South African Learner Driver Manual: Road Traffic Signs
Copyright and Disclaimer
The South African Learner Driver Manual is compiled by the Department of Transport of the Republic of South Africa and is intended for educational purposes to regulate traffic in a manner that promotes traffic flow and road safety. The manual is copyright © 2012 by the SA Department of Transport.
1. Purpose of Road Traffic Signs
Traffic signs are essential for promoting road safety and effective traffic flow. They are categorized into six main groups:
1.1 Types of Signs
- Regulatory Signs (Ordinary Shape): These dictate actions of road users and violations result in legal consequences. The shape is typically round.
- Warning Signs (Triangular): These alert drivers about potential hazards on or beside the road.
- Guidance Signs (Rectangular): These assist in navigation, ranging from simple to complex messages.
- Information Signs (Rectangular): These provide general information to drivers.
- Road Markings: These define lanes and direct traffic flow, with disregard resulting in penalties similar to regulatory signs.
- Traffic Signals: These manage both vehicular and pedestrian traffic. Non-compliance leads to penalties.
2. Sign Classification
2.1 Regulatory Signs Categories
Regulatory signs can be subdivided into several categories:
- Control Signs: E.g., stop signs.
- Command Signs: Indicate required actions.
- Prohibition Signs: Indicate forbidden actions.
- Reservation Signs: Reserved for specific vehicle types.
- Comprehensive Signs: Contain complex information.
- Selective Restriction Signs: Limits access based on vehicle type.
- Combination Signs: Feature both regulatory and informational aspects.
- De-restriction Signs: Indicate an end to previous restrictions.
3. Detailed Description of Signs
3.1 Control Signs
- Stop Sign (R1.1): Found at intersections and railway crossings. Drivers must stop behind the stop line and only proceed when safe.
- Yield Sign (R2): At intersections, instructs drivers to give way to crossing traffic.
- 3-Way and 4-Way Stop Signs (R1.3 & R1.4): Direct traffic control at multi-directional intersections; the vehicle that stops first moves first.
- STOP/RY-GO Sign (R1.5): Found at road works; indicates when to stop or proceed based on displayed signals.
3.2 Command Signs
- Minimum Speed Sign (R101): Sets a minimum speed limit to prevent slow vehicles from disrupting traffic.
- Vehicles Exceeding Mass Only (R102): Indicates routes designated for heavier vehicles.
- Keep Left (R103) / Keep Right (R104): Directs drivers around obstructions.
- Prohibition of Specific Vehicle Types: Signs like “Taxis Only (R118)” dictate vehicle access on specific roads.
3.3 Prohibition Signs
- Speed Limit (R201): Indicates the maximum permissible speed; compliance is mandatory.
- Mass Limit (R202): Restricts heavy vehicles according to their gross vehicle mass; non-compliance leads to penalties.
- No Overtaking Signs (R214): Prohibits overtaking for the specified distance ahead.
3.4 Reservation Signs
- Bus Lane Reservation (R302): Identifies lanes allocated for bus use only; enforced during designated times.
- Parking Reservation Signs: Designate areas reserved for specific vehicle types such as emergency vehicles.
3.5 Comprehensive Signs
- Dual-carriageway Freeway Begins (R401): Marks the start of a freeway, mandating adherence to specific freeway rules.
4. Warning Signs
4.1 Road Layout Signs
- Crossroad Sign (W101): Alerts the driver to an intersection ahead.
- Priority Crossroad (W102): Indicates which road has the right of way at intersections.
- Sharp Junction Signs (W112): Warns of merging traffic at sharp angle junctions.
4.2 Direction of Movement Signs
- Traffic Circle Sign (W201): Warns of a traffic circle ahead, signaling potential yielding based on the right-of-way rule.
5. Information Signs
These signs provide additional navigation details and regulations.
- Countdown Signs: Indicate proximity to exits (300m, 200m, 100m).
- Right-of-Way Signs: Inform drivers about intersections granting them the right to proceed.
6. Road Markings
6.1 Regulatory Markings
- Stop Line (RTM1): Indicates where vehicles must halt, particularly at intersections and crossings.
- Yield Line (RTM2): Indicates priority at intersections to enhance pedestrian safety.
7. Traffic Signals
Traffic lights regulate vehicular and pedestrian movement through a system of lights:
- Red: Stop.
- Amber: Prepare to stop; if nearing an intersection and unable to stop safely, proceed with caution.
- Green: Proceed if safe.
- Flashing Lights: Indicate special instructions such as yielding.
Summary
The South African Learner Driver Manual provides comprehensive guidelines on road traffic signs, aimed to govern and direct road user behavior to ensure safety and efficient traffic flow. Each sign has specific purposes, actions, and imposed legal implications for non-compliance, thereby creating structured road use for all participants.
