Modern AI dash cams not only watch the road but also monitor drivers. They track eye movement, posture, yawning, and other signs of drowsiness. If a driver seems sleepy, the system sends an audio alert, urging them to take a break.
Why This Matters
Long-haul truck drivers often work long hours and are at high risk of drowsy driving. Companies like Samsara, Motive, and Nauto use AI to detect early signs of fatigue. If the driver ignores the alerts, the system notifies fleet managers to step in and ensure safety.
How AI Detects Drowsiness
Each company’s system is trained to recognize different signs:
- Motive: Tracks yawning and head movement.
- Nauto: Monitors blinking, yawning, and body posture over time.
- Samsara: Detects more than 12 signs, including rubbing eyes and slouching.
These systems are based on the Karolinska Sleepiness Scale, which measures drowsiness on a scale of 1 to 9. Alerts are triggered when drivers reach dangerous levels of sleepiness.
Benefits for Fleet Operators
Fleet companies report fewer accidents since adopting AI dash cams. For example, an oilfield services company using Samsara dash cams reduced drowsy driving incidents from two per week to zero in the first month.
