Road Work Ahead TM1-1A (600x600mm) corflute Multi-Message Sign (MMS) panel warns motorists that roadworks are present ahead and that traffic conditions may change. It is used as an advance warning panel to prepare drivers for reduced speeds, lane closures, detours or other temporary traffic control measures.

The signface layout, legend and colours follow the applicable AS 1743:2023 design specifications for the TM1-1A code and the Victorian TM1-V1-1 variant. This warning MMS panel is built as a modular component for integration into compatible temporary traffic management frame systems, including the Multi-Message Sign Frame No. 1.

UAGS temporary traffic sign corflute panels are manufactured on 6mm UV stabilised corflute using Class 400T full-cube prismatic retroreflective yellow sheeting. The retroreflective yellow background and bold black legend support visibility in daytime and low-light traffic management environments. The lightweight construction is suited to transport, deployment and repositioning across changing work zones.

In a typical traffic control sequence, this panel is encountered before lane or directional instructions, providing early warning of approaching temporary traffic conditions. It is commonly followed by speed reduction, lane closure or detour panels, helping drivers adjust before entering the active work area. This sign is widely used in roadworks, civil construction, maintenance activities and utility works where advance notice is required.

Selection, placement and use remain subject to the applicable TMP, TGS, project requirements, site conditions and relevant authority requirements.

Available for pickup or shipping through UAGS.

Road Work Ahead MMS Panel FAQs

What is the difference between a T1-1 and a TM1-1A Road Work Ahead sign?

The standard T1-1 code designates a standalone, heavy-duty boxed-edge metal road sign. The TM1-1A (national code) and TM1-V1-1 (Victorian variant) designate a 600x600mm lightweight corflute panel explicitly designed to slide into a Multi-Message Sign (MMS) frame system alongside other temporary traffic signs.

Is this panel compatible with Victorian VicRoads and other state specifications?

Yes. This 600x600mm panel follows the applicable AS 1743:2023 signface design for the TM1-1A code and includes the Victorian TM1-V1-1 advance warning reference (VicRoads Drawing No. 541461). Other states and territories may use different local reference codes or drawing numbers for the same ROAD WORK AHEAD message, so final use should still match the applicable TMP, TGS, project requirements and relevant authority requirements.

What are the dimensions and thickness of this MMS panel?

This panel measures exactly 600mm x 600mm and is manufactured from 6mm thick industrial-grade, UV-stabilised corflute. The 6mm profile provides a practical balance of rigidity, weight and handling for portable Multi-Message Sign frame use.

What substrate material is used for this panel?

The panel is constructed from 6mm UV-stabilised industrial corflute (flute board). This lightweight and durable build makes it practical for portable sign frame integration, transport, and repeated site handling.

Does installing this sign ensure worksite compliance?

No. A single sign panel does not guarantee site compliance. Selection, placement, and use must be determined by an applicable Traffic Guidance Scheme (TGS) or Traffic Management Plan (TMP) prepared for your specific project and site conditions.
