Staggered Side-Road Junctions Ahead – W110 Road Sign

The W110 Staggered Junctions (L-R) Ahead road sign is a warning sign used to alert drivers that closely situated side-road junctions are approaching in a staggered arrangement. The W110 symbol represents the left-right (L-R) staggered junction arrangement.

The warning gives approaching drivers advance information that they may encounter two side-road junctions within a relatively short distance. This allows drivers to remain alert for traffic entering or leaving the road from both sides.

What Does the W110 Road Sign Mean?

The W110 sign warns drivers about staggered side-road junctions ahead, where the side roads are arranged in a left-right sequence.

It is a warning sign and does not by itself establish which road has priority. Drivers must follow the applicable stop signs, give-way signs, traffic signals, road markings and other traffic-control instructions at each junction.

What Is a Staggered Junction?

A staggered junction occurs when two side roads connect to a through road at separate but closely spaced locations rather than meeting the through road at the same point.

The two junctions are therefore offset from one another. Depending on the direction of travel, a driver may encounter one side road followed shortly afterwards by another side road on the opposite side.

Under the South African Road Traffic Signs Manual, closely situated side-road junctions are considered staggered when the distance between them is equal to or less than 3.0 times the operating or design speed in metres. When the junctions are farther apart than this, separate side-road junction warning signs such as W107 or W108 should be considered.

W110 Staggered Junctions (L-R) Ahead

The W110 sign represents a specific staggered-junction arrangement in which the side-road sequence is shown as left-right.

The corresponding mirrored arrangement is W109 Staggered Junctions (R-L) Ahead. The correct sign should be selected according to the actual sequence of the side roads on the approach.

Where Are W110 Signs Used?

W110 signs may be used on approaches to closely situated side-road junctions where joining or leaving traffic, or restricted sight distance, may make the junction arrangement dangerous or potentially dangerous.

Potential applications include:

• Urban roads
• Suburban roads
• Rural roads
• Residential areas
• Commercial developments
• Industrial areas
• Residential estates
• Roads with closely spaced side roads
• Locations with restricted visibility
• Road approaches where the staggered layout may not be immediately obvious

Why Are Staggered Junction Warning Signs Important?

Closely spaced junctions can result in several vehicle movements occurring within a short section of road. Vehicles may enter or leave the through road from different directions at the two junctions.

Advance warning helps drivers recognise that they are approaching a staggered junction arrangement rather than a single side-road intersection.

This can be particularly useful where road alignment, vegetation, buildings, terrain or other conditions restrict the driver's view of one or both junctions.

How Should Drivers Respond to a W110 Sign?

Drivers approaching a W110 sign should remain alert for both junctions and adjust their driving to the conditions ahead.

Drivers should:

• Reduce speed where appropriate.
• Watch for vehicles entering from either side road.
• Look carefully for both junctions.
• Observe stop and give-way signs.
• Follow traffic signals and road markings.
• Be prepared to stop where required.
• Watch for pedestrians, cyclists and other road users.

W110 Sign Placement

The W110 sign should be positioned in advance of the first junction of the staggered arrangement so approaching drivers have enough time to recognise the warning and prepare for the road layout.

Placement should take into account the operating speed, sight distance, road alignment, visibility and other conditions affecting the approach to the junctions.

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

W110 Sign Design and Colours

The permanent W110 warning sign uses a triangular warning-sign design with a red retroreflective triangle, black semi-matt symbol and white retroreflective background.

A temporary version, TW110, is available for temporary staggered-junction arrangements associated with roadworks. The temporary version uses a red retroreflective triangle, black semi-matt symbol and yellow retroreflective background.

W110 and W109 Staggered Junction Signs

W109 and W110 both provide warnings about staggered junctions, but the symbols represent opposite arrangements.

• W109: Staggered Junctions (R-L) Ahead.
• W110: Staggered Junctions (L-R) Ahead.

The correct version should match the actual sequence of the side-road junctions ahead.

W110 Compared with W107 and W108

W107 and W108 are used for individual side-road junction warnings, while W109 and W110 are used where side-road junctions are sufficiently close together to form a staggered junction arrangement.

Where the separation between the junctions exceeds the applicable staggered-junction distance, separate side-road junction warnings should be considered instead.

W110 Signs in South Africa

The W110 Staggered Junctions (L-R) Ahead 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.

Who May Need W110 Signs?

W110 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
• Industrial facilities
• Commercial developments
• Private road operators
• Property and facility managers

Benefits of Clear Staggered Junction Warning Signs

• Provides advance information about an unusual road layout.
• Alerts drivers to traffic movements from both sides of the road.
• Gives drivers time to prepare for the junction arrangement.
• Can be useful where sight distance is restricted.
• Supports organised traffic management at complex road layouts.

Frequently Asked Questions About W110 Road Signs

What does W110 mean?

W110 means Staggered Junctions (L-R) Ahead. It warns drivers that closely situated side-road junctions are approaching in a left-right staggered arrangement.

Is W110 a warning sign?

Yes. W110 provides advance warning of staggered junctions ahead.

Does W110 mean that I must stop?

No. W110 is a warning sign and does not by itself require drivers to stop. Drivers must follow the traffic-control instructions applicable at the junctions.

What is the difference between W109 and W110?

W109 represents the R-L staggered junction arrangement, while W110 represents the L-R arrangement.

What makes two side roads a staggered junction?

The South African Road Traffic Signs Manual considers closely situated side-road junctions to be staggered when the distance between them is equal to or less than 3.0 times the operating or design speed in metres.

When should W107 or W108 be used instead?

Where the side-road junctions are farther apart than the applicable staggered-junction distance, separate Side-Road Junction warning signs such as W107 or W108 should be considered.

Is there a temporary W110 sign?

Yes. TW110 is the temporary version and may be used where temporary staggered junctions are created as a result of roadworks.
