Side-Road Junction Ahead – W108 Road Sign

The W108 Side-Road Junction Ahead road sign is a warning sign used to alert drivers that a side-road junction is approaching from the right. It provides advance warning where traffic joining or leaving the road from the right, or restricted visibility to the right, may make the junction dangerous or potentially dangerous.

The sign gives approaching road users time to become more alert, assess the road ahead and prepare for vehicles that may enter or leave the roadway at the side-road junction.

What Does the W108 Road Sign Mean?

The W108 sign warns drivers of a side-road junction on the right ahead.

It is a warning sign rather than a stop or give-way instruction. Drivers must still follow any applicable stop signs, give-way signs, traffic signals, road markings and other traffic-control measures at the junction.

W108 Side-Road Junction Sign Explained

Side-road junctions can introduce traffic movements that drivers need to anticipate. Vehicles may join the road from the side road, turn into it or cross the driver's path.

The W108 warning is particularly relevant where the junction arrangement, traffic movements or restricted sight distance to the right could make the intersection difficult to identify or respond to safely.

Where Are W108 Signs Used?

W108 signs may be used on approaches to side-road junctions where advance warning is required and where the side road is located on the right.

Typical applications can include:

• Urban roads
• Suburban roads
• Rural roads
• Residential areas
• Commercial developments
• Industrial areas
• Estate roads
• Roads with limited sight distance
• Approaches where traffic may enter from a side road
• Locations where the junction is not immediately obvious to approaching drivers

When Is a W108 Sign Appropriate?

According to the South African road-sign standards, W107 and W108 are intended for side-road junctions where joining or leaving traffic from the left or right, or restricted sight distance in that direction, may make the junction dangerous or potentially dangerous.

These signs should normally be used on approaches that do not already have advance direction signs. They would not normally be installed where the side-road junction is controlled by traffic signals or where advance direction signs already provide the necessary information, although additional warning may be appropriate at locations with a history of crashes.

How Should Drivers Respond to a W108 Sign?

Drivers approaching a W108 sign should remain alert and prepare for the side-road junction ahead.

Drivers should:

• Adjust their speed where appropriate for the road conditions.
• Watch carefully for vehicles entering from the right.
• Look for vehicles turning into the side road.
• Observe stop, give-way and priority signs.
• Follow traffic signals and road markings.
• Be prepared to stop where required.
• Watch for pedestrians, cyclists and other road users.

W108 Sign Placement

The W108 sign should be installed in advance of the side-road junction so that approaching drivers have sufficient time to recognise the warning and prepare for the road layout.

Its position should take account of the operating speed, visibility, road alignment, available sight distance and other roadside conditions. The sign should be clearly visible and should not be hidden by vegetation, buildings, advertising boards or other obstructions.

W108 Sign Design and Colours

The permanent W108 warning sign uses a triangular design with a red retroreflective border, a black semi-matt symbol and a white retroreflective background.

A temporary version, TW108, is available for temporary side-road junction arrangements created by roadworks. The temporary sign uses a red retroreflective triangle with a black semi-matt symbol on a yellow retroreflective background.

W108 and W107 Side-Road Junction Signs

W108 and W107 are both Side-Road Junction warning signs, but the symbol arrangement identifies the side from which the side road approaches.

• W107: Side-road junction on the left.
• W108: Side-road junction on the right.

Choosing the correct version is important so that the warning symbol accurately represents the road layout ahead.

W108 Signs in South Africa

The W108 Side-Road Junction Ahead sign forms part of the South African road traffic warning-sign system. Public-road signs should be selected, manufactured and installed in accordance with 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.
