The Heavy Vehicles (MMS-ADV-13) multi-message sign is a 600 × 600 millimetre traffic yellow panel designed to warn motorists of the presence of heavy or oversized vehicles on the road. Typically used near construction zones, haul routes, or areas with frequent truck movements, this sign provides advance notice for drivers to exercise caution, reduce speed, and prepare for slower or larger vehicles ahead.
Manufactured in compliance with Western Australia Government traffic control requirements, the panel is fully compatible with the approved modular multi-message frame system. It can be displayed independently or paired with related warnings such as “Truck Crossing” or “Road Works” 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 management providers to update signage quickly and cost-effectively as conditions change.
Constructed with CL400 Class 1W reflective material in traffic yellow, the Heavy Vehicles panel ensures outstanding visibility during the day, at night, and in adverse weather conditions. Its durable, weather-resistant build complies fully with Australian traffic sign standards, providing long-lasting performance in demanding environments.
By alerting drivers to the presence of heavy vehicles, the Heavy Vehicles (MMS-ADV-13) sign enhances road safety, reduces the likelihood of accidents, and supports effective traffic management in high-risk zones.
