Roundabout Rules – All You Need To Know 


Navigating roundabouts in the UK requires understanding specific rules to ensure safety and traffic flow. The Highway Code outlines general rules applicable to all roundabouts, including priority, signalling, and lane usage. For multi-lane roundabouts, choosing the correct lane based on your exit is crucial.


Mini roundabouts demand the same level of caution but expect quicker decision-making because of their compact size. Signalling at roundabouts is essential for informing other road users of your intentions, enhancing overall safety and efficiency on these circular intersections.


Priorities at Roundabouts 


Prioritising at roundabouts involves understanding road markings and observing traffic. Road markings indicate lanes and direct you towards the correct exit. It’s crucial to look right when approaching a roundabout, as traffic from this direction has priority. Always check your mirrors and blind spots for vehicles and cyclists.


Tips for navigating roundabouts include:

  1. Choosing the right lane early, 
  2. Signalling your intentions clearly
  3. Maintaining a steady speed
  4. Adjust your observations and speed based on the roundabout’s size and traffic flow 
  5. Give way to the right 
  6. Merge when you see a safe gap
  7. These tips apply to mini roundabouts also


General Roundabout Signs Vs Direction Signs 


In the UK, roundabouts are marked by general and direction signs to aid navigation and ensure smooth traffic flow. General signs alert drivers to an upcoming roundabout, helping them prepare for entry and navigation. Direction signs provide crucial information about exits and their destinations, enabling drivers to choose the correct lane in advance.


These signs enhance road safety by reducing confusion and potential accidents, guiding drivers effectively through the roundabout towards their intended route. Understanding these signs is key to navigating roundabouts confidently and safely.


Road markings on the approach to a roundabout


Approaching a roundabout, you’ll notice several road markings designed for guidance and safety. Hatch markings indicate areas not to enter, guiding you to the correct lane. Give way markings signal where you must give-way to traffic on the roundabout. A


rrows on the road surface help direct you to the appropriate lane for your exit. These markings, combined with clear signage, ensure that drivers navigate roundabouts efficiently and safely, reducing the risk of accidents and maintaining smooth traffic flow.


Roundabout Lanes 


When approaching a roundabout, it’s crucial to check and select the correct lane early to ensure a smooth drive. Generally, if two lanes lead in the same direction, opting for the left lane is advisable unless you’re overtaking.


Choosing your lane early helps avoid last-minute lane changes, reducing hesitation and confusion for both you and other motorists. This preparation ensures that traffic flows smoothly through the roundabout, enhancing safety and efficiency for all road users.


Spiral Roundabouts 


Spiral roundabouts are designed to facilitate smooth traffic flow to major roads and intersections, forming an integral part of the ring road network. Their layout guides drivers through the roundabout, with road markings indicating the spiralling lanes that gradually lead towards exits.


It’s crucial to select the correct lane early and adhere to it, following the spiral markings that guide you to the left for exits. This system minimises confusion and congestion, ensuring drivers can safely navigate through complex junctions and continue on their desired routes.


Non-marked Roundabouts


In residential areas and town environments, where roundabouts may not have clear lane markings, it’s important to keep left unless overtaking or when your exit dictates otherwise. This practice ensures smoother traffic flow and reduces confusion among drivers, particularly in areas with smaller roundabouts or those less familiar with the layout.


Adhering to this principle aids in preventing collisions and ensures that all road users can navigate these intersections safely and efficiently.


Turning Right At General Roundabouts 


For right turns at a non-marked roundabout, ensure your vehicle is positioned towards the inside of the roundabout. As you approach, check your right mirror and signal your intention.


Continually monitor traffic from your right, maintaining your inner position. After passing the exit before yours, check your left mirror, signal left, and prepare to exit, moving your vehicle to the outer edge of the roundabout. This manoeuvring, coupled with appropriate signalling, facilitates a smooth and safe turn, clearly communicating your actions to other drivers.


Mini Roundabouts 


Mini roundabouts differ from larger ones primarily in their size and the quick decisions required due to their compact nature. At mini roundabouts, the rule of giving way to traffic from the right applies, just like at standard roundabouts.


They are often found in residential areas and urban environments where space is limited, serving as an efficient alternative to T-junctions by facilitating smoother traffic flow and reducing congestion without needing extensive road space. Their presence aims to maintain safety while maximising the efficiency of traffic movement in tighter spaces.


Signals – prior, during and exiting


Before entering a roundabout, signal left if you’re turning left, no signal if going straight but prepare to signal left after you pass the exit before yours, and signal right if turning right. Maintain your signal through the roundabout as you approach your exit.


Upon reaching the exit before the one you intend to take, check mirrors, then signal left to indicate you’re leaving the roundabout. This clear communication ensures other drivers understand your intentions, maintaining smooth traffic flow and enhancing safety for all road users.


Judgement of Merging


Judging when to enter a roundabout involves observing the positions and movements of cars already on it. Look towards your right and the 3 o’clock exit to gauge the intentions of drivers—tyre placement and signalling can indicate if they’re exiting or continuing around the roundabout.


Pay attention to the speed and road position of approaching vehicles; those tucked in and signalling right are likely not exiting immediately. Approach the roundabout at a speed that allows you to adjust or stop if needed, ensuring a safe and smooth merge onto the roundabout.


Lane changes on a spiral roundabout 


On spiral roundabouts, lane changes are guided by road markings that gradually lead you to the correct exit. Start in the lane that matches your intended exit as indicated by the signs. As you proceed, follow the spiral markings—these will naturally guide you towards the outer lanes as you approach your exit.


It’s crucial to remain observant of other vehicles, maintain a steady speed, and signal your intentions clearly. This careful observation and adherence to markings ensure smooth navigation through the roundabout.


Hazards – prior, during and after 


Navigating roundabouts involves anticipating various hazards before, during, and after your manoeuvre. Be vigilant of cyclists and slow-moving vehicles, which can affect your approach and exit speed. Non-signaling drivers and vehicles positioned incorrectly can create confusion, requiring keen observation and readiness to adjust. Sun glare and traffic lights near roundabouts can impair visibility, demanding extra caution. Pedestrian crossings adjacent to roundabouts require slow speeds and awareness, especially upon exit. Box junctions, bus, and cycle lanes near roundabouts also introduce unique challenges, emphasising the need for comprehensive attention to safely navigate these areas.




How do I signal on the approach to a roundabout going ahead?


When going straight ahead at a roundabout, generally, you do not need to signal as you approach. However, once you’ve passed the exit just before the one you intend to take, signal left to indicate you’re leaving the roundabout. This ensures other drivers and cyclists are aware of your intention to exit, contributing to smoother and safer roundabout navigation.


Do I always signal left to exit a roundabout?


Yes, it’s a good practice to always signal left just before you exit a roundabout, regardless of the direction you’re coming from. This signal informs other drivers and cyclists of your intention to leave the roundabout, promoting safety and smooth traffic flow.


There is a cycle box at the traffic lights, am I allowed to wait in it?


No, you are not allowed to wait in a cycle box at traffic lights. These boxes are specifically designed to provide cyclists with a safe space ahead of other traffic at intersections, improving their visibility and safety. Motor vehicles should stop behind the white line at the entrance to the cycle box, not inside it.


My exit is blocked, what should I do?


If your exit is blocked while you’re on a roundabout, remain calm and continue around the roundabout until you can safely exit. Never stop or reverse; instead, go around again if necessary. It’s important to keep the traffic flowing and not cause unnecessary obstruction or danger to other road users. Always stay alert and be prepared for unexpected situations like this.


I have forgotten where I am going when on the roundabout, what should I do?


If you forget your exit while on a roundabout, remain calm and continue to circle until you can safely decide on your exit. Do not stop or attempt to exit hastily, as this could endanger you and other road users. It’s important to keep moving and use the time to reassess and choose your exit safely. If necessary, take a later exit to give yourself time to think and avoid making a sudden or unsafe manoeuvre.


My Sat Nav doesn’t recognise the roundabout, what shall I do?


If your Sat Nav doesn’t recognise a roundabout, it may be due to the area being newly developed and the maps not yet updated. Stay calm, use road signs and markings to guide your decision, and safely choose a direction. In such scenarios, taking a well-judged exit to reassess and adjust your route is advisable. Always prioritise safety over following the Sat Nav when faced with unclear directions.


I have stalled just before entering a roundabout, what should I do?


If you stall just before entering a roundabout, stay calm. Quickly restart the engine, check your mirrors to be aware of traffic around you, and proceed when safe. Stalling can happen, especially in learning stages or stressful situations like busy roundabouts.


Your primary focus should be on safety and minimising disruption to other road users. If necessary, signal to drivers behind you to indicate you’re aware of the stall and working to resolve it, maintaining clear communication with those around you.


Another driver has beeped their horn, what should I do?


If another driver beeps their horn at you, stay focused and don’t panic. The beep could be a warning or a sign of impatience. Quickly assess the situation to understand why they might have beeped. If it’s for a safety reason, correct your action if necessary. Always prioritise safety over reacting to the horn, keeping your attention on the road and proceeding when it’s safe.


I have stopped just past the solid white line at the traffic lights, what should I do?


If you’ve stopped just past the solid white line at traffic lights, it’s important to stay put if moving might cause confusion or danger. Assess the situation: if you’re in a position that could pose a risk to other road users or obstruct traffic, carefully consider whether you can safely adjust your vehicle without crossing into the path of oncoming traffic or pedestrians.


If adjusting is not safe, remain stationary until the light changes, and proceed with caution. Prioritise safety and adherence to traffic rules to avoid similar situations in the future.


I am waiting at a red traffic light, do I need to move out of the way for emergency vehicles?


At a red traffic light, if an emergency vehicle approaches and you’re in the way, you should try to move safely. This might mean staying put if moving could cause an accident or hazard. Always assess the situation carefully; if there’s a safe way to make room, such as edging forward or to the side without entering the junction or causing danger, then do so.


The key is ensuring the safety of all road users while facilitating the emergency vehicle’s passage.


I have left my signal on exiting the roundabout, why is this dangerous?


Leaving your signal on after exiting a roundabout can be dangerous because it may mislead other drivers and pedestrians into thinking you’re planning to turn again or change lanes, potentially leading to confusion or accidents. It’s crucial to ensure your signals accurately reflect your intended actions to maintain clear communication and safety on the roads.


I panic when on spiral roundabouts, what should I do?


If you panic on spiral roundabouts, practising in a calm, low-traffic environment can help build confidence. Familiarise yourself with the roundabout’s layout beforehand, if possible, and remember the basics: choose the correct lane early, follow the road markings, and signal appropriately.


Taking a driving lesson specifically focused on navigating complex roundabouts can also provide tailored advice and reassurance. Gradually, as your familiarity and experience increase, your anxiety should decrease. Remember, it’s okay to take your time and ensure safety first.


What are the common mistakes learners make on their driving test with roundabouts?


Common mistakes learners make on their driving test with roundabouts include not checking mirrors and blind spots properly, failing to signal or signalling too late, incorrect lane usage or not following lane markings accurately, and either hesitating too much or being overly aggressive.


Misjudging the speed of oncoming traffic leading to unsafe entries or exits is another error. Overcoming these requires practice, observing proper roundabout etiquette, and understanding the specific rules and signals associated with navigating roundabouts effectively.
