WHAT ARE R100 SERIES COMMAND ROAD SIGNS
R100 Series command road signs are regulatory signs used to instruct road users on actions that must be followed. Their purpose is to direct traffic movement, lane usage, and driving behaviour in a clear and enforceable way.
These signs form part of the standard road signage system defined in the Southern African Development Community Road Traffic Signs Manual (SADC-RTSM) and are used on public roads, private roads, construction sites, and controlled access areas throughout South Africa.
WHEN R100 COMMAND SIGNS ARE USED
R100 Series command signs are used wherever specific driving actions are required to maintain traffic flow, safety, or operational control.
- Where traffic must proceed in a specific direction
- At intersections requiring controlled turning movements
- Where lane discipline must be enforced
- In areas with restricted manoeuvring space
- On private or industrial roads where traffic rules must be clearly communicated
Command signs regulate behaviour directly and must be obeyed. They do not provide guidance or warnings, they instruct mandatory actions.
COMMON ENVIRONMENTS
- Urban and suburban road networks
- Industrial and logistics facilities
- Construction and maintenance zones
- Residential estates and access-controlled areas
- Commercial developments and parking facilities
- Transport hubs and service roads
R100 command signs must be placed where drivers can clearly see and understand the required action before committing to a manoeuvre.
COLOUR, SHAPE, AND SYMBOL MEANING
- Blue circular backgrounds, indicate mandatory instructions
- White arrows or symbols, show the required direction or action
- Circular shape, distinguishes command signs from warning and prohibition signs
This colour and shape combination is prescribed by the SADC-RTSM to ensure instant recognition and consistent interpretation.
COMMON TYPES OF R100 SERIES COMMAND SIGNS
- Turn left only
- Turn right only
- Proceed straight only
- Pass this side
- Directional arrows for controlled movement
The specific sign used depends on road layout, traffic flow requirements, and site conditions. The full range includes variations for different applications.
