It's the speed you slow down to when you hit turbulence so you don't die.

Wouldn't that be maneuvering speed?

Always practice safe flying... never penetrate rough air without protection.

Va is maneuvering speed. Vb is rough air penetration speed or Vra. They are usually close but not the same. They are obviously used for two different reasons.
