Additional Info

The Keep Left road sign is a regulatory traffic sign used to instruct drivers to pass to the left-hand side of an obstruction in the roadway. It is commonly installed at traffic islands, median islands, road obstructions and other locations where vehicles need to follow a specific direction to continue safely.

The sign provides a clear instruction to drivers approaching the obstruction and helps guide traffic around the correct side of the roadway. Keep Left signs are an important part of traffic management on public roads and can also be used in suitable controlled or private road environments.

What Does the Keep Left Sign Mean?

A Keep Left sign tells drivers that they must pass to the left of the obstruction where the sign is positioned. Drivers should follow the direction indicated by the sign and remain aware of other vehicles, pedestrians, road markings and surrounding traffic conditions.

The sign is different from a general warning sign because it provides a specific traffic instruction rather than simply warning drivers about a potential hazard.

Where Are Keep Left Signs Used?

Keep Left road signs are commonly used at locations where an obstruction or traffic-control feature requires vehicles to move to the left. Applications can include:

  • Traffic islands
  • Median islands
  • Road islands
  • Traffic-calming installations
  • Road obstructions
  • Approaches to divided road sections
  • Construction and temporary traffic-management areas
  • Roadworks and maintenance areas
  • Entrance and exit arrangements
  • Private roads and controlled traffic areas

Keep Left Signs at Traffic Islands

Traffic islands are one of the most common locations for Keep Left signs. An island placed in the centre or near the approach to a roadway can require vehicles to move around a specific side of the obstruction.

The Keep Left sign provides a simple visual instruction so approaching drivers understand which side they should use when passing the island.

Keep Left Signs at Road Obstructions

Road obstructions can include permanent structures, traffic islands, temporary roadworks or other features that affect the normal path of vehicles. A Keep Left sign can be used where traffic needs to move around the obstruction on its left-hand side.

Temporary traffic-management arrangements may require additional signs, cones, barriers, road markings or other traffic-control measures depending on the work being carried out.

Keep Left vs Keep Right Road Signs

Keep Left and Keep Right signs provide different traffic instructions. A Keep Left sign directs traffic to pass to the left of the relevant obstruction, while a Keep Right sign directs traffic to pass to the right.

The correct sign must be selected according to the road layout and the direction in which traffic is required to travel.

Why Are Keep Left Road Signs Important?

Clear directional traffic signs help drivers understand how they should navigate changes in the roadway. At an obstruction or traffic island, providing a clear instruction can help reduce confusion and support an orderly movement of vehicles.

The sign should be installed in a position where approaching drivers have sufficient opportunity to see and respond to the instruction.

Keep Left Signs and Road Safety

Keep Left signs form part of a wider road traffic management system. They should be used together with appropriate road markings, traffic islands, barriers and other traffic-control measures where required.

Drivers should always consider traffic conditions, pedestrians, cyclists, roadworks and other hazards while following the instruction provided by the sign.

Where Should a Keep Left Sign Be Installed?

A Keep Left sign should be positioned so that approaching road users can clearly see the instruction before reaching the obstruction. The exact mounting position depends on the road layout, visibility requirements and applicable road-sign specifications.

For public-road installations, the responsible road authority should determine the appropriate sign location, size, mounting method and other installation requirements.

Permanent and Temporary Keep Left Signs

Keep Left signs may be used for permanent road layouts as well as temporary traffic-management arrangements, depending on the application. Temporary roadworks may require additional traffic-control signs and devices to guide vehicles safely through the affected area.

Keep Left Signs in South Africa

The Keep Left sign forms part of South Africa's road traffic sign system and is used to communicate a specific direction of travel around an obstruction. Public-road signage should follow the applicable South African road traffic requirements and road-sign specifications.

For private roads, industrial properties, shopping centres and other controlled areas, the appropriate traffic signage should be selected according to the road layout, traffic-management plan and applicable requirements.
