked whether the contact was hard or cynical, only where ten players were standing when it happened.
The three tests officials run on a clear path foul
Rule 12B sets the test out in three numbered clauses. First, a personal foul is committed on any offensive player during his team's transition scoring opportunity. Second, when the foul occurs, the ball is ahead of the tip of the circle in the backcourt, no defender is ahead of the offensive player with the scoring opportunity, and that player is in control of the ball or a pass to him has been released. Third, the defensive foul deprives the offensive team of a transition scoring opportunity.
The second test is really three position checks bundled together, which is why officials and broadcasters often describe the rule as a checklist of four or five items.
- Transition opportunityIs the offense continuously advancing the ball after a change of possession, with an advantage from speed, from the defenders' positions or both?
- Ball positionAt the moment of the foul, is the ball ahead of the tip of the free throw circle in the backcourt?
- No defender aheadIs every defender, the one committing the foul included, behind or beside the offensive player with the scoring chance?
- Ball or passDoes that player have control of the ball, or has a pass to him already left the passer's hands?
- DeprivedDid the foul take the scoring opportunity away?
- ExceptionsWas the fouled player already in his shooting motion, or was the defender trying to intercept or deflect the pass? If either is true, it is not a clear path foul.
The steps follow the wording of Rule 12B, Section I of the NBA rulebook. Failing any step means the foul is something else: a common foul, a transition take foul or a shooting foul.
What a transition scoring opportunity is
The rulebook defines the phrase, and the definition does a lot of quiet work. An opportunity exists when, after a change of possession, the offensive team is continuously advancing the ball while it holds an advantage from the speed of the play, the position of the defenders, or both. It does not exist if the offense does not push the pace right after the change of possession, if its progress has slowed considerably or stopped, if it runs or tries to run a set play in the half court, or if the offensive player is fouled in the act of shooting.
So a clear path foul cannot happen in a settled possession, however open the lane to the rim. It needs a change of possession that the offense exploits at once, and the usual sources are a steal, a long rebound and a blocked shot. The mechanics of those breaks are the subject of our explainer on how NBA teams score in transition.
The tip of the circle
The landmark for ball position is the free throw circle at the end of the floor the offense is leaving. Its tip is the point on that circle nearest midcourt. With the free throw line 19 feet from the endline and the circle's radius at 6 feet, the tip sits 25 feet out. A foul committed while the ball is still inside that mark, as when a rebounder is grabbed the instant he turns upcourt, is too early to be a clear path foul no matter how empty the floor ahead of him is.
No defender ahead, in practice
This is the test that decides nearly every review.
"Ahead" means nearer to the basket the offense is attacking. The rule counts every defender, and the fouler is one of them. If the man committing the foul is in front of the ball handler, the play fails the test at once, which means a clear path foul is by its nature a foul from behind or from the side. A defender who has turned to face the dribbler and takes contact in the chest may have committed a blocking foul. He has not committed this one.
One retreating opponent is enough
A single defender ahead of the play switches the rule off. He does not need to be in the dribbler's way. He does not need to be capable of stopping anything. A guard jogging back along the far sideline, forty feet from the ball and facing the wrong direction, is ahead of the scoring opportunity if he is closer to the baseline than the offensive player is.
That is deliberate. The current wording asks where the defenders were, not what they could have done, and the league accepted some odd results at the margin in exchange for a line officials can find on a frozen picture.
The defender who is level
The hard case is the opponent running stride for stride with the ball handler. The rulebook says "ahead" and supplies no measurement, no reference to feet or torsos or which body part governs. On the floor it is close to impossible to judge at full speed, with two players sprinting side by side and a third arriving from behind.
So it is judged on a screen. The review freezes the play at the moment of contact and compares positions along the length of the floor. The word in the rule is "ahead," so on the plain text a defender who is merely level has not switched it off, and one whose body is in front has. Calls on these plays turn on inches, and two crews will not read every freeze-frame alike. An honest description of the standard is that it is exact in principle and close in practice.
The moment that matters
Every position check is taken "when the foul occurs." Where the defenders were two seconds earlier is irrelevant, and so is where they would have been a second later. A defender who was ahead and has just been passed does not count. Neither does a teammate sprinting back who would have caught up by the free throw line. The rule asks about one instant, and only that one.
The two carve-outs: the act of shooting and the play on the pass
The rule ends with a sentence that takes two situations out of it: a clear path foul cannot occur if the offensive player is fouled in the act of shooting, or if the foul is caused by the defender's attempt to intercept or deflect a pass intended for the offensive player with the transition scoring opportunity.
Fouled in the act of shooting
A player who has started his shot when the contact comes gets an ordinary shooting foul. If the shot misses he has two free throws, or three beyond the arc. If it goes in he has the basket and one. In neither case does his team keep the ball afterward.
That makes the shooting exception a discount for the defense, and it is fair to ask why it is there. The answer is that the clear path penalty exists to restore a scoring chance that was taken away. A player who got his shot off had his chance.
Where the shooting motion begins is its own question, treated at length in our guide to the NBA's continuation rule. On a drive it normally starts at the gather. The rulebook then adds a parenthesis written for exactly the breakaway wrap-up: in "a take foul situation when the clocks are not expiring, the shooting begins when the player's shoulders start upward." A ball handler who feels a hand on his back at the three-point line and flings the ball toward the rim has not earned a shooting foul by gathering. He has to have actually started up.
A real attempt at the pass
The second exception protects defense. A long outlet pass is thrown ahead to a streaking wing, a defender closing from behind lunges for it, misses the ball and crashes into the receiver. Every positional test may be satisfied. It is still a common foul, because the contact was "caused by the defender's attempt to intercept or deflect" the pass.
Note how narrow the wording is. It covers a play on a pass. It does not cover a play on the dribble. A defender who reaches from behind for a live dribble, gets arm instead of ball, and has nobody ahead of him has committed a clear path foul, and it does not help him that he was honestly going for the steal. That asymmetry surprises people. The rulebook reserves its "play on the ball" language for the take foul, discussed below, and leaves it out here on purpose.
Why the fouled player does not need the ball
The first test speaks of a foul on "any offensive player." The penalty clause speaks of "an offensive player, or a teammate." Between them they make it plain that the victim of a clear path foul and the player with the scoring chance can be two different people.
Picture a two-on-none break after a steal. The ball handler is at midcourt with a teammate a few feet to his left, and the nearest defender is behind both of them. The defender cannot reach the ball, so he grabs the teammate around the waist. The ball handler, startled, pulls up. That is a clear path foul. The foul was on an offensive player, during the opportunity, with nobody ahead, and the player with the chance to score had control of the ball. The teammate who was grabbed shoots the two free throws.
The pass that has to be in the air
A second version involves the receiver. The rule is satisfied if the player with the scoring opportunity "is in control of the ball or a pass to him has been released." The word is released. Not thrown and caught, and not about to be thrown.
Timing therefore splits one play into two rulings.
A rebounder looks upcourt and sees a teammate alone at the far three-point line. A defender next to that teammate holds him by the arm. If the hold begins before the rebounder lets go of the outlet pass, the clear path rule cannot apply, since no pass to the fouled player had been released. Officials then look to the take foul, or to an old provision that still sits in the same list and awards two free throws when a defender deliberately fouls an offensive player "without the ball when his team has at least a one-man advantage on a fast break."
If the hold comes a half-second later, with the ball in flight, and the defender is not making a play on the pass, every element is present.
Defenders who know the rule foul early for that reason. Fouling the likely receiver before the pass exists is cheaper than fouling him after.
How replay settles it
Clear path is one of the few fouls in the NBA that officials may send to review at any point in a game on their own authority. Rule 13 lists it among the replay triggers: officials may go to the monitor when they "are not reasonably certain whether a personal foul called at any time during a game met the criteria for a clear-path-to-the-basket foul."
Two things follow from that wording. There must be a foul called on the floor first; replay does not create a clear path foul out of a no-call. And the trigger works in both directions. A crew that called a clear path foul can check it, and a crew that called a common foul on a breakaway can check whether it deserved more.
- Foul calledAn official whistles a personal foul on a defender during a fast break and signals for a review.
- Benches toldThe crew informs both teams that the play is going to replay, and the calling official goes to the courtside monitor.
- Positions checkedThe review looks at whether the ball was past the tip of the backcourt circle, whether any defender was ahead, and whether the offensive player had the ball or a released pass.
- Chance and exceptionsIt then asks whether the foul took away a transition scoring opportunity, whether the shooting motion had started, and whether the defender was playing the pass.
- ContactOfficials may also consider whether any unnecessary contact or unsportsmanlike act occurred.
- RulingThe foul is announced as a clear path foul, a common foul, a transition take foul, a shooting foul or a flagrant, and the matching penalty is administered.
The procedure described in Rule 13 of the NBA rulebook. The Replay Center Official reviews the clear path question with the official who called the foul; a flagrant foul, if one is found, is decided by the officials at the arena.
What the monitor can change
Rule 13 lists the matters a clear path review may look at, and each can move the call. The three position checks and the "deprived" question decide between clear path and something lesser. The shooting-motion check can turn the play into a shooting foul. The pass check can make it a common foul. The item on "any unsportsmanlike acts or unnecessary contact" is the door to an upgrade, and it is how a breakaway foul becomes a flagrant. The current list also lets the review assess or rescind a flopping violation close to the foul, and check whether an eight-second backcourt violation happened before the player was fouled.
What the review cannot do is decide there was no foul. That question is outside its scope. A coach who believes his defender never touched anyone has a different tool, the challenge, which Rule 14 allows for any personal foul called on his own team. The full list of triggers and limits is in our explainer on what NBA officials may take to the monitor.
The video is reviewed by the Replay Center Official together with the official who made the call. The rulebook asks that reviews be finished within two minutes where possible.
Clear path against the transition take foul
For the 2022-23 season the NBA added a second, lighter rule aimed at the same family of plays. The transition take foul catches the deliberate foul that stops a fast break when the clear path tests are not met, most often because a defender has got back.
The rulebook defines it with four conditions. The defender commits a take foul, meaning a foul in which he makes no play on the ball. It happens during a transition scoring opportunity or immediately after a change of possession, before the offense can advance. It does not meet the criteria for a clear path foul. And it does not occur in the last two minutes of the fourth period or of any overtime.
| Point of comparison | Clear path foul | Transition take foul |
|---|---|---|
| Free throws | 2 | 1 |
| Who shoots | The player who was fouled | Any player on the floor for the offended team |
| Possession afterward | Offended team, sideline | Offended team, sideline |
| Defender ahead of the play | Not allowed | Allowed |
| Play on the ball | No defense, except a play on a pass | A legitimate play on the ball means no take foul |
| Last two minutes of the fourth quarter and overtime | Still applies | Does not apply |
| Introduced | In its present form for 2018-19 | 2022-23 |
Which one applies when a defender is still back
The third condition answers it. A take foul is by definition a foul that is not a clear path foul, so officials test for clear path first. If no defender was ahead and the other conditions hold, the two-shot penalty applies. If a defender was ahead, the play drops to the take foul question: did the fouler make a play on the ball, or did he just stop the break?
The two rules therefore stack by severity. A break with nobody back is protected by two shots and the ball. A break with someone back is protected by one shot and the ball. A defender who makes an honest attempt at the ball with a teammate behind him to help has committed an ordinary foul.
The late-game difference
The take foul switches off in the last two minutes of the fourth quarter and of overtime, so that a trailing team can still foul on purpose to stop the clock. The clear path rule has no such window. A team down three with forty seconds left that grabs a ball handler on a breakaway, with every defender behind him, has handed over two free throws and possession, which very nearly ends the game. Late-game timing rules, including how the final two minutes of an extra period are treated, are set out in our guide to NBA overtime.
Clear path against a flagrant: which penalty takes over
Breakaways are where hard fouls happen. A defender chasing from behind at full speed, swinging at a ball held over a leaping player's head, is in exactly the position that produces dangerous contact, and the same play can satisfy the clear path tests and the flagrant definition together.
The rulebook treats them as different questions. Clear path is about position. A flagrant foul, in Rule 12B, Section IV, is about the contact: a Flagrant 1 is contact "interpreted to be unnecessary," and a Flagrant 2 is contact that is "unnecessary and excessive."
One foul gets one penalty, and the flagrant is the one that survives. When the clear path review turns up unnecessary contact, the officials rule the foul a flagrant and administer that.
On the scoreboard the difference is small. A Flagrant 1 also brings two free throws and the ball. The differences are in the details and in what follows.
| Consequence | Clear path foul | Flagrant 1 | Flagrant 2 |
|---|---|---|---|
| Free throws | 2 | 2 | 2 |
| Possession | Offended team | Offended team | Offended team |
| Throw-in spot | Sideline nearest where play was interrupted | Free throw line extended | Free throw line extended |
| Shot clock | Depends on the throw-in spot | Full 24 | Full 24 |
| Ejection | None | On a player's second in the game | Immediate |
| League discipline | None attached | Counts toward the league's flagrant penalties | Counts, more heavily |
For the team that was fouled, then, the upgrade changes little. For the defender it changes a great deal, because flagrant fouls accumulate over a season and carry suspensions at set thresholds, as described in our explainer on flagrant fouls and the points system behind them.
The reverse situation needs stating too. A foul that fails the clear path tests can still be flagrant. A defender ahead of the play does nothing to excuse a shove in the back of an airborne player.
The administration: who shoots, where the ball goes, how the foul counts
The shooter. Under Rule 9 the free throws awarded for a personal foul are taken by the player who was fouled. For a clear path foul that is whoever was fouled, with or without the ball. A team cannot pick its best shooter, which is one of the practical differences from the take foul, where any player on the floor may take the single attempt. If the fouled player is hurt and cannot shoot, the ordinary substitution rules for an injured free throw shooter apply, and under them the opposing coach chooses the replacement from the offended team's bench. The procedure at the line is covered in our guide to NBA free throw rules.
The lane. Possession is already decided, so the second free throw does not stay in play and there is no rebound to fight over.
The throw-in. The offended team takes the ball "on the sideline nearest the spot where play was interrupted." Since these fouls usually happen between midcourt and the three-point line, the offense normally restarts in its frontcourt.
The shot clock. No special provision exists for clear path, so the general rules for a defensive foul apply. If the throw-in is in the backcourt the clock is set to 24. If it is in the frontcourt the clock keeps what it had or goes to 14, whichever is greater.
The foul count. The defender is charged with a personal foul, one of his six. His team is charged with a team foul. The rulebook is explicit that clear path fouls "carry their own separate penalties and are included in the team foul total," which cuts two ways. Being in the penalty adds nothing to a clear path foul; it is two shots and the ball in the first minute of a quarter and in the last. But the foul does count toward the limit, so it can put the defense into the penalty for the next common foul.
The record. Nothing further attaches. There is no technical, no unsportsmanlike designation and no step toward ejection. A player could in theory commit several in a game and be disqualified only by reaching six personals.
The 2018 rewrite and what the simplified test removed
A clear path rule was in the NBA book long before the current one. By the middle of the 2010s it had become one of the least loved passages in it, among officials as much as anyone.
The earlier wording asked for judgments about the whole sequence rather than one moment. Had the play originated in the backcourt? Was there a defender between the ball and the basket, a question that invited officials to weigh where a defender was heading as well as where he stood?
Reviews under that standard were slow because they could not be settled from a single frame. Officials had to run the play backward and forward, tracking who had been where and when, and then form a view about what a defender might have done. Reasonable crews came to different answers on similar plays. The pause in the game was long and the explanation afterward was usually unsatisfying.
In September 2018 the Board of Governors approved a simplified rule for the 2018-19 season, in the same package that reset the shot clock to 14 seconds after an offensive rebound. The league described the aim as bright-line standards based on where players were at the time of the foul, with less judgment and fewer variables.
Two requirements went.
- Officials no longer decide whether a defender was between the ball and the basket. Only "ahead" matters, judged at the moment of the foul.
- The play no longer has to start in the backcourt, since a transition chance can begin with a steal in the frontcourt.
The same rewrite set out the two exceptions in their present form, for the act of shooting and the play on a pass.
The trade was accuracy in the abstract for consistency in fact. The old rule tried to identify fouls that truly cost a team a layup and failed to do so predictably. The new one identifies a set of positions and accepts that a defender forty feet from the ball can switch it off. It has been the better rule. Reviews are shorter, and the argument after one is about where a foot was, which is at least an argument that film can settle.
How college, FIBA and high school punish the same foul
No other major rulebook has a clear path rule by that name, apart from the WNBA, which uses the NBA's term. The others fold the breakaway foul into a broader category of fouls judged by intent and by the advantage they take away.
| Rulebook | What the breakaway foul is called | Penalty |
|---|---|---|
| NBA | Clear-path-to-the-basket foul | 2 free throws and possession |
| FIBA | Unsportsmanlike foul | 2 free throws and possession |
| NCAA men | Flagrant 1 personal foul | 2 free throws and possession |
| High school (NFHS) | Intentional foul | 2 free throws and possession |
The price is the same everywhere. What differs is how an official gets there.
FIBA
International rules list several kinds of contact that make a foul unsportsmanlike. Two are aimed at fast breaks. One is unnecessary contact by a defender to stop the progress of the offensive team in transition. The other is the closest thing to clear path in any book: illegal contact from behind or from the side on an opponent who is progressing toward the basket with no defender between him, the ball and the basket. Both apply until the offensive player begins the act of shooting.
A FIBA unsportsmanlike foul also carries a personal consequence the NBA's clear path foul does not. A player charged with two in a game is disqualified. Other differences between the codes are in our explainer on FIBA rules and NBA rules side by side.
College and high school
American amateur rules ask about the defender's purpose more than about a diagram. High school's intentional foul includes contact that neutralizes an opponent's obvious advantageous position, which describes a breakaway grab precisely. The NCAA men's book reaches the same play through its Flagrant 1 category, aimed among other things at contact that is not a legitimate attempt to play the ball or the player. The NCAA women's book has its own wording for the same foul and is best read directly. None of them has a landmark like the tip of the circle or a requirement that no defender be ahead, so the call rests on what the official saw the defender trying to do. The wider contrast is in our guide to how college rules differ from the NBA's.
A consequence is that college crews are judging intent at full speed, without the positional checklist that makes the NBA call reviewable frame by frame. The professional rule is more mechanical, and on this play mechanical is an advantage.
The clear path foul calls fans get wrong
Arguments about this rule in the stands tend to be arguments about the old one, or about fairness. The current test is narrower and stranger than either.
| What the crowd sees | Ruling | Why |
|---|---|---|
| A foul from behind on a breakaway, with one defender jogging back ahead of the play | Not clear path | Any defender ahead ends the test, wherever he is |
| A deliberate wrap-up in the half court to stop a drive | Common foul | No transition scoring opportunity exists in a set possession |
| A swipe at the dribble from behind that catches arm, nobody ahead | Clear path | Playing the ball is no defense unless the ball is a pass |
| A lunge at an outlet pass that takes out the receiver | Common foul | The contact came from an attempt to intercept the pass |
| A grab on the rebounder under his own basket as he turns upcourt | Not clear path | The ball has not passed the tip of the backcourt circle |
| A hold on a teammate running beside the ball handler, nobody ahead | Clear path | The foul may be on any offensive player |
The foul from behind with a defender ahead
This is the complaint officials hear most. The dribbler is clearly gone, the fouler is clearly beaten, and a single opponent is drifting back near the far corner. To a fan that defender is scenery. To the rule he is decisive. The play is very likely a transition take foul, worth one shot and the ball, and the crowd's sense that the punishment is light is not unreasonable. It is the cost of having a bright line.
The half-court wrap-up
A center caught on a switch grabs a guard who has turned the corner in a set offense, and the rim is wide open behind him. Open rim, deliberate foul, no clear path. The rule protects fast breaks only, and its definition of a transition opportunity ends once the offense "runs or attempts to run a set play or action in the half-court."
The clean-looking swipe
The defender insists he went for the ball, and he did. It makes no difference. If he fouled the dribbler from behind with nobody ahead, his intent is not one of the tests. Fans who have absorbed the take foul rule, where a legitimate play on the ball matters a great deal, tend to carry that idea over to a rule that never contained it.
One judgment to end on. The clear path rule is sometimes criticized as too technical, a matter of freeze-frames and landmarks. That is its virtue. The play it governs happens at a sprint, and a rule that asked officials how they felt about the foul would be called differently every night. More of the league's foul rules are collected with our other American sports guides on the USA hub.
