What different cats eyes mean

There are market studs, which are usually referred to as multi-coloured studs or even more usually as cats eyes, along certain areas of motorways and optionally on other parts of motorways too.

These are there to help you when driving at night and provide a clear visual clue as to the current road conditions you face (e.g. you are are about to rejoin a motorway for instance).

There are various different colours of these, and if you ask drivers what they mean they might not know, but as a learner driver who wants to know all about driver theory you should be sure to learn what the different colours mean.

Green cats eyes indicate where you rejoin the main carriageway of the motorway. They also indicate exits and entrances from slip roads.

The colour you may see most often are white ones which are simply used to mark the lanes on the motorway.

You will also come across two other colours - amber studs and red ones. The amber studs mark the edge of the central reservation, whilst the red studs mark the left edge of the carriageway next to the hard shoulder.

Do take the time to learn what the different colours mean - it is useful to have the extra information they provide when driving on motorways at night.
