3-Way Stop Sign – R1.3

A 3-Way Stop Sign, identified as R1.3 in the South African road-sign system, is a regulatory traffic sign used where all-way stop control is required at a three-leg road junction. It requires drivers approaching the controlled junction to stop before proceeding.

The R1.3 sign is a derivative of the standard R1 Stop Sign. The South African Road Traffic Signs Manual specifies R1.3 for three-leg junctions where all-way stop control is required.

What Does a 3-Way Stop Sign Mean?

A 3-Way Stop Sign means that traffic approaching the controlled junction from the three designated approaches is subject to a stop requirement.

Drivers must bring their vehicles to a complete stop at the applicable stopping position and may proceed only when it is safe and permitted to do so. The stop requirement associated with R1.3 is the same mandatory requirement that applies to the standard R1 Stop Sign.

Drivers should also observe road markings, other traffic signs, pedestrians, cyclists and approaching vehicles before proceeding through the junction.

What Is the R1.3 3-Way Stop Sign?

R1.3 is the South African regulatory sign designation for a 3 WAY-STOP sign. It is intended for a three-leg road junction where all-way stop control is required.

The sign is different from a standard R1 Stop Sign because it communicates that the stop control applies to the three approaches forming part of the controlled junction.

The South African Road Traffic Signs Manual also identifies R1.4 as the corresponding 4-Way Stop derivative for four-leg road junctions.

How Does a 3-Way Stop Work?

At an R1.3 controlled junction, drivers approaching from each of the three designated approaches are required to stop.

After stopping, drivers must assess the intersection and proceed only when it is safe and permitted under the applicable traffic rules. Drivers should not enter the junction simply because they have stopped first if another road user has already entered or has priority under the applicable rules.

Where several vehicles arrive at approximately the same time, drivers should proceed cautiously and follow the applicable right-of-way rules rather than assuming that arrival order alone determines priority.

Where Are 3-Way Stop Signs Used?

An R1.3 3-Way Stop Sign may be used at suitable three-leg road junctions where an all-way stop-control arrangement is required.

Potential applications can include:

• Three-leg road junctions
• T-junctions requiring all-way stop control
• Residential developments
• Private estates
• Business parks
• Industrial properties
• Commercial developments
• Shopping-centre access roads
• Large private parking and access areas
• Other suitable three-approach junctions

On public roads, the use of an R1.3 sign should be determined in accordance with the applicable road-traffic requirements and the requirements of the responsible road or traffic authority.

3-Way Stop Signs at T-Junctions

A T-junction is one example of a three-leg road junction where an R1.3 arrangement may be considered when all-way stop control is required.

Each controlled approach must be clearly identified so that drivers understand that they are required to stop before proceeding through the junction.

Sign visibility, stopping positions, road markings and the overall road layout should be considered together when planning the traffic-control arrangement.

Why Are 3-Way Stop Signs Used?

A 3-Way Stop Sign can provide a clear regulatory instruction where traffic from three approaches needs to be controlled by an all-way stop arrangement.

The stop requirement gives drivers an opportunity to stop before entering the junction, observe other traffic and road users, and proceed when it is safe and permitted to do so.

The South African Road Traffic Signs Manual notes that the use of all-way stop signs should be carefully assessed because of their effect on traffic, and that R1 and its derivatives should receive careful consideration when selecting traffic control for a junction.

3-Way Stop Sign Placement

Correct positioning is important so that approaching drivers can identify the R1.3 sign before reaching the controlled junction.

The sign should be positioned with consideration for the road layout, approaching traffic, stopping position and visibility. Trees, buildings, parked vehicles, advertising structures and other objects should not unnecessarily obstruct the sign.

Road markings and other traffic-control devices should also be considered as part of the complete junction arrangement.

R1.3 3-Way Stop Sign on Private Property

3-Way Stop arrangements may also be considered for internal roads and access routes on private property where traffic movements need to be controlled.

Potential private-property applications include:

• Shopping centres
• Business parks
• Factories and industrial sites
• Warehouses
• Residential estates
• Office developments
• Private parking facilities
• Commercial properties
• Large internal road networks

For private-property installations, the traffic-control arrangement should be appropriate for the site's road layout and traffic-management requirements. Property owners and site managers should also consider any applicable requirements when introducing regulatory-style traffic control on private roads.

R1.3 3-Way Stop Sign in South Africa

The R1.3 designation forms part of the South African regulatory road-sign system. The Department of Transport's South African Road Traffic Signs Manual identifies R1.3 as the 3 WAY-STOP sign for all-way stop control at a three-leg road junction.

The standard R1 Stop Sign requires a driver to stop at the applicable stopping position and not proceed until it is safe to do so. The manual states that R1.3 has the same mandatory requirements as R1.

Public-road installations should therefore use the appropriate specification and be implemented in accordance with the requirements of the responsible road or traffic authority.

Stop (3-way) signs come in a variety of styles and formats, including danger signs, warning signs, and caution signs. Danger signs are used to indicate an immediate threat that could cause serious injury or death, such as high voltage areas or hazardous materials. Warning signs are used to indicate potential hazards that could cause injury, such as slippery floors or falling objects. Caution signs are used to indicate potential hazards that could cause minor injury, such as low ceilings or uneven surfaces. Another type of safety sign is the Stop (3-way) sign, which is used to provide guidance on safe behavior. These signs can include instructions on how to use equipment or machinery safely, as well as reminders to wear personal protective equipment (PPE) or follow specific safety protocols. Stop (3-way) signs can also be used to ensure compliance with safety regulations. For example, fire safety signs are required by law in most public buildings and workplaces. These signs indicate the location of fire exits, fire extinguishers, and other fire safety equipment.

Healthcare facilities may use signs to remind employees to wash their hands or to indicate the location of first aid supplies. When selecting safety signs, it is important to choose signs that are appropriate for the specific hazard or situation. Signs should be placed in prominent locations where they are easily visible, and should be made from durable materials that can withstand harsh environmental conditions. By using safety signs effectively, businesses and organizations can help protect their employees, customers, and visitors from harm.
