Rule 20. Lost Helmet or Broken Equipment
Blue Book 2026, Part 1, Rule 20 · Interruptions and Restarts After Break in Play
In plain English
Lost helmet or dangerous broken tack stops the game.
- A lost helmet stops the game, but the umpire waits for a neutral moment rather than killing an attack, so the player can go back for it.
- Damaged or broken tack that could hurt a player or pony stops the game the same way, when play is neutral.
- Four faults stop it immediately, whatever the state of play: a broken bit, a broken rein (either of a double), a broken girth, and trailing bandages.
