Of all the rules in the game, icing is one of the few you really need to know to follow what’s happening on the ice. It comes up multiple times every game. And honestly? It’s also one of the most confusing rules for newer fans.
So let’s fix that.
Icing is called when a player shoots the puck from his side of the center red line all the way past the opposing team’s goal line — without anyone touching it along the way. The result is a stoppage of play and a faceoff back in the zone of the team that shot the puck. And that team doesn’t get to make any line changes before the faceoff.
That’s the core of it. But the icing rule has a lot of wrinkles to it — and once you understand them, you’ll see a completely different game every time you watch.
| Icing Topic | Quick Summary |
|---|---|
| Origin | Introduced in 1937 to stop teams from wasting time |
| The basic rule | Shoot from your side of the red line past the goal line = icing |
| Hybrid icing | Race to the faceoff dot, not the end boards (NHL since 2013–14) |
| No line changes | The team that iced the puck is stuck with tired players |
| No timeout either | Can’t call a timeout after icing — that one surprises people |
| Penalty kill exception | Shorthanded teams ARE allowed to ice the puck |
Why Was the Icing Rule Introduced?
The icing rule was first introduced in 1937 because teams in the NHL had started to shoot the puck all the way down the ice as a stalling tactic at the end of games when they had the lead.
With no stoppage in play, a team could simply shoot the puck from one end to the other and let the clock run. Seconds burned. The crowd fumed. The trailing team had no way to get the puck back.
Problem: Who wants to pay to watch players just heave the puck down the ice all game?
Solution: Introduce the icing rule.
The fix was straightforward: if you shoot the puck from your side of the center red line all the way past the goal line at the other end, play stops. Faceoff in your own zone. Now there’s a real consequence for firing it down the ice just to kill time.
What Is the Basic Icing Rule?
Here’s the rule in plain terms:
The center red line divides the rink in half. If any player shoots the puck from anywhere on his side of that line — the side with his own goalie — and the puck travels all the way past the goal line at the other end without being touched, icing is called.
A few things to keep in mind from the diagram:
- It doesn’t matter where on your side of the red line you shoot from. Deep in your own end, just behind center — doesn’t matter. If it crosses the goal line untouched, it’s icing.
- If the puck is shot before the red line but doesn’t quite reach the goal line, it’s NOT icing. It has to travel the full distance.
- The linesman has some discretion. If the puck is slowly drifting toward the goal line and the opposing team could have reasonably played it but chose not to, the linesman can wave off the icing. Players can’t just stand there and let the puck trickle down — they have to make an effort.
The NHL is always trying to keep the game moving, and that linesman discretion is one of the ways they preserve flow.
What Are the Three Types of Icing?
The NHL, currently, uses the hybrid icing rule but it has evolved quite a bit since it was introduced in 1937.
There have been three versions of it — and understanding why the NHL changed things tells you a lot about how the league thinks about player safety.
1. Touch Icing (The Original)
Under the original rule, icing wasn’t automatic. After the puck crossed the goal line, a race was on. If the defending player touched the puck first, icing was called. If the attacking player (the team that shot it) touched the puck first, icing was waved off.
The problem? That race was dangerous. Defenders were sprinting toward the end boards, and attacking players were right behind them — often checking them hard from behind into the boards just as they reached the puck. It caused serious injuries. Something had to change.
2. No-Touch Icing / Automatic Icing
The IIHF (international hockey) adopted no-touch icing in 1990, with the death of Czech player Luděk Čajka — who died following a severe collision with the boards during an icing race — often cited as a major factor in that decision. It was a turning point. Under no-touch icing, the moment the puck crosses the goal line, icing is called automatically — no race required.
The NHL didn’t follow immediately, but the pressure to address player safety was building.
3. Hybrid Icing (What the NHL Uses Today)
The NHL adopted hybrid icing starting in the 2013–14 season — a middle ground between touch icing and no-touch icing.
Here’s how it works: when a potential icing is developing, the race isn’t to the end boards anymore. It’s to the faceoff dots in the defensive zone. The linesman watches who wins the race to those dots:
- If the defending player gets there first, the whistle blows. Icing called.
- If the attacking player (the team that shot it) gets there first, the play continues — and whoever touches the puck at the boards determines whether it’s icing or not.
This keeps the competitive element of the race alive while getting rid of the dangerous collisions at the boards that were causing serious injuries. It’s a change that worked — and you’ll rarely hear anyone argue for going back.
Here’s how the rule has evolved over the decades:
| Year | Change |
|---|---|
| 1937 | Icing rule introduced in the NHL — touch icing, race to the end boards |
| 1990 | IIHF adopts no-touch (automatic) icing following the Čajka incident |
| 2005–06 | NHL adds no-line-changes rule after icing to increase the penalty |
| 2013–14 | NHL adopts hybrid icing — race moves from end boards to faceoff dots |
How Do You Know When Icing Is Called? (The Referee Signals)
This is something even longtime fans often miss. The officials actually signal what’s happening before the whistle blows — if you know what to look for.
Delayed icing signal: As a potential icing develops, the linesman raises one arm straight up in the air. This is the signal that icing may be coming, but hasn’t been called yet. Play continues until the race to the faceoff dot is decided.
Icing waved off (the washout signal): If the icing is waved off, the linesman extends both arms out to the sides at shoulder height — like a “safe” call in baseball. No icing. Play on.

Next time you’re watching a game and a puck gets fired down the ice, look for that raised arm. It’ll change how you watch the play develop.
What Happens After Icing Is Called in Hockey?
Getting caught for icing is not just a whistle and a faceoff. There are three things that happen to the team that iced the puck, and all three hit at the same time.
1. Faceoff in your own zone. The puck comes back to the faceoff circle closest to your goaltender. The opposition now has a shot attempt practically gift-wrapped for them.
2. No line changes. This is the big one. The team that iced the puck cannot make a line change before the faceoff. Whatever exhausted group of players was on the ice when they iced it? They’re staying out there. Meanwhile, the other team gets to send out their freshest, most dangerous line. This rule was added after the 2004–05 lockout specifically to put more teeth in the icing rule — and it worked.
3. No timeout. Here’s one most people don’t know: a team cannot call a timeout immediately after icing the puck. So there’s no escape hatch. You can’t ice it, call a timeout to rest your players, and reset. You’re stuck.
The combination of faceoff in your zone + tired players + no timeout is genuinely punishing. It’s why you see players fight so hard just to get the puck to the red line before they shoot it in.
How Do Players Avoid Icing in Hockey?
With any rule, players are smart enough to find the edge of it. And they have.
You’ll notice players often chip or loft the puck into the air rather than shooting it hard and flat along the ice. The goal isn’t that the puck magically stops short of the goal line — a puck in the air can still be icing if it crosses the line untouched. What players are really trying to do is give a teammate the chance to get to the puck first and touch it before it reaches the goal line — which immediately waves off the icing — or bank it off the glass in a way that creates a controlled bounce they can chase down.
It’s a fine line, and it doesn’t always work. But you’ll see it attempted many times a game once you know what you’re looking for.
Can You Ice the Puck on a Penalty Kill?
Yes — and this is the one big exception to the rule.
A team that is shorthanded (fewer players on the ice because of a penalty) is allowed to ice the puck without the play being stopped. The icing exception for the penalty kill exists because without it, a power play would be nearly impossible to defend.
Think about it: a shorthanded team can’t make line changes, can’t get fresh players on, and is already outnumbered. If they couldn’t even ice the puck to relieve pressure, a power play would be overwhelming. The exception levels things out just enough.
It also keeps the game flowing. Without this exception, penalty kill teams would ice the puck constantly just to get a rest — resulting in a stream of stoppages and a terrible viewing experience. The NHL doesn’t want that.
What Is Gaining the Red Line?
Once you understand icing, you’ll start to notice one of the most common plays in hockey: players working to “gain the red line.”
Gaining the red line just means skating the puck up to — and over — the center red line before shooting it into the other team’s zone. Once a player is past the red line, they can shoot the puck all the way down the ice without it being icing.
You’ll see this happen hundreds of times a game. A player gets the puck in his own zone and skates hard toward center ice. He’s not trying to rush the net — he’s just trying to get to the red line so he can shoot it in safely.
Why bother?
- Once the puck is shot into the zone from past the red line, the team can make a line change without worrying about icing
- Or they can shoot it in and start a forecheck — chasing down the puck in the other team’s zone to create a scoring chance
It’s one of the most fundamental tactics in the game, and it’s all driven by the icing rule. Next time you’re watching and a player skates hard up the ice without really seeming to be going anywhere — he’s just trying to gain the red line. That’s the whole play.
Key Takeaways
- Icing is called when a player shoots the puck from his side of the center red line past the opposing goal line without anyone touching it
- The result: faceoff in the offending team’s zone, no line changes, and no timeout — all at once
- The NHL uses hybrid icing since 2013–14: the race is to the faceoff dot, not the end boards — safer for players
- The linesman raises one arm to signal delayed icing; both arms extended sideways means the icing is waved off
- Shorthanded teams on the penalty kill are allowed to ice the puck — the one exception
- Players have adapted by flicking the puck high in the air — far enough to relieve pressure, but not far enough to cross the goal line
Frequently Asked Questions
Can goalies ice the puck?
Yes. If the goalie shoots the puck down the ice like any other player, it can absolutely be called icing. The goalie isn’t exempt from the rule.
Can a goalie wave off icing?
Not exactly — but a goalie can prevent icing by coming out to play the puck before it crosses the goal line. If the goalie touches it before it gets there, no icing.
What if a player from the other team touches the puck?
If an opposing player touches the puck in any way before it reaches the goal line, the icing is waved off and play continues. This sometimes happens on deflections — a puck gets redirected off an opposing player and still travels all the way down the ice. No icing in that case.
What is icing in recreational hockey?
In most recreational leagues, icing is called automatically the moment the puck crosses the goal line — no race, no linesman discretion. It’s the no-touch version, which keeps things simpler and safer for players who aren’t professionals.
Why can’t you ice the puck from a faceoff?
You can — icing can occur directly off a faceoff if the puck crosses the goal line untouched. In practice it’s often waved off depending on how the puck is played immediately after the drop, but there’s no blanket exception for faceoffs. It’s one of the lesser-known wrinkles in the rule.
