The District Attorney can quickly move to have your driving privileges in Tennessee revoked. Otherwise at Trial, the Judge alone decides whether a violation of Implied Consent occurred or not. With earlier revocations, the revocation period can be longer than one year. It is possible to be convicted of DUI and not Implied Consent, and vice versa. it is also possible for a Restricted License to issue for a year after the DA goes after you, and then you are convicted of DUI a year later but you are now a licensed driver.
