Left Lane Open (TC1359-5) – Multi-Message Sign

The Left Lane Open (TC1359-5) multi-message sign is a 600 × 600 millimetre traffic yellow regulatory panel designed to inform motorists that the left lane is open for travel. This sign provides a clear, enforceable advisory to guide drivers safely through work zones, lane diversions, or traffic management areas, improving traffic flow and reducing confusion. 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 Open 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 flexible configurations, 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 modular design allows councils, contractors, and traffic management providers to adapt signage efficiently to suit site-specific conditions.

Produced with CL400 Class 1W reflective material in traffic yellow, the Left Lane Open panel ensures excellent visibility during daylight, nighttime, and adverse weather. 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 indicating lane availability, the sign promotes smoother traffic flow, safer lane usage, and reduced driver confusion.

For roadworks, temporary lane diversions, and traffic management, the Left Lane Open (TC1359-5) sign provides trusted compliance, high-visibility performance, and durable construction in one modular panel.
