Why operators use it

We use FAT-04 to test whether fatigue and fitness-to-drive controls work in real operations, not merely whether the business has records stored in a folder.

Fatigue and fitness controls can fail even when a roster, work record or declaration exists. A schedule may be unrealistic, a record may be incomplete, a driver may not feel safe to report, a delay may be absorbed by unsafe pressure, an alert may be ignored, a site/customer/prime constraint may recur, or an action may be marked complete without fixing the underlying control. FAT-04 provides a structured, proportionate way to look for those failures and act early.

This is practical guidance based on current industry standards. You must verify specific requirements against the latest NHVR regulations or state-specific laws (e.g., WA/NT) before implementation.
