Product Description

Combined Curves (Right-Left) Ahead – W210 Road Sign

The W210 Combined Curves (Right-Left) Ahead road sign is a warning sign used to alert drivers that two sharp curves in opposite directions are approaching. The first curve is to the right, followed by a curve to the left.

The sign provides advance warning of a changing road alignment where drivers may need to adjust their speed and direction more than once within a relatively short section of road.

What Does the W210 Road Sign Mean?

W210 means Combined Curves. It warns drivers that a combination of two sharp curves in opposite directions is ahead, with the first curve to the right and the second curve to the left.

W210 is a warning sign and does not itself impose a particular speed limit. Drivers must comply with the applicable speed limit and adjust their speed to the road, traffic, visibility and curve conditions.

What Are Combined Curves?

Combined curves are two sharp curves that occur in opposite directions within a relatively short section of road.

For W210, the road first curves to the right and then changes direction to the left. This type of road layout can require drivers to make repeated steering and speed adjustments.

When Is W210 Used?

The South African Road Traffic Signs Manual states that W210 and W211 are used to warn road users of a combination of two sharp curves in opposite directions.

The signs should be displayed where:

• The speed needs to be reduced by more than one-third of the operating speed of traffic travelling on the preceding straight.
• The straight section between the two curves is less than 120 metres.
• The nature of the reverse curves is not obvious to approaching traffic and therefore presents a hazard.

These conditions help distinguish combined-curve warnings from ordinary curve warning signs.

Where Are W210 Signs Used?

W210 signs may be used on approaches to sections containing two sharp curves in opposite directions where advance warning is required.

Potential applications include:

• Urban roads
• Suburban roads
• Rural roads
• Mountain and hilly roads
• Highways and regional roads
• Residential roads
• Commercial developments
• Industrial areas
• Roads with restricted forward visibility
• Temporary roadworks detours

Why Is a Combined Curves Warning Sign Important?

Two sharp curves in opposite directions can require drivers to change direction twice over a short distance. If the second curve is not immediately obvious after the first, drivers may need additional warning to prepare for the changing road alignment.

W210 provides advance information about the sequence of curves so drivers can approach the section with greater awareness and adjust their driving to the conditions.

How Should Drivers Respond to a W210 Sign?

Drivers approaching a W210 sign should prepare for the two sharp curves ahead and remain alert throughout the combined-curve section.

Drivers should:

• Observe the posted speed limit.
• Adjust speed before entering the first curve where appropriate.
• Maintain control of the vehicle through both curves.
• Follow the lane alignment and road markings.
• Look beyond the first curve for the second change in direction.
• Remain alert to approaching and following vehicles.
• Watch for pedestrians, cyclists and other road users where applicable.

W210 Sign Placement

The W210 sign should be positioned in advance of the beginning of the combined-curve section so approaching drivers have sufficient time to recognise the warning and prepare for the road alignment ahead.

The South African Road Traffic Signs Manual states that the advance distance should depend on the average entering speed for the preceding straight and the safe speed determined for negotiating the curves. The applicable guidance in the manual should be used to establish the appropriate sign position.

Where appropriate, an advisory safe speed may be displayed on a supplementary information plate below the warning sign.

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

W210 Sign Design and Colours

The permanent W210 warning sign follows the standard South African warning-sign colour arrangement:

• Triangle: Red retroreflective
• Symbol: Black semi-matt
• Background: White retroreflective

The symbol shows the combined curve arrangement, with the first curve to the right followed by a curve to the left.

Temporary W210 Sign

A temporary version, TW210, is specified for temporary road layouts.

The temporary sign uses a red retroreflective triangle, black semi-matt symbol and yellow retroreflective background. TW210 may be used under the applicable circumstances where combined curves occur within a temporary roadworks detour.

W210 and W211

W210 and W211 represent opposite combined-curve arrangements:

• W210: Combined Curves, first curve right then left.
• W211: Combined Curves, first curve left then right.

The correct sign should be selected according to the direction of the first curve in the sequence.

W210 Compared with W208 and W209

W210 and W211 should not be confused with W208 and W209.

W208 and W209 warn about a series of reverse curves in a winding section of road, while W210 and W211 are specifically used for a combination of two sharp curves in opposite directions.

The appropriate sign should therefore be selected according to the actual road geometry and the conditions experienced by approaching drivers.

W210 Compared with Sharp Curve and Hairpin Bend Signs

W210 is used for a combination of two sharp curves in opposite directions. Where an individual curve is substantially more severe, the appropriate Sharp Curve or Hairpin Bend warning sign may be required instead.

W204 and W205 cover sharp curves, while W206 and W207 cover hairpin bends. The correct sign depends on the actual geometry and the required speed reduction.

W210 and Advisory Safe Speed

W210 warns about the combined curves but does not itself impose a regulatory speed limit.

Where appropriate, an advisory safe speed may be displayed on a supplementary information plate below the warning sign. This advisory information should not be confused with a legally applicable speed limit.

W210 During Roadworks

The temporary TW210 sign may be used where two sharp curves in opposite directions form part of a temporary roadworks detour.

Temporary warning signage should form part of the wider traffic-management arrangement for the work zone, together with any other warning, regulatory and directional signs required by the temporary road layout.

W210 Sign Visibility and Materials

Outdoor W210 signs should be manufactured using materials suitable for the environmental conditions in which they will be installed.

For public-road applications, the sign's dimensions, design, mounting arrangement, colours and retroreflective characteristics should comply with the applicable South African road traffic sign requirements and the requirements of the responsible road authority.

Retroreflective materials can help improve the visibility of the warning sign when illuminated by vehicle headlights at night.

W210 Signs in South Africa

The W210 Combined Curves sign forms part of the South African road traffic warning-sign system.

Where W210 is used on a public road, its selection, 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.

W210 signage may be relevant to organisations responsible for roads, infrastructure, traffic management and property development, including:

• Municipalities
• Road authorities
• Road construction contractors
• Traffic-management contractors
• Highway and regional-road contractors
• Property developers
• Residential estates
• Industrial facilities
• Commercial developments
• Road maintenance contractors
