The freight industry is critical to the economy, and for many sectors it is heavy vehicles that underpin freight movements and prosperity. The average age of trucks in Australia and New Zealand is among the highest in the developed world. The oldest trucks are associated with higher environmental and health costs than newer trucks, yet these have been poorly quantified to date. Managing these issues is important to maintaining the freight industry’s social license. Austroads has published a research report which analyses the impacts of an ageing heavy vehicle fleet and explores measures that have been used to manage this challenge in Australasia and internationally.
