Our definition of tiredness

The driver yawned and/or closed their eyes for at least 3 seconds, twice within 2 minutes.


How tiredness is detected

A Tiredness tag is applied by:

  • Camera AI: The driving behavior is detected by the AI Dashcam in real-time, alerts the driver (if in-cab alerts are enabled) and triggers a video event in Reveal.

How to prevent videos falsely triggering

Videos can be falsely triggered, usually when an AI Dashcam lens is obstructed or in the wrong position.

Learn how to prevent irrelevant video events.


How tiredness affects a driver's safety score

When tiredness is detected, it negatively impacts the Video driver safety score. Riskier behaviors impact the score more negatively than others.
