Sharp Junction (Half Left) Ahead – W111 Road Sign

The W111 Sharp Junction (Half Left) Ahead road sign is a warning sign used to alert drivers that a sharp junction is approaching, with the junction arrangement shown by the sign requiring attention to the left side of the road layout.

The sign provides advance warning of a potentially hazardous junction where joining or leaving traffic, or restricted sight distance, may make the junction dangerous or potentially dangerous. It allows drivers to prepare for the road layout and approach the junction with greater care.

What Does the W111 Road Sign Mean?

The W111 sign warns drivers of a sharp junction ahead in the half-left configuration represented by the sign symbol.

W111 is a warning sign. It does not itself require a driver to stop or give way. Where a stop sign, yield sign, traffic signal, road marking or other traffic-control measure applies at the junction, drivers must follow that instruction.

What Is a Sharp Junction?

A sharp junction is a junction with an arrangement or geometry that can require drivers to make a significant change in direction or deal with traffic entering or leaving the road in a way that may create a dangerous or potentially dangerous situation.

The South African Road Traffic Signs Manual indicates that the W111, W112, W113 and W114 warning signs are used where joining or leaving traffic, or restricted sight distance, may make the sharp junction ahead dangerous or potentially dangerous.

Where Are W111 Signs Used?

W111 signs may be used on approaches to sharp junctions where advance warning is needed to alert drivers to the unusual junction arrangement.

Potential applications include:

• Urban roads
• Suburban roads
• Rural roads
• Residential areas
• Commercial developments
• Industrial areas
• Estate roads
• Junctions with restricted sight distance
• Roads where vehicles join or leave the main route at a sharp junction
• Locations where the junction layout may not be immediately obvious

Why Is a W111 Warning Sign Important?

A sharp junction can require drivers to respond to a changing road direction while also watching for vehicles entering or leaving the roadway.

Advance warning gives approaching road users an opportunity to recognise the junction and adjust their driving before reaching it.

This can be particularly useful where vegetation, buildings, curves, road geometry or other conditions restrict the driver's view of the junction.

How Should Drivers Respond to a W111 Sign?

Drivers approaching a W111 sign should remain alert and prepare for the sharp junction ahead.

Drivers should:

• Adjust their speed to the road and traffic conditions.
• Watch carefully for vehicles entering or leaving the junction.
• Look for stop, yield or other regulatory signs.
• Follow traffic signals and road markings.
• Be prepared to stop where required.
• Maintain control of the vehicle when negotiating the junction.
• Watch for pedestrians, cyclists and other road users.

W111 Sign Placement

The appropriate sharp-junction warning sign should normally be located on the road that has priority at the junction. Where the approach is controlled by a STOP sign R1 or a YIELD sign R2, the appropriate sharp-junction warning sign may also be used in addition to the control sign.

The sign should be positioned sufficiently in advance of the junction to give approaching drivers adequate time to recognise the warning and prepare for the road layout.

Placement should take into account operating speed, sight distance, road alignment, visibility and surrounding roadside conditions. The sign should remain clearly visible to approaching traffic.

W111 Sign Design and Colours

The permanent W111 warning sign uses a triangular warning-sign design with a red retroreflective triangle, black semi-matt symbol and white retroreflective background.

A temporary version, TW111, is available for temporary sharp-junction arrangements at roadworks. Temporary sharp-junction warning signs use a red retroreflective triangle, black semi-matt symbol and yellow retroreflective background.

W111 and Other Sharp Junction Signs

W111 forms part of a group of South African sharp-junction warning signs. The correct sign should be selected according to the actual junction layout.

• W111: Sharp Junction (Half Left) Ahead.
• W112: Corresponding half-right sharp-junction arrangement.
• W113: Another sharp-junction arrangement represented by its symbol.
• W114: The corresponding opposite arrangement to W113.

Using the correct symbol is important because the warning should accurately represent the road layout ahead.

W111 at Freeway On-Ramp Junctions

The South African Road Traffic Signs Manual notes that W112 is commonly used to warn drivers of a freeway on-ramp junction with the main freeway carriageway. Sharp-junction warning signs can also apply to sharp junctions on two-way roads.

W111 should therefore be selected according to the actual junction arrangement rather than being used simply because a road contains a sharp curve.

W111 Compared with Curve Warning Signs

W111 should not be confused with a general curve or bend warning sign. A curve warning sign is intended to warn about a change in road alignment, while W111 specifically warns about a sharp junction.

This distinction is important when selecting road signage because the correct warning should describe the actual hazard or road layout that drivers are approaching.

W111 Signs in South Africa

The W111 Sharp Junction (Half Left) Ahead sign forms part of the South African road traffic warning-sign system. Public-road warning signs should be selected, manufactured and installed according to the applicable South African road traffic sign standards and the requirements of the responsible road authority.

Similar warning signage may also be used on private roads, residential estates, commercial properties, industrial sites and other controlled areas where it forms part of an appropriate internal traffic-management system.

W111 signage may be relevant to organisations involved in road construction, property development and traffic management, including:

• Municipalities
• Road authorities
• Road construction contractors
• Traffic-management contractors
• Property developers
• Residential estates
