A lane violation happens when a player from either side reaches the key before a free-throw shooter releases the ball while shooting. The inclusion of the restricted area arc just beneath the basket, where the defensive player cannot impose an offensive foul on the opposing player, is a new invention. Before this change, players were allowed into the key to defend or pass the ball out of bounds regardless of where they stood on the floor. Lane violations are worth 1 point unless the shot clock is running down, in which case there is no penalty. If a team commits 5 lane violations in a single game, it will be issued a technical foul and awarded 2 points deducted from its score. This rule was introduced in 1986 to curtail excessive fouling by teams sitting behind closed doors games. Before the introduction of the shot clock, teams would often use timeouts to set up plays, so allowing them into the key without penalty was necessary to prevent these setups from being ruined by defenders entering the area. Now that coaches don't need to worry about wasting time with such maneuvers, they use their timeouts instead to protect themselves from opponents who might try to steal the ball away from them inside the key. The NBA adopted several other changes for the 1986-87 season, most notably reducing the height of the backboard from 12 feet to 10 feet 9 inches.
