In the second article in our three-part series on alcohol impairment, we unveil the discovery of a new biomarker: the Optalert Intoxication Scale. Optalert’s algorithm detects alcohol-related driver impairment in real-time, unlocking a new chapter in road safety. Our first article detailed how impairment persists for hours after blood alcohol concentration (BAC) declines.  The study...

In the first of our three-part series about driver intoxication, we reveal how impairment persists for hours after blood alcohol concentration falls. BAC peaked 1.5 hours after drinking alcohol, while impairment peaked at the five-hour mark. Understanding the relationship between blood alcohol concentration (BAC) and impairment is critical to improving road safety and moving us...
