The rule stops teams from relieving pressure by repeatedly firing the puck the full length of the ice. The exact application depends on the league, especially whether it uses touch, no-touch or hybrid icing.
The NHL uses hybrid icing. The linesperson judges which player would reach the puck first by the time the race reaches the end-zone face-off dots, allowing play to be stopped before a dangerous collision at the end boards.
The basic icing sequence
- A player sends the puck from behind their team's side of centre.
- The puck travels beyond the opponents' goal line without entering the goal.
- No player makes a touch that nullifies the potential icing.
- The linesperson applies the league's race or touch standard.
- If icing is called, play restarts with a defensive-zone face-off for the offending team.
When icing is waved off
Icing may be waved off when the puck is touched or deflected in a way recognised by the rules, an opposing skater could reasonably play it, the goalkeeper attempts to play it, or the team shoots from the permitted side of centre. A puck that enters the goal is a goal, not icing.
In NHL play, a short-handed team is generally allowed to ice the puck while killing a penalty. Youth and international rules can differ, so the governing rulebook controls the exception.
Why the face-off matters
The NHL prevents the offending team from changing players after icing, apart from limited exceptions. A tired line must stay on while the attacking team can often send out fresh players and choose the defensive-zone face-off dot. That makes an unnecessary icing a tactical cost, not merely a stoppage.

Frequently asked questions
Why is icing sometimes not called?
A legal touch, playable puck, goalkeeper action, penalty situation or league-specific exception may cancel the potential icing.
What is hybrid icing?
The official predicts who would reach the puck first at the face-off dots and can stop play early to reduce high-speed end-board collisions.
Can an iced puck score a goal?
If the puck legally enters the opponents' goal, the goal counts and icing is not called.
