Driver fatigue doesn't suddenly appear at the moment of an incident. Driving behaviour changes first.
Readiness intelligence built from vehicle motion, control inputs and physical movement — never a camera, never facial analysis, never an image of anyone. That's a deliberate choice: it works in blue-light, public-sector and unionised fleets where a camera in the cab is a non-starter.
Steering micro-corrections, braking smoothness, lane discipline, seat and posture movement — captured continuously from the vehicle itself.
A readiness state is formed from those signals, weighted for the individual and their role, and placed into a clear zone rather than a raw number.
Green and amber go to the driver alone. A manager is involved only for genuine emergencies and unacknowledged red-zone alerts.
Their own readiness state, in the cab, privately. An early nudge to take a break — before it becomes a decision made at seventy miles an hour.
"At work." Nothing more, unless there is a genuine emergency or a red-zone alert nobody has acknowledged.
A safety system that gets people disciplined for being honest stops being told the truth — and then it isn't protecting anyone.
Motion, control inputs and body movement. No gaze tracking, no facial analysis.
A clear state rather than a raw number nobody can act on.
How readiness changes over hours on the road, and whether breaks restore it.
For automated systems: can this person take control inside the time available.
Separates consistently careful operators from consistently risky ones.
How many operators a given fleet size genuinely needs.
Whether a human action counted as oversight, guidance or control.
Every evaluation hash-chained, so the record can be shown to be unaltered.
