Strong words considering that when you change your name on your driver's license you have to prove to the DMV that your name has been legally changed. That is where you would show your marriage certificate as proof. Since the DMV has done the legal leg work of verifying your name change, your driver's license (or govt issued i.d.) is adequate proof that you are the same person as your birth certificate says you are. even if the last name is different.
OP have you spoken with DCL or your TA? They would have the most up to date info and could confirm the info that others have posted.
