What is BAC simulation software?
BAC simulation software estimates how blood alcohol concentration may rise and fall over time based on drinks, body weight, biological sex, timing, absorption assumptions, and elimination assumptions.
Who uses DUI Professional?
DUI attorneys, expert witnesses, forensic laboratories, law enforcement trainers, and CLE instructors use BAC simulation to make alcohol timelines easier to evaluate and explain.
Move beyond a single BAC estimate
A single calculation rarely captures the uncertainty in an alcohol case. A simulation can show ranges, keypoint times, peak estimates, and the impact of changing assumptions.
What DUI Professional models
The platform supports drinking-pattern analysis, partial drinks, drink type selection, custom drink data, keypoint BAC values, and report generation for professional review.
- Expected average BAC curve
- Minimum and maximum BAC ranges
- Peak BAC timing
- Keypoint BAC values
- Consumption-phase visualization
- PDF and HTML report output
Frequently Asked Questions
What inputs does a BAC simulation need?
Common inputs include drink type, quantity, alcohol concentration, drinking start and stop times, body weight, biological sex, and elimination assumptions.
Why use a BAC range?
A range helps reflect physiological variability and assumption uncertainty instead of implying false precision from a single number.
Is BAC simulation the same as a breath test?
No. Simulation estimates a timeline from assumptions and inputs; breath or blood tests are measurements that may be compared against the model.

DUI Professional does not determine guilt, impairment, admissibility, or the legal sufficiency of evidence. It provides structured BAC scenario modeling and report support for qualified professional review. Legal conclusions and forensic opinions should be made by appropriately qualified professionals using case-specific facts, jurisdiction-specific law, and applicable scientific standards.
