How Eye and Face Tracking Reveal the Early Signs of Drunk Driving
Alcohol impairment remains one of the most persistent risks on the road, contributing to thousands of traffic fatalities each year worldwide. Traditional tools like interlocks and breathalyzers can be effective in certain cases, but they leave a major gap: what happens during the drive.
This ebook explores how advances in in-cabin sensing are beginning to close that gap. Drawing on rare real-world and controlled driving data, it shows how behavioral cues captured by Driver Monitoring Systems (DMS) can reveal the subtle signs of impairment before they escalate into dangerous driving behavior.
🔹 Why existing prevention tools miss what happens once the vehicle is moving
🔹 How regulations like the HALT Act and Euro NCAP 2026 are setting new expectations
🔹 What controlled studies reveal about the link between eye behavior and alcohol impairment
🔹 How DMS can detect impairment using the same hardware already required for distraction and drowsiness monitoring
🔹 Potential ways impairment detection could integrate with in-vehicle safety systems
