TipsyNurse is correct, it is a separate application tha the Traffic Commissioner looks at. Because it is your second ban, so you have (at least) a 3 year ban, you will probably be called to a hearing where the commissioner considers your licence. Unless you were driving a goods vehicle when you were arrested, you will probably get a telling off and your HGV part restored after an extra wait of 3 months or so after your car licence is restored.
