AS 4852.2:2019 PDF Download

AS 4852.2:2019 is a standard that specifically focuses on portable variable message signs (VMS) used for traffic management and/or driver information applications. It is part of a series that also includes Part 1, which covers fixed signs, and this particular standard covers signs that are mounted and deployed on a re-locatable trailer.

The standard outlines the requirements for the design, construction, performance, and installation of these electrically powered VMS, including their associated control systems. However, it explicitly states that it does not cover passenger information signs at bus stops or train stations, portable signs used for advertising to road users, or portable signs that can only display a single message or a blank face.
