Length limits for b-doubles

The Draft Regulatory Impact Statement (RIS) compares a Regulatory Proposal that the length limit for B-doubles should be 26m (provided the trailing length is constrained to 20.6m) against the Alternative Proposal that the length limit remain at 25m (without any trailing length constraint). The Draft RIS compares the impacts of the two alternatives in the fields of safety, infrastructure and other (enforcement and the effect on existing equipment). It is concluded that the Regulatory Proposal has advantages over the present regulation, particularly in relation to the safety issues of safety equipment and vehicle dynamic performance, and has advantage for infrastructure, primarily reduced road wear. The constraint on trailing length ensures that the additional overall length would not be taken up by increased trailer length. As a result there is no productivity gains associated with the proposal.
