This report outlines the application of a methodology developed for assessing the impact of a potential length increase for PBS Level 1 vehicles, based on the assessment criteria identified and discussed in workshops conducted in 2011. Fifty-five sample sites were chosen from across Australia, and a risk score showing the impact of a length limit increase was determined. A benefit-cost analysis of three sites was also conducted. The report recommends that an increase in the maximum vehicle length for PBS Level 1 vehicles to 23 m be considered. All sites would need to be assessed to determine the impact on network access, and ultimately road owners and managers will need to determine the acceptable level of risk in allowing longer vehicles on the network.
