Product Overview

Summary: This SOP sets out a clear, step-by-step method for the correct placement of road signage to protect workers, road users, and pedestrians in Australian conditions. It aligns with key WHS and road authority requirements, helping your organisation manage traffic risks, avoid confusion, and maintain a defensible safety record on every job.

Incorrectly placed road signs are a leading contributor to near‑misses, traffic incidents and public complaints around roadworks and temporary traffic disruptions. This Road Signage Correct Placement Safe Operating Procedure provides a practical, field-ready framework for planning, installing, inspecting and removing road signage in line with Australian road authority and WHS expectations. It supports your team to set out signage that is visible, understandable and consistent, whether you are managing a short-term lane closure, a long-term civil project, or an emergency utility repair.

The SOP goes beyond a simple checklist by defining responsibilities, minimum separation distances, sign hierarchies, sight‑line requirements and methods for adapting layouts to local conditions such as speed environment, gradients, curves, night works and adverse weather. It helps organisations reduce the risk of collisions with work areas, protect vulnerable workers on or near live traffic, and demonstrate due diligence under WHS legislation and relevant road rules. With this procedure in place, you can standardise traffic management practices across crews, reduce rework driven by audits or client feedback, and provide clear guidance for training new staff and contractors.
