How do I compare vector3 values?

velo = BodyAngularVelocity

if steer.Steer == 0 and driftdirection == "left" then
                repeat
                wait(.5)
                velo.angularvelocity = velo.angularvelocity + Vector3.new(0,-.1,0)
--[[The Problem is after the Or]]--->   until steer.Steer ~= 0 or velo.angularvelocity == Vector3.new(0,0,0)
                    if velo.angularvelocity <= Vector3.new(0,0,0) then
                        velo.angularvelocity = Vector3.new(0,0,0) --[[Up to here]]
                    end
        end
