Product Description
Beginning of Dual Roadway (To Left) Ahead – W119 Road Sign
The W119 Beginning of Dual Roadway (To Left) Ahead road sign is a warning sign used to alert drivers that a two-way roadway is about to change to a divided roadway arrangement. A physical median island will begin ahead, separating opposing directions of traffic into one-way roadways.
W119 is used where the roadway being signed deviates to the left from the principal alignment of the approach road at the point where the median island begins.
What Does the W119 Road Sign Mean?
W119 means Beginning of Dual Roadway (To Left) Ahead. It warns drivers that the current two-way roadway is approaching a point where a physical median island will commence and traffic will be separated into one-way roadways.
The sign provides advance information about the upcoming change in road layout. It does not itself impose a speed limit or require drivers to stop.
Drivers must continue to follow all applicable speed-limit signs, regulatory signs, lane markings, road markings and other traffic-control instructions.
What Is a Dual Roadway?
A dual roadway is a divided roadway where traffic travelling in opposite directions uses separate one-way roadways.
The separation is normally provided by a physical median island or another suitable form of physical separation. Before the division begins, traffic may operate in both directions on the same roadway.
W119 warns drivers about this transition and indicates that the roadway being signed will deviate to the left as the median island commences.
What Does “To Left” Mean on W119?
The “To Left” description refers to the road alignment represented by the warning sign.
According to the South African Road Traffic Signs Manual, W119 is used where the median island commences and the roadway being signed deviates to the left of the principal alignment of the approach road, whether the approach is straight or curved.
This is different from W118 Beginning of Dual Roadway (Straight On), which applies where the roadway follows the principal alignment of the approach road.
Where Are W119 Signs Used?
W119 signs may be used in advance of locations where a two-way roadway changes to divided-road operation and the signed roadway deviates to the left as the median island begins.
Potential applications include:
- Dual-carriageway roads
- Highways
- Freeway approaches
- Divided urban roads
- Rural divided roads
- Roads where a central median begins
- New or upgraded road infrastructure
- Road construction projects
- Traffic-management projects
- Temporary road layouts during construction
Why Is the W119 Warning Sign Important?
The beginning of a dual roadway changes the way opposing traffic is separated. Drivers approaching the transition need to recognise that the road layout is changing and that a physical median will begin ahead.
W119 provides advance warning of this change, particularly where the roadway being travelled on deviates from the principal alignment of the approach road.
This can help drivers prepare for the new lane arrangement and the position of the median island.
How Should Drivers Respond to a W119 Sign?
Drivers approaching a W119 sign should remain alert to the upcoming change from two-way traffic to divided-road operation.
Drivers should:
- Adjust their speed to the road and traffic conditions.
- Watch for the beginning of the median island.
- Follow lane and road markings carefully.
- Remain in the correct lane.
- Observe applicable speed-limit signs.
- Watch for vehicles changing lanes or merging.
- Follow any additional traffic-control signs provided at the transition.
W119 Sign Placement
The W119 sign should be displayed sufficiently in advance of the point where the dual roadway begins so that drivers have enough time to recognise the warning and prepare for the change in road arrangement.
The sign should be positioned in accordance with the applicable advance-warning distances and adjusted where the geometry of the road requires special treatment.
Visibility, operating speed, road alignment and surrounding conditions should all be considered when determining the appropriate location.
The sign should be clearly visible to approaching traffic and should not be obstructed by vegetation, buildings, advertising boards or other roadside objects.
W119 Sign Design and Colours
The permanent W119 warning sign uses the standard South African warning-sign colour arrangement:
- Triangle: Red retroreflective
- Symbol: Black semi-matt
- Background: White retroreflective
A temporary version, TW119, is also specified. Temporary warning signs use a red retroreflective triangle, black semi-matt symbol and yellow retroreflective background.
W119 and W118
W118 and W119 both warn that a dual roadway is about to begin, but they represent different road alignments.
- W118: Beginning of Dual Roadway (Straight On) Ahead.
- W119: Beginning of Dual Roadway (To Left) Ahead.
W118 is used where the roadway being signed follows the principal alignment of the approach road. W119 is used where the roadway being signed deviates to the left from that principal alignment.
The actual road geometry should therefore be considered when selecting the appropriate sign.
W119 During Roadworks
The temporary TW119 sign may be particularly appropriate during roadworks where traffic is temporarily returned to a normal dual-roadway arrangement through a median island.
Temporary warning signs should form part of the wider temporary traffic-management system and may need to be used together with other warning, regulatory and direction signs appropriate to the work zone.
W119 Compared with End of Dual Roadway Signs
W119 warns about the beginning of a dual roadway, while W116 and W117 warn about the end of a dual roadway.
- W116: End of Dual Roadway (To Right).
- W117: End of Dual Roadway (Straight On).
- W118: Beginning of Dual Roadway (Straight On).
- W119: Beginning of Dual Roadway (To Left).
These signs describe different transitions in the road layout and should be selected according to the actual geometry at the location.
W119 Is Not a Road-Narrows Sign
W119 is specifically intended to warn about the beginning of a dual roadway. It should not be used simply to indicate that an undivided roadway becomes narrower.
Where the actual hazard is a narrowing of an undivided roadway, the appropriate road-narrows warning sign should be selected instead.
W119 Signs in South Africa
The W119 Beginning of Dual Roadway (To Left) Ahead sign forms part of the South African road traffic warning-sign system.
Where W119 is used on a public road, its design, application, placement and installation should follow 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 arrangement.

W119 signage may be relevant to organisations involved in road construction, infrastructure development and traffic management, including:
- Municipalities
- Road authorities
- Road construction contractors
- Traffic-management contractors
- Highway and freeway contractors
- Infrastructure developers
- Road maintenance teams
