What Is Coincidental Penalties in Ice Hockey?

What are coincidental penalties, and how do they affect on-ice manpower?

Editor: Coach Mark • Updated: March 2, 2026

Short Answer

Coincidental penalties occur when players from both teams receive penalties at the same time, and teams usually continue playing with equal manpower.

Full Explanation

Coincidental penalties are assessed when opposing players commit infractions during the same sequence of play, often during scrums or altercations.

When equal penalties of the same duration are given to both teams, the penalized players go to the penalty box, but teams remain at even strength on the ice.

If penalties are of unequal duration, the situation may result in a power play for one team.

In some cases, coincidental minors lead to four-on-four play instead of five-on-five, depending on league rules and penalty combinations.

Why Coincidental Penalties Exist

The rule ensures fairness when both teams are equally responsible for misconduct and prevents one team from gaining an unintended advantage.

Key Takeaways

  • Coincidental penalties are given to both teams at the same time.
  • Equal penalties usually result in even-strength play.
  • Unequal penalties can create a power play.
  • Often occur during scrums or altercations.
