ALMA WILSON, Justice:

On September 5, 1991, the Department of Public Safety, appellant, revoked the driving privileges of Michael L. Baldwin, the appellee, for a period of one year pursuant to the Implied Consent Law. The appellee had refused to take a test to determine the alcohol content of his breath. The appellee appealed his revocation to the district court. The district court vacated the order of the appellant and restored the appellee's drivers license. The Court of Appeals reversed and remanded with instructions to deny the appellee's petition. Certiorari was granted to decide whether the blood or breath test has been refused if a motorist initially declines the test but reconsiders and asks to take the test shortly thereafter. We hold that the motorist has not refused the test if the assent is timely and given unequivocally.

The following facts are taken from the findings of facts by the trial judge. On July 17, 1991, in Lincoln County, an Oklahoma Highway Patrol trooper made a valid probable cause stop and arrest of the appellee. The stop was made about eighteen miles from the Lincoln County Sheriff's office. The trooper asked the appellee to take a breathalyzer or blood test to determine the alcohol level in the appellee's blood. The appellee asked to speak to a lawyer, but the trooper responded that no such right existed relative to his consent or refusal to take the test. The appellant then refused the test. He was readvised of his rights under the Implied Consent Law and again refused. The trooper took him to the Lincoln County Sheriff's office.

Upon their arrival, before the appellee was placed in a cell and before the arresting officer filled out the "Officers Affidavit and Notice of Revocation" the appellee told the trooper that he wished to take the breathalyzer test. The trooper replied that the appellee was too late and refused to administer the test. The officer then completed his affidavit required by 47 O.S. 1991 § 754[ 47-754]. The trial court found that the appellee offered to take the test almost immediately after being transported to the location of the breathalyzer machine. He further found that the officer was neither delayed in performing his duties nor required to wait to determine if the appellee would change his mind.

The trial transcript reveals that the time between the appellee's initial refusal and his subsequent recantation was between five and ten minutes. The officer testified that if the test had been administered when the appellee requested it, the test would have remained valid. He testified that other than the policy of not administering the test after a refusal, the test could have been administered. The appellee was still in the custody of the arresting officer.

Title 47 O.S. 1991 § 753[ 47-753] provides in pertinent part:

If a conscious person under arrest refuses to submit to testing of his or her blood or breath for the purpose of determining the alcohol concentration thereof, or to a test of his or her blood, saliva or urine for the purpose of determining the concentration of any other intoxicating substance, or the combined influence of alcohol and any other intoxicating substance, none shall be given. . . .

The appellant argues that the statute is clear and unambiguous, that if a motorist refuses the test he cannot subsequently change his mind and be tested. The appellant asserts that even if the statute is ambiguous or uncertain, the interpretation by the agency, appellant, is entitled to the highest respect from the courts, especially when the administrative construction is definitely settled and uniformly applied for a number of years. But the issue before this Court involves the definition of the word "refusal" in § 753. The appellant essentially claims that once a motorist has spoken, he cannot recant. But in practice, as the trial court observed, the arresting officers give every motorist more than one opportunity to submit to testing. The facts before this Court make the issue one of first impression. The construction of this statute is within the jurisdiction of this Court. Despite the claims of the appellant to the contrary, the appellant has established by its own admission that the appellant does not clearly apply a certain construction to determine what acts of a motorist constitute a refusal to submit to testing. Additionally, in this and other jurisdictions, what constitutes a refusal is an issue determined by the appellate court system, and not by the administrating agency.

In Robertson v. State ex rel. Lester, 501 P.2d 1099 (Okla. 1972), Robertson was arrested for operating a motor vehicle upon the public highway while under the influence of alcohol. Immediately after the arrest, the officer asked that Robertson submit to a chemical test, either breath or blood, to determine the content of the alcohol in his blood. He refused and was denied the opportunity to consult with counsel before deciding whether or not to submit to the test. This Court held that the implied consent statute does not sanction a qualified or conditional refusal, so that unwillingness to submit to a test before consulting with counsel constitutes a refusal. The appellant has cited this case to support its position that a refusal is not negated by a subsequent request to take the test. The appellant quotes:

The decision to submit to a chemical test is not one which requires debate, consultation, or negotiation, but calls for a simple yes or no to the request for submission. Because of the rapidity with which the passage of time and the physiological processes tend to eliminate alcohol ingested by the body, and because of the remedial intent of the statute anything less than an unqualified consent by the licensee to the requested test constitutes a refusal to do so.

Robertson, 501 P.2d at 1104, emphasis provided by appellant. From this the appellant concludes that once a person refuses the test, the test cannot be given. However, the Oklahoma cases cited by the appellant to support its position do not involve refusal and subsequent timely recantation. As previously asserted, this issue is one of first impression in this jurisdiction. Robertson has been cited by the Supreme Court of Hawaii, among cases from four other jurisdictions, as holding that a refusal to submit to the test is binding where a motorist is offered the test, refuses or delays in consenting, but subsequently changes his mind and requests the test. State v. Moore, 62 Haw. 301, 614 P.2d 931, 935 (1980). Robertson does not so hold.

The Hawaii case involved a motorist arrested for driving under the influence of intoxicating liquor. That state also has an implied consent law, and pursuant to that law the motorist was advised of the requirements and sanctions of the law. The motorist refused to sign anything or take the test. After refusing to sign the Honolulu Police Department's Implied Consent Form, the motorist testified that he demanded to be tested on eight separate occasions, the first demand within thirteen minutes of refusing to sign the form. After considering the reasoning of the jurisdictions holding that a refusal cannot be recanted, the Hawaii court held:

We . . . decline to hold with a rule of law which would rigidly and unreasonably bind an arrested person to his first words spoken, no matter how quickly and under what circumstances those words are withdrawn. We consider the better rule to be one which takes into consideration the fairness to all parties of permitting an arrested person later to change his mind.

Moore, 614 P.2d at 935.

Alaska recently reached the same result on the issue of whether subsequent consent is a defense to the charge of refusal to submit to a chemical test under implied consent laws. In Alaska, refusal to submit to a chemical test is a criminal offense in and of itself. Lively v. State, 804 P.2d 66, 69 (Alaska App. 1991). That court lists two basic rationales behind the adoption of the rule that subsequent consent can cure a prior refusal. The first reason is fairness to the arrestee. The court quotes from Gaunt v. Motor Vehicle Div., Dep't of Transp., 136 Ariz. 424, 666 P.2d 524, 527 (Ariz. Ct. App. 1983):

Although an absolute rule preventing a subsequent consent after an initial refusal has the advantage of granting unmistakable clarity to the defendant's obligation under the implied consent law, it could lead to unnecessarily harsh and self-defeating results.

The Alaska court stated that the other basis for the subsequent consent rule is the belief that this rule best furthers the purpose of the implied consent statutes by encouraging the administration of chemical tests in as many cases as possible. Lively, 804 P.2d at 70. Using this second rationale as the basis for its holding, the Supreme Court of Kansas reasoned:

The chemical testing system provided under our implied consent law is important because it provides the best available and most reliable method of determining whether a driver is `under the influence' of alcohol. It protects both the accused and the public. A refusal to submit to the test, on the other hand, invokes serious consequences for the person arrested. We believe that the administration of the test should be encouraged and the person arrested should be given every reasonable opportunity to submit to it. For this reason, we hold that an initial refusal may be changed or rescinded, and if rescinded in accordance with the following rules, cures the prior refusal.

Standish v. Department of Revenue, Motor Veh. Div., 235 Kan. 900, 683 P.2d 1276, 1280 (1984). The Kansas court held that to be effective, the subsequent consent must be made:

(1) within a very short and reasonable time after the prior first refusal;

(2) when a test administered upon the subsequent consent would still be accurate;

(3) when testing equipment is still readily available;

(4) when honoring the request will result in no substantial inconvenience or expense to the police; and

(5) when the individual requesting the test has been in the custody of the arresting officer and under observation for the whole time since arrest.

Standish, 683 P.2d at 1280.

The more rigid view is illustrated by Schroeder v. Department of Motor Vehicles, 105 Nev. 179, 772 P.2d 1278 (1989). The Supreme Court of Nevada held that a subsequent request to take a chemical sobriety test does not vitiate a prior refusal. The arrested motorist in Schroeder refused a chemical sobriety test for at least forty minutes. After the arresting officer left and returned to his patrol the motorist changed his mind. The Nevada court affirmed the judgment of a district court, which refused a petition for judicial review of the decision of the department of motor vehicles which revoked the motorist's driving privileges. As a rationale for its holding, the Nevada court also cited the two basic rationales used in the jurisdictions that implement the "bright-line" rule. The court explained that expecting an arresting officer to consider a refusal as conditional so that he must remain near the arrested person for an extended period of time, is unreasonable. Such a rule would require the arresting officer to drop other duties to arrange for a belated test that the motorist had already refused after receiving warnings of the consequences of his refusal. Schroeder, 772 P.2d at 1280. The second rationale is that a driver must not be given the opportunity to unreasonably delay a test because one immediate purpose of the implied consent statutes is to obtain the best evidence of a motorist's blood alcohol content at the time an arresting officer reasonably believes him to be driving under the influence. Schroeder, 772 P.2d at 1280.

Comparing the rule in Standish to the facts in Schroeder, the two cases are clearly consistent. Because the arresting officer was no longer present, the same fact situation in Kansas would appear to lead to the same result as that reached by the Nevada court. The rationale for Schroeder would not apply to the case at bar because a decision to test the appellee after his recantation would neither have inconvenienced the arresting officer nor resulted in an unreasonable delay in administering the test. The comparison of Standish and Schroeder exemplifies the difficulty in artificially categorizing jurisdictions as two separate camps. The cases represent more of a continuum. The resolution of each case depends upon the facts with consideration of the implications on law enforcement and the legislative purpose in enacting the implied consent statutes.

Wisch v. Jensen, 221 Neb. 609, 379 N.W.2d 755 (1986) is cited by other jurisdictions as a rigid application of the "bright-line" rule. The case is cited by those jurisdictions for the fact that the motorist changed his mind and agreed to take a breath test within thirty seconds of his refusal but the arresting officer refused to allow the test. The facts of the case reveal that the motorist was profane, cocky and uncooperative. He had been told when he was arrested that he would be asked to take a breath test. When he arrived at the police station where the test was to be given, the officer twice read to the motorist an implied consent advisement postarrest form including the consequences of refusal. The motorist both times refused to sign the form. The officer dismissed the technician. But as she was leaving the motorist changed his mind. Even the jurisdiction recognized as being the most restrictive gave a belligerent motorist advanced warning, and two opportunities to agree to the test.

After analyzing the two lines of cases, the Court of Appeals of Idaho concluded:

The choice between these two schools of thought is not an easy one. The state, particularly at oral argument, has made a strong presentation in favor of the `bright line' rule. If our choice turned simply upon balancing the asserted benefits of simplicity and convenience under the `bright line' rule against the individualized fairness sought to be achieved by the flexible rule, we would find the outcome very problematic indeed. But when we consider the additional policy rationale for the flexible rule — that it better serves the public interest in obtaining scientific information about the blood alcohol levels of motorists accused of driving under the influence, we believe the issue must be resolved in favor of the flexible rule.

Matter of Smith, 115 Idaho 808, 770 P.2d 817, 821 (Ct.App. 1989). The Idaho court held that a motorist could reconsider after initially declining to take the test, if he gave a timely and unequivocal assent. The Idaho court declared that a delayed assent would be deemed timely only if it were given: (1) While the motorist was still in police custody; (2) When testing equipment and personnel were readily available; and (3) Before the delay produced by the initial declination would cause the outcome of the test to be materially affected. The court placed the burden upon the motorist to prove by a preponderance of the evidence that the requirements were satisfied.

We are not persuaded that law enforcement officers would be inconvenienced by allowing the arrestee to change his mind when he has arrived at the place where the test would be conducted. In the case at bar, the appellee was still in the custody of the arresting officer, the test equipment was readily available, and no substantial delay had taken place from the time of the refusal to the time the appellee recanted. Even the appellant admits, and the facts from our sister jurisdictions reveal, that arrested motorists are typically given more than one opportunity to agree to take the blood alcohol test. Arresting officers apparently recognize that the circumstances of the arrest along with the altered mental state of a drunk driver could result in an initially rash decision, which a few minutes of reflection by a ride to a jail in a patrol car could correct. We are persuaded that when the facts of the cases arising in sister states are examined, there is little authority for an inflexible rule.

As stated above, we hold that a motorist has not refused the test mandated by the Implied Consent Law if the assent is timely and given unequivocally. We adopt the five-element test for timeliness as provided by the Supreme Court of Kansas in Standish, quoted above. The burden of proof is on the motorist, who must assert the subsequent consent as an affirmative defense to an allegation of refusal to take the implied consent test.

Accordingly, the opinion of the Court of Appeals is VACATED. The judgment of the trial court is AFFIRMED.
