The Commonwealth appeals from the Court of Appeals affirmance of a Circuit Court order. The order prohibited the introduction of appellee’s prior DUI convictions during the prosecution’s case-in-chief. We granted discretionary review to clarify the important issues raised by this appeal.

Appellee was indicted by the Pulaski Grand Jury for Driving Under the Influence of Intoxicants, [hereinafter DUI] fourth offense, and Driving While License was Suspended, third offense. Prior to trial, appellee moved in limine to prohibit the introduction of her previous DUI convictions during the guilt phase of the trial. The Pulaski Circuit Court agreed with ap-pellee’s claim that undue prejudice would result. The Commonwealth, appellant herein, appealed this order to the Court of Appeals. The Court of Appeals, relying on Clay v. Commonwealth, Ky., 818 S.W.2d 264 (1991), affirmed the prohibition. We affirm the Court of Appeals for the reasons set out below.

The Commonwealth maintains that KRS 189A.010(4)(d) establishes a fourth or subsequent offense of DUI as a felony which includes prior DUI convictions as an element. This interpretation is critical to the Commonwealth’s position that prior DUI convictions are necessarily admissible during the prosecution’s case-in-chief. The Commonwealth relies on holdings in Ratliff v. Commonwealth, Ky.App., 719 S.W.2d 445 (1986), and Asher v. Commonwealth, Ky.App., 763 S.W.2d 153 (1988), as well as language in Hall v. Commonwealth, Ky., 817 S.W.2d 228 (1991). We do not agree with this interpretation and overrule the above noted cases to the extent they conflict with the following discussion of KRS 189A.010.

This Court first analyzed KRS 189A.010 in Commonwealth v. Ball, Ky., 691 S.W.2d 207 (1985), wherein we decided an ex post facto issue. In Ball, we opined that the intent of this newly enacted statute “was not to create a new offense, but to increase the severity of the penalty for driving under the influence of alcohol.” Ball, supra, at 209. Two years later, we reaffirmed that KRS 189A.010 “established one offense of driving under the influence” and that “[t]he number of offenses does not relate in any way to the basic charge of DUI.” Division of Driver Licensing v. Bergmann, Ky., 740 S.W.2d 948, 950 (1987). While both Ball and Bergmann dealt with the original version of KRS 189A.010, we see no reason to distinguish the present version of KRS 189A.010 enacted in 1991. The plain language of this statute makes it clear that the elements of DUI are contained in 189A.010(1). This section states:

No person shall operate or be in physical control of a motor vehicle anywhere in this state:

(a) While the alcohol concentration in his blood or breath is 0.10 or more based on the definition of alcohol concentration in KRS 189A.005;

(b) While under the influence of alcohol;

(c) While under the influence of any other substance or combination of substances which impairs one’s driving ability; or

[*528] (d) While under the combined influence of alcohol and any other substance which impairs one’s driving ability.

The elements required for violation of KRS 189A.010 are the operation or physical control of a motor vehicle coupled with one or more levels of impairment as outlined above.

Subsections two (2) and three (3) support the above reading of KRS 189A.010(1). Subsection two (2) of KRS 189A.010 defines the presumptions raised by various levels of blood alcohol content in “any prosecution for a violation of subsection (1).” Subsection three (3) states that the legality of the use of alcohol or other impairing substance does not constitute a defense against any charge of a “violation of subsection (1) of this section.” The use of the phrase “violation of subsection (1)” clearly shows that the elements of a DUI charge are wholly contained in subsection (1).

Further, KRS 189A.010(4) provides the various penalties for persons who “violate[] the provisions of subsection (1).” The penalties are then delineated,- the severity of punishment increasing with the number of violations of subsection (1). From the beginning, this Court has held that KRS 189A.010(4) “merely recognizes that one previously convicted of driving under the influence has the status of a prior offender, and can be penalized for having that status.” Commonwealth v. Ball, Ky., 691 S.W.2d 207, 209 (1985). Consequently, the Court of Appeals rebanee on the analysis in Clay was correct as subsection four (4) “is nothing more than a sentencing statute, with provision for enhancing the penalty for subsequent offenders.” Clay v. Commonwealth, Ky., 818 S.W.2d 264, 265 (1991). The prior DUI convictions are not elements necessary to determine guilt. Id.

The Commonwealth next asserts that the prior convictions are necessary to prove a felony as opposed to a misdemeanor. The importance of this determination, the Commonwealth maintains, is twofold. First, without introduction of the prior DUI’s, the Commonwealth will be limited to proving only a misdemeanor which is outside the Circuit Court’s jurisdiction. The Commonwealth has misconstrued the issue of jurisdiction. Once a defendant is indicted on a felony charge, the Circuit Court has jurisdiction. West v. Commonwealth, Ky., 887 S.W.2d 338 (1994); Nicholas v. Thomas, Ky., 382 S.W.2d 871 (1964). Secondly, the Commonwealth asserts that since the result, i.e. a conviction of DUI, wib net only a misdemeanor conviction the Circuit Court wib be left without authority to bifurcate the proceeding. Once a gubty verdict is reached, the Circuit Court has the authority to conduct a penalty phase, pursuant to KRS 532.055, in which the prior convictions may be introduced and the appropriate sentence determined, following proper instructions to the jury.

Given that the prior convictions are not essential to the Commonwealth’s case-in-chief in the prosecution of a DUI, the question becomes whether the introduction of the prior convictions during the guilt phase of the trial is unduly prejudicial to the defendant. The Commonwealth concedes, and we agree, that “unavoidable prejudice ... wbl result from the early introduction of evidence regarding a defendant’s previous convictions for drunk driving.” Ratliff, 719 S.W.2d at 449. The recognition of this prejudice is the foundation on which KRE 404(b)^[1] rests. This rule of evidence codified a long held, “well known fundamental rule that evidence that a defendant on trial committed other offenses is never admissible unless it comes within certain exceptions.” Jones v. Commonwealth, 303 Ky. 666, 198 S.W.2d 969, 970 (1947). Previous DUI convictions do not fall within either the exceptions outlined by KRE 404(b) or those recognized by this Court. See, Bell v. Commonwealth, Ky., 875 S.W.2d 882 (1994); McCarthy v. Commonwealth, [*529] Ky., 867 S.W.2d 469 (1993); and Rearick v. Commonwealth, Ky., 858 S.W.2d 185 (1993). As this Court has previously held:

Ultimate fairness mandates that an accused be tried only for the particular crime for which he is charged. An accused is entitled to be tried for one offense at a time, and evidence must be confined to that offense. The rule is based on the fundamental demands of justice and fair play.

O’Bryan v. Commonwealth, Ky., 634 S.W.2d 153, 156 (1982). Therefore, previous DUI convictions are not admissible during the guilt phase of a trial when offered to enhance the penalty.

In summary, we hold that KRS 189A.010(1) contains the elements of the crime of DUI. KRS 189A.010(4) is the penalty portion of the DUI statute and does not create additional crimes. Due to the prejudicial effect, prior DUI convictions shall not be introduced during the prosecution’s case-in-chief for a violation of KRS 189A.010(1).

For the foregoing reasons, the Court of Appeals is hereby affirmed.
