Brief summary
This pilot study will evaluate the feasibility and acceptability of using a commercially available DRIVESC fitness-to-drive measurement tool to detect alcohol-induced impairment in healthy adult participants. The investigators hypothesize that DRIVESC can detect measurable changes in driving-related cognitive and motor performance across blood alcohol concentrations up to the U.S. per se legal limit of 0.08% g/210L ethanol. The study will enroll healthy adults aged 18-64 years (including both dosed and zero-alcohol arms) participating in the Wisconsin Breath Alcohol Examiner Specialist course, with each participant completing two study visits over two days.
Detailed description
A total of 18-22 participants will be enrolled in this single-site partial crossover pilot study. Under the auspices of the Wisconsin Basic Breath Examiner Specialist training, participants will be dosed with alcohol on the first, second, or neither day of the three-day training. This study design includes 6 double-alcohol-negative participants who will complete two days of alcohol-negative study tasks. The investigators will consider enrolling 12 alcohol-positive participants a success but are aiming to enroll 16 alcohol-positive participants. Alcohol-positive participants will complete two days of study tasks where one day is alcohol-negative and the other day is alcohol-positive. The order of positive-negative and negative-positive will be balanced. This range allows for flexibility in this feasibility study as study activities are scheduled in coordination with and around Chemical Testing Section training activities to minimize disruption to their educational tasks.

Fitness to Drive Screening test battery and computer cognitive tests to assess divided attention, reaction time, and working memory
OTHERAlcohol
participants are dosed as part of the Wisconsin Basic Breath Examiner Specialist Training offered by the Chemical Testing Section (and not by the study team) over a one-hour period to a breath alcohol up to the legal limit of 0.08 percent grams/210 liter ethanol

|---|---|---|
| Proportion of Enrolled Participants who Complete all Scheduled Activities | through day 2 | Data will be recorded as completed vs not completed measurements or timepoints for each participant session. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Within-Participant Change in DRIVESC Composite Score from Day 1 to Day 2: Non-Drinking Arm | through day 2 | The DRIVESC composite scoring is proprietary, but creates a single score representative of an individual's fitness to drive. It is calculated by combining the individual's performance on different cognitive and psychomotor assessments including measures of resilience, short-term memory recall, reaction ability, and completion of divided attention tasks. Scores range from 0-1 where 1 is the highest fitness to drive. |
