What these signs are used for
R100 Series Command Signs are used to direct compulsory movements or actions, such as turning, lane use, or route compliance.
How they are visually identified
Their blue circular format with white symbols provides immediate recognition of mandatory instructions.
Materials and design proportions
Designs follow fixed layouts and proportions defined in the Manual, with reflective signfaces to support visibility in day and night conditions.
Approved sizes
Approved sizes vary by sign type and road classification, with dimensions selected to ensure adequate viewing distance and reaction time.
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 R100 sign code first, then confirm size and reflective performance based on traffic speed, approach distance, and installation location.
