Concealed Driveway Ahead – W217 Road Sign

The W217 Concealed Driveway road sign is a warning sign used to alert drivers that one or more concealed driveways are located on the left side of the roadway ahead.

The warning is intended for locations where restricted sight distance can make it difficult for approaching drivers to see vehicles entering the road from the driveway. It provides advance information so road users can remain alert and adjust their driving to the conditions ahead.

What Does the W217 Road Sign Mean?

W217 warns drivers about concealed driveways on the left.

The sign indicates that vehicles may enter the roadway from a driveway that is not clearly visible from a sufficient distance. Drivers should therefore take additional care when approaching and travelling through the affected section.

W217 is a warning sign. It does not itself require drivers to stop or impose a specific speed limit. Drivers must continue to follow the applicable speed limit, road markings and other traffic-control instructions.

What Is a Concealed Driveway?

A concealed driveway is a property access point that is difficult for approaching drivers to see because of restricted sight distance.

According to the South African Road Traffic Signs Manual, the concealment will normally result from a combination of horizontal or vertical curvature of the road and/or encroaching vegetation.

A driveway near a bend, crest, embankment or thick vegetation may therefore be difficult to see until a driver is relatively close to it.

Where Are W217 Signs Used?

W217 signs may be displayed in advance of a section of roadway where one or more concealed driveways exist on the left and where vehicles entering the roadway may create a hazard because of restricted visibility.

Potential applications include:

• Rural roads
• Suburban roads
• Residential areas
• Roads with multiple property entrances
• Roads with horizontal curves
• Roads with vertical curves or crests
• Locations affected by roadside vegetation
• Commercial property accesses
• Industrial property accesses
• Residential estates and private developments

Why Is a Concealed Driveway Warning Sign Important?

A concealed driveway can reduce the amount of time available for an approaching driver to see a vehicle entering or leaving a property.

W217 provides advance warning that concealed access points are present on the left side of the roadway. This can help drivers become more aware of possible traffic entering the road and adjust their driving to the visibility and road conditions.

What Can Cause a Driveway to Be Concealed?

Several road and roadside conditions can restrict visibility to a driveway.

These may include:

• Horizontal bends in the road
• Vertical curves or crests
• Dense or encroaching vegetation
• Buildings or walls close to the roadway
• Embankments and changes in ground level
• Other roadside features that obstruct the driver's view

The SARTSM specifically identifies horizontal or vertical curvature and/or encroaching vegetation as normal reasons for the concealment.

How Should Drivers Respond to a W217 Sign?

Drivers approaching a W217 sign should remain alert for vehicles entering the roadway from concealed driveways on the left.

Drivers should:

• Adjust their speed to the road and visibility conditions.
• Watch carefully for vehicles emerging from driveways.
• Be prepared for vehicles entering or turning onto the roadway.
• Maintain proper control of the vehicle.
• Keep a suitable following distance.
• Watch for pedestrians and cyclists using property accesses.
• Follow all applicable speed-limit and traffic-control signs.

W217 Sign Placement

The W217 sign should be positioned in advance of the section where the concealed-driveway hazard may occur.

The South African Road Traffic Signs Manual states that concealed-driveway warning signs should be located in advance of the relevant section according to the operating speed of the road, using the applicable warning-sign location guidance.

Where appropriate, a supplementary advisory-speed or distance plate may be placed below the warning sign on the same support.

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

W217 Sign Design and Colours

The permanent W217 warning sign follows the standard South African warning-sign colour arrangement:

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

The W217 symbol represents the concealed-driveway arrangement on the left side of the road.

Temporary W217 Sign

A temporary version, TW217, is also specified for temporary traffic arrangements.

The temporary version uses a red retroreflective triangle, black semi-matt symbol and yellow retroreflective background.

TW217 may be used under the applicable circumstances where temporary roadworks or a temporary diversion results in reduced visibility of access points to the roadway.

W217, W216 and W218

The concealed-driveway warning signs are differentiated according to the side or sides of the roadway where the concealed access points occur:

• W216: Concealed Driveway on the right.
• W217: Concealed Driveway on the left.
• W218: Concealed Driveways on both sides.

The correct sign should be selected according to the actual location of the concealed driveways.

W217 and Road Curvature

The concealed-driveway warning symbol normally uses a winding-road type indication. The South African Road Traffic Signs Manual allows the main direction-of-movement arrow in the symbol to be modified where a different road condition more accurately represents the cause of the concealed access.

For example, where concealment is caused by a crest on an otherwise straight road, a straight direction-of-movement arrow may be used instead.

W217 and Other Warning Signs

At some locations, the concealed driveway may occur in combination with another road hazard, such as a sharp bend.

Where restricted sight distance and road curvature create multiple hazards, the appropriate combination of warning signs may be considered according to the actual road conditions and applicable road-sign requirements.

W217 Compared with W216

W216 and W217 have the same general purpose but represent opposite sides of the roadway.

• W216: Concealed driveway on the right.
• W217: Concealed driveway on the left.

Choosing the correct version ensures that the warning symbol corresponds with the actual position of the concealed access.

W217 Compared with W218

W218 is used where concealed driveways occur on both sides of the roadway.

W217 should therefore be used where the concealed driveway hazard is specifically on the left side.

W217 Sign Visibility and Materials

Outdoor W217 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.

W217 Signs in South Africa

The W217 Concealed Driveway sign forms part of the South African road traffic warning-sign system.

Where W217 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.

W217 signage may be relevant to organisations and property managers responsible for roads and vehicle access, including:

• Municipalities
• Road authorities
• Road construction contractors
• Traffic-management contractors
• Property developers
• Residential estates
• Commercial properties
• Industrial facilities
• Road maintenance contractors
• Private road operators
