ART. 1 . . . Other than the start of the game and each extra period, the teams will alternate taking the ball out of bounds for a throw-in. The team obtaining control from the jump ball establishes the alternating-possession procedure, and the arrow is set toward the opponent’s basket. Control may also be established by the results of a violation or foul, as in 4-3.
ART. 2 . . . To start the second, third and fourth quarters, the throw-in must be from out of bounds at the division line opposite the scorer’s and timer’s table.
ART. 3 . . . Alternating-possession throw-ins must be from the out-of bounds spot nearest to where the ball was located. An alternating possession throw-in must result when:
a. A held ball occurs.
b. The ball goes out of bounds, as in 7-3.
c. Simultaneous floor or free-throw violations occur.
d. A live ball lodges between the backboard and ring or comes to rest on the flange, unless a free throw or throw-in follows.
e. Opponents commit simultaneous basket-interference violations.
f. The point of interruption cannot be determined as in 4-36-2c.
ART. 4 . . . The direction of the possession arrow is reversed immediately after an alternating-possession throw-in ends. An alternating-possession throw-in ends when the throw-in ends as in 4-42-5.
ART. 5 . . . The opportunity to make an alternating-possession throw-in is lost if the throw-in team violates. If either team fouls during an alternating possession throw-in, it does not cause the throw-in team to lose the possession arrow. If the defensive team commits a violation during the throw-in, the possession arrow is not switched.
