Key Takeaways
- Green reflective studs mark the start and end of slip-roads, the edge of the main carriageway, and lay-by locations on major roads.
- Red studs indicate the left boundary of the motorway, separating the left-hand lane from the hard shoulder.
- Amber studs, positioned on the far right, highlight the boundary between a lane and the central reservation.
- White studs show the boundaries of every road lane.
- Fluorescent green/yellow studs signal changes in road layout ahead, such as roadworks or temporary adjustments.
Reflective studs, also known as cat's eyes, are those small but significant markers on the motorway that play a pivotal role in guiding thousands of drivers every night. Quietly introduced in the early 20th century, reflective studs enhance safety for motorists.
Yet, if you're learning to drive, it might not be all that obvious why reflective studs on motorways and major roads come in different colours.
But before I dive in and talk about what the different types of reflective studs are for, let’s briefly recap what reflective lights actually are.
What Are Reflective Studs On Motorways?
Reflective studs are small lights that sit in various positions across the road and shine brightly when a car's headlights hit them. They show where the edges of lanes are and where you can change lanes, which helps to keep drivers safe, especially at night or in bad weather where visibility is reduced.
Typically, you can find reflective studs on major roads, including motorways, dual carriageways, A roads, B roads, and even at some roundabouts and junctions.
They have a plastic shell with reflective materials like glass beads inside which reflect the light. Cat's eyes also come in various colours.
What Colours are the Reflective Studs on a Motorway?
Here’s what the reflective stud colours indicate:
Green studs: Primarily marking the start or end of slip roads, green studs guide drivers onto and off the motorway. They also show the edge of the main carriageway next to slip roads and the location of lay-bys on major roads.
Red studs: Located on the left edge of the motorway, red studs signal the boundary between the left-hand lane and the hard shoulder. They are especially important on smart motorways, where the hard shoulder may be used as a running lane or could be closed.
Amber studs: You'll find amber studs on the far right, between the lane and the central reservation (the bit of land between carriageways). On motorways with multiple lanes, amber studs show drivers their proximity to the central reservation.
White studs: White studs mark the lanes on motorways, dual carriages, and single carriageways. They help drivers to stay in the correct lane.
Fluorescent green/yellow studs: Less common but still important, fluorescent-green-and-yellow studs indicate changes to the road ahead, such as roadworks or temporary alterations in the road layout. They guide drivers safely through potentially confusing or altered traffic patterns.
Reflective studs are often strategically placed, sometimes closer together in high-risk areas like sharp bends or junctions, to increase driver awareness and safety.
How to Remember the Reflective Studs on a Motorway
I find it much easier to remember the colours and meanings of reflective studs on motorways with this handy mnemonic: MotoRWAy - think RWA.
R is for Red studs on the left edge of the road, W for White studs between lanes, and A for Amber studs on the right edge.
It's a quick and easy way to keep these colours and their meanings straight in your head.
Why Do Motorways Have Reflective Studs?
Motorways have reflective studs to increase road safety. They are designed to provide a visual, colour-coded reference for drivers and help guide them in dark, low light, and wintry conditions. They are a vital safety feature for motorways, helping drivers maintain lane discipline and spot upcoming changes in the road
Why is it Important to Learn What Motorway Reflective Studs Mean?
Knowing what these studs mean is about more than just passing your driving test. It's about being a responsible and safe driver. By understanding these colour codes, you can make better, more informed decisions on the road.
For instance, you can maintain proper lane discipline or get a heads up for road changes ahead.
Plus, it's a legal requirement to understand road markings - so it's good to get familiar with them.
Reflective Light Q&A for Learner Drivers
Studying for your theory driving exam?
Here’s some common driving theory questions about cat’s eyes and with the correct answer is.
Where are Amber Reflective Studs Found on a Motorway?
Amber reflective studs on a motorway are found on the right-hand edge of the main carriageway, next to the central reservation.
They mark out an area that should not be crossed, such as the central reservation on a dual carriageway or motorway. These studs help drivers stay in the right-hand lane and away from the central reservation when visibility is poor.
Where Would You Find Green Reflective Studs on a Motorway?
Green reflective studs on a motorway are found at locations where a vehicle can exit the main carriageway, such as slip roads, bus stops, and lay-bys.
These studs are used to notify drivers of potential adjustments to the road layout due to roadworks taking place on the motorway.
What Colours are the Reflective Studs Between Lanes on Motorways?
The reflective studs between lanes on a motorway are white.
They are used to show the separation between lanes on a motorway or dual carriageway.
