Product Description

Sharp Junction (Left) Ahead – W112 Road Sign

The W112 Sharp Junction (Left) Ahead road sign is a warning sign used to alert drivers to a sharp junction where the road layout requires particular attention to a junction or sharp connection on the left.

The sign provides advance warning of a potentially hazardous junction arrangement, giving drivers time to become alert to the road layout and prepare for traffic movements at the junction.

What Does the W112 Road Sign Mean?

The W112 sign warns drivers of a sharp junction from the left ahead.

It is a warning sign and does not by itself require a driver to stop or give way. Drivers must continue to observe any applicable stop signs, yield or give-way signs, traffic signals, road markings and other traffic-control instructions at the junction.

What Is a Sharp Junction?

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

The W112 sign is part of the South African group of sharp-junction warning signs. These signs are intended to draw attention to junction layouts that may require additional care from approaching drivers.

Where Are W112 Signs Used?

W112 signs may be used on approaches to sharp junctions where advance warning is necessary because of the road layout, joining or leaving traffic, or restricted sight distance.

Potential applications include:

• Urban roads
• Suburban roads
• Rural roads
• Intersections with unusual road geometry
• Junctions with restricted visibility
• Freeway interchange areas
• Interchange on-ramp junctions
• Systems interchange ramp junctions
• Commercial developments
• Industrial and private road networks

W112 at Freeway Interchanges

The South African Road Traffic Signs Manual specifically identifies W112 Sharp Junction from Left as a warning sign that may be required at a freeway interchange on-ramp or at a junction of two ramps on a systems interchange.

This makes the sign particularly relevant to road layouts where ramps connect or merge in a way that may not be immediately clear to approaching drivers.

Why Is a W112 Warning Sign Important?

A sharp junction can present drivers with an unusual change in road direction or unexpected traffic movements. Advance warning helps drivers recognise that the junction ahead requires additional attention.

The warning may be particularly useful where the junction has limited visibility or where the road geometry makes the intersection difficult to recognise from a distance.

How Should Drivers Respond to a W112 Sign?

Drivers approaching a W112 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.
• Observe stop and give-way signs.
• Follow traffic signals and road markings.
• Be prepared to stop where required.
• Maintain control of the vehicle through the junction.
• Watch for pedestrians, cyclists and other road users where applicable.

W112 Sign Placement

The sign should be positioned in advance of the sharp junction so that approaching drivers have adequate time to recognise the warning and prepare for the road layout.

Placement should take account of the road alignment, operating speed, sight distance, visibility and surrounding conditions.

The sign should remain clearly visible to approaching traffic and should not be obstructed by vegetation, buildings, advertising boards or other roadside objects.

W112 Sign Design and Colours

The permanent W112 warning sign uses a triangular warning-sign design with a red retroreflective triangle, black semi-matt symbol and white retroreflective background.

A temporary version, TW112, is also specified for temporary applications. Temporary warning signs use a red retroreflective triangle, black semi-matt symbol and yellow retroreflective background.

W112 and Other Sharp Junction Signs

W112 forms part of a series of sharp-junction warning signs in the South African road-sign system.

• W111: Sharp Junction (Half Left)
• W112: Sharp Junction (Left)
• W113: Sharp Junction (Half Right)
• W114: Sharp Junction (Right)

The correct sign should be selected according to the actual road layout represented by the warning symbol.

W112 Compared with General Curve Warning Signs

W112 should not simply be treated as a general sharp-bend or sharp-curve warning sign. Its purpose is to warn about a sharp junction and the associated road layout.

Where the hazard is a change in road alignment without a junction, an appropriate curve or bend warning sign should be considered instead.

W112 Signs in South Africa

The W112 Sharp Junction (Left) sign forms part of the South African road traffic warning-sign system. Public-road 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.

W112 signage may be relevant to organisations involved in road construction, traffic management and property development, including:

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

• Freeway and interchange projects
