When learning to drive, one of the most confusing elements can be roundabouts. At our driving school, we often find that even experienced instructors and pupils can get puzzled by the road markings—especially when it comes to the right lane. In this article, we take a closer look at why you might not always see a right arrow painted in the right lane when approaching a roundabout and what you should do in these situations.
The Highway Code and Roundabout Lane Use
According to the Highway Code, if you’re taking an exit that is to the right on a roundabout, you should approach in the right lane unless road signs or markings indicate otherwise. However, if you’ve ever noticed, the right lane often features a head arrow instead of a right arrow. This might seem counterintuitive at first. After all, if you’re signalling for a right turn, wouldn’t a right arrow be the natural choice?
The explanation lies in the design principles outlined in the Traffic Signs Manual (Chapter 5, Section 6.7.2). The use of a head arrow in the right lane is intended to discourage drivers—particularly those from overseas who might be unfamiliar with British roundabout layouts—from turning the wrong way. Essentially, the head arrow acts as a safeguard against misinterpretation, ensuring that drivers understand they should be following the circulatory carriageway around the roundabout.
The Role of Road Markings in Driver Safety
One of the key reasons behind these seemingly contradictory markings is safety. Many roundabouts in Britain are designed so that the road naturally curves to the left. This design encourages a clockwise, or anti-clockwise, circulation. If a driver were to misinterpret a right arrow in the right lane, they might mistakenly try to cut into the wrong path, causing confusion and potential danger as two lanes converge into one.
The Traffic Signs Manual advises that on most roundabouts, the clockwise direction should be clearly apparent. As a result, even when the exit is to the right, the road markings prioritise the overall flow of traffic. This approach minimises the chance of an abrupt lane change or miscommunication between drivers—a problem that can lead to hazardous situations on the road.
Mini Roundabouts: A Slight Variation
The scenario can be slightly different when it comes to mini roundabouts. Here, you are more likely to find a right arrow painted in the right lane, as the risk of drivers turning the wrong way is considerably lower. However, even on mini roundabouts, there are instances where a head arrow is used in the right lane despite a clear right-turn requirement. This inconsistency can leave even the most cautious driver scratching their head.
For learners, it is always best to follow the basic guidance of the Highway Code: if you’re planning to exit to the right, start in the right lane—unless there is clear signage or markings to the contrary. And if you do accidentally find yourself in the wrong lane, changing lanes on a roundabout is not illegal. Just be sure to do so safely and be mindful of other road users.
Final Thoughts
At our driving school, we emphasise that understanding these road markings is crucial for safe and confident driving. While the absence of a right arrow in the right lane might seem confusing at first, it is a deliberate design choice aimed at preventing dangerous misinterpretations. By following the guidance of the Highway Code and taking extra care when approaching roundabouts, you can navigate these intersections with greater assurance.
Remember, practice and familiarity with these nuances will help you build the skills needed for safe driving. If you have any questions or need further clarification, don’t hesitate to ask one of our instructors during your lessons.
