I.
By driving а vehicle on a highway or public vehicular area a person consents to administration of a chemical analysis if he is charged with driving while impaired. N.C.G.S. § 20-16.2(a). A person required to submit to chemical analysis has the right to contact an attorney and select a witness to view the procedures, but the testing may not be delayed for these purposes more than thirty minutes. Id. A chemical anаlysis that reveals a blood alcohol level of 0.10 or more is sufficient under N.C.G.S. § 20-138.1(a)(2) to support a conviction of the criminal offense of driving while impaired. Because a person required tо undergo chemical analysis *456 must decide whether to take the test and risk conviction on the basis of the result or refuse and have his license revoked for twelve months pursuant to N.C.G.S. § 2046.2(a)(2), defendant аrgues that the chemical analysis is a critical stage of the prosecution requiring the police to advise him of his constitutional rights and entitling him to counsel. Based on his argument that a critical stage is involved, defendant contends that allowing him only thirty minutes to obtain counsel is unreasonable and violates his right to counsel guaranteed by the sixth and fourteenth amendments to the United States Constitution аnd article I § 23 of the North Carolina Constitution. We disagree.
The administration of a chemical analysis to determine if a driver is acting under the influence of an impairing substance is not a critical stage of the prosecution. The cases of
State v. Hill,
We note that defendant has suggested that he was entitled under the rule of
Miranda
to be informed of his constitutional rights before undergoing a breathalyzer test. Based on the rule of
Schmerber
we have already held that admission of a breathalyzer test is not dependent on whether
Miranda
warnings have been given because the results of the test are not evidence of a testimonial or communicative nature.
Sedars,
II.
We next consider defendant’s claim that he was denied the equal protection of the laws in violation of the fourteenth amendment to the United States Constitution and article I § 19 of the North Carolina Constitution. Defendant bases his argument on the fact that after 1 January 1985 an individual сharged with driving while impaired must be given two chemical breath analyses. N.C.G.S. § 20-139.1(b3). At present only one analysis is required, and defendant was only given one breathalyzer test. Defendant contends that this results in an arbitrаry and capricious classification between similarly situated individuals because the classification between persons charged prior to 1 January 1985 and those charged afterward has no basis in fact. We do not believe that N.C.G.S. § 20-139.1(b3) creates an impermissible classification and hold that the Safe Roads Act does not deny defendant the equal protection of the laws.
A statute is nоt subject to the equal protection clause of the fourteenth amendment of the United States Constitution or article I § 19 of the North Carolina Constitution unless it creates a classification between different groups of people. In this case no classification between different groups has been created. All individuals charged with driving while impaired before 1 January 1985 will be treated in еxactly the same way as will all in *458 dividuals charged after 1 January 1985. The statute merely treats the same group of people in different ways at different times. It is applied uniformly to all members of the public and does not discriminate against any group. If defendant’s argument were accepted the State would never be able to create new safeguards against error in criminal prosеcutions without invalidating prosecutions conducted under prior less protective laws. Article I § 19 and the equal protection clause do not require such an absurd result. This assignment of error is overruled.
III.
Defendant contends that N.C.G.S. § 20-138.1(a)(2) offends due process by creating a conclusive presumption that a person found to have an alcohol concentration of 0.10 or more at any relevant time after driving has committed the offense of impaired driving. More specifically, defendant argues that the legislature has impermissibly declared individuals with an alcohol concеntration of 0.10 or more to be presumptively guilty of crime and that N.C.G.S. § 20-138.1(a)(2) is unconstitutionally vague.
It is well established law that a legislature may not declare an individual guilty or presumptively guilty of crime.
McFarland v. American Sugar Refining Company,
Defendant also argues that N.C.G.S. § 20438.1(a)(2) is void for vagueness and thus deprives him of duе process of law because a potential violator has no means of measuring the level of alcohol in his system and therefore, does not have fair warning when he has crossed the threshold of 0.10 alcohol concentration. This issue has already been decided against defendant, and we need not consider it further.
State v. Rose,
IV.
N.C.G.S. § 20-139.1(b2) provides that the results of a breath analysis are inadmissiblе if the defendant objects to their introduction into evidence and demonstrates that the instrument used to conduct the analysis had not been maintained according to the regulations of the Commission for Health Services. The analysis will also be excluded if the defendant shows that it was not performed within the time limits prescribed by those regulations.
Id.
Because driving with a blood alcohol concеntration of 0.10 constitutes the offense defendant argues that requiring him to demonstrate that the breathalyzer was not properly maintained places on him the burden of proof as to an essеntial element of the offense.
Mullaney v. Wilbur,
The State may permissibly put the burden of establishing affirmative defenses on the defendant.
Patterson v. New York,
After a careful consideration of the law we find the challenged portions of the Safe Roads Act to be constitutional and affirm the order of the Superior Court reinstating the charges against defendant.
Affirmed.
