OPINION
BEN H. CANTRELL, Special Justice.This Court granted a Rule 11 application under the Tennessee Rules of Appellate Procedure to determine whether the defendants’ sentences expired when the sheriff could not incarcerate them due to an overcrowded jail. The Court of Criminal Appeals affirmed the trial court’s holding that the sentences did not begin to run until the defendants were actually taken into custody. We reverse and hold that under the circumstances of these cases the sentences began to run when they became final and have, in fact, expired.
I.
On August 27, 1990 in the City Court of Jackson, defendant Walker entered a guilty plea to the offense of driving under the influence and received a jail sentence of eleven months and twenty nine days. All but twenty days were suspended. The order entered in the City Court contained the following:
MITTIMUS TO JAIL AFTER VERDICT: To the jailer of Madison County: The Judgment contained herein having been Entered, you are, therefore, commanded to receive the Defendant into your custody and detain him until he is legally discharged.
The next day when the defendant reported to the Madison County Sheriffs Office to begin serving his sentence, he was told that there was no space available and that he would be notified when to report. Nearly two years later, on July 27, 1992, he got the notice to report to jail. The record reflects that the Madison County jail was under a federal court order limiting the number of prisoners that could be incarcerated at any one time.
On August 26,1991, in the Circuit Court of Madison County, defendant Love pled guilty to the charge of driving under the influence. He received the same sentence as Walker, and although the judgment did not specify when he was to start serving the sentence, he reported immediately to the Sheriff’s Office. Love was told that the jail was overcrowded and that he would be notified when to report. On August 11, 1992 he was notified to report to jail on September 28, 1992.
Both defendants filed petitions for post-conviction relief which the trial judge treated as petitions for habeas corpus. The Circuit Court denied any relief and the Court of Criminal Appeals affirmed, holding that a sentence begins to run on the day a defendant legally comes into the custody of the sheriff under the judgment of imprisonment. Thus, the mere expiration of time without confinement, according to the Court of Criminal Appeals, is not an execution of the criminal judgment.

The effect of an inordinate delay in the execution of a criminal judgment has been frequently litigated in other courts. See Annotation, Effect of Delay in Taking Defendant into Custody after Conviction and Sentence, 98 A.L.R.2d 687 (1964). Even where the delay results from simple negligence or oversight, the courts have recognized that relief from the sentence might be available on due process grounds. See United States v. Martinez, 837 F.2d 861 (9th Cir.1988); Mobley v. Dugger, 823 F.2d 1495 (11th Cir.1987). In both of these cases the courts also analyzed the claims on the basis of waiver or estoppel but refused relief on any basis because of the high standard that must be met before relief is available. (The State’s action *556“must be so affirmatively wrong or its inaction so grossly negligent that it would be unequivocally inconsistent with ‘fundamental principles of liberty and justice’ to require a legal sentence to be served in the aftermath of such action or inaction.” Mobley at 1496-97.) Cf. State v. Roberts, 568 So.2d 1017 (La.1990).
Another doctrine called “credit for time at liberty” has been invoked where the defendant has been incarcerated under a criminal judgment but erroneously released through no fault of his own. Under those circumstances the courts hold that his sentence continues to run while he is at liberty. See Green v. Christiansen, 732 F.2d 1397 (9th Cir.1984); Smith v. Swope, 91 F.2d 260 (9th Cir.1937). We know of no instance, however, where this doctrine has been applied to a situation where no time at all has been served. See United States v. Martinez, 837 F.2d 861 (9th Cir.1988).
In other eases, most of them in the state courts, where the defendant has presented himself for incarceration and has been refused admission for some reason (an overcrowded jail or simple inaction on the part of the jailer) the courts have said that the sentence began to run when the defendant did all that was required of him to allow the imposition of the criminal sentence. State v. Riske, 448 N.W.2d 260 (Wis.App.1989); Maxwell v. State, 188 Ga.App. 862, 374 S.E.2d 800 (1988); Huff v. McLarty, 241 Ga. 442, 246 S.E.2d 302 (1978); Carter v. State, 339 So.2d 594 (Ala.App.1976).
III.
The lack of in depth analysis in some of the state cases — particularly the part played by state statutes — persuades us that there is no uniform constitutional standard that has been applied in cases where a defendant is refused admission to the jail because of overcrowded conditions. We cannot say that under those conditions the State’s action is so affirmatively wrong or grossly negligent that further incarceration would be inconsistent with fundamental principles of liberty and justice. We will, therefore, examine the question based on our own statutes.
There are three statutes that bear on the questions raised here. The first, Tenn.Code Ann. § 40-23-103 provides:
It is the duty of the sheriff in whose custody the defendant is at the rendition of the judgment, or afterwards legally comes, to execute the judgment of imprisonment by committing the defendant, as soon as possible, to jail, or to the warden of the penitentiary, according to the exigency of the writ.
The next, although first in order in the Code, is Tenn.Code Ann. § 40-23-101, the pertinent parts of which provide:
(a) Hereafter, when a person is sentenced to imprisonment, the judgment of the court shall be rendered so that such sentence shall commence on the day on which the defendant legally comes into the custody of the sheriff for execution of the judgment of imprisonment.

(2) This section shall not interfere with the operation of the statute requiring sheriffs in whose custody-defendants come for execution of judgments of imprisonment to commit such defendants as soon as possible to jail or to the warden of the penitentiary.
The third statute appears in title 41, chapter 4 of the Code dealing with the powers and responsibilities of sheriffs or jailers in general. Section 121 of that chapter provides:
(a) The sheriff has authority, when the jail of his county is insufficient for the safekeeping of a prisoner, to convey him to the nearest sufficient jail in the state.
The first two statutes indicate a legislative intent that the sheriff shall commit a defendant to jail as soon as possible after the rendition of the judgment and that a judgment requiring incarceration should specifically provide that the sentence begins to run “on the day on which the defendant legally comes into the custody of the sheriff for execution of the judgment of imprisonment.” We do not think the statutes conflict since subsection (a)(2) of Tenn.Code Ann. § 40-23-101 specifically provides that it will not interfere with Tenn.Code Ann. § 40-23-103.
*557The State argues that since the Madison County jail was under a federal court order limiting the number of prisoners that could be confined there at any one time, it was not possible for the sheriff to commit the defendants until they were ordered to report. Therefore, the sentences did not begin to run and have not expired.
But what of Tenn.Code Ann. § 41-4-121 allowing a sheriff to convey prisoners to the nearest jail “sufficient” for their safekeeping? The term “prisoner” as used in this section refers to persons sentenced to imprisonment in the county jail. Tenn.Code Ann. § 41-4-103. We are also convinced that an “insufficient” jail includes one that is so overcrowded that it violates the prisoner’s rights under the Eighth amendment to the United States Constitution. It is arguable, of course, that the statute refers only to the sufficiency of the jail to keep prisoners under lock and key; i.e. to prevent an escape. But the statute uses broad terms, “insufficient” and “safekeeping of a prisoner”, which we think cover more than just the prevention of an escape. Cf. State v. Grey, 602 S.W.2d 259 (Tenn.Crim.App.1980).
Recognizing the authority of a sheriff under this code section, it could hardly be argued that the sheriff in this case committed the appellants to jail as soon as possible. There is no proof in the record of any attempt to find the “nearest sufficient jail” for their safekeeping.
What is the remedy for persons sentenced to jail who have presented themselves to the proper authorities for incarceration and have been denied their request to begin serving their sentences immediately? We are persuaded that our statutes require more than a passive course of non-action that leaves such persons living indefinitely under an unexecuted criminal sentence. Therefore, we hold that where persons under a criminal sentence immediately present themselves to the appropriate authorities for incarceration and are turned away the sentence in each case shall begin to run when the judgment of conviction becomes final or the prisoner is actually incarcerated, whichever is earlier.
We are dealing with two related societal problems, drunk drivers and overcrowded jails. Responding to a public outcry over the huge losses—in human lives and property damage—caused by drunk drivers, the legislature made incarceration mandatory, even for the first offense. Few would disagree with the proposition that people who operate vehicles in an impaired state deserve to be punished severely.
Such punishment, however, has its costs. Longer, mandatory sentences inevitably lead to overcrowded jails, and building more jails severely impacts the public treasury. But the drunk driving problem cannot be addressed in a vacuum. If drunk drivers are to be punished by incarceration the public must stand ready to provide the facilities in which the sentence may be served. Otherwise, the law books will be filled with criminal sanctions having absolutely no meaning and drunk drivers will remain free to endanger the public without the deterrent effect of punishment. A criminal conviction involving a period of incarceration presumes that there is a place where the sentence can be carried out.
Although we are convinced that the sentences imposed on the defendants in these cases have expired, we are also persuaded that the rule announced today should be prospective only and should apply only to cases tried or retried after the date of this opinion and cases on appeal in which the issue has already been raised.1
The judgments of the Court of Criminal Appeals and the Circuit Court of Madison County are reversed and the sentences imposed on the appellants are dismissed. Tax the costs on appeal to the State.
ANDERSON, C.J., and DROWOTA and REID, JJ., concur. WILLIAM H.D. FONES, Special Justice, dissents.. We note that the legislature passed and the governor signed Public Chapter No. 524 of the Acts of 1995 which may affect the rule we announce today. We express no opinion about what effect the statute may have because that issue is not before us.
