The Merge Left (MMS-POS-9L) multi-message sign is a 600 × 600 millimetre traffic yellow panel designed to alert motorists of lane reductions or roadworks requiring traffic to merge to the left. Frequently used in temporary traffic management, civil construction, and maintenance projects, this sign provides clear advance warning to help drivers adjust safely and maintain orderly traffic flow. Manufactured in compliance with Western Australia Government traffic control requirements, the panel is fully compatible with the state’s approved multi-message frame system.
As part of Western Australia’s modular multi-message system, the Merge Left panel can be displayed independently or paired with complementary warnings such as “Reduce Speed” or “Prepare To Stop” to form one clear, compliant display. The approved frame supports both layouts—two 600 × 600 millimetre panels above a 1200 × 300 millimetre panel, or a single 1200 × 600 millimetre panel above with the same 1200 × 300 millimetre panel beneath. This flexibility allows councils, contractors, and traffic management providers to adjust signage quickly as conditions change.
Constructed with CL400 Class 1W reflective material in traffic yellow, the Merge Left panel ensures high visibility in daylight, at night, and in poor weather conditions. Its durable, weather-resistant build complies fully with Australian traffic sign standards, offering long-term performance in demanding environments. By clearly directing traffic to merge left, the sign enhances driver awareness, reduces risks, and improves safety for both road users and workers.
For lane closures, diversions, and roadworks, the Merge Left (MMS-POS-9L) sign provides trusted compliance, standout visibility, and reliable durability in one modular panel.
