Step 1
Understand the basics of lane violations. Any player, whether they are on offense or defense, can commit a lane violation. So make sure you identify which side each player is on and keep that in mind, because your violation calls will depend on who does what.
-
Step 2
Be familiar with these violations:1. If the shooter steps on or over the free throw line, that is a violation on the shooter.2. If any player (offense or defense) steps into the painted area before the ball leaves the shooter's hand, that is a violation. 3. No player (offense or defense) who is outside of the three-point area can cross the three-point line anytime after the referee gives the ball to the shooter.- Once again, the players behind the three-point line are allowed to enter at the same time that the other players can enter the paint. The same league rules apply to both.

Step 3
Do not blow your whistle the moment you see the violation occur. Lane violations are the only delayed calls in basketball. This means that even if a violation occurs, the referee should not blow their whistle right away. The call is only made if the outcome of the free throw is effected by the violation. Consider the following scenarios:- Scenario 1: A violation is committed by the defense. The referee puts her fist out. She will only make the call if the shot is missed by the shooter.- Scenario 2: A violation is committed by the offense. The referee puts his fist out. He will only make the call if the shot is made by the shooter.- Explainer: If the defense commits a violation but the shot is made, there is no reason to make a call because the offense gets the point.

Step 4
If the violation is on the offense and the shot was made, disallow the basket and take the point away from the offense. The free throw can not be re-attempted.
-
Step 5
If the violation is on the defense and the shot was missed, call the violation and award the shooter another shot.
