What does gee and haw mean to a horse?

"Gee" and "Haw" are commands used to guide a horse in harness, specifically in a team of horses pulling a wagon or plow.

* Gee means "turn right."

* Haw means "turn left."

These commands were traditionally shouted by the driver or wagoner to direct the horses.

It's important to note that these commands are not used with horses ridden under saddle, only with horses pulling a load.
