Safety Barrier Products

Safety barriers are intended to safely redirect the majority of vehicles that have left the roadway.

The Austroads Safety Barrier Assessment Panel (the Panel) assesses the crashworthiness and suitability of road safety barriers, systems and devices for deployment on roads managed by Australian/New Zealand road agencies in line with AS/NZS 3845.


AS/NZS 3845.1:2015 and AS/NZS 3845.2:2017 outlines AASHTO Manual for Assessing Safety Hardware (MASH) as the current basis for crash testing protocol.  In line with AS/NZS 3845, the Panel has updated its product submission criteria and is transitioning the current suite of accepted products.

Roads and Maritime Services is adopting MASH as the nominal standard for road safety hardware in line with the Panel and AS/NZS 3845 with the following timeframes:

  • 31 December 2019:
    • Steel rail and permanent concrete safety barrier
    • Wire rope safety barriers
    • End Treatments (Terminals and Crash Cushions)
  • All contracts signed from 1 January 2022:
    • Temporary barriers systems (barriers and end treatments), part 2 products, transitions

MASH testing results will be used as the primary performance criteria in promoting any road safety hardware.  Therefore it is Roads and Maritime preference to select products that have undergone the full suite of MASH testing.

Product selection

Only products that have been assessed and accepted should be installed on the NSW classified road network.  This applies to all installations including permanent and workzone (temporary).

All accepted systems have acceptance conditions outlining the parameters under which the product is accepted for use.

Product acceptance conditions should be read in conjunction with Roads and Maritime Specification R132-Safety Barrier Systems and the Austroads Guide to Road Design Part 6: Roadside Design, Safety and Barriers.
