The Road Plant Ahead (MMS-ADV-34) multi-message sign is a 600 × 600 millimetre traffic yellow panel designed to alert motorists of construction plant or heavy equipment operating on the roadway ahead. Commonly deployed during resurfacing, grading, or road maintenance works, this sign provides advance notice for drivers to reduce speed, exercise caution, and prepare for slow-moving vehicles or altered traffic conditions.
Manufactured in compliance with Western Australia Government traffic control requirements, the panel integrates seamlessly into the approved modular multi-message frame system. It can be displayed independently or paired with related warnings such as “Grader Ahead” or “Heavy Vehicles” to form 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 allows councils, contractors, and traffic managers to update signage quickly and cost-effectively as conditions change.
Constructed with CL400 Class 1W reflective material in traffic yellow, the Road Plant Ahead panel delivers excellent visibility during daylight, at night, and in adverse weather. Its durable, weather-resistant design complies fully with Australian traffic sign standards, ensuring long-term performance under tough outdoor conditions.
By warning of road plant activity, the Road Plant Ahead (MMS-ADV-34) sign improves driver awareness, reduces accident risks, and supports safe traffic management in active work zones.
