Key takeaways
- Standard hours apply by default; BFM and AFM require accreditation and documented controls.
- BFM allows different work and rest limits in exchange for training, scheduling controls and record-keeping.
- AFM is tailored to an operation and must be approved by the regulator.
- Microsleeps can occur with your eyes open — treat early symptoms as a stop signal.
The three fatigue regimes
| Regime | Who it applies to | What it requires |
|---|---|---|
| Standard hours | Default for fatigue-regulated heavy vehicles | Set work and rest limits with no accreditation required |
| Basic Fatigue Management (BFM) | Accredited operators | Fatigue training, scheduling controls, record-keeping and audits |
| Advanced Fatigue Management (AFM) | Accredited operators with tailored arrangements | Regulator-approved risk management and monitoring |
Exact hour limits depend on the regime, the vehicle and any applicable exemption notice, so check the current NHVR guidance rather than working from memory.
Reading the symptoms
Heavy eyelids, missing exits, drifting within the lane, clusters of yawning and losing track of the last few minutes are all warnings. A driver experiencing microsleeps is critically fatigued regardless of what the work diary shows.
Practical strategies
- Plan rest stops before the shift, not once you are already tired
- Use a short nap rather than relying on caffeine alone
- Avoid heavy meals before night driving
- Keep the cab cool and well ventilated
- If you are adjusting the radio to stay awake, stop now
Records that protect you
Complete the work diary accurately and in real time. Record delays at depots and sites — they are useful evidence in a Chain of Responsibility investigation. If you decline to drive because of fatigue, note the time and the conversation.
