Reviewed against Virginia sources current as of August 21, 2026. The word “breathalyzer” is often used for two legally different processes: a roadside preliminary breath analysis and a post-arrest chemical breath test. Their purposes, refusal rules, and use in court are not the same. This page provides general information and does not determine whether a test, charge, suspension, or refusal allegation is valid in a particular case.
| Testing stage | Current Virginia framework |
|---|---|
| Roadside preliminary breath analysis | Virginia Code § 18.2-267 governs this preliminary test during a roadside investigation. A person has a statutory right to refuse it, and that refusal is not evidence in a prosecution for an offense listed in the section. The preliminary result is not admitted at the DUI trial. |
| Post-arrest chemical breath test | Virginia Code § 18.2-268.2 governs implied consent when its highway-operation, arrest, timing, and offense conditions are met. An unreasonable refusal of a required test is addressed separately by § 18.2-268.3. |
A page that treats both stages as one test can give the wrong answer about refusal, admissibility, or license consequences. The warrant or summons, arrest time, alleged location of operation, advisement, test records, refusal paperwork, and prior record can all affect the analysis.
Section 18.2-267 gives a person suspected of a listed DUI-related offense the right, if equipment is available, to have a preliminary breath analysis. The person may observe the process and see the reading. The Department of Forensic Science determines the proper method and equipment for this preliminary testing.
The same section gives a stopped and suspected person the right to refuse the preliminary analysis. It states that the refusal is not evidence in a prosecution for one of the listed offenses. An officer must advise the person of the rights in the section.
A preliminary reading indicating alcohol may be part of the charging-stage process, but § 18.2-267 states that the result is not admitted into evidence at the DUI trial. The section separately addresses use at a probable-cause suppression hearing if the officer did not give the required advisement. Those rules are different from the post-arrest test provisions.
Under § 18.2-268.2, a person who operates a motor vehicle on a Virginia highway is deemed to have consented to specified chemical testing if arrested for a listed offense within three hours of the alleged offense. For the alcohol-related provisions identified in subsection B, the statute calls for a breath test. If that test is unavailable or the person is physically unable to submit, a blood test is given. Drug and combined-influence allegations are addressed under separate language in the section.
Before a post-arrest breath test is administered, the accused must be advised of the right to observe the analysis and see the reading. If the equipment automatically produces a written printout, the printout or a copy must be given to the accused. Whether the implied-consent statute applies is a legal question that depends on the statutory conditions and the case record.
Virginia Code § 18.2-268.9 states that a chemical breath analysis must be performed by a person with a valid license, using a type of equipment and methods approved by the Department of Forensic Science, to be capable of being considered valid as evidence. The test certificate records specified information, including the test date and time, result, examiner, approved-procedure statement, and advisement about observing the process and seeing the reading.
The Virginia Department of Forensic Science Breath Alcohol Section trains and licenses operators, maintains and certifies evidential equipment used in Virginia, and provides records. The Department states that it certifies each evidential instrument for accuracy at least every six months. Virginia’s breath-alcohol testing regulations separately address approved devices, methods, licensing, records, checklists, and preliminary devices.
Section 18.2-268.9 makes certificate admissibility in a criminal case subject to the notice and objection framework in Virginia Code § 19.2-187.1. That statute contains time-sensitive procedures. Anyone with a pending matter should rely on the actual court filings and current legal advice, not a webpage, to calculate or protect a deadline.
Virginia Code § 18.2-268.11 also matters. It describes the testing steps in §§ 18.2-268.2 through 18.2-268.9 as procedural and states that substantial compliance is sufficient. Noncompliance does not by itself require a finding of not guilty; the statute allows evidence of noncompliance and resulting prejudice to be considered with the other evidence. A discrepancy therefore should not be described as an automatic exclusion, dismissal, or acquittal.
Virginia Code § 18.2-266 includes several alternative DUI theories. Clause (i) addresses a qualifying chemical-test result of at least 0.08 percent by weight by volume of alcohol in blood or at least 0.08 grams per 210 liters of breath. Other clauses separately address being under the influence of alcohol, drugs, or a combination of alcohol and drugs, as well as specified concentrations of certain drugs.
The 0.08 provision in § 18.2-266(i) is an independent statutory basis, not merely a generic “legal limit.” In specified impairment prosecutions, Virginia Code § 18.2-269 separately supplies rebuttable presumptions for qualifying chemical analyses: 0.05 or less, more than 0.05 but less than 0.08, and 0.08 or more are treated differently under that section.
A result below 0.08 does not categorically prevent an alcohol-impairment allegation under § 18.2-266(ii). A result at or above 0.08 does not remove the need to prove the applicable offense and address admissibility and other case-specific issues. Under § 18.2-268.10, admission of a blood or breath result does not prevent either side from introducing other relevant evidence, and the court considers other admissible evidence of the accused’s condition.
The roadside right to refuse under § 18.2-267 should not be confused with an alleged unreasonable refusal of a test required under the post-arrest provisions. Section 18.2-268.3 treats a first unreasonable refusal of a required breath test as a civil offense with a one-year suspension. A qualifying later breath-test refusal within 10 years is a Class 1 misdemeanor and carries a three-year loss of the privilege to drive. The section treats blood-test refusal as civil, with the suspension period depending on qualifying history.
The refusal statute also specifies advisement and sworn-form procedures. Current subsection F permits a person found guilty of a first refusal and suspended under the identified first-offense provisions to petition for a restricted license. Any grant depends on good cause and statutory conditions, including ignition-interlock and alcohol-safety-program requirements; commercial-motor-vehicle operation is not authorized by that restricted license.
Under § 18.2-268.10, a finding of unreasonable refusal may be admitted in the DUI trial only to explain why no chemical test is present and may not be treated as evidence of guilt. This page does not advise anyone to take or refuse a test. The requested test, advisement, timing, medical circumstances, prior history, and paperwork require individual review.
Virginia Code § 46.2-391.2 provides an immediate administrative-suspension process when its post-arrest test or refusal, charging, and notice conditions are met. The stated period is seven days for a first-offense charge, 60 days for a second-offense charge, and generally until trial for a third-or-subsequent charge. The statute also provides a process for court review.
A roadside preliminary reading alone is not the trigger described in § 46.2-391.2. The administrative process is also distinct from any suspension or revocation that may follow a later conviction or refusal finding. The current page should not promise or predict a suspension, reinstatement, restricted license, vehicle disposition, or court result without reviewing the actual records.
Not every item exists or is available in every matter, and no single item establishes a defense or result. Relevance, admissibility, statutory compliance, prejudice, and the available procedural response depend on the facts and posture of the case.
The official Virginia Beach General District Court page publishes current location, contact, and scheduling information for DUI-related matters. Schedules can change. Start with the court and date shown on the charging papers, then verify current case information with the court. This page does not determine venue, appearance requirements, or the correct court for a particular charge.
Is a roadside preliminary result admitted at the DUI trial? Section 18.2-267 says no. The same section contains a separate rule concerning probable-cause use at a suppression hearing and the officer’s required advisement.
Is the roadside refusal rule the same as the post-arrest rule? No. Section 18.2-267 provides a right to refuse the preliminary analysis. Sections 18.2-268.2 and 18.2-268.3 govern the different post-arrest testing and unreasonable-refusal framework.
Does a reading below 0.08 end the inquiry? No. Virginia has separate test-result and impairment provisions. The charged clause and all admissible evidence must be considered.
Does a procedural difference always exclude a formal result? No. Section 18.2-268.11 makes substantial compliance sufficient and requires noncompliance and resulting prejudice to be considered with the evidence. The applicable record and legal issue still require review.
Can a lawyer guarantee suppression, dismissal, or a particular license result? No. A prior result, testimonial, ranking, or credential does not determine a pending case. No outcome should be promised.
