R102 Vehicles Exceeding Mass Only Road Sign

The R102 Vehicles Exceeding Mass Only road sign is a South African command sign used to direct certain heavy vehicles onto the road or portion of road indicated by the sign. The mass shown on the sign relates to the vehicle's Gross Vehicle Mass (GVM) or Gross Combination Mass (GCM).

The R102 sign is used on public roads where vehicles exceeding a specified mass are required to follow a particular route, lane or section of road. The sign helps regulate the movement of heavy vehicles and can be used to direct them towards designated areas such as heavy-vehicle routes, inspection areas, weigh stations or other controlled locations.

What Does the R102 Road Sign Mean?

The R102 means that vehicles with a GVM or GCM exceeding the mass displayed on the sign must use the road or part of the road indicated by the sign. Vehicles below the specified mass are not required to use the indicated section under the R102 command.

For example, an R102 sign displaying 10t applies to vehicles exceeding the specified 10-tonne mass threshold. The exact mass shown on the sign determines which vehicles are required to follow the command.

What Are GVM and GCM?

Gross Vehicle Mass (GVM) refers to the permitted mass of a vehicle, while Gross Combination Mass (GCM) relates to a combination of vehicles. The R102 uses the applicable mass threshold shown in tonnes to identify the vehicles to which the command applies.

Where Is the R102 Sign Used?

The South African road-sign manual states that the R102 may be used on any public road. It is intended for situations where certain heavy vehicles need to be directed to a particular road or portion of road.

Applications can include:

• Heavy-vehicle routes
• Weigh stations
• Vehicle inspection areas
• Heavy-vehicle control points
• Designated heavy-vehicle lanes
• Approaches to controlled road sections
• Industrial and freight routes
• Roads requiring specific heavy-vehicle routing

R102 Sign for Heavy Vehicles

The R102 is particularly relevant to roads where heavy vehicles need to be directed into a designated lane or road section. The South African Road Traffic Signs Manual also provides for its use in directing heavy vehicles towards exclusive heavy-vehicle compulsory stop areas, weigh stations and inspection areas.

R102 Compared With R124

The R102 and R124 signs both relate to vehicle mass, but they are not interchangeable. The R102 applies to vehicles exceeding a specified mass, while R124 is used for goods vehicles exceeding a specified mass. The South African road-sign guidance identifies R102, R123 and R124 as different command signs for different vehicle categories and mass requirements.

R102 Permanent and Temporary Signs

The permanent R102 is the standard command sign for vehicles exceeding the specified mass. The South African Road Traffic Signs Manual also provides for a temporary version, designated TR102, for applicable temporary traffic-management situations.

R102 Road Sign Design

The permanent R102 is a circular regulatory sign displaying the applicable mass in tonnes. The South African Road Traffic Signs Manual specifies the design, colours, retroreflective properties and sizing requirements for the sign.

When specifying an R102 sign, the required mass value should be clearly identified, such as an R102-10 for a 10-tonne application, where appropriate. Sign size and installation should follow the applicable road-sign requirements.

Where Should an R102 Sign Be Installed?

The correct position of an R102 sign depends on the road layout and the traffic-control purpose. The South African Road Traffic Signs Manual states that the sign should generally be displayed on the left-hand side of the roadway. On dual carriageway roads, overhead mounting may be used to indicate the lane into which vehicles exceeding the specified mass must move.

R102 Road Signs in South Africa

The R102 forms part of South Africa's road traffic sign system and is used to communicate mandatory requirements to specified classes of vehicles. The South African Department of Transport publishes road traffic sign guidance covering command and regulatory signs, including the R102 Vehicles Exceeding Mass Only sign.

For public-road installations, the applicable road authority should be consulted regarding the location, mass threshold, sign size, mounting and other installation requirements.
