The Roundabout Sign (R1-3B), measuring 900mm in diameter, is designed to notify drivers of an approaching roundabout, ensuring they reduce speed and prepare to yield as necessary. Made with Class 1 reflective (CL1) material, this sign offers superior visibility in all lighting and weather conditions. Built to meet R1-3B Australian standards, it is suitable for installation at roundabout entrances on highways, high-traffic areas, or locations requiring enhanced driver awareness. Constructed for durability and long-lasting outdoor performance, this sign is an essential component of effective traffic management and road safety compliance.
