Speed Bump Ahead (TC1668) – Multi-Message Sign

The Speed Bump Ahead (TC1668) multi-message sign is a 600 × 600 millimetre traffic yellow regulatory panel designed to warn motorists of upcoming speed bumps or humps on the roadway. This sign provides a clear, enforceable advisory to reduce speed, ensuring safe passage over traffic-calming measures and minimizing the risk of vehicle damage or loss of control. 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 Speed Bump Ahead panel can be displayed on its own or paired with complementary warnings such as “Reduce Speed,” “Next ___ m,” or “Pedestrian Crossing” to form one compliant display. The approved frame supports 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 modularity allows councils, contractors, and traffic management providers to adjust signage quickly to suit changing site conditions.

Produced with CL400 Class 1W reflective material in traffic yellow, the Speed Bump Ahead panel ensures excellent visibility during daylight, nighttime, and adverse weather conditions. Its durable, weather-resistant construction fully complies with Australian traffic sign standards, providing long-term performance in urban streets, construction zones, and temporary traffic management areas. By clearly alerting drivers in advance, the sign promotes safer driving, controlled traffic flow, and reduced risk of accidents.

For traffic calming, pedestrian safety, and temporary roadworks, the Speed Bump Ahead (TC1668) sign delivers trusted compliance, high-visibility performance, and durable construction in one modular panel.
