OPINION
Per Curiam:Respondents were arrested and convicted for drunk driving on multiple occasions. Respondent Paul was arrested on June 4, *4821985, March 17, 1988, and January 1, 1992, and was convicted of DUI under NRS 484.3791 on November 1, 1985, August 9, 1988, and May 6, 1993, respectively. Respondent Martinez was arrested on May 8, 1986, and March 3, 1993, and was convicted of DUI under NRS 484.379 on May 29, 1986, and November 22, 1993. After receiving the record of Paul’s third conviction and Martinez’s second conviction, the Department of Motor Vehicles (“DMV”) revoked Paul’s driver’s license for a period of three years pursuant to NRS 483.460(l)(a)(2) and Martinez’s driver’s license for a period of one year pursuant to NRS 483.460(l)(b)(5).2 On appeal, hearing officers upheld the license revocations. The district court subsequently granted respondents’ petitions for judicial review and reversed the revocation of respondents’ licenses. In its orders, the district court concluded that the revocations were improper because respondents’ convictions for their drunk driving offenses (on which their license revocations were based) did not fall within the seven-year period articulated in NRS 483.460. These appeals followed.
The DMV contends that the district court erred in concluding that the revocation of a driver’s license for drunk driving incidents within the seven-year period articulated in NRS 483.460(1) is based on the dates of the convictions, not upon the dates of the underlying violations of NRS 484.379. NRS 483.460(1) provides that upon receiving a record of a driver’s conviction, the DMV must revoke his or her driver’s license for a period of one year if *483the offense is “[a] second violation within 7 years of NRS 484.379,” and for a period of three years if the offense is “[a] third or subsequent violation within 7 years of NRS 484.379.” (Emphasis added.) Under the plain language of the statute, therefore, the revocation of a driver’s license is based on the number of drunk driving violations within seven years, regardless of the dates of the convictions for those violations. See Phipps v. State, 111 Nev. 1276, 1280, 903 P.2d 820, 823 (1995) (concluding that state must prove that prior offenses fall within seven-year period to enhance punishment for DUI under NRS 484.3792); Pfohlman v. State, 107 Nev. 552, 554, 816 P.2d 450, 450-51 (1991) (ruling that offenses, not convictions, must occur within seven-year period to enhance punishment under NRS 484.3792).
The purpose of NRS 483.460 is to protect the public from irresponsible drivers, not to reward drunk drivers for delayed convictions. Yohey v. State, Dep’t Motor Vehicles, 103 Nev. 584, 587, 747 P.2d 238, 240 (1987). In Yohey, we stated that one of the factors for revocation of a driver’s license for one year under NRS 483.460(l)(b)(5) was that the records received by the DMV show that the driver “was convicted twice within seven years.” Id. at 586, 747 P.2d at 239 (emphasis added). It appears, therefore, that the district court was understandably misled by our language in that opinion. Although we implicitly recognized in Yohey that violations of NRS 484.379 do not give rise to license revocation unless they result in convictions, Yohey did not address the issue presented in these appeals or whether the seven-year period articulated in NRS 483.460 is measured by the dates of the offenses or the dates of the subsequent convictions. Instead, Yohey resolved the issue of whether a justice’s court’s treatment of a second conviction as a first offense was binding on the DMV in a subsequent administrative revocation proceeding. Accordingly, our discussion in Yohey was not intended to prevail over the plain language of NRS 483.460(1) and is not dispositive of the issue raised in these appeals.
We conclude that the revocation of a driver’s license pursuant to NRS 483.460(1) is based on the dates of a driver’s violations of NRS 484.379 within a seven-year period, not upon the dates of the resulting convictions. Thus, we conclude that the district court erred in granting respondents’ petitions and reversing the revocations of their drivers’ licenses. Accordingly, we reverse the orders granting respondents’ petitions and remand these cases to the district court with instructions to reinstate the administrative revocation of respondents’ drivers’ licenses pursuant to NRS 483.460(l)(a)(2) and (l)(b)(5).
