Single-Carriageway Freeway Begins – R402 Road Sign

The Single-Carriageway Freeway Begins road sign, identified as R402, is a South African regulatory sign used to indicate that a single-carriageway freeway begins ahead. The sign also indicates that the specific legislation and traffic regulations applicable to freeways apply to the section of public road beyond the sign.

For road-signing purposes, a single-carriageway freeway is classified as a Class A2 road, while a dual-carriageway freeway is classified as a Class A1 road.

What Does the R402 Road Sign Mean?

R402 means Single-Carriageway Freeway Begins.

The sign tells drivers that they are entering a single-carriageway freeway and that the applicable freeway regulations apply from the designated point.

The South African Road Traffic Signs Manual states that it is the display of R401 or R402 that designates a roadway as a freeway in terms of the relevant legislation.

What Is a Single-Carriageway Freeway?

A single-carriageway freeway is a freeway classified as a Class A2 road. Unlike a dual-carriageway freeway, the roadway operates as a single carriageway rather than having separate carriageways for opposing directions of traffic.

Despite the different roadway configuration, the road is still designated as a freeway when the appropriate freeway sign is displayed and the applicable freeway requirements come into effect.

Where Is R402 Used?

R402 is used at the beginning of a single-carriageway freeway. According to SARTSM, it should be displayed on the left-hand side of on-ramps leading to a single-carriageway freeway.

It can also be used where a single-carriageway freeway begins as a continuation of a lower-class roadway or where a Class A1 dual-carriageway freeway changes to a Class A2 single-carriageway freeway.

R402 at Freeway Entrances

Drivers entering a single-carriageway freeway need to know when the freeway designation begins. R402 provides this indication at the appropriate point on the entrance or transition to the Class A2 freeway.

The sign should be positioned in accordance with the applicable South African road-signing requirements so that it is clearly visible to approaching drivers.

R402 and Freeway Regulations

Once R402 designates the beginning of a single-carriageway freeway, specific freeway regulations apply to the section of road beyond the sign.

These regulations can include requirements and restrictions relating to the types of road users permitted on freeways, stopping, reversing, U-turns, pedestrians, animals and other freeway activities.

The complete legal requirements are contained in the applicable road-traffic legislation. SARTSM provides guidance on the signing and summarises relevant freeway provisions, but the legislation should be consulted for the full requirements.

R402 and U-Turns

One of the freeway restrictions specifically noted for a Class A2 single-carriageway freeway is that no person shall cause a vehicle to execute a U-turn on the freeway.

This is one of the specific requirements associated with the Class A2 freeway designation. Other freeway requirements may also apply depending on the circumstances and applicable legislation.

R402 and Distance Supplementary Plates

In appropriate situations, R402 may be displayed together with an IN11.3 supplementary distance plate.

This arrangement can be used in advance of the beginning of a Class A2 freeway to indicate the distance to the point where the single-carriageway freeway starts. SARTSM provides for this application where the freeway begins beyond the immediate position of the sign.

R402 Sign Colours

The permanent R402 sign uses the following colour arrangement:

• Border: Red retroreflective
• Symbol: White retroreflective
• Background: Blue retroreflective

For temporary applications, the corresponding TR402 sign uses a red retroreflective border, black semi-matt symbol and yellow retroreflective background.

R402 Sign Size

R402 should be sized according to the applicable requirements in SARTSM Volume 1 and Volume 4. The correct size depends on the road environment and the approved sign application.

There is therefore no single universal physical size that should be used for every R402 installation.

R402 During Roadworks

Temporary freeway arrangements may require changes to the normal road configuration.

SARTSM provides TR402 for temporary situations. For example, where one carriageway of a Class A1 dual-carriageway freeway is closed and the remaining carriageway operates with two-way traffic, TR402 can be used to indicate the temporary Class A2 freeway status.

R402 vs R401

R402 should not be confused with R401. The two signs identify different types of freeway:

• R401: Dual-Carriageway Freeway Begins
• R402: Single-Carriageway Freeway Begins

R401 identifies a Class A1 dual-carriageway freeway, while R402 identifies a Class A2 single-carriageway freeway.

R402 vs R402-600

R402 is the sign used to indicate that a single-carriageway freeway begins. R402-600 is a separate de-restriction sign used to indicate that the single-carriageway freeway ends and the relevant freeway restrictions are removed.

This distinction is important when selecting signs for freeway entrances and exits.

Who May Need R402 Freeway Signs?

R402 signage may be relevant to organisations involved in road and transport infrastructure, including:

• Road authorities
• Municipalities
• Provincial transport authorities
• Road construction contractors
• Freeway construction projects
• Traffic-management contractors
• Road maintenance contractors
• Freeway upgrade projects
• Transport infrastructure projects

Benefits of Correct R402 Signage

• Clearly identifies the beginning of a single-carriageway freeway.
• Informs drivers that freeway-specific regulations apply.
• Helps identify the transition to a Class A2 freeway.
• Supports consistent freeway traffic management.
• Provides a clear regulatory indication at freeway entrances and road transitions.
