Iowa Motorcycle Test Driving Without A Motorcycle License In Iowa?

Driving without a motorcycle license in Iowa? - iowa motorcycle test

I have a valid driver's license, I have passed a motorcycle driving license (written test). I still pass the driving test, but would get some exercise. I live in Iowa and can ride a motorcycle, which says your motorcycle with the driver of the motorcycle license. Problem is that I still here and no one knows. I wonder what punishment or fine for driving a motorcycle with only a driver's license and a valid motorcycle license.
