Road Plant Ahead (Tm1-3-1_a) Multi-Message Sign

The Road Plant Ahead (Tm1-3-1_a) multi-message sign is a 600 × 600 millimetre yellow panel designed to warn motorists that construction machinery or road plant is operating ahead. Commonly used during roadworks, maintenance, and civil projects, this sign gives drivers clear advance notice to slow down, remain alert, and prepare for possible interactions with slow-moving or crossing equipment. Manufactured to meet Queensland Government traffic control requirements, the panel integrates seamlessly with the approved multi-message frame system used throughout the state.

As part of Queensland’s modular multi-message system, the Road Plant Ahead panel can be used on its own or paired with complementary warnings such as “Reduce Speed” or “Prepare To Stop” to create one clear, compliant display. The approved frame supports both 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 ensures councils, contractors, and traffic management providers can update signage quickly as conditions change while staying fully compliant.

Constructed with CL400 Class 1W reflective material in yellow, the Road Plant Ahead panel delivers excellent visibility during the day, at night, and in adverse weather conditions. Its durable, weather-resistant build complies with Australian traffic sign standards, ensuring reliable long-term service in demanding environments. By alerting motorists to the presence of road plant, the sign helps reduce risks, improve driver awareness, and protect both workers and equipment.

For roadworks, civil construction, and maintenance projects, the Road Plant Ahead (Tm1-3-1_a) sign provides trusted compliance, standout visibility, and dependable durability in one modular panel.
