Road studs come in a wide variety, and the majority of them can be colored to indicate a variety of applications. The Highway Code has formalized these colors, which are related to the section of the road they are put on. Even if we didn't study these colors formally, many of us have internalized them, which makes it easier for us to quickly recognize the layout of the road ahead. The most widely used colors for road studs are:

- White studs: On motorways, lanes are indicated by white studs, and single-carriageway center lines are dashed. They are possibly the most prevalent and noticeable kind of road stud.

- Red studs: Any line that a vehicle should not cross is marked with red studs. Since cars in the UK drive on the left side of the road, in reality, this is typically the left edge of the carriageway.

- Amber studs: On the right side of the road, amber studs designate a zone that should not be crossed. In reality, this is usually the central reservation on a dual carriageway or motorway.

- Green studs: A point where a vehicle can off the main carriageway is marked with green studs. This comprises bus stations, lay-bys, and slip roads (where a junction enters or exits the motorway).

- Green/yellow studs: Studs with both green and yellow coloring denote temporary alterations to the road's layout. These are frequently the result of road construction and typically highlight the creation of new lanes.

Great app, just did 59/60 with first try on my theory exam. Exactly what you need to prepare! Would be great to have hazard perception training too.
