Staggered side-road junctions ahead
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.
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.
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.
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.
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:
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.
Drivers approaching a W110 sign should remain alert for both junctions and adjust their driving to the conditions ahead.
Drivers should:
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.
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.
W109 and W110 both provide warnings about staggered junctions, but the symbols represent opposite arrangements.
The correct version should match the actual sequence of the side-road junctions ahead.
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.
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.
W110 signage may be relevant to organisations involved in road construction, property development and traffic management, including:
W110 means Staggered Junctions (L-R) Ahead. It warns drivers that closely situated side-road junctions are approaching in a left-right staggered arrangement.
Yes. W110 provides advance warning of staggered junctions ahead.
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.
W109 represents the R-L staggered junction arrangement, while W110 represents the L-R arrangement.
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.
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.
Yes. TW110 is the temporary version and may be used where temporary staggered junctions are created as a result of roadworks.

Staggered side-road junctions ahead 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 Staggered side-road junctions ahead 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. Staggered side-road junctions ahead 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.
Safety signs are an essential part of any workplace or public space. They are used to warn people of potential hazards, provide guidance on safe behavior, and ensure compliance with safety regulations. One type of safety sign is the Staggered side-road junctions ahead sign, which is designed to alert people to potential dangers in a particular area. Staggered side-road junctions ahead signs come in a variety of styles and formats, including danger signs, warning signs, and caution signs.

These signs indicate the location of fire exits, fire extinguishers, and other fire safety equipment. In addition to these types of safety signs, there are also specialized signs available for specific industries or hazards. For example, construction sites may use signs to indicate the location of underground utilities or to warn of falling debris. 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.
