900x1200mm- Class 1 – Aluminium – 90 km Speed Restriction in Roundel

The R4-1C(90) delivers premium speed limit communication engineered for high-speed road environments requiring maximum advance warning and visibility. This 900x1200mm regulatory sign prominently displays the 90 km/h speed restriction within the iconic red roundel format, dimensioned specifically to ensure drivers traveling at higher speeds receive adequate distance to comprehend and respond to the speed restriction. Manufactured from heavy-gauge 1.6mm aluminium alloy and laminated with Class 1 high-intensity reflective vinyl, this sign maintains exceptional visibility across all lighting and weather conditions encountered in Australian road environments. The substantial format proves particularly valuable on roads where advance speed communication is essential for safety, allowing drivers sufficient reaction time and distance to adjust their speed appropriately before entering the restricted zone. The Class 1 reflective technology employs microprismatic elements creating brilliant light return characteristics when struck by vehicle headlights, maintaining sign clarity during nighttime operation, in adverse weather including fog and rain, and when viewed from oblique angles or extended distances. The aluminium construction provides superior longevity, resisting corrosion, warping, impact damage, and environmental degradation while maintaining professional appearance through years of continuous outdoor exposure. Weather-resistant graphics and UV-stabilized materials prevent fading ensuring speed limit numerals remain sharp and highly legible throughout extended operational life. Pre-drilled mounting holes accommodate standard Australian traffic sign posts and mounting systems for secure compliant installation. Full AS1742 compliance makes this sign approved for public road use and suitable for private applications requiring regulatory-grade traffic management signage.
