What these signs are used for
W100 Series Road Layout Warning Signs are used to alert drivers to bends, curves, junctions, and changes in road alignment that require increased attention.
How they are visually identified
The triangular shape with a red border is universally recognised as a warning, allowing rapid identification.
Materials and design proportions
Designs follow fixed layouts and proportions defined in the Manual, with reflective signfaces to support visibility in all lighting conditions.
Approved sizes
Approved sizes vary by sign type and road classification, with dimensions selected to ensure adequate warning distance based on speed and approach conditions.
These signs are manufactured in accordance with SADC-RTSM and are aligned with internationally recognised road signage principles, including SANS 1519 for retroreflective signface materials.
Selection and compliance guidance
Select the correct W100 sign code first, then choose a size and reflective performance appropriate to the road speed and visibility conditions.
