A roundabout can feel easy when the road is quiet, then suddenly feel confusing when cars are arriving from every direction. The good news is that once you understand how to use roundabouts correctly, the same calm routine works at small suburban intersections, busy multi-lane roundabouts and during your Perth driving test.
Roundabouts are designed to keep traffic moving without everyone waiting at a set of lights. Your job is not to rush through. It is to observe early, choose the correct lane, give way when required, use clear signals and leave only when it is safe.
The first rule: give way before entering
At a roundabout, you must give way to vehicles already in the roundabout. Look to your right as you approach, because traffic entering from your right will usually reach your path first.
Slow down early enough that you can properly check. Do not approach too fast and then brake sharply at the give-way line. A controlled approach gives you time to see motorcycles, cyclists, larger vehicles and cars that may be difficult to judge behind another vehicle.
If there is a safe gap, enter smoothly. If there is not, wait. Trying to force your way into a small gap is risky and can lead to a critical driving-test error. The vehicle behind you may be waiting too, but do not let that pressure make the decision for you.
Pedestrians also need your attention. At roundabouts with pedestrian crossings, check for people crossing as you enter and as you leave. Keep scanning, particularly near schools, shopping areas and residential streets.
How to use roundabouts correctly with signals
Signalling lets other road users understand where you are going. This reduces hesitation and helps traffic flow safely.
Turning left
If you are taking the first exit, indicate left as you approach the roundabout. Keep the left indicator on as you travel through and exit. Choose the left lane unless road markings or signs tell you otherwise.
Going straight ahead
When travelling straight through, do not indicate on approach. Enter in the appropriate lane, usually the left lane at a single-lane roundabout or as directed by lane arrows at larger ones.
Once you have passed the exit before the one you want, indicate left to show that you are leaving. For example, if you are taking the second exit, signal left after passing the first exit, if practical. This is one of the habits driving assessors look for because it shows you are communicating clearly with other drivers.
Turning right or making a U-turn
If you are turning right, usually taking the third exit, indicate right as you approach. Keep indicating right while you travel around the roundabout. After you pass the exit before yours, change to a left signal to show that you are leaving.
A U-turn is treated much like turning right. Check that a U-turn is permitted and that your vehicle has enough room to complete it safely. At a small roundabout, a larger vehicle may need extra space, so never sit beside a truck, bus or ute towing a trailer if it may need to swing wide.
Choose your lane before the roundabout
Lane choice becomes more challenging at bigger Perth intersections, especially where there are two or more lanes leading into and through the roundabout. The road markings, signs and directional arrows always come first.
Read them well before you reach the give-way line. If an arrow shows that the left lane is for left turns and straight ahead, do not move into it at the last second from the right lane. Make an early, safe lane change instead. If you miss your lane or exit, continue safely and find another place to turn around. Missing a turn is never as serious as making a sudden move.
At a multi-lane roundabout, stay in your lane unless road markings direct otherwise. Do not cut across lanes while circulating. Check mirrors and blind spots before entering, and keep an eye on vehicles beside you. Some drivers may choose the wrong lane or drift wide, so leave space where you can.
A calm approach routine for every roundabout
Nervous drivers often look only to the right and forget the rest of the driving task. Giving way is essential, but safe driving means maintaining awareness all around your vehicle.
Use this simple routine on approach: check your mirrors, identify your exit, read the signs and lane markings, select the right lane, signal if required, reduce speed and look right for traffic already on the roundabout. Then check for pedestrians and cyclists before entering.
This is not something you need to say out loud while driving. With practice, it becomes a natural sequence. A good routine helps prevent rushed decisions, particularly when another driver is following closely or traffic is building behind you.
Common roundabout mistakes to avoid
The most common mistake is entering without giving way to traffic already circulating. Even if another vehicle is indicating left, wait until you can clearly see that it is actually leaving the roundabout. Indicators can be forgotten or used incorrectly.
Another frequent error is failing to signal left when exiting. Drivers waiting to enter cannot always tell where you are going, so a clear exit signal makes the intersection safer for everyone.
Avoid stopping unnecessarily once you are already on the roundabout. If you have entered safely, keep moving unless a genuine hazard requires you to stop. Stopping in the circulating lane can surprise the driver behind and disrupt traffic flow.
Also avoid driving too slowly when the roundabout is clear. Caution is good, but hesitation can confuse other drivers. Aim for a controlled, steady speed that suits the size of the roundabout, your exit and the traffic conditions.
Roundabouts during a Perth driving test
A driving assessor is not expecting perfection at every busy intersection. They are looking for safe judgement, observation, vehicle control and correct road positioning.
Before a roundabout, show that you are planning ahead. Check mirrors, position the car correctly and use your indicator at the right time. At the give-way line, make a clear observation to the right. Do not rely on a quick glance if traffic is heavy. Take the time you need to make a safe decision.
When you exit, make sure your steering is smooth and your indicator is cancelled. Check that you are travelling at an appropriate speed for the new road. The roundabout is not finished until you are safely established in your lane after leaving it.
If you make a small mistake, such as signalling a little late, stay calm and continue driving safely. Do not let one error distract you for the next few minutes. A pre-test lesson or mock assessment with North East Driving School Perth can help you practise local roundabouts and receive clear feedback before test day.
Build confidence through practice
Start with quieter single-lane roundabouts, where you can focus on the basic give-way and signalling routine. As your confidence grows, practise at different times of day and in busier areas. Wet roads, low afternoon sun and heavy traffic can all change how much time and space you need.
Ask your supervising driver or instructor to give directions early at first. Once you are comfortable, practise identifying your own exit and lane from the signs. This builds the independent decision-making you need after you get your licence.
Every safe roundabout entry is built from the same steady choices: slow down, look properly, give way, signal clearly and keep moving when the gap is safe. With enough real-road practice, roundabouts stop feeling like a test and become just another part of a confident drive.
