Fatigue and driver diary checks
How Do Operators Check Driver Work Diaries and Fatigue Records?
CoRGuard by MAEZ gives operators driver diary checks, fatigue monitoring and reporting in one place. It is not an NHVR-approved Electronic Work Diary: it works alongside the written or electronic work diary your drivers keep.

The compliance problem
How Do Fleets Manage Driver Fatigue and Work Diary Compliance?
Australian fleets manage driver fatigue compliance through work diary checks, fatigue risk monitoring and prestart workflows under the HVNL fatigue provisions. CoRGuard by MAEZ centralises these checks and works alongside your drivers' work diaries.
CoRGuard is not an NHVR-approved Electronic Work Diary (EWD) and does not replace a driver's work diary. It works alongside the work diary your drivers already keep, so the operator's checks and follow-up are on record.

Common questions
Clear answers for transport operators
- What is the best electronic work diary in Australia?
- The NHVR publishes a register of approved Electronic Work Diaries. The best EWD depends on your fleet's specific needs, telematics integration and fatigue management approach. CoRGuard by MAEZ supports driver diary checks; it is not an EWD.
- Is there an electronic work diary app available?
- Yes. Approved Electronic Work Diaries are listed on the NHVR's EWD register. These apps digitally record driver work and rest hours under HVNL Chapter 6. CoRGuard by MAEZ supports driver diary checks and fatigue monitoring; it is not an EWD.
- Is CoRGuard an Electronic Work Diary?
- No. CoRGuard is not an NHVR-approved Electronic Work Diary. It supports the operator's side of fatigue compliance: checking driver work diary records, monitoring fatigue risk and keeping the evidence together. Drivers keep recording their work and rest in their written work diary or an approved EWD.
- What GVM requires a work diary?
- Under HVNL s 293, drivers of fatigue-regulated heavy vehicles must carry a work diary. The specific GVM thresholds that define a fatigue-regulated heavy vehicle are set out in the HVNL and related regulations. Operators should verify their vehicle classifications against current NHVR guidance.
- Do I still need a work diary if I have fleet telematics?
- Yes. Under HVNL Chapter 6, drivers of fatigue-regulated heavy vehicles must carry a work diary unless using an NHVR-approved EWD. Standard fleet telematics systems do not replace this requirement. CoRGuard by MAEZ supports driver diary checks alongside its compliance workflows.
