The Lane Closed (MMS-POST-4) multi-message sign is a 600 × 600 millimetre traffic yellow panel designed to notify motorists of closed lanes ahead. Commonly used during roadworks, maintenance, or emergency traffic management, this sign provides clear direction for drivers to merge safely, adjust speed, and follow changed traffic patterns.
Manufactured in compliance with Western Australia Government traffic control requirements, the panel integrates seamlessly with the approved modular multi-message frame system. It can be displayed independently or paired with related warnings such as “Merge Left” or “Prepare to Stop” to create a compliant, adaptable display. The approved frame supports flexible 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 system allows councils, contractors, and traffic managers to update signage quickly and cost-effectively as conditions change.
Constructed with CL400 Class 1W reflective material in traffic yellow, the Lane Closed panel provides excellent visibility during daylight, at night, and in adverse weather conditions. Its durable, weather-resistant design complies with Australian traffic sign standards, ensuring reliable long-term performance in outdoor environments.
By clearly marking closed lanes, the Lane Closed (MMS-POST-4) sign enhances driver awareness, reduces confusion, and supports safer navigation through restricted road zones.
