Roundabouts are one of the things new drivers worry about most — and one of the easiest places for a private practice session to go wrong if it isn’t planned. This guide is for the person in the passenger seat: what the rules actually say, how to help your learner choose the right lane calmly, and a simple way to build up from a quiet roundabout to a busier one.
Why roundabouts feel harder than they are
Roundabouts ask a new driver to do several things at once — observe, choose a lane, signal, judge a gap in traffic, and steer — which can feel overwhelming even on a quiet one. That’s normal, not a sign anything is going wrong. Confidence here builds through repetition, not through trying to get it perfect first time.
The rule your learner actually needs
The Highway Code’s core roundabout rule (Rule 185) is: give way to traffic already on the roundabout, which usually means traffic approaching from the right, unless road markings or signs say otherwise. Watch out for road users already on the roundabout who may not be signalling correctly, or at all.
One update worth knowing if you learned to drive a while ago: Rule 186 now gives cyclists priority on roundabouts. Give them plenty of room, don’t attempt to overtake them within their lane, and expect them to travel more slowly than motor traffic. It’s a useful thing to point out to your learner before their first roundabout session, since it isn’t always covered in older learning materials.
Helping your learner choose the correct lane
As a general guide: the left lane is usually for turning left or continuing straight ahead, and the right lane for turning right or going full circle. But road markings and signs vary between roundabouts, so the rule is to check the actual markings every time rather than assume. It helps to read the signs together on the approach, calmly, rather than calling out lane choices at the last second.
What to say in the passenger seat
The words you use in the moment matter more than they might seem to. “Take your time, wait for a gap that feels comfortable” helps a learner stay calm and make a good decision. “Go now, go now” tends to produce a rushed, unsafe pull-out. It’s completely fine for your learner to wait for a gap they’re confident about — rushing is what usually causes mistakes, not caution.
If you want a fuller set of ready-to-use phrases for roundabouts and thirteen other common in-car moments, the Parent Passenger Seat Scripts pack covers exactly this — what to say, and what to avoid, worked out in advance rather than improvised mid-drive.
A simple practice progression
- Start with a single mini roundabout on a quiet road, or an empty car park to walk through lane positioning without live traffic.
- Move to a single-lane roundabout with light traffic once the basics feel comfortable.
- Only progress to multi-lane or busier roundabouts once your learner feels confident and their instructor agrees they’re ready — private practice works best when it reinforces what’s already been taught in lessons, not when it gets ahead of it.

If they take the wrong lane
It happens, and it’s rarely a serious problem. If your learner safely ends up in the wrong lane, the safer option is to continue in the lane they find themselves in and go the direction that lane takes them (either off at an earlier exit if in a lane too far to the left of where they meant to be or to go fully around the roundabout to find the correct exit again if over too far to the right) rather than make a sudden, unsafe correction. It’s worth saying this to them before it happens, so it doesn’t catch them off guard the first time.
Check the basics are in place first
Before any practice session, it’s worth confirming you’re covered on the essentials — insurance, L-plates, and who’s legally allowed to supervise. The Legal & Safety Checklist runs through all of it in a few minutes.
