Concealed Driveway Ahead – W216 Road Sign

The W216 Concealed Driveway road sign is a warning sign used to alert drivers that one or more concealed driveways are located on the right side of the roadway ahead.

The warning is used where restricted sight distance means that vehicles entering the roadway from these driveways may constitute a hazard. It gives approaching drivers advance information that they should take extra caution when travelling through the affected section.

What Does the W216 Road Sign Mean?

W216 warns drivers about concealed driveways on the right.

The sign is intended for situations where the driveway or access point cannot be seen clearly from a sufficient distance because of restricted visibility. Vehicles may enter the roadway from the concealed access, creating a potential hazard for approaching traffic.

W216 is a warning sign. It does not itself require drivers to stop or impose a specific speed limit. Drivers should follow the applicable speed limit and respond to the actual road conditions.

What Is a Concealed Driveway?

A concealed driveway is a private or property access point that is difficult for approaching drivers to see in advance.

The restricted visibility may result from the horizontal or vertical curvature of the roadway, encroaching vegetation or a combination of these conditions.

Because a driver may have limited time to see a vehicle entering the roadway, the W216 warning provides advance information about the hidden access points.

Where Are W216 Signs Used?

W216 signs may be displayed in advance of a section of roadway where one or more concealed driveways exist on the right and where restricted sight distance may make vehicles entering the road a hazard.

Potential applications include:

• Rural roads
• Suburban roads
• Residential areas
• Roads passing properties with multiple driveways
• Roads with horizontal curves
• Roads with vertical curves or crests
• Locations affected by roadside vegetation
• Commercial property accesses
• Industrial property accesses
• Private developments with restricted driveway visibility

Why Is a Concealed Driveway Warning Sign Important?

A driveway that cannot be seen clearly may allow a vehicle to enter the roadway with limited advance visibility for approaching traffic.

The W216 warning helps draw attention to the possibility of vehicles entering the road from a concealed access point. This gives approaching drivers an opportunity to become more alert and adjust their driving to the conditions.

What Causes a Driveway to Be Concealed?

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

For example, a driveway near a sharp bend may be hidden from approaching drivers. A driveway near the crest of a vertical curve may also have restricted visibility.

Where the specific cause of concealment needs to be represented more accurately, the main direction-of-movement arrow used in the W216 symbol can be modified to suit the site conditions.

How Should Drivers Respond to a W216 Sign?

Drivers approaching a W216 sign should be alert for vehicles entering the roadway from concealed driveways on the right.

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 any applicable speed-limit and traffic-control signs.

W216 Sign Placement

The W216 sign should be positioned in advance of the section of roadway where the concealed driveway hazard may occur.

The South African Road Traffic Signs Manual states that the sign should be located according to the operating speed of the road, using the distances provided in Table 3.1 or Figure 3.1.

Where the particular roadway experience indicates that additional information would be useful, a supplementary advisory speed or distance plate may be placed below the W216 sign on the same support.

The sign should have clear visibility for approaching traffic and should not be obstructed by vegetation, buildings, advertising boards or other roadside objects.

W216 Sign Design and Colours

The permanent W216 warning sign uses the standard South African warning-sign colour arrangement:

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

The sign symbol indicates the direction of travel and the concealed driveway arrangement. The W216 configuration represents a concealed driveway on the right side of the roadway.

Temporary W216 Sign

A temporary version, TW216, is also specified.

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

TW216 may be used under the same circumstances as the permanent concealed-driveway warning sign when a temporary roadworks detour creates reduced visibility of access points to the roadway.

W216, W217 and W218

The concealed-driveway warning signs are divided according to the side of the road on which the concealed driveway occurs:

• 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 access points.

W216 and Road Curvature

The W216 symbol normally uses a winding-road type indication to represent the general condition. The South African Road Traffic Signs Manual allows the main direction-of-movement arrow to be modified when a more specific indication of the road condition is required.

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

W216 and Sharp Curve Warning Signs

A concealed driveway warning may sometimes be used together with other appropriate warning signs.

South African road-sign guidance specifically gives an example of a sharp bend where the sight distance to property accesses is limited. In such situations, the design characteristics of W216, W217 or W218 may be used together with an appropriate Sharp Curve warning sign where required by the actual road conditions.

W216 Compared with W217 and W218

The difference between the concealed-driveway signs is the side of the road on which the concealed access occurs.

W216 is used for concealed driveways on the right, W217 for concealed driveways on the left, and W218 where concealed driveways occur on both sides of the roadway.

W216 Sign Visibility and Materials

Outdoor W216 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.

W216 Signs in South Africa

The W216 Concealed Driveway sign forms part of the South African road traffic warning-sign system.

Where W216 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 concealed-driveway 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.

• Municipalities
• Road authorities
• Road construction contractors
• Traffic-management contractors
• Property developers
• Residential estates
