Prepare To Stop (MMS-ADV-27) – Multi-Message Sign

The Prepare To Stop (MMS-ADV-27) multi-message sign is a 600 × 600 millimetre red panel designed to warn motorists that they must be ready to come to a complete stop ahead. Commonly used in roadwork zones and temporary traffic management sites, this sign provides drivers with early notice of stop/slow conditions, temporary signals, or traffic controllers operating on the roadway. Manufactured in compliance with Western Australia Government traffic control requirements, the panel is fully compatible with the state-approved multi-message frame system.

As part of Western Australia’s modular multi-message system, the Prepare To Stop panel can be displayed independently or paired with complementary warnings such as “Traffic Controller” or “Reduce Speed” to create a compliant, modular display. The approved frame supports multiple configurations—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 format allows councils, contractors, and traffic managers to update signage quickly and cost-effectively as site conditions change.

Produced with CL400 Class 1W reflective material in red, the Prepare To Stop panel ensures outstanding visibility in daylight, at night, and in adverse weather. Its reflective surface provides drivers with ample warning to reduce speed and prepare to stop safely, protecting both road crews and motorists. Built from durable, weather-resistant materials, the panel complies with Australian traffic sign standards to ensure reliable, long-term performance in challenging outdoor environments.

For worksites requiring motorists to stop at temporary controls, the Prepare To Stop (MMS-ADV-27) sign delivers trusted compliance, high-impact visibility, and dependable durability in one modular panel.
