Penalties

A penalty in ice hockey is a punishment for inappropriate behavior. Most penalties are enforced by detaining the offending player within a penalty box for a set number of minutes during which the player can not participate in play. The offending team usually may not replace the player on the ice, leaving them short-handed (as opposed to full strength) or penalty killing until the penalty expires and the player returns to the ice. The opposing team is said to be on a power play, having one player more on the ice than the short-handed team. While standards vary somewhat between leagues, most leagues recognize several common degrees of penalty, as well as common infractions. The statistic used to track penalties was traditionally called Penalty Infraction Minutes (PIM), although the alternate term Penalties in Minutes has become common in recent years.

The referee(s) make most penalty calls. Linesmen generally may call only certain obvious technical infractions such as "too many players on the ice". When a penalty is called, the official will put an arm in the air; the official will stop play only once the offending team has control of the puck, or play is stopped by normal means. A delayed penalty is one in which the a penalty is called but play is not yet stopped because the opposing team retains the puck. The goaltender of the non-offending team will often go to the players' bench upon seeing the arm signal to allow an extra attacker on the ice until the play is stopped.
