TM1-V108 / GM9-90B DO NOT OVERTAKE (1200x300mm) corflute sign panel instructs motorists to remain in their lane and prohibits overtaking through active work zones where lane conditions, visibility or traffic control measures make passing unsafe. It is used to maintain controlled traffic flow and prevent conflicts between vehicles in constrained environments.

Manufactured from 6mm corflute board and faced with retroreflective white Class 1W full-cube prismatic sheeting, this panel delivers strong visibility in both daytime and night-time conditions. The lightweight construction allows for quick installation, relocation and pack-down while maintaining durability across repeated use in temporary traffic control setups.

Compliant with AS 1742 and AS 1743, and meeting reflective performance requirements including AS/NZS 1906.1 Class 1W, RTA NSW Class 1X and DTMR QLD Class 1X, this sign is designed for integration into standard traffic management layouts. It is typically installed in the lower panel position of the Multi-Message Sign Frame No. 1, where it reinforces regulatory instruction beneath advance warning signs.

In a typical traffic sequence, motorists first encounter advance warning such as ROAD WORK AHEAD signage, followed by speed reductions and lane control measures, before this panel enforces the restriction on overtaking through the work area. This is commonly applied in resurfacing works, single lane operations, temporary alignments and narrow corridor projects where maintaining lane discipline is critical.

This type of sign is commonly specified in temporary traffic management plans prepared under AS 1742 to guide motorists safely through changing traffic conditions. Available for pickup or shipping through UAGS.
