Coloured Road Studs

There are many varieties of road studs, most of which can be coloured to denote different uses. These colours are formalised in the Highway Code, and relate to the area of the road they are placed in. Many of us have internalised these colours even if we haven’t formally learned them – helping us to identify the layout of the road ahead with a quick glance.

 

The most common coloured road studs are:

  • White studs

White studs are used to denote lanes on motorways, as well as the dashed centre lines on single carriageways. They are perhaps the most common and visible form of road stud.

 

  • Red studs

Red studs mark any line which should not be crossed by a vehicle. In practice, this is usually the left edge of the carriageway, as cars in the UK drive on the left-hand side of the road.

 

  • Amber studs

Amber studs mark out an area which should not be crossed on the right-hand side of the road. In practice, this is usually the central reservation on a dual carriageway or motorway.

 

  • Green studs

Green studs indicate a point at which a vehicle can exit the main carriageway. This includes slip roads (where a junction joins or leaves the motorway) as well as bus stops and lay-bys.

 

  • Green/yellow studs

Studs which include both green and yellow colouring indicate temporary changes to the layout of the road. These are often due to roadworks, and most commonly highlight the creation of new lanes.

 

Hi-Way Services can provide a full range of road studs – including reflective, non-reflective and solar-powered studs – in various colours, depending on how they will be used.
