NATURE OF CASE
In this сase, the Nebraska Department of Motor Vehicles (department) appeals from an order of the district court for Douglas County. After an administrative license revocation hearing, the department concluded that Michael C. Morrissey had refused to submit to a chemical test of his breath. In part on this basis, the deрartment revoked Morrissey’s driver’s license. The district court reversed, relying on
Keys
v.
Department of Motor Vehicles,
BACKGROUND
On May 21, 2000, Officer Kenneth Randall of the Omaha Police Department was dispatched to the scene of a car accident on 60th Street near Interstate 80 in Omaha, Nebraska. At the scene, Randall discovered Morrissey behind the wheel of a vehicle situated on the median on 60th Street. Upon approaching the vehicle, Randall detected a strong odor оf alcohol coming from Morrissey and the vehicle. Randall also observed that Morrissey had bloodshot eyes and appeared to be extremely intoxicated and sleepy. Randall attempted to administer a field sobriety test; however, Morrissey’s condition prevented him from completing the test. Morrissey also failеd a preliminary breath test at the scene.
Morrissey was arrested and transported to police headquarters. At the police station, Morrissey was read a postarrest chemical test advisement form and he agreed to submit to the chemical test. The chemical test was conducted by an analyst in the presеnce of two Omaha police officers, including Randall. Morrissey placed the mouthpiece of the Intoxilyzer 5000 in his mouth and blew a “small” sample into the machine. The test record card indicated that Morrissey had an alcohol content of 0.203 grams of alcohol per 210 liters of breath. However, the test record сard *458 also indicated that the sample of breath obtained from Morrissey was deficient. Morrissey was told that he needed to repeat the test to produce a sufficient sample. Morrissey refused to submit to any further chemical test. Randall completed a “Notice/Swom Report/Temporary License” (sworn reрort) and provided a copy to Morrissey. The sworn report indicates that Morrissey was requested to submit to a chemical test and that he “refused to submit to a chemical test or tests of breath, blood or urine.”
Morrissey petitioned for a hearing to contest the revocation of his drivers’ license. At the hearing, testimony was received from Randall and exhibits were received into evidence, including the sworn report. Also received into evidence was a copy of the test record card and the chemical test checklist. The checklist set forth the steps to be followed when administering a chemical test using an Intoxilyzer 5000. One of the steps stated: “SUBJECT DIGITAL READING: 0._of a gram of alcohol per 210 liters of breath.” Handwritten in the blank space of that step was the number “.203.”
Following the license revocation hearing, the department entered an order revoking Morrissey’s driver’s license for 1 year. As a basis for revocation, the department found in part that Morrissey had refused to submit to a chemical test. Morrissey appealed the order of revocation to the district court. The court reversed, finding that pursuant to
Keys v. Department of Motor Vehicles,
ASSIGNMENTS OF ERROR
The department assigns that the district court erred in (1) reversing the decision of the director of the department and reinstating Morrissey’s driver’s license and (2) finding that Morrissey had submitted to and completed a valid chemical test pursuant to Neb. Rev. Stat. § 60-6,205 (Reissue 1998).
STANDARD OF REVIEW
Decisions of the director of the Department of Motor Vehicles, pursuant to Nebraska’s administrаtive revocation statutes, are appealed under the Administrative Procedure Act (APA).
*459
Reiter v. Wimes,
A judgment or final order entered by a district court in a judicial review pursuant to the APA may be reversed, vacated, or modified by an appellate court for errors appearing on the record.
Davis v. Wimes,
An appellate court, in reviewing a district court’s judgment for errors appearing on the record, will not substitutе its factual findings for those of the district court where competent evidence supports those findings. Reiter v. Wimes, supra.
Whether a decision conforms to the law is by definition a question of law, in connection with which an appellate court reaches a conclusion independent of that reached by the lower court. Id.
Interpretаtion of statutes presents a question of law, and an appellate court is obligated to reach an independent conclusion, irrespective of the decision made by the court below, with deference to an agency’s interpretation of its own regulations, unless plainly erroneous or inconsistent. Davis v. Wimes, supra.
ANALYSIS
The fundamental issue in this appeal is whether the evidence offered by the department established that Morrissey refused to provide a sufficient sample of breath. As a general rule, the offer by the department of the sworn report at the hearing establishes the department’s prima facie case and the burden shifts to the driver tо refute such evidence.

v.

In its argument to this court, the department places considerable emphasis on the Nebraska Department of Health and Human Services Regulation and Licensure’s rules and regulations, 177 Neb. Admin. Code, сh. 1 (1998), which we take judicial notice of. See

We deem this violation of § 002.01A to be significant. We have previously held that to be valid, an action of an agency must conform to its rules which are in effect at the time the action is taken.

v.
State,
In

v.
Conrad, supra,
we held that the department makes a prima fаcie case for revocation once they establish the officer provided his or her sworn report containing the required recitations. The burden then shifts to the defendant to prove that one or more of the recitations in the sworn report are false. See, also,
Davis
v.
Wimes,
The rule expressed in
McPherrin
v.
Conrad,
The sworn report received at Morrissey’s license revocation hearing recited, inter alia, that Morrissey refused to submit to a chemical test of his breath, blood, or urine. While we determine that this fact may not be presumed to be true, the question now becomes whether the department offered sufficient evidence of Mоrrissey’s refusal, independent of the sworn report.
At Morrissey’s license revocation hearing, Randall testified that he transported Morrissey to police headquarters for chemical testing and was present during Morrissey’s chemical test. Randall described the administration of the chemical test as follows:
Q Did he — did Mr. Morrissey, did he take the mouth piece into his mouth?
A Yes he did. He refused to blow an adequate sample.
Q Did he offer some air into the instrument? I mean — A Yes, I believe he did some.
Q Did he, at any point, verbally refuse?
A Yes, he did.
*462 Q What — okay, what happened? Just explain to me what happened.
A For the test, he sat down, Mr. Ingram explained the test, he did put the mouth piece to his mouth, then he got angry. He did — I believe he did blow a small amount at one point, and Mr. Ingram explained he needs to blow long and hard through the tube, and he verbalized that he wasn’t going to do it, after a small period of time.
Q And did, at any — after he said he was not going to do it, did he offer any air into the instrument after that point?
A No, he didn’t.
Morrissey argues that the district court correctly applied
Keys
v.
Department of Motor
Vehicles,
On appeal, we were asked to decide if the motorist had submitted to a chemicаl breath test as required by Nebraska law under these facts. We noted that “[o]ur [driving under the influence] and administrative license revocation statutes are silent on whether the results of a chemical breath test must be shown on a test record card in order to be legally sufficient, or whether a digital Intoxilyzer reading will suffice.”
Id.
at 968,
a motorist who provides a sufficient sample of breath to register a digital reading on an Intoxilyzer, but who does not provide enough breath to cause the machine to print the result on a test record card, has submitted to a breath test as required by Nebraska law in the absence of any statutory or regulatory requirement that the results be printed on a test record card ....
Keys v. Department of Motor Vehicles,
The department now argues that Keys is no longer controlling in light of revisions to 177 Neb. Admin. Code, ch. 1, promulgated subsequent to, and purportedly in response to, Keys. The department asserts that under these rules and regulations, Morrissey’s failure to provide a sufficient sample of breath constituted a refusal to submit to a chemical test of his breath.
The Department of Health and Human Services Regulation and Licensure defines refusal as “the failurе to provide a sufficient sample of body fluid to complete a blood, breath, or urine test or the refusal to submit to a chemical test of blood, breath, or urine.” 177 Neb. Admin. Code, ch. 1, § 001.19 (1998). (Emphasis supplied.) Section 002.01A states in part: “[An] insufficient sample does not constitute a valid test.” “Valid test” is defined as “an analysis performed according to methods approved by The Department of Health and Human Services Regulation and Licensure and by an individual possessing a valid permit.” 177 Neb. Admin. Code, ch. 1, § 001.15 (1998).
Generally, a legislative enactment may properly confer general powers upon an administrative agency and delegate to the agency the power to make rules and regulations concerning the details of the legislative purpose.
Creighton St. Joseph Hosp. v. Tax Eq. & Rev. Comm.,
*464
The Legislature has conferred power to the Department of Health and Human Services Regulation and Licensure to adopt methods for determining whether chemical tests may be considered valid. Neb. Rev. Stat. § 60-6,201(3) (Reissue 1998). The rules and regulations cited above indicate that a motorist who fails to provide a sufficient sample of breath, regardless of the digital reading produced by that insufficient sample, has rеfused to submit to a chemical test. Those rules and regulations also indicate that a valid test has not been conducted when an insufficient sample of breath has been provided. In this case, Randall testified that Morrissey offered a “small,” but inadequate, sample of breath into the Intoxilyzer. Morrissey was then instructed to repeat the process in order to obtain an adequate sample of breath; however, Morrissey refused, and no adequate sample of breath was ever received from him. Under the above-cited rules and regulations, Morrissey is deemed to have refused to submit to a chemical test. To the extent that it conflicts with these rules and regulations,
Keys
v.
Department of Motor Vehicles,
CONCLUSION
Where the department fails to strictly comply with 177 Neb. Admin. Code, ch. 1, it cannot obtain the benefit of a presumption that all facts recited in a sworn report are true. Instead, the department must offer sufficient evidence, independent of the sworn report, to establish that a motorist’s driver’s license should be rеvoked. In this case, the department offered sufficient evidence, independent of the sworn report, to establish that Morrissey refused to submit to a chemical test of his breath under the Nebraska Department of Health and Human Services Regulation and Licensure’s rules and regulations. These rules and regulations, which have the еffect of statutory law, indicate that Morrissey’s failure to provide a sufficient sample of breath during a chemical test constitutes a failure to submit to a chemical test. These rules and regulations supersede our decision in
Keys
v.
Department of Motor Vehicles,
Reversed and remanded with directions.
