Product Description
One-Way Roadway (Right) Road Sign – R4.2
The One-Way Roadway (Right) road sign, officially designated R4.2 in the South African Road Traffic Signs Manual (SARTSM), is a regulatory traffic sign used to indicate that vehicles using the designated roadway must travel in the direction shown by the right-pointing arrow.
The R4.2 sign helps communicate the permitted direction of travel and is particularly useful at one-way roadways, junctions, parking facilities and other traffic areas where drivers need clear information about the direction they are required to follow.
What Does a One-Way Roadway (Right) Sign Mean?
The R4.2 One-Way Roadway sign imposes a mandatory requirement on drivers that, if they intend to use the roadway concerned, they must proceed only in the direction indicated by the arrow.
The right-pointing arrow identifies the direction of permitted travel. Drivers should also follow any road markings, lane arrows, intersection controls and other traffic signs that apply to the particular roadway.
Where Are R4.2 One-Way Roadway Signs Used?
One-way roadway signs can be used in a variety of public and private traffic environments, including:
- One-way streets and roads
- Urban traffic routes
- Road junctions
- Shopping centres
- Parking areas and parking garages
- Business parks
- Residential estates
- Industrial properties
- Warehouse and logistics facilities
- Private access roads
- Large commercial developments
- Temporary traffic routes where an appropriate one-way arrangement has been established
Why Are One-Way Roadway Signs Important?
A one-way traffic arrangement controls the direction in which vehicles use a particular roadway. Clear regulatory signage helps drivers understand the permitted direction and avoid travelling against the designated traffic flow.
This is particularly important at junctions and access points where the physical road layout may not make the one-way arrangement immediately obvious.
The South African Road Traffic Signs Manual states that R4.1, R4.2 and R4.3 impose a mandatory requirement on drivers to proceed only in the direction indicated by the arrow.
R4.2 One-Way Roadway Signs at Junctions
R4.2 signs can be used at junctions with one-way roadways to indicate that vehicles must follow the direction shown by the arrow and that two-way travel is not permitted on the designated roadway.
The sign should be carefully positioned at the potential point where a driver could otherwise enter the roadway in the wrong direction. The sign should make it clear which leg of the junction is affected.
Depending on the junction layout, additional traffic-control signs and road markings may be required to make the permitted movements clear.
One-Way Roadway Signs in Parking Areas
Shopping centres, parking garages and large parking facilities often use one-way routes to organise vehicle movement between entrances, parking bays and exits.
An R4.2 One-Way Roadway (Right) sign can indicate that traffic must proceed to the right along the designated route. Additional directional arrows, parking signs and road markings can be used where the layout requires further guidance.
One-Way Roadway Signs on Private Property
R4.2 signs can also be considered for suitable private roads and internal traffic routes. Applications can include:
- Shopping centres
- Office parks
- Residential estates
- Factories
- Warehouses
- Hotels and resorts
- Hospitals and healthcare facilities
- Private parking facilities
- Commercial developments
For private-property installations, the sign should form part of an appropriate traffic-management arrangement that considers vehicle movement, pedestrian access, entrances, exits and emergency routes.
R4.2 and No Entry R3 Signs
The R4.2 One-Way Roadway sign and the R3 No Entry sign serve different purposes.
R4.2 tells drivers the direction in which they must travel on a one-way roadway. R3 prohibits vehicular entry from the direction where the No Entry sign is displayed.
The South African Road Traffic Signs Manual states that R4.1 and R4.2 should be used at junctions with one-way roadways. It also notes that R3 may be used at such junctions in special situations involving alignment or visibility where additional emphasis is required.
Temporary One-Way Traffic Control
One-way traffic arrangements may also be introduced temporarily during construction, road maintenance, utility work, events or other changes to normal traffic flow.
Where a temporary one-way route is established, the applicable temporary traffic-control signs and road markings should clearly communicate the permitted direction of travel.
For public-road work, temporary traffic arrangements should comply with the requirements of the responsible road or traffic authority.
R4.2 Sign Placement and Visibility
The R4.2 sign should be carefully sited at the potential point of wrong-way entry so that drivers can clearly understand which roadway is affected.
The South African Road Traffic Signs Manual recommends that, in most situations, two one-way roadway signs may be used, with one on each side of the roadway. The signs may also need to be positioned slightly into the one-way roadway or orientated to suit approaching traffic.
The sign should remain clearly visible and should not be unnecessarily obstructed by vegetation, buildings, parked vehicles, advertising structures or other objects.
R4.2 One-Way Roadway Sign Size
South African road-signing specifications provide minimum dimensions for R4.1, R4.2 and R4.3 One-Way Roadway signs. The minimum dimensions are 450 mm in height by 600 mm in length, subject to the applicable sign-size provisions and application.
The appropriate sign size for a particular installation should be selected according to the road environment, traffic conditions and applicable road-signing requirements.
One-Way Roadway Signs in South Africa
The R4.2 One-Way Roadway (Right) sign is part of the South African regulatory traffic-sign system. R4.1, R4.2 and R4.3 communicate the permitted direction of travel through their respective arrows.
For public roads, the applicable sign specification, positioning and installation requirements should be confirmed with the responsible road or traffic authority. Private-property owners and managers should consider the site's traffic-management requirements when introducing one-way traffic routes.
