Signals Not In Use (MMS-ADV-49) – Multi-Message Sign

The Signals Not In Use (MMS-ADV-49) multi-message sign is a 600 × 600 millimetre traffic yellow panel designed to inform motorists that traffic signals ahead are currently not operational. Commonly deployed during roadworks, maintenance, or when temporary lights are installed but inactive, this sign provides clear advance notice, preventing driver confusion and unsafe manoeuvres. Manufactured in compliance with Western Australia Government traffic control requirements, the panel integrates seamlessly with the state-approved multi-message frame system.

As part of Western Australia’s modular multi-message system, the Signals Not In Use panel can be displayed alone or paired with complementary warnings such as “Traffic Hazard” or “Prepare To Stop” to create one clear, compliant display. The approved frame supports both configurations—two 600 × 600 millimetre panels with a 1200 × 300 millimetre panel beneath, or one 1200 × 600 millimetre panel above with the same 1200 × 300 millimetre panel beneath. This modular flexibility enables councils, contractors, and traffic management providers to update displays quickly and efficiently as site conditions change.

Constructed with CL400 Class 1W reflective material in traffic yellow, the Signals Not In Use panel ensures maximum visibility in daylight, at night, and during adverse weather conditions. Its weather-resistant build complies fully with Australian traffic sign standards, delivering long-term reliability under harsh outdoor environments. By clearly advising that signals are inactive, the sign improves driver awareness and supports safer navigation through changing traffic conditions.

For temporary worksites, civil projects, and road closures requiring clear signal status communication, the Signals Not In Use (MMS-ADV-49) sign offers trusted compliance, strong visibility, and dependable performance in one modular panel.
