Heavy refers to vehicles with a Gross Vehicle Mass (GVM) exceeding 3,500 kg - including buses (and minibuses), trucks, vans, and motorhomes. Agricultural machinery and other mobile equipment are excluded.
How many heavy vehicles are we seeing each month?
Trucks remain the backbone at ~60-65% share, though that's down from the 65-75% range seen in early 2024. Motorhomes have Oct-Nov spikes (38-44% share) in both 2024 and 2025 suggesting a seasonal registration pattern.
Buses and Heavy Vans hold steady in the 5-15% band.
Which heavy vehicle types dominate month to month?
The bus category encompasses both traditional large service coaches and smaller minibuses. Utility vehicles include a limited number of utes with a GVM above 3,500 kg (and are marked as commercial), and the “Other” fuel type represents a very small number of fuel cell vehicles.
