Australia's NHVR extends allowable fatigue hours for Great Western Highway detours Change Australia's NHVR issued a temporary exemption effective March 30–June 30, 2026, allowing fatigue-regulated heavy vehicle drivers using the listed Great Western Highway detour routes under Standard Hours to add up to 2 hours per 24 hours (to 14 hours) and up to 4 hours per 7 days (to 76 hours) while granting smaller additional limits for Basic and Advanced accredited drivers. Why it matters Drivers using the specified detours must meet new administrative and fatigue-control conditions before and during trips. Eligible drivers must record the exemption and the detour used in their work diary, and operations remain subject to limits on continuous work and night shifts to manage fatigue. bigrigs.com.au · Mar 31 More actions Like (sign in) Save (sign in) Share Facebook LinkedIn X / Twitter Copy link
