The development of the ADRs continues as part of a program which includes amendments to existing ADRs, introduction of new ADRs, as well as a full review of existing ADRs where possible every ten years.
A number of changes to ADRs have been considered, including those detailed in the Safe Vehicles section of the National Road Safety Strategy 2011–20 and corresponding National Road Safety Action Plans. Further changes that build on this body of work are currently being considered in the National Road Safety Strategy 2021-30 by the Office of Road Safety.
Actions under the Strategy that have already been completed include antilock brake systems for motorcycles, protection of occupants in side impacts with narrow objects such as poles and trees, antilock or load proportioning brake systems for heavy vehicles, electronic stability control for light commercial vehicles, stability control systems for heavy vehicles and roll stability systems for heavy trailers.
Public comment on draft ADR amendments, draft new ADRs and draft reviews of existing ADRs is an important part of the process.
