Queensland, New South Wales, Victoria, South Australia, Tasmania and the Australian Capital Territory have adopted the Heavy Vehicle National Law (HVNL) and Regulations for heavy vehicles over 4.5 tonnes gross vehicle mass. For further detail please refer to the below;
Oversize/over mass (OSOM) vehicles that are in excess of 2.5 in width, 19 metres in length, 4.3 metres in height or in excess of 42.5 tonnes are denied general access to the Australian road network unless they have road-friendly suspensions, travel on approved routes and as the load size and the journey length increase, the number of affected road managers and the time required to assess OSOM vehicle applications will increase.
Road transport operators cannot legally move an OSOM vehicle from a port without approval from relevant road managers. Goods and loads may attract storage charges and other penalties, while waiting for the permit. Clients and service providers should advise prospective road transport operators of the item details as soon as possible and well before the item arrives in Australia.
