   OPINION

PER CURIAM.

A magistrate judge found Gregory Rose guilty of reckless driving pursuant to 36 C.F.R. § 4.2 (2002) (assimilating Va.Code Ann. § 46.2-852 (2002)). The district court affirmed the magistrate judge’s judgment. On appeal, Rose contends: (1) the magistrate judge did not have jurisdiction; (2) the prosecution improperly withheld exculpatory and impeachment evidence; (3) the magistrate judge denied him the right to confront witnesses against him; and (4) the magistrate judge abused his discretion in granting a fifty-six day continuance. Rose also contends the cumulative effect of the errors violated his right to due process and equal protection. Finding no error, we affirm.

First, Rose waived review with regard to any alleged error concerning the notice of violation that was unsigned and unverified. See Fed.R.Crim.P. 12(b)(2); United States v. Williams, 89 F.3d 165, 167 n. 1 (4th Cir.1996). Moreover, the regulation under which Rose was convicted had the force and effect of law. See United States v. Fox, 60 F.3d 181, 184 (4th Cir.1995). Because Rose did not face a sentence longer than six months’ imprisonment, the magistrate judge had jurisdiction to hear the case without a jury. See Fed. R.Crim.P. 58(b)(2)(E)(i); Lewis v. United States, 518 U.S. 322, 325-27, 116 S.Ct. 2163,135 L.Ed.2d 590 (1996).

Second, the Government did not improperly withhold any exculpatory or impeachment evidence. Nor did the Government fail to fulfill its obligation under Jencks v. United States, 353 U.S. 657, 667-72, 77 S.Ct. 1007, 1 L.Ed.2d 1103 (1957), and the Jencks Act, 18 U.S.C. § 3500 (2000).

Third, the magistrate judge did not abuse his discretion in admitting the tape recording of a telephone call and did not violate Rose’s right to confront witnesses against him. United States v. Bostian, 59 F.3d 474, 480 (4th Cir.1995) (stating standard of review). Nor did the magistrate judge abuse his discretion in continuing the trial for approximately fifty-eight days. United States v. Sampson, 140 F.3d 585, 591 (4th Cir.1998). Finally, given that the magistrate judge did not err, Rose’s claim that the cumulative effect of the errors denied him his due process and equal protection rights is without merit.

We affirm the conviction and sentence. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

AFFIRMED.
