Raised pavement markers, popularly known as 'cat's eyes' in Ireland, are critical safety devices used on national roads and motorways. They utilize retroreflective technology to bounce headlight beams back to drivers, outlining road lanes and edges. Mastering their colour-coding system is highly relevant for passing the Irish Driver Theory Test (DTT) and ensuring safe driving at night.
A retroreflective safety device installed in or on the road surface to outline traffic lanes and road edges, particularly visible at night or in wet conditions.
Red is Left (danger), Amber is Right (median/barrier), White is Middle (lanes), Green is Slip (exit lanes).

See how Raised Pavement Marker appears in realistic driving situations relevant to Ireland. These examples explain correct behaviour, safety implications, and how Raised Pavement Marker connects to Irish driving theory exam questions.
Driving along an unlit, twisty national road in County Kerry at night during heavy rain, making the painted white lines difficult to see.
Track the red markers on your far left and the white markers on your right to stay safely positioned in your lane.
The red markers delineate the left edge of the road, while the white markers outline the lane boundary, ensuring you do not drift into the grass ditch or oncoming traffic when paint is invisible.
Approaching a slip road on the M50 motorway at night and wanting to identify where the exit lane begins.
Look for a line of green markers crossing the lane divider on your left, indicating the slip road entrance.
Green markers are specifically used to denote the boundaries of slip roads, deceleration lanes, and lay-bys that drivers are permitted to cross.
Driving in the fast lane (lane 2) of a dual carriageway and noticing amber markers on your immediate right.
Maintain a safe position to the left of the amber markers, using them to gauge your distance from the central barrier.
Amber markers are always placed on the right-hand edge of the road next to the central reservation or median barrier.

A raised pavement marker is a small, highly reflective road safety device embedded in or attached directly to the asphalt. Invented in the 1930s as the iconic 'cat's eye', these studs are designed to bounce light from vehicle headlights back towards the driver. This retroreflective property allows drivers to see the path of the road far beyond the reach of standard headlights, especially on unlit national roads or during heavy rain when painted lines disappear under a sheet of water.
In Ireland, raised pavement markers follow a strict colour system to indicate your position on the road relative to lanes, shoulders, and hazards:
Beyond providing visual guidance, raised pavement markers act as physical warning systems. When a vehicle drifts out of its lane and rolls over these markers, the tyres produce a distinct rumble and vibration through the steering wheel. This immediate tactile feedback is highly effective at alerting drowsy or distracted drivers, preventing run-off-road accidents and head-on collisions on undivided regional routes.
The Irish Driver Theory Test frequently asks candidates to identify what specific colours of road studs represent on motorway and dual carriageway layouts. Memorizing the layout is crucial: always expect red on your far left, amber on your far right, white between your lanes, and green where lanes merge or split. Misidentifying these colours can lead to costly mistakes on your exam and dangerous lane positioning in real life.

'Cat's eyes' is the common, colloquial term used in Ireland for raised pavement markers. They are retroreflective studs that bounce headlight beams back to drivers, mapping out the road path in dark or wet conditions.
In Ireland, white studs separate lanes or mark the centre line; red studs mark the left-hand edge (hard shoulder); amber studs mark the right-hand edge (central reservation/median); and green studs mark exit/entry slip roads or lay-bys.
They are physically raised above the tarmac so that if your tyres drift over them, they generate a rumble sound and tactile vibration to warn you of unintentional lane departure.
Yes, blue raised pavement markers are occasionally used to mark slip roads, access lanes, or parking zones reserved specifically for emergency services, such as the Gardaí or fire services on motorways.
