Signal to people coming towards a gate, but out of hearing, that the gate should be shut. The response to which should be to hold your hand in the air to show you have got the message and will shut the gate.

Red Ribbon

Worn on the tale of a known kicker. These horses should be kept at the back of the field until they become educated and no longer need to wear a ribbon.

Whip in the air

(usually by Field Master) This means stand still where you are, not wait until you get level with the Field Master and then stop.
