Hairpin Bend (Left) Ahead – W207 Road Sign

The W207 Hairpin Bend (Left) Ahead road sign is a warning sign used to alert drivers that a very sharp bend is approaching on the left. The bend results in an almost complete change in direction and requires drivers to prepare for a significant change in the road alignment.

W207 is intended specifically for a hairpin bend rather than an ordinary curve. The warning gives approaching drivers advance information so they can recognise the sharp change in direction and adjust their driving before reaching the bend.

What Does the W207 Road Sign Mean?

W207 means Hairpin Bend (Left) Ahead. It warns drivers that a very sharp left-hand bend is approaching.

W207 is a warning sign and does not itself impose a specific speed limit. Drivers must comply with the applicable speed limit and adjust their speed according to the road, traffic, visibility and bend conditions.

What Is a Hairpin Bend?

A hairpin bend is an extremely sharp bend where the road changes direction by almost a complete turn. It can require drivers to make a major change in direction within a relatively short distance.

Hairpin bends are commonly associated with mountainous and hilly roads, but they can also occur on other roads where the road geometry requires a very sharp change in direction.

When Is W207 Used?

The South African Road Traffic Signs Manual identifies W206 and W207 Hairpin Bend signs for sharp bends that result in an almost complete change of direction to the right or left.

These signs should be displayed in advance of an obscured sharp bend that can only be negotiated comfortably by reducing speed by more than half of the operating speed of traffic travelling on the preceding straight section. The appropriate safe speed should be determined for the particular location.

Where Are W207 Signs Used?

W207 signs may be used on approaches to sharp left-hand hairpin bends where advance warning is required.

Potential applications include:

• Mountain roads
• Hilly areas
• Rural roads
• Scenic routes
• Regional roads
• Roads with steep or winding terrain
• Locations with restricted forward visibility
• Curves obscured by terrain or vegetation
• Temporary roadworks detours
• Private roads with significant changes in elevation

Why Is a Hairpin Bend Warning Sign Important?

A hairpin bend represents a major change in road direction and can require drivers to reduce speed considerably before entering the bend.

Where the bend is difficult to see from a distance, drivers may have less time to recognise how sharply the road changes direction. W207 provides advance warning so road users can prepare before reaching the bend.

The warning can be particularly useful where terrain, vegetation, buildings, a crest or the road alignment restricts forward visibility.

How Should Drivers Respond to a W207 Sign?

Drivers approaching a W207 sign should remain alert and prepare for the sharp left-hand hairpin bend ahead.

Drivers should:

• Observe the posted speed limit.
• Reduce speed before reaching the bend where appropriate.
• Maintain proper control of the vehicle.
• Follow the lane alignment and road markings.
• Watch for approaching vehicles.
• Take additional care where visibility is restricted.
• Watch for pedestrians, cyclists and other road users where applicable.

W207 Sign Placement

The W207 sign should be positioned in advance of the beginning of the hairpin bend so approaching drivers have enough time to recognise the warning and prepare for the change in direction.

The South African Road Traffic Signs Manual states that the advance distance depends on the average entering speed on the preceding straight section and the safe speed determined for negotiating the bend. The applicable road-sign guidance should be used to determine the appropriate distance for the particular location.

Where appropriate, an advisory safe speed may be displayed on a supplementary information plate below the W207 sign.

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

W207 Sign Design and Colours

The permanent W207 warning sign follows the standard South African warning-sign colour arrangement:

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

These characteristics are specified for the permanent Hairpin Bend warning signs.

Temporary W207 Sign

A temporary version, TW207, is also specified for temporary road layouts.

The temporary sign uses a red retroreflective triangle, black semi-matt symbol and yellow retroreflective background. TW207 may be used under the applicable circumstances where a hairpin bend forms part of a temporary roadworks detour.

W207 and W206

W206 and W207 warn about hairpin bends in opposite directions:

• W206: Hairpin Bend (Right) Ahead.
• W207: Hairpin Bend (Left) Ahead.

The correct sign should be selected according to the actual direction of the hairpin bend.

W207 Compared with Sharp Curve Signs

W207 is intended for a hairpin bend, which is more severe than the sharp curves covered by W204 and W205.

The SARTSM distinguishes Hairpin Bend signs from Sharp Curve signs according to the severity of the bend and the amount of speed reduction required. W204 and W205 apply where the required reduction is more than one-third of the operating speed on the preceding straight, while W206 and W207 apply where the required reduction is more than half of the operating speed.

W207 Compared with Gentle Curve Signs

W207 should not be used for an ordinary or gentle bend.

W202 and W203 are used for gentle curves, while W204 and W205 are used for sharper curves. W206 and W207 are used for hairpin bends involving an almost complete change of direction.

Selecting the appropriate warning sign helps ensure that the sign accurately represents the road geometry and the conditions approaching drivers will encounter.

W207 and Advisory Safe Speed

An advisory safe speed may be displayed on a supplementary information plate below the W207 warning sign where appropriate.

This advisory information provides additional guidance about a suitable speed for negotiating the particular bend. It should not be confused with a regulatory speed limit.

W207 During Roadworks

The temporary TW207 sign may be used where a hairpin bend forms part of an applicable 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.

W207 Sign Visibility and Materials

Outdoor W207 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.

W207 Signs in South Africa

The W207 Hairpin Bend (Left) Ahead sign forms part of the South African road traffic warning-sign system.

Where W207 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.

Who May Need W207 Signs?

W207 signage may be relevant to organisations responsible for roads, infrastructure and traffic management, including:

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