The Rough Surface (MMS-RC-13) multi-message sign is a 600 × 600 millimetre traffic yellow panel designed to warn motorists of uneven or deteriorated road surfaces ahead. Typically used following resurfacing, patching, or maintenance works, this sign provides drivers with advance notice to reduce speed, maintain control, and exercise caution when navigating unstable or irregular surfaces.
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 warnings such as “Loose Surface” or “No Lines” 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 site conditions evolve.
Constructed with CL400 Class 1W reflective material in traffic yellow, the Rough Surface panel ensures high visibility during daylight, at night, and in adverse weather. Its durable, weather-resistant design complies with Australian traffic sign standards, ensuring long-term reliability in challenging outdoor environments.
By warning of hazardous road conditions, the Rough Surface (MMS-RC-13) sign enhances driver awareness, reduces the risk of accidents, and supports safer travel through work zones or maintenance areas.
