The Road Closed (MMS-ADV-31) multi-message sign is a 600 × 600 millimetre traffic yellow panel designed to notify motorists that a road ahead is closed to traffic. Commonly used for major roadworks, civil projects, emergency works, or hazardous conditions, this sign provides clear instruction for drivers to stop and seek alternative routes. Manufactured in compliance with Western Australia Government traffic control requirements, the panel integrates seamlessly with the state’s approved multi-message frame system.
As part of Western Australia’s modular multi-message system, the Road Closed panel can be displayed independently or paired with other signs such as “Detour Ahead” or “Local Traffic Only” to form a compliant, adaptable display. The approved frame supports multiple 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 modular system allows councils, contractors, and traffic management providers to update or replace panels quickly as conditions change.
Produced with CL400 Class 1W reflective material in traffic yellow, the Road Closed panel provides strong visibility during daylight, at night, and in poor weather. Its durable, weather-resistant construction complies fully with Australian traffic sign standards, delivering long-lasting performance under demanding conditions. By clearly communicating closures, the sign reduces confusion, improves compliance, and enhances safety for both motorists and work crews.
For planned works, emergency closures, or civil construction projects, the Road Closed (MMS-ADV-31) sign provides trusted compliance, high visibility, and dependable durability in one modular panel.
