The three parts of every DUI case
In the video, Virginia breaks a DUI case into three parts:- Driving – what happened on the road.
- Symptomology – what the officer says about how you looked, spoke, and moved.
- Toxicology – what the breath or blood test results show.
“You have to look at every case as there's a driving aspect to it. There's also the symptomology part, and then there's the toxicology part.”We use this three-part view in our day-to-day work. It helps us stay organized, look at your case from several angles, and talk with you in a way that makes sense.
How the prosecution’s story must fit together
One of the most helpful moments in the video comes when Virginia explains how these three parts must align for the State to move forward. She notes:“The driving, the symptoms and the toxicology all have to come together in the middle to show that there's no other reasonable explanation except that the person was impaired.”That simple sentence captures a complex legal idea. The State does not just point to one fact. It must pull together your driving pattern, your appearance, and the test results so that they all tell the same story. We keep that standard in mind when we review a file. We ask whether the evidence truly fits together or whether gaps or conflicts appear when you look closer.
Where real challenges often arise
The video also touches on how different cases call for different types of legal work. Virginia explains:“And if there isn't another reasonable explanation, then maybe we can run a motion about the driving. Or maybe we can do a challenge in regards to the symptoms. Or maybe we're going to have to take the case for toxicology reasons to trial. Or maybe we can run a motion on a blood test.”This part of the video shows that DUI defense does not follow a single script. Depending on the facts, your situation may raise issues about why the officer stopped you, how the officer described your behavior, or how the lab handled your sample. At Law Offices of Virginia L. Landry, Inc., we pay close attention to these details. Our focus on DUI law for more than three decades, along with Virginia’s Board Certification in DUI Defense Law, guides how we review each of these areas.
A method built on careful dissection
Near the end of the clip, Virginia sums up the heart of our approach:“What we have to do is dissect those three parts and figure out how many challenges you have from a legal or factual perspective for each one of those three.”This line reflects our values today:
- We look closely at the law and the facts in front of us.
- We break complex situations into clear parts so you can follow along.
- We stay committed to a structured, thoughtful way of working, not quick guesses.
How this video connects to our work today
Although the video focuses on one core concept, it captures how we still approach DUI cases in Orange County and across Southern California:- We draw on more than 34 years of work devoted to DUI defense.
- We rely on Virginia’s Board Certification in DUI Defense Law to help shape our analysis of driving, symptomology, and toxicology.
- We stay engaged in ongoing training and education so we can address current testing methods and procedures.
What to listen for when you watch
As you watch the video, you may want to listen for a few key ideas:- How breaking a case into driving, symptoms, and toxicology makes a confusing situation feel more manageable.
- How Virginia describes the need for all three parts to line up before the State’s story makes sense.
- How a careful review can uncover legal or factual issues that might not seem obvious at first glance.
