Tracking doesn't change who needs a work diary. Drivers of fatigue-regulated heavy vehicles need one when they work 100km or more from base under Standard Hours, or at any distance under BFM, AFM, ACA-Fatigue or exemption hours. Fatigue-regulated vehicles are trucks and combinations over 12 tonnes GVM, and buses over 4.5 tonnes built to carry more than 12 adults including the driver. Work within 100km of base under Standard Hours is covered by local area records kept by the operator.
