Validation of Alcohol Level Identification Using DRIVESC

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.
