OPINION
KALITOWSKI, Judge.This pretrial appeal is from an order suppressing a blood test. We reverse.
FACTS
Respondent Corrine Ault was stopped on March 24, 1991, when officers observed her traveling in the wrong lane of traffic. The arresting officer observed indicia of intoxication, and, when asked, Ault admitted she had been drinking. Ault was arrested and taken to the Law Enforcement Center, where she was given the implied consent advisory and agreed to take a blood test. As part of the advisory, Ault was told she had a right to consult an attorney after submitting to testing. She stated she understood this.
The blood test showed an alcohol concentration of .11. Ault was charged with misdemeanor DWI and illegal lane usage. Ault made no written pretrial motions. On July 2, 1991, the day the case was scheduled to be tried, Ault made an oral motion, without prior notice, to suppress the blood test and dismiss the complaint. Ault argued she had not been given an opportunity to consult with counsel before being asked to submit to testing, a right announced in Friedman v. Commissioner of Pub. Safety, 473 N.W.2d 828, 833 (Minn.1991).
The state objected that the suppression motion was untimely. The court, however, permitted the motion and suppressed the test because Ault’s right to counsel, as announced in Friedman, had been violated.
ISSUES
1. Would suppression of the test have a critical impact on the DWI prosecution?
*7992. Did the trial court clearly err in applying the Friedman holding?
ANALYSIS
I.
The state in a pretrial appeal has the burden of showing clearly and unequivocally that the trial court erred in its judgment and that, unless reversed, the error will have a critical impact on the outcome of the prosecution. State v. Webber, 262 N.W.2d 157, 159 (Minn.1977). “Critical impact” is shown “where the lack of the suppressed evidence significantly reduces the likelihood of a successful prosecution.” State v. Joon Kyu Kim, 398 N.W.2d 544, 551 (Minn.1987).
The supreme court has held that a defendant’s confession may have a “critical impact” even though the state has other substantial evidence of guilt. State v. Ronnebaum, 449 N.W.2d 722, 724 (Minn.1990). A chemical test showing an alcohol level in excess of the statutory limit is evidence of similar probative value in a DWI prosecution. See State v. Wickern, 411 N.W.2d 597, 598-99 (Minn.App.1987). We conclude that in this case the state has shown suppression of the test will have a “critical impact.”
II.
Under the Minnesota Constitution a driver possesses a right to an opportunity to consult with counsel before being asked to submit to chemical testing. Friedman v. Commissioner of Pub. Safety, 473 N.W.2d 828, 833 (Minn.1991). The supreme court, however, has limited the retroactive application of this holding:
Friedman thus applies retroactively only to cases pending on the date of the Friedman decision where the driver properly and in a timely fashion requested an opportunity to consult with an attorney, the request was denied, and the driver properly challenged the denial in district court as a violation of the right to counsel under the Minnesota Constitution * * *. Only if the issue of right to counsel under the Minnesota Constitution had actually been raised in district court prior to June 7, 1991, will Friedman apply retroactively.
Id. at 838 (on petition for rehearing). The trial court did not have the benefit of this clarification.
There is no indication in the record that Ault requested an opportunity to contact counsel, the first condition for applying Friedman. Ault does not contend on appeal that she did so, and her responses at the time the advisory was given make it unlikely she did. Therefore, the Friedman holding does not apply to this prosecution.
DECISION
The trial court clearly erred in applying Friedman to this prosecution. The state has shown the suppression order would have a “critical impact” on the prosecution.
Reversed.
