Indicators at Mini and Medium Roundabouts: A Simple Guide for Learner Drivers
One of the questions we hear most often from learner drivers is:
"When should I use my indicators on a roundabout?"
It's a great question, because indicators are one of the easiest ways to communicate with other road users. Used correctly, they help traffic flow smoothly and safely. Used incorrectly, however, they can confuse other drivers, cyclists and pedestrians. During your practical driving test, poor or misleading signalling could even result in a serious fault if it causes another road user to react.
Let's make it simple!
Why do we use indicators?
Indicators are not there to help you remember where you're going. The indicators are there to tell other people what you intend to do.
Every time you signal, ask yourself one simple question:
"Who will benefit from my signal?"
If your indicator helps another road user understand what you're about to do, then use it. If it could mislead or confuse someone, think carefully before signalling.
Before entering a roundabout
The direction you are taking determines whether you should signal before entering.
Taking the first exit (turning left)
Signal left as you approach the roundabout. Keep your left indicator on throughout the roundabout until you leave.
This clearly tells everyone that you're taking the first exit.
Going straight ahead
In most cases, do not signal as you approach. Drive into the appropriate lane and maintain your position. Once you have passed the exit before yours, check your mirrors and signal left to show that you're leaving the roundabout.
Turning right or taking the last exit
Signal right on approach. Keep the right indicator on while travelling around the roundabout. After passing the exit before yours, check your mirrors, cancel the right signal if necessary, and signal left before leaving.
Why signalling at the wrong time is dangerous
Incorrect signalling causes confusion. Imagine you're waiting to join a roundabout. You see a car approaching with its left indicator flashing, so you expect it to leave at the first exit. You begin to move, but the driver continues around the roundabout instead. That “small” mistake could easily lead to a collision. Similarly, failing to signal when leaving a roundabout may cause waiting traffic to miss a safe opportunity to join.
Common mistakes learner drivers make
Here are some of the most common errors we see during driving lessons:
- Signalling left too early when going straight ahead.
- Forgetting to signal left when exiting.
- Leaving the right indicator on after passing the intended exit.
- Signalling automatically without checking whether anyone will benefit.
- Forgetting to check mirrors before changing the signal.
Could this make you fail your driving test?
Yes, it could. The examiner is not marking whether you simply use the indicator. They are assessing whether your signal is necessary, correct and helpful.
You could receive a driving fault if your signalling is late, unnecessary or forgotten.
If your incorrect signal causes another road user to brake, change direction or hesitate unnecessarily, it could become a serious fault, which would result in a failed driving test.
Remember, it's not the indicator itself that causes the fail; it's the effect your signal has on other road users.
A simple rule to remember
Whenever you approach a roundabout, remember this:
- Left exit? Signal left.
- Straight ahead? No signal on approach. Signal left after passing the previous exit.
- Right or last exit? Signal right on approach, then left before leaving.
Always combine good signalling with effective mirror checks and good observation.
Final thoughts
Indicators are one of the simplest but most important ways of communicating with other road users. They help everyone understand your intentions and make the roads safer for all.
As you gain experience, using your indicators correctly will become second nature. Until then, don't just ask yourself, "Should I indicate?" Ask yourself, "Will this signal help someone?"
That single question will help you become not only a better learner driver but also a safer driver for life.
