delivered the opinion of the court:
Defendant, Lois L. Wilhelm, was arrested and charged by information with driving under the influence of alcohol (625 ILCS 5/11— 501(a)(2) (West 2002)) and driving with a breath-alcohol concentration of 0.08 or more (625 ILCS 5/11 — 501(a)(1) (West 2002)). She was also given notice that her driving privileges were summarily suspended under section 11 — 501.1 of the Illinois Vehicle Code (625 ILCS 5/11— 501.1 (West 2002)). She filed a petition to rescind the summary suspension, which the trial court granted. The State appeals, arguing that the court erred in construing the regulations for the administration of the breath test. We reverse.
Section 1286.310 of the Illinois Administrative Code (the Code) (20 Ill. Adm. Code § 1286.310 (2003)) describes the procedures for obtaining an individual’s breath sample to determine his or her breath-alcohol concentration. The first step requires a 20-minute observation period before an officer administers the test, during which the individual may not have had alcohol or any foreign substance in his or her mouth. 20 Ill. Adm. Code § 1286.310(a)(1) (2003). This requirement relates to the reliability of the breath test because foreign substances like food, smoke, or water may alter the breath-alcohol content. People v. Miller,
In this case, at the hearing on defendant’s petition to rescind the statutory summary suspension, the parties stipulated to the following.
After the arresting officer continuously observed her for 20 minutes, defendant was given a breath test. The instrument used to take the breath sample, the Intox EC/IR, a Department of State Police approved breath test instrument (20 Ill. Adm. Code § 1286.210(a)(2) (2003)), consisted of an analysis device connected by a breath tube to a mouthpiece. As instructed, defendant put the mouthpiece into her mouth and blew into it. That blow did not produce a sufficient sample for the breathalyzer to analyze. Defendant removed the mouthpiece, spoke to the officer, replaced the mouthpiece, and blew again. That blow also did not produce a sufficient breath sample. Again, she removed the mouthpiece, replaced it, and blew. The third blow produced a sufficient breath sample. The breathalyzer reading indicated that defendant had a breath-alcohol content above 0.08. Defendant’s three attempts to give a breath sample took approximately four minutes, as the breathalyzer took about one minute to recycle and prepare for each test.
After the stipulated facts were presented, the court took the matter under advisement. In its written order, the court concluded that the State did not follow the rules for administering the breath test. It determined that the breathalyzer’s mouthpiece was a “foreign substance,” as defined by section 1286.10 of the Code (20 Ill. Adm. Code § 1286.10 (2003)). As such, the Code mandated that, once the foreign substance had entered defendant’s body, a new 20-minute observation period was required before the next breath test could be administered. The court rescinded defendant’s summary suspension. The State appeals.
The only issue on appeal is whether the trial court erred in its interpretation of the Code. Administrative rules and regulations have the force of law and must be construed under the same standards that govern the construction of statutes. Northern Illinois Automobile Wreckers & Rebuilders Ass’n v. Dixon,
Specifically, the Code states, “During the 20[-]minute observation period the subject shall be deprived of alcohol and foreign substances and shall not have regurgitated or vomited.” 20 Ill. Adm. Code § 1286.310(a)(1) (2003). The Code further defines a foreign substance as “any substance not in the subject’s body when a 20-minute observation period is commenced, excluding a substance introduced due to normal breathing.” 20 Ill. Adm. Code § 1286.10 (2003). The trial court interpreted the phrase “foreign substance” in section 1286.10 of the Code as including the breathalyzer’s mouthpiece. The State argues that if the breathalyzer’s mouthpiece is considered a “foreign substance,” then a second breath test can never be performed. Under such a reading of the Code, once the mouthpiece enters an individual’s mouth so that a breath sample can be obtained, a new observation period is required because a foreign substance has entered the subject’s body. We find the language in question unclear; thus, the language is ambiguous.
When' a regulation is ambiguous, we may look beyond the language as written to discern the drafters’ intent and consider the purpose of the regulation and the evils that it was designed to remedy. In re B.C.,
Because the obvious purpose of the regulation is to perform reliable breath tests, we cannot agree with the trial court’s conclusion that the breathalyzer’s mouthpiece is a “foreign substance” under the Code. In addition to the Code’s purpose, we find support for this resolution in Washington’s breath test administration regulations. In that state, the procedures for performing an accurate breath test are as follows:
“The following method for performing a breath test is approved by the state toxicologist *** and includes the following safeguards to be observed by the operator prior to the test being performed. It must be determined that: (1) The person does not vomit or have anything to eat, drink, or smoke for at least fifteen minutes prior to administration of the test; and (2) the subject does not have any foreign substances, not to include dental work, fixed or removable, in his or her mouth at the beginning of the fifteen minute observation period. Such determination shall be made by either an examination of the mouth or a denial by the person that he or she has any foreign substances in mouth. A test mouthpiece is not to be considered a foreign substance for purposes of this section.” (Emphasis added.) Wash. Adm. Code § 448 — 13—040 (2003).
Obviously, the drafters of section 448 — 13—040 of the Washington Administrative Code (Wash. Adm. Code § 448 — 13—040 (2003)) have already considered the present issue — whether a breathalyzer?s mouthpiece is a foreign substance that, if it enters a subject’s mouth, requires a new observation period to ensure the test’s accuracy. In a regulation very similar to our own, the Washington drafters expressly excluded a breathalyzer’s mouthpiece from the definition of a foreign substance. Wash. Adm. Code § 448 — 13—040 (2003). Likewise, we hold that the Code drafters intended for the phrase “foreign substance” in section 1286.310 of the Code (20 Ill. Adm. Code § 1286.310 (2003)) to exclude a breathalyzer’s mouthpiece. Accordingly, we further hold that the trial court’s decision to grant defendant’s petition to rescind the statutory summary suspension was erroneous.
The judgment of the circuit court of Lee County is reversed and the cause remanded.
Reversed and remanded.
GROMETER and BYRNE, JJ., concur.
