The Merge Left (MMS-POS-13L) multi-message sign is a 600 × 600 millimetre traffic yellow panel designed to direct motorists to merge safely into the left lane. Commonly deployed during roadworks, lane closures, or temporary traffic management, this sign provides clear advance notice to reduce speed, check mirrors, and merge in a controlled and safe manner.
Manufactured in compliance with Western Australia Government traffic control requirements, the panel integrates seamlessly with the state’s approved modular multi-message frame system. It can be displayed independently or paired with complementary signs such as “Lane Closed” or “Prepare to Stop” to form a compliant, adaptable display. The approved frame supports multiple layouts—two 600 × 600 millimetre panels above a 1200 × 300 millimetre panel, or one 1200 × 600 millimetre panel above with the same 1200 × 300 millimetre panel beneath. This modular setup enables councils, contractors, and traffic managers to update signage quickly and cost-effectively as site conditions change.
Constructed with CL400 Class 1W reflective material in traffic yellow, the Merge Left panel ensures excellent visibility in daylight, at night, and in adverse weather conditions. Its durable, weather-resistant build complies with Australian traffic sign standards, delivering long-term performance and reliability in challenging outdoor environments.
By instructing drivers to merge safely, the Merge Left (MMS-POS-13L) sign improves traffic efficiency, reduces congestion, and supports safer navigation in controlled traffic areas.
