The Rough Surface (MMS-RC-5) multi-message sign is a 600 × 600 millimetre traffic yellow panel designed to warn motorists of uneven or deteriorated road surfaces. Commonly used during or after resurfacing, grading, or maintenance works, this sign provides advance notice for drivers to reduce speed, maintain control, and exercise caution on unstable or irregular road conditions.
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 “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 design enables councils, contractors, and traffic managers to update signage quickly and cost-effectively as site conditions change.
Constructed with CL400 Class 1W reflective material in traffic yellow, the Rough Surface panel delivers excellent visibility in daylight, at night, and during adverse weather conditions. Its durable, weather-resistant build complies fully with Australian traffic sign standards, providing reliable long-term performance in harsh outdoor environments.
By alerting drivers to uneven surfaces, the Rough Surface (MMS-RC-5) sign improves awareness, reduces accident risks, and enhances overall safety in areas with temporary or compromised road conditions.
