Do Not Overtake Signs for NSW – Stay Compliant on the Road
In New South Wales, Do Not Overtake Turning Vehicle signs have specific requirements that differ from other Australian states. Unlike the rest of Australia, NSW mandates that the text on the left-hand marker must be at least 50mm high. This means that even though other states have moved away from the traditional 400mm x 400mm marker size, NSW still requires this larger format to accommodate the larger lettering.
Many trucks and trailers across the country still display the older 400mm square markers. However, most of these signs use Class 2 reflective finishes, which no longer comply with current standards. Today, only Class 1 (Class 400) reflective markers are accepted for use in NSW.
At National Safety Signs, we stock a full range of Do Not Overtake Turning Vehicle signs that meet NSW requirements, including 400mm square markers with Class 400 reflective material for maximum visibility and compliance.
Options for Trucks and Trailers
For trailers with limited space, we supply metal versions of the Do Not Overtake sign, which can be mechanically fixed to the vehicle. We also offer long, narrow adhesive strips, such as the 1800mm wide Class 400 reflective strip (supplied in two halves for easy installation). These options provide flexibility, ensuring you remain compliant no matter the size or layout of your vehicle.
