R & W Series High Visibility
R and W Series High Visibility Road Signs are standardised road signs defined under the SADC Road Traffic Signs Manual (SADC-RTSM) to improve sign conspicuity and recognition in high-risk or reduced-visibility conditions.
Standard sizes and materials are available for online purchase. Alternative sizes, materials, or specifications can be supplied on request.
To enquire about additional products such as nuts, bolts, clamps, unistruts, treated timber poles, and galvanised or painted steel poles in either round or square tubing, please contact us via email at info@safetysignonline.co.za.
What these signs are used for
R and W Series High Visibility Signs are used where additional emphasis is required, such as high-speed roads, complex junctions, or locations with a history of incidents.
How they are visually identified
They retain the recognised R or W series format while incorporating high-visibility backgrounds or borders to attract attention earlier.
Materials and design proportions
Design proportions follow the underlying sign series, with enhanced reflective materials used to increase luminance and conspicuity.
Approved sizes
Approved sizes match those specified for the equivalent R or W sign codes, selected based on approach speed, viewing distance, and risk level.
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
Confirm the underlying R or W sign code first, then determine whether enhanced visibility is appropriate for the road environment and hazard profile.
