[¶ 1] Scott Thomas Mund entered a conditional guilty plea to driving under the influence and was sentenced under Rule 11(a)(2), N.D.R.Crim.P. Mund appeals from the conviction entered on August 19, 1998.
I
[¶2.] In March 1998, Mund was charged with driving under the influence (DUI). Mund had previously, without counsel, pleaded guilty to DUI in August 1997. Mund moved to certify the 1998 offense as a first offense and to withdraw his guilty plea from the prior 1997 DUI conviction. On June 24, 1998, a hearing on the motion was held. At the hearing, portions of an audio tape from the August 1997 court proceeding were played. The trial court denied Mund’s motion, finding the court had complied with Rule 11, N.D.R.Crim.P., during the August 1997 proceeding. Mund entered a conditional plea of guilty to the charge and appealed, arguing his guilty plea in the August 1997 DUI conviction should be withdrawn or suppressed. Specifically, Mund argues the trial court did not follow the requirements of Rule 11(b), N.D.R.Crim.P., in the 1997 criminal proceeding; there was not a sufficient factual basis made for the uncounseled 1997 guilty plea under Rule 11(e), N.D.R.Crim.P.; and the trial court did not comply with Rule 11(c), N.D.R.Crim.P., by failing to inform him of the direct consequences of his uncoun-seled 1997 guilty plea because he was not told his conviction could be used as enhancement in subsequent criminal proceedings.
[¶ 3] The State asserts Mund should have raised the issues relating to the 1997 guilty plea under N.D.C.C. ch. 29-32.1, the Uniform Post-Conviction Procedure Act, or at the time of that conviction. In effect, the State contends Mund’s arguments relating to the 1997 conviction are an improper collateral attack on his prior guilty plea, which is being used as penalty enhancement in the current criminal proceeding.

[¶ 4] Mund is unable to prevail in his Rule 11, N.D.R.Crim.P., arguments because they are impermissible collateral attacks on the prior 1997 guilty plea. 1

[¶ 5] In
State v. Orr,
[¶ 6] The United States Supreme Court has since addressed collateral attacks on guilty pleas and convictions when they are used as enhancement in subsequent convictions. In
Custis v. United States,
[¶ 7] The Supreme Court first held section 924(e) of the ACCA did not give defendants the right to collaterally attack prior convictions that were being used for enhancement purposes in a subsequent criminal proceeding.

[¶ 8]
Custis
is helpful in defining the limits of collateral attack on prior convictions that are being used as penalty enhancement in a subsequent criminal proceeding. The United States Supreme Court places a priority on the right to counsel, similar to the protections our state Constitution provides. In reaching its decision in
Custis,
the Supreme Court pointed to
Burgett
and
Tucker
as cases indicating a theme that failure to appoint counsel was a unique constitutional defect.
Id.
at 496,
[¶ 9] In analyzing Custis’s argument, the Supreme Court found a historical basis for treating the right to counsel as unique, noting its “oft stated view that ‘the right to be heard would be, in many cases, of little avail if it did not comprehend the right to be heard by counsel.’ ”
Id.
at 494-95,
[¶ 10] We hold that when prior guilty pleas are offered for enhancement purposes in subsequent criminal proceedings, collateral attacks on such prior guilty pleas are limited to the inquiry Orr requires to determine a *762 valid waiver of the right to counsel. This is in agreement with the requirements of the United States Constitution, and North Dakota’s strong independent notion of right to counsel under the North Dakota Constitution is in no way eroded by our holding today.
[¶ 11] In this case, Mund stipulated during the motion to suppress that he had signed the waiver of attorney form when he pleaded guilty in the August 1997 proceeding. Mund has not provided any reason why his waiver of right to counsel was deficient. The Orr inquiry regarding a valid waiver of defendant’s right to counsel is therefore satisfied, and we hold Mund’s prior uncounseled guilty plea can be used as enhancement for the subsequent DUI offense.
Ill
[¶ 12] We affirm the trial court’s decision not to suppress the prior guilty plea for the reasons stated above.
