Case Summary
Blow v. Commonwealth, decided by Virginia Supreme Court on April 16, 2026, resulted in a defendant win outcome. The Supreme Court of Virginia reviewed a defendant's conviction for driving under the influence (DUI) and related charges. The core dispute centered on whether the arresting officer had reasonable suspicion to initiate a traffic stop based on the defendant's vehicle crossing the fog line.

The court held: The court held that an officer's observation of a vehicle crossing the fog line, even if momentarily, provides reasonable suspicion to believe a traffic violation has occurred, justifying a traffic stop.. The court reasoned that crossing the fog line is a violation of Virginia Code § 46.2-804, which requires drivers to stay within their lane.. The court found that the officer's testimony regarding the vehicle's movement was credible and sufficient to establish reasonable suspicion.. The court rejected the defendant's argument that the stop was pretextual, finding no evidence to support such a claim.. The court affirmed the trial court's denial of the defendant's motion to suppress the evidence obtained as a result of the traffic stop.. This decision clarifies that even a brief deviation across the fog line can be sufficient grounds for an officer to establish reasonable suspicion for a traffic stop in Virginia.

Court Syllabus
Case Analysis — Multiple Perspectives
Plain English (For Everyone)
Imagine a police officer sees your car drift a little bit over the white line on the side of the road. Even if you didn't think you were doing anything wrong, the officer can stop you because they suspect you might be breaking a traffic law, like driving while impaired. This court said that seeing a car cross the fog line is enough reason for an officer to pull you over and investigate.
For Legal Practitioners
The Supreme Court of Virginia affirmed a DUI conviction, holding that an officer's observation of a vehicle crossing the fog line, even momentarily, establishes reasonable suspicion for a traffic stop. This ruling reinforces the established precedent that minor traffic infractions, such as crossing the fog line, are sufficient to justify an investigatory stop. Practitioners should advise clients that even de minimis deviations from lane markings can lead to lawful stops, impacting suppression arguments in DUI and other traffic-related cases.
