VIRGINIA DWI NOT SUBSTANTIALLY SIMILAR

N.C. Gen. Stat. Ann. § 20-179
(c) Determining Existence of Grossly Aggravating Factors.--At the sentencing hearing, based upon the evidence presented at trial and in the hearing, the judge, or the jury in superior court, must first determine whether there are any grossly aggravating factors in the case. Whether a prior conviction exists under subdivision (1) of this subsection, or whether a conviction exists under subdivision (d)(5) of this section, shall be matters to be determined by the judge…The grossly aggravating factors are:
(1) A prior conviction for an offense involving impaired driving if:
a. The conviction occurred within seven years before the date of the offense for which the defendant is being sentenced; or
b. The conviction occurs after the date of the offense for which the defendant is presently being sentenced, but prior to or contemporaneously with the present sentencing; or
c. The conviction occurred in district court; the case was appealed to superior court; the appeal has been withdrawn, or the case has been remanded back to district court; and a new sentencing hearing has not been held pursuant to G.S. 20-38.7.

Each prior conviction is a separate grossly aggravating factor.

(3) If there was at that time 0.08 percent or more by weight by volume of alcohol in the accused's blood or 0.08 grams or more per 210 liters of the accused's breath, it shall be presumed that the accused was under the influence of alcohol intoxicants at the time of the alleged offense; or
