DUI Professional | Litigation-Support Blood Alcohol Analysis
DUI Professional is a web-based alcohol analysis platform for professional BAC simulation, retrograde extrapolation review, and drinking-pattern analysis. It helps attorneys, public defenders, forensic toxicologists, expert witnesses, law enforcement trainers, and legal education users visualize alcohol absorption and elimination over time with documented assumptions.
What is DUI Professional?
DUI Professional is BAC simulation software for modeling alcohol consumption timelines, expected BAC ranges, retrograde extrapolation scenarios, and professional reports.
How can DUI attorneys use BAC simulation?
DUI attorneys can compare a measured BAC with the alleged driving time, test drinking-pattern assumptions, identify rising-BAC questions, and prepare focused expert-review issues.
Who uses DUI Professional?
Users include DUI and criminal-defense attorneys, public defenders, forensic toxicologists, expert witnesses, law enforcement trainers, forensic laboratories, and CLE instructors.
Public Drink Database
Search reference drink profiles before you build a BAC simulation.
DUI Professional includes a searchable drink database organized by type, subtype, ABV, and reference serving volume. Open individual drink profiles for BAC workflow context, downloadable reference PDFs, and simulator-ready values.
Dynamic Charting
Chart visualization is immediately reactive to changes in parameters.
Save Simulations
Save and later edit every detail of a simulation.
Drink Fractions
Set drink volumes to fractions of full volume.
Keypoint Values
Identify modeled BAC values at specific times in a simulation.

Dynamic Visualizations
DUI Professional (DUI Pro) simulation interface offers a dynamic and user-friendly experience for BAC analysis. The "Live Bac (midrange)" button provides real-time BAC updates, while "Create new simulation" and "Save simulation" options allow for flexible session management. Users can input details in the "Subject field" and "Case notes" sections to tailor simulations. The "Drinks" panel enables adding drinks to a cumulative list, with options to adjust volumes in 25% increments or remove them, recalculating BAC accordingly. The chart dynamically updates with an "Expected maximum Bac" display and adjusts to parameter changes, prompting saves with yellow highlights. Keypoint times on the timeline let users set and adjust modeled BAC at specific moments, with upper and lower boundary BACs visible. The consumption timeline slider and chart options, like hiding the upper range, help users review BAC trends over time.
DUI Pro Applications
The DUI Professional (DUI Pro) simulation system supports professional BAC analysis across several contexts. In law enforcement training, it can be used for training scenarios and alcohol-timeline education. For alcohol education and counseling, it helps explain drinking-pattern risk and the timing of alcohol absorption and elimination. In workplace safety, it supports education and policy discussions. Within civil litigation, it helps organize alcohol-related timeline assumptions for professional review. In aviation safety, it can be used to demonstrate bottle-to-throttle timing and BAC concepts for safety training.
