1 APRIL 2015 DETAIL SHEET SMART STEEL CRASH CUSHION VicRoads Requirements Refer to Austroads - Safety Barrier System Acceptance Conditions for the SMART Steel Crash Cushion. All requirements listed by Austroads have been adopted by VicRoads for use on the Victorian declared road network. In this instance, VicRoads applies additional requirements/conditions for use of SMART Steel Crash Cushion on the Victorian declared road network including: The crash cushion is to be fitted with a plastic motorcycle friendly cover that fits over the impact head and must include a white and black retro-reflective hazard marker. Please Note: VicRoads requirements take precedence over any Product Manual instructions and Austroads conditions where conflicting. References Product Installation Manual and Product Operational Manual refer licensed product supplier website VicRoads Road Design Note Accepted Safety Barrier Products For further information please contact: VicRoads Technical Services 60 Denmark Street Kew, Vic, 3101 Telephone: Accepted safety barrier products are subject to periodic review and the information provided in this document may be superseded. Please refer to Road Design Note Accepted Safety Barrier products for the current VicRoads acceptance status.

Traceability must be in a form that will not be erased with use. Notes Acceptance is based on drawings in the Product Manual supplied by the Proponent, dated July This acceptance will cease if there is any change in the product design or specifications. Only the Product Manual prepared by the Proponent shall be used in any marketing of the product. Acceptance of the SMART Steel Crash Cushion does not place any obligation on the road authority, or its contractors, to purchase or use the product. The Austroads Safety Barrier Assessment Panel may periodically reassess the SMART Steel Crash Cushion. The road authority may withdraw or modify at any time, the acceptance status or conditions of use of the product without notice. Users should refer to the road authority web site to ensure they have the latest version of the conditions related to this product. Page 3 of 4
