Left Lane Closed (TC1359-8) – Multi-Message Sign

The Left Lane Closed (TC1359-8) multi-message sign is a 600 × 600 millimetre traffic yellow regulatory panel designed to warn motorists that the left lane ahead is closed. This sign provides a clear, enforceable advisory for drivers to merge safely, reduce speed, and remain alert to lane changes to prevent collisions. 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 Left Lane Closed panel can be displayed on its own or paired with complementary warnings such as “Merge Right,” “Reduced Speed,” or “Traffic Incident Ahead” to form one compliant display. The approved frame supports versatile 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 modularity allows councils, contractors, and traffic management providers to adapt signage quickly to changing road conditions.

Produced with CL400 Class 1W reflective material in traffic yellow, the Left Lane Closed panel ensures excellent visibility during daylight, nighttime, and adverse weather conditions. Its durable, weather-resistant construction fully complies with Australian traffic sign standards, delivering reliable long-term performance on highways, urban roads, and temporary traffic management zones. By clearly warning drivers of lane closures, the sign promotes safer lane changes, reduces congestion, and enhances overall road safety.

For roadworks, temporary lane closures, and traffic management, the Left Lane Closed (TC1359-8) sign provides trusted compliance, high-visibility performance, and durable construction in one modular panel.
