If you have been stopped on suspicion of driving under the influence in Virginia, the officer may ask you to blow into a small handheld device before making an arrest. This device \u2014 known as the Virginia preliminary breath test (PBT)<\/strong> \u2014 is one of the most misunderstood tools in DUI investigations. Understanding how the preliminary breath test works and your rights under Virginia law can significantly affect your case outcome.<\/p>\n

What Is the Virginia Preliminary Breath Test?<\/strong><\/h2>\n

A preliminary breath test is a portable, roadside breath-screening device used by law enforcement to estimate a driver’s blood alcohol content (BAC) at the scene of a traffic stop. It is distinct from the evidentiary breath test administered later at a police station on a calibrated Intoxilyzer machine.<\/p>\n

The PBT is not designed to produce the precise, scientifically reliable result required for a criminal conviction. Rather, its sole purpose under Virginia law is to provide officers with probable cause to make an arrest.<\/p>\n

The Governing Statute: Virginia Code \u00a7 18.2-267<\/strong><\/h3>\n

The preliminary breath test in Virginia is governed by Virginia Code \u00a7 18.2-267, titled Preliminary breath test of person suspected of violations involving alcohol<\/em>.<\/p>\n

The statute provides that any person who is suspected of a DUI offense under \u00a7 18.2-266 (driving while intoxicated), \u00a7 18.2-266.1 (persons under age 21 driving after consuming alcohol), or a local ordinance substantially similar to those provisions, may be requested by a law enforcement officer to submit to a preliminary breath test.<\/p>\n

Key Provisions of the PBT (\u00a7 18.2-267)<\/strong><\/h3>\n

Reasonable Suspicion Requirement<\/strong><\/h4>\n

The officer must have reasonable grounds to suspect a violation. A request for a PBT is not lawful unless the officer has a reasonable, articulable basis to believe the driver has consumed alcohol.<\/p>\n

Approved Device Requirement<\/strong><\/h4>\n

The test must be conducted with an approved device. The PBT device used must be one approved by the Superintendent of State Police.<\/p>\n

Refusal Has No Criminal Penalty (for most drivers)<\/strong><\/h4>\n

Refusal carries no civil or criminal penalty for most drivers. Unlike the evidentiary breath test, refusal to submit to a preliminary breath test is not a separate offense and does not result in automatic license suspension for standard Virginia operators.<\/p>\n

Results Not Admissible in Court<\/strong><\/h4>\n

Under \u00a7 18.2-267(D), the results of the preliminary breath test are not admissible as evidence of guilt in any prosecution for DUI offenses. The statute limits its use strictly to establishing probable cause for arrest.<\/p>\n

Why the PBT Matters \u2014 But Cannot Convict You<\/strong><\/h3>\n

The exclusion of the PBT result from evidence at trial is a critical protection for the accused. Because the device is not subject to the same calibration, certification, and chain-of-custody requirements as evidentiary breath tests, it is not considered reliable enough for proving guilt in court.<\/p>\n

However, the Virginia preliminary breath test still plays an important role in DUI investigations. If a driver submits to the test and registers a reading of 0.08 or higher, it can provide probable cause for arrest and lead to further evidentiary testing.<\/p>\n

Once arrested, the driver becomes subject to Virginia\u2019s implied consent law under \u00a7 18.2-268.2, which carries serious consequences for refusal.<\/p>\n

The Implied Consent Law and the Virginia Preliminary Breath Test<\/strong><\/h3>\n

It is important to distinguish the preliminary breath test from the post-arrest evidentiary test governed by Virginia\u2019s implied consent statute.<\/p>\n

Under \u00a7 18.2-268.2, any person operating a motor vehicle in Virginia is deemed to have consented to a breath or blood test after a lawful DUI arrest. Refusing this test can result in:<\/p>\n
