Speed Limit of 40 km/h – R201-40 Road Sign

The R201-40 Speed Limit Road Sign indicates that vehicles must not travel faster than 40 km/h beyond the point where the sign is displayed. It is a regulatory road sign used to communicate a maximum permitted speed on a road or controlled traffic area.

A 40 km/h speed limit may be appropriate in areas where vehicle speeds need to be controlled because of pedestrian activity, traffic-calming measures, road layout, limited visibility or other local conditions. The appropriate speed limit should take the surrounding road environment and applicable traffic-management requirements into account.

What Does the R201-40 Sign Mean?

The R201-40 sign means that the maximum permitted vehicle speed is 40 kilometres per hour. Drivers must not exceed 40 km/h beyond the sign while the restriction applies.

R201 is a regulatory speed-limit sign. The South African Road Traffic Signs Manual states that it imposes a mandatory requirement on drivers of vehicles on a public road not to exceed the speed indicated on the sign. Speed limits should preferably be displayed in increments of 10 km/h, making R201-40 the appropriate designation for a 40 km/h limit.

Where Can a 40 km/h Speed Limit Sign Be Used?

A 40 km/h speed limit can be considered for locations where vehicle speeds need to be controlled. Depending on the site and applicable requirements, possible applications include:

• Residential areas and developments
• Traffic-calming zones
• Parking areas and internal access roads
• Business parks and commercial properties
• Industrial properties and warehouses
• Areas with regular pedestrian movement
• School and community environments where appropriate
• Private roads and internal property routes
• Shopping centres and large property developments
• Construction and temporary traffic-management areas

For public roads, the speed limit should be established and implemented according to the requirements of the relevant road authority. On private property, property owners, site managers or responsible authorities should consider the site's traffic-management requirements when selecting and positioning speed-limit signage.

R201-40 Road Sign Design

The R201-40 follows the standard design of the South African R201 speed-limit series. Permanent R201 signs use a red retroreflective border, a white retroreflective background and black semi-matt numerals and legend.

Retroreflective materials can help the sign remain visible when illuminated by vehicle headlights. Sign size and material can be selected according to the road environment, mounting position and applicable specifications.

Placement of a 40 km/h Speed Limit Sign

The R201-40 sign should be positioned at the point where the 40 km/h speed limit begins. SARTSM specifies that R201 signs should normally be displayed on the left-hand side of the roadway. A second sign is recommended on the right-hand side of one-way roadways, including dual-carriageway carriageways that have two or more lanes.

Where the speed limit changes, the sign should be positioned clearly so that drivers can identify the new restriction. The exact location and spacing should take the roadway layout, visibility, traffic conditions and applicable requirements into account.

40 km/h Speed Limits in Traffic-Calming Areas

A 40 km/h limit can form part of a wider traffic-calming approach. SARTSM includes 40 km/h as one of the speed-limit options that may be used for traffic-calming zones, depending on the design and requirements of the area.

The speed-limit sign should be considered together with the overall road layout and any other signs, road markings or traffic-calming measures used in the area.

Permanent and Temporary 40 km/h Speed Limit Signs

The R201-40 designation is used for the permanent speed-limit application. Where a 40 km/h restriction is required for temporary traffic control, the appropriate TR201 temporary speed-limit sign may be used in accordance with the applicable traffic-management requirements.

Temporary speed restrictions may be relevant to roadworks, construction areas, temporary traffic arrangements or other situations where vehicle speeds need to be controlled for a limited period.

Why Use a 40 km/h Speed Limit Sign?

A clearly positioned 40 km/h speed-limit sign communicates the maximum permitted vehicle speed to drivers. A controlled speed may be appropriate where pedestrians, workers, vehicles or other road users are operating in an environment that requires additional speed management.

SARTSM states that the speed indicated on an R201 sign should be a realistic safe speed that considers factors such as roadway alignment, surface condition, traffic volumes and roadside obstacles.

R201-40 Speed Limit Sign for Private Property

40 km/h speed-limit signs can also form part of traffic management on suitable private properties. Applications may include shopping centres, business parks, residential estates, factories, warehouses, parking facilities and other controlled-access sites.

For private-property applications, the sign should form part of the site's overall traffic-management approach. Property owners and managers should consider pedestrian movement, vehicle access, visibility, road layout and any requirements from landlords, property managers or relevant authorities.
