The Different Types of Roundabout
Here in the UK, we have more roundabouts as a proportion of our road network than any other country in the world. There’s a good reason for this: roundabouts are proven to be safer than traditional junctions, with far fewer potential collision points. However, they can still be a little tricky for those unfamiliar—especially when you consider the numerous types of roundabouts you might encounter.
That’s why we’ve created this useful guide to introduce you to the different types of roundabouts. We’ll also share some top tips to help you approach each one with confidence and ease.
Single-Lane Roundabouts
When driving around your local area, you’re likely to come across a standard single-lane roundabout. These junctions occur where two or more roads meet and (as the name suggests) feature just one lane around a central island. They do not have traffic lights, though you may see road signs on your approach.
When approaching a roundabout, use the mirrors–signal–manoeuvre (MSM) routine, and decide early on which exit you intend to take, signalling appropriately.
- If taking the first exit to the left, signal left as you approach.
- If taking an exit to the right or going full circle, signal right.
When you reach the give way line, give priority to traffic coming from your right. Keep an eye on other vehicles already on the roundabout and look ahead before moving off to ensure traffic in front has done the same. When exiting the roundabout, signal left after passing the exit before the one you plan to take.
Mini Roundabouts
Mini Roundabouts operate much like standard single-lane roundabouts. The key difference is that the central island is replaced with a road marking. You must still drive around this marking—treating it as though it were a physical island.
Mini roundabouts are, as the name implies, smaller, giving you less space to manoeuvre. This means you’ll need to be extra quick with your signalling. Remember: the Highway Code discourages performing U-turns at mini roundabouts.
Did you know? A mini roundabout’s defining feature is the absence of a physical central island. A smaller roundabout with any form of street furniture would simply be considered a “small roundabout.”
Multi-Lane Roundabouts
Multi-lane roundabouts come in all shapes and sizes. The defining feature is the presence of more than one lane around the central island.
When approaching:
- Use the MSM routine.
- Decide on your exit and adjust your speed and position appropriately.
- Select the correct lane:
- For the first exit left, signal left, approach in the left-hand lane, and stay left on the roundabout.
- For exits to the right, signal right and approach in the right-hand lane. Stay right on the roundabout, only changing lanes when preparing to exit.
- For intermediate exits, choose the appropriate lane and stick to it until you need to leave. Signal left after passing the exit before the one you intend to take.
Turbo Roundabouts
Turbo roundabouts are a variation of the multi-lane roundabout that require drivers to choose their direction upon approach. The key difference is that once you select your lane, you cannot change it—effectively locking you into a predetermined path.
Typically, one lane leads to the first exit (left) while the other caters to exits further right, creating a spiral-like effect.
Turbo roundabouts remain rare in the UK—Bedford was the first major example in 2014—though they are much more common in countries like the Netherlands.
To navigate a turbo roundabout:
- Choose the correct lane in good time.
- Follow the lane markings carefully and signal only when leaving the roundabout.
Access-Controlled Roundabouts
Although roundabouts are often an alternative to traffic lights, some feature traffic lights at their entrances to manage traffic flow.
In this case:
- If the light is green, you have priority and may proceed onto the roundabout.
- Once on the roundabout, follow the usual rules for single- or multi-lane roundabouts as appropriate.
Magic Roundabouts
The Magic Roundabout design consists of several mini roundabouts arranged around a larger central roundabout. Swindon is home to the most well-known example, though others exist across southern England.
While these junctions may look intimidating, they are safer than they appear because vehicles travel slowly.
When approaching:
- Treat each mini roundabout separately.
- Follow the usual rules for roundabouts—giving way to traffic on your right and signalling when you intend to leave.
Don’t panic—take it step by step, and you’ll navigate it successfully!
Cut-Through Roundabouts
Also known as “throughabouts” or “hamburger roundabouts,” these feature a straight road running through the centre of the roundabout. Traffic lights control where the road intersects with the roundabout to ensure safety.
To navigate:
- Obey the traffic lights at all times.
- Be prepared for multiple sets of lights as you work your way around the roundabout.
Tram Roundabouts
This type of roundabout features tram tracks that cross through the centre of the junction. Examples exist in Wolverhampton, New Addington (London), and Sheffield.
While they may look unusual, you simply need to follow the standard roundabout rules and be mindful of trams where applicable.
Roundabout Interchanges
Roundabout interchanges are typically found where roads meet at different levels (e.g., motorways and A-roads). They can include stacked designs where the roundabout and roadways pass over or under one another.
Approach these junctions with care, paying close attention to road signs and lane markings.
General Tips for Roundabouts
Here’s a quick recap to help you tackle any roundabout:
On Approach:
- Use MSM: mirrors–signal–manoeuvre.
- Decide on your exit early and signal appropriately.
- Select the correct lane and adjust your speed.
At the Roundabout:
- Give way to traffic on your right (unless signs or lights indicate otherwise).
- Look ahead before moving off to ensure traffic in front has cleared.
- Watch out for cyclists, motorcyclists, pedestrians, and large vehicles.
When Exiting:
- Signal left after passing the exit before the one you plan to take.
FAQs
What lane should I use at a roundabout?
- For the first exit (left): Use the left-hand lane and signal left.
- For exits to the right: Use the right-hand lane and signal right. Signal left when you’re ready to leave.
- For intermediate exits: Use the most appropriate lane, stick to it, and signal left after passing the previous exit.
How should I signal when going straight at a roundabout?
Do not signal on approach. Normally, approach in the left-hand lane (check road markings), and signal left after passing the exit before yours.
Who has the right of way at a roundabout?
Traffic approaching from your right has priority. Wait at the give way line until it is safe to proceed.
