What it proves at audit

Heavy Vehicle Accreditation criteria this document produces evidence for. Check your readiness.

Why operators use it

We use FAT-06 to help a driver pause and make an honest, safe decision about whether they are fit to drive right now, physically, mentally and emotionally, and to make it easy to report a concern before it becomes harm.

From 1 August 2026, the Unfit to Drive Duty extends beyond fatigue. A driver of any heavy vehicle over 4.5 tonnes must not drive if they are not of sufficiently good health or fitness to drive safely. The NHVR expressly includes mental health conditions and psychological or emotional distress, alongside physical illness, injury and the effects of alcohol and other drugs. A driver may be licensed and medically fit generally but still be unfit at a particular time because of a temporary change in health or fitness.

From the companion guide that comes with this document.

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.
