This is an appeal by defendant from a conviction of driving while undér the influence [DUI]. 28 V.S.A. § 1201(a)(2).
*354 Defendant was involved in a one-truck accident. The state police officer who arrived at the scene administered an alcosensor breath test, which measured defendant’s blood alcohol at .12 percent. As a result, he was then taken to the police barracks and given a gas chromatograph breath test, otherwise known as a crimper test, which showed a reading of .20 percent blood alcohol. Prior to trial, the State brought a motion in limine requesting that any evidence relating to the alcosensor test be excluded, and the trial court granted the motion over defendant’s objection. The only issue on appeal is whether it was error to grant the motion in limine and exclude all testimony relating to the results of the alco-sensor test.
The defendant claims: (1) that he had a right to use the test results in order to impeach the testimony of the state chemist regarding the results of the crimper test; (2) that since the statutory prohibition against using the alco-sensor test results, found in 23 Y.S.A. § 1202 (b), is designed solely for the protection of the defendant, he alone may be permitted to waive it; and (3) failure to allow evidence of alco-sensor test results prevented him from presenting a full and fair defense to the charge.
23 V.S.A. § 1202 (b) reads as follows:
A law enforcement officer may test an individual with a preliminary breath alcohol screening device one or more times in order to determine whether further and more accurate testing is appropriate. The results of the breath alcohol screening test shall not be introduced as evidence and a sample of this breath test need not be retained or delivered to the defendant. Notwithstanding the provisions of subsection (c) of this section, the individual shall not have the right to consult an attorney prior to submitting to this preliminary breath alcohol screening test.
Where the meaning of a statute is plain, there is no necessity for construction and the court is required to enforce the statute according to its express terms.
State
v.
Baldwin,
*355
Here the statute explicitly states that the preliminary test is a screening device only, to be used to aid an officer in determining whether further and more accurate testing is appropriate. The statutory language makes clear that neither the State nor defendant can introduce the results in evidence; instead, only the “more accurate” breath test results are admissible. Thus, having made a determination of the preliminary test’s reliability, see McCormick’s Evidence § 209, at 511 (2d ed. 1972), the legislature chose to limit its use to that of a screening device only, and provided that its results are inadmissible as substantive evidence of intoxication.
