Power Line Works In Progress (TC9916-1) – Multi-Message Sign

The Power Line Works In Progress (TC9916-1) multi-message sign is a 600 × 600 millimetre traffic yellow regulatory panel designed to alert motorists and pedestrians to ongoing electrical and overhead power line maintenance. This sign provides a clear, enforceable advisory to exercise caution, reduce speed, and remain vigilant in areas where crews are working near or above the roadway. Manufactured to Queensland Government traffic control requirements, the panel integrates seamlessly with the state-approved multi-message frame system.

As part of Queensland’s modular multi-message system, the Power Line Works In Progress panel can be displayed on its own or paired with complementary warnings such as “Prepare To Stop,” “Detour Ahead,” or “Changed Traffic Conditions” to create one compliant display. The approved frame allows for flexible layouts, including two 600 × 600 millimetre panels above a 1200 × 300 millimetre panel, or a single 1200 × 600 millimetre panel above with the same 1200 × 300 millimetre panel beneath. This adaptability enables councils, contractors, and traffic management providers to update signage quickly as conditions change.

Produced with CL400 Class 1W reflective material in traffic yellow, the Power Line Works In Progress panel ensures superior visibility during daylight, nighttime, and adverse weather. Its durable, weather-resistant construction complies fully with Australian traffic sign standards, delivering long-term reliability in demanding environments. By clearly warning of overhead works, the sign improves awareness, reduces risks to motorists and workers, and supports safer traffic management.

For electrical maintenance zones, roadworks involving overhead assets, and temporary traffic management, the Power Line Works In Progress (TC9916-1) sign provides trusted compliance, high-visibility performance, and durable construction in one modular panel.
