2006-07 NFHS Basketball Rules Interpretations
SITUATION 4: The horn sounds to end the third quarter. As the teams are heading to their respective benches, team members A1 and B1 verbally taunt one another. RULING: Double technical foul charged to A1 and B1. During the intermission between quarters, all team members are bench personnel. Both head coaches are indirectly charged with technical fouls and lose their coaching box privileges. Play will resume at the point of interruption, which is an alternating-possession arrow throw-in to begin the fourth quarter. (4-34-2; 10-4-1c Penalty)
