1. Penalties are said to have expired at the exact time of the penalty on the scoreclock plus the length of the penalty. For instance, if a minor penalty is called at 4:58, it expires at 2:58. If a major penalty is assessed at 13:05, it expires at 8:05, whether or not the skater steps onto the ice at that exact second. For coincident minor penalties and misconduct penalties, the skater is allowed to return to the ice only at the first whistle after the penalty time has expired.

2. Only penalties displayed on the scoreclock allow a team to gain extra skaters during game action when they expire. Penalties not displayed on the scoreclock include coincident minors or majors, misconducts, game misconducts, and coincident match penalties.

3. Penalties which must be displayed on the scoreclock include minors, double minors, majors, and match.

4. Penalties with a delayed start time will be displayed on the scoreclock only when their time has started.

5. In the case of misconduct penalties, the skater is allowed to return to the ice only after the first whistle after the expiration of his penalty.

6. In the case of more than one penalty to a team, skaters are allowed to return to the ice only when their own penalty has expired. A skater who comes onto the ice after a teammate’s penalty has expired – not his own – will be subject to further penalty.
