The rules new players trip over — offside, icing and penalties
Offside and icing explained properly, including the versions that differ between youth hockey, international hockey and the pros — plus what every penalty length actually means.
Four rules cause almost all the confusion in hockey: offside, icing, what happens during a delayed penalty, and how long someone actually sits. Here they are, including the parts that genuinely differ depending on where you play.
Offside
The rule: the puck must enter the attacking zone before the attacking players do. Specifically, a player is offside if they do not have skate contact with the neutral zone or with the blue line itself at the moment the puck completely crosses the determining edge of the blue line.
Three details people get wrong:
- Only one skate needs to be touching the blue line to be onside. The line itself counts as neutral territory.
- Your stick does not matter. It can be anywhere.
- It is about where the puck is when you are there, not about who arrives first in general.
Delayed (tag-up) offside is where the versions diverge. Under tag-up, when attackers are in the zone ahead of the puck the linesman raises an arm rather than blowing the whistle, and play continues if every attacker clears back out — "tags up" at the line. The NHL and the IIHF use tag-up at all levels. In USA Hockey it applies only to Youth 15-Only and above, Girls' 16U and above, High School and Adult classifications; younger age groups play immediate offside, so the whistle goes straight away.
If you are used to watching the NHL and you coach 12U, this is the rule that will surprise you.
Icing
The rule: a team shoots the puck from its own half, across the opponents' goal line, without anyone touching it. Play stops and the face-off comes back to the offending team's defensive zone.
Two versions exist:
- USA Hockey and Hockey Canada use automatic (no-touch) icing: play stops the instant the puck fully crosses the far goal line. Nobody has to race for it. This exists to remove the race that used to injure players.
- The NHL and the IIHF use hybrid icing: the linesman judges the race to the face-off dot, and blows it down if a defending player would win it. The NHL adopted hybrid icing for the 2013-14 season.
The short-handed exception — this one catches out experienced parents. Traditionally, a team killing a penalty may ice the puck freely, and that is still true in the NHL and IIHF. But in USA Hockey, a short-handed team may NOT ice the puck at 14U and younger (and the equivalent girls' levels): icing is enforced anyway, with a defensive-zone face-off, though the offending team is allowed a line change. That restriction took effect from the 2017-18 season.
Penalties, and how long they really are
| Penalty | Length | What actually happens |
|---|---|---|
| Minor | 2 minutes | Team plays short-handed. Ends early if the other team scores. |
| Double minor | 4 minutes | Two minors back to back — a goal ends the first half only. Typical call: high-sticking that draws blood. |
| Major | 5 minutes | Served in full regardless of goals scored. Often comes with a game misconduct. |
| Misconduct | 10 minutes | The player sits, but the team does not play short — a substitute goes on immediately. |
| Game misconduct | Rest of the game | Player is gone; team plays short only if a minor or major came with it. |
| Match | Rest of the game + review | For deliberate attempts to injure; carries further discipline. |
USA Hockey's rulebook confirms these standard lengths for periods of 17 to 20 minutes and for the Adult classification. Youth games with shorter periods often use shorter penalties — a minor might be 90 seconds. Check your league's rule.
The delayed penalty
When a team commits a penalty but the other team has the puck, the official raises an arm and holds the whistle until the offending team touches it. The team with the puck can pull its goaltender for an extra attacker in the meantime, because play cannot be stopped against them.
Two things new players get wrong here: your own team touching the puck does not stop play, and if you shoot it into your own empty net during a delayed penalty, that counts. It happens more often than you would think.
Four more that come up constantly
- Too many men on the ice. A minor. Usually a botched line change — the player coming on touched the puck before the player coming off reached the bench.
- Hand pass. You may bat the puck with your hand to a team-mate only in your own defensive zone. Anywhere else, it is a stoppage.
- High stick. Playing the puck with your stick above shoulder height is a stoppage; hitting an opponent in the face with a high stick is a minor, or a double minor if it draws blood.
- Puck over the glass. Shooting the puck directly out of play from your own defensive zone without it hitting the glass or another player is a delay-of-game minor in most rule sets. Ask your league — this one varies.
The one that is not a rule
"You cannot pass forward." You can. Hockey has no forward-pass restriction, only offside at the blue lines — and, in some rule sets, a two-line pass rule that the NHL abolished in 2005. Pass forward all you like.
