How to make a body velocity go forward for any body angular velocity rotation?

My issue: I have this code where it uses a body angular velocity to rotate this hoverboard. After the user stops holding A or D and wants to move forward it just moves in one direction not the turned direction is there a way to make this work?

Part of the code that does rotation and moving:

KeyHeld = false

function onKeyPress(inputObject,gameProcessed)
    if inputObject.KeyCode == Enum.KeyCode.A then
        KeyHeld = true
        if KeyHeld == true then
           	angularvelo.AngularVelocity = Vector3.new(0,2,0)
            wait()
        end
    end
end

function onKeyRelease(inputObject,gameProcessed)
    if inputObject.KeyCode == Enum.KeyCode.A then
		        KeyHeld = false
		angularvelo.AngularVelocity = Vector3.new(0,0,0)
    end
end

game:GetService("UserInputService").InputBegan:connect(onKeyPress)
game:GetService("UserInputService").InputEnded:connect(onKeyRelease)

KeyHeld2 = false

function onKeyPress(inputObject,gameProcessed)
    if inputObject.KeyCode == Enum.KeyCode.D then
        KeyHeld2 = true
        if KeyHeld2 == true then
           	angularvelo.AngularVelocity = Vector3.new(0,-2,0)
            wait()
        end
    end
end

function onKeyRelease(inputObject,gameProcessed)
    if inputObject.KeyCode == Enum.KeyCode.D then
		        KeyHeld2 = false
		angularvelo.AngularVelocity = Vector3.new(0,0,0)
    end
end
game:GetService("UserInputService").InputBegan:connect(onKeyPress)
game:GetService("UserInputService").InputEnded:connect(onKeyRelease)

KeyHeld3 = false

function onKeyPress(inputObject,gameProcessed)
    if inputObject.KeyCode == Enum.KeyCode.W then
        KeyHeld3 = true
        if KeyHeld3 == true then
	bodyvelo.Velocity = Vector3.new(-15,0,0)
            wait()
        end
    end
end

function onKeyRelease(inputObject,gameProcessed)
    if inputObject.KeyCode == Enum.KeyCode.W then
		        KeyHeld3 = false
	bodyvelo.Velocity = Vector3.new(0,0,0)
    end
end
game:GetService("UserInputService").InputBegan:connect(onKeyPress)
game:GetService("UserInputService").InputEnded:connect(onKeyRelease)
