Roundabouts are one of the trickiest parts of the driving test for learner drivers in the Hills District. If you have driven through Castle Hill, Kellyville or Norwest during peak hour, you will know exactly why.
Busy multi-lane roundabouts like those on Victoria Avenue (Castle Hill), Green Road (Kellyville) and Norwest Boulevarde (Norwest) catch out experienced drivers, let alone learners preparing for a test. Add school traffic, buses feeding the Metro and a steady stream of tradies on Old Northern Road, and the margin for hesitation gets very small.
At Green and Gold Driving School, our instructors run lessons built specifically around these local roundabouts, so students arrive at test day already familiar with them.
Below is a full breakdown of the NSW roundabout rules, the mistakes that cost learners marks, and local tips for the Hills District’s busiest intersections.
Quick summary: the roundabout rules in 30 seconds
| Situation | On approach | Inside | On exit |
| Turning left | Indicate left, use the left lane | Keep indicating left | Indicate left, then cancel |
| Going straight | No indicator, any lane unless arrows say otherwise | No indicator | Indicate left, then cancel |
| Turning right or U-turn | Indicate right, use the right lane | Keep indicating right | Indicate left, then cancel |
The one constant: you signal left before every exit, every time, if it is practical to do so.
Entering a roundabout safely
As you approach any roundabout in Castle Hill or the surrounding Hills District suburbs, you need to:
Slow down early and be ready to give way to vehicles already on the roundabout. Braking late is one of the clearest signs to an assessor that you have not read the intersection.
Scan as you approach. Look to your right, then across to the opposite side, and read the flow of traffic. On a multi-lane roundabout you also need to check what lane other drivers are in and whether they are indicating.
Decide early whether you need to stop completely or whether there is a safe gap to enter.
This scanning habit matters most on roundabouts like Victoria Avenue, where several lanes of traffic converge during school and commuter peaks.
A practical tip our instructors use: aim to arrive at the give way line at a speed you could stop from comfortably, but keep the car rolling if the gap is there. Learners who crawl to a dead stop at every roundabout lose flow, frustrate the traffic behind them, and often end up rushing the entry as a result.
Giving way on a roundabout
You must give way to all vehicles already on the roundabout.
Most people learn this as “give way to the right,” which works as a shortcut but is not the actual rule. On larger roundabouts, a vehicle that entered ahead of you from another direction may still be circulating and heading into your path. Look at where cars actually are and where they are going, not just at the entrance on your right.
Only enter once there is a genuine, clear break in traffic. Do not force your way in, even if traffic banks up behind you. Patience here is one of the most heavily assessed skills during a Castle Hill driving test.
Lane position and turning rules
Turning left. Indicate left on approach and use the left lane, unless road arrows show otherwise. Keep indicating left as you go around, and exit from the left lane.
Going straight ahead. You can use any lane on approach, unless arrows mark that lane for left or right turns only. No indicator is needed when entering.
Turning right or making a U-turn. Indicate right on approach and use the right lane, unless arrows direct otherwise. Keep indicating right as you travel around the roundabout, then switch to a left indicator before your exit. A U-turn at a roundabout is treated exactly the same as a right turn.
The painted arrows on the road override the defaults every time. Large arterial roundabouts often have their own lane arrangements, so read the road surface on approach rather than as you arrive.
Changing lanes inside a roundabout
This is the part most guides skip, and it comes up constantly on multi-lane roundabouts around Norwest and Castle Hill.
You can change lanes inside a roundabout, but only where the line between lanes is broken. If the line is unbroken, you must stay in your lane.
Where a lane change is permitted, you must:
- Indicate
- Check your mirror and your blind spot
- Give way to any vehicle already in the lane you are moving into
The better approach is to avoid it entirely. Plan your lane before you enter, and if you realise you are in the wrong one, simply go around again and take the correct exit on your second pass. It costs you about fifteen seconds and it is far safer than cutting across a lane at the last moment.
Indicating correctly, on entry and exit
Incorrect indicator use is one of the most common reasons learners lose marks on a driving test in Castle Hill, Kellyville or Norwest.
Entering: indicate left for a left turn, indicate right for a right turn or U-turn, and use no indicator if you are going straight ahead.
Exiting: always indicate left just before your exit, whether you turned left, went straight, or turned right. Cancel the indicator as soon as you have fully left the roundabout.
That exit signal is the single most useful piece of information you give other drivers. It is the only clue a driver waiting to enter has about what you are about to do. Without it, they wait, and on a busy Saturday at Victoria Avenue that is exactly how the queue builds.
Cancelling matters too. A left blinker still flashing down Old Northern Road tells every side street ahead that you are turning in, and eventually one of them will believe you.
Pedestrians at roundabouts
Roundabouts are not just about the cars.
If there is a marked pedestrian crossing on an approach or exit, you must give way to pedestrians on it. Even where there is no crossing, you must give way to any pedestrian already crossing the road you are turning into.
Around Castle Hill’s town centre, the Metro station and the shopping precincts, foot traffic near roundabout exits is constant and often distracted. Slow entry and exit speeds buy you the time to see them.
Cyclists at roundabouts
A rule that surprises a lot of drivers: at a roundabout with two or more lanes, a cyclist is permitted to turn right from the left lane. They must give way to any vehicle leaving the roundabout at each exit.
So if you are in the right lane preparing to exit and there is a cyclist tracking around the outside of you, do not assume they are turning left. Check before you cut across to your exit.
This comes up regularly on weekends, when the Hills gets heavy cycling traffic heading out toward Dural, Glenorie and Wisemans Ferry.
Long vehicles and “do not overtake turning vehicle”
Trucks and buses 7.5 metres or longer may display a DO NOT OVERTAKE TURNING VEHICLE sign on the back.
These vehicles often need to straddle more than one lane to get around a roundabout. When one is indicating, do not try to squeeze past it, and give it room to swing wide. The gap you are driving into is usually about to close as the trailer tracks across it.
Single-lane roundabouts and mini roundabouts
Not every roundabout in the Hills is a multi-lane monster. Plenty of the residential streets through Glenhaven, Cherrybrook and West Pennant Hills have small single-lane roundabouts.
The rules are the same, with two practical differences:
- Lane choice is not a decision, so all your attention goes on the give way and the exit signal.
- The circle is tight, so steering input is larger and speed needs to be lower.
Learners often treat these as too easy to bother indicating on. Assessors notice.
Common roundabout mistakes on the driving test
From our instructors, the errors that come up most often:
- Not signalling left on exit. The most frequent single fault.
- Leaving the indicator on after exiting.
- Stopping at a clear roundabout. Unnecessary stopping is marked down.
- Choosing the wrong lane on approach, then correcting inside the roundabout.
- Entering too fast, which forces heavy braking at the give way line.
- No head check before changing lanes on a multi-lane roundabout.
- Missing a pedestrian on the exit while focused on the traffic behind.
- Signalling right on entry when going straight, which misleads everyone else.

Frequently asked questions
Do I need to indicate when going straight through a roundabout?
No. When entering a roundabout to go straight ahead, no indicator is required. However, you must still indicate left just before exiting, if it is practical to do so.
What lane should I use to turn right at a roundabout in Castle Hill?
Use the right-hand lane on approach and indicate right before entering, unless road arrows direct otherwise. Keep the right indicator on as you travel around, then switch to left before your exit.
Which roundabouts are common on Castle Hill driving tests?
Roundabouts on Victoria Avenue (Castle Hill), Green Road (Kellyville) and Norwest Boulevarde (Norwest) are regularly encountered on local test routes, and all three get busy during peak hour.
Can I change lanes while I am on a roundabout?
Yes, but only where the line between lanes is broken. You must indicate, check your blind spot, and give way to any vehicle already in the lane you are moving into. If the line is unbroken, you must stay in your lane.
What happens if I end up in the wrong lane on a roundabout?
Do not cut across at the last second. Continue around the roundabout and take your exit on the next pass. On a driving test, a calm second lap is treated far more favourably than an unsafe lane change.
Do I have to give way to the right at a roundabout?
Not exactly. The rule is that you give way to any vehicle already on the roundabout that is in your path. That is usually traffic coming from your right, but on larger roundabouts it can include a vehicle that entered before you from another direction.
Do I need to stop at a roundabout?
Only if you cannot enter safely. A roundabout has a give way line, not a stop line. If there is a clear gap, you should proceed without stopping. Stopping unnecessarily can cost you marks on the test.
What is the speed limit on a roundabout?
There is no specific roundabout speed limit. The posted limit for that road applies, but you must drive to the conditions, which almost always means considerably slower than the limit while negotiating the roundabout.
How do I handle a roundabout with traffic lights?
Some larger roundabouts have signals on one or more approaches. Obey the lights first, then apply the normal roundabout rules once you are on the roundabout.
Can a cyclist turn right from the left lane?
Yes. At a roundabout with two or more lanes, a cyclist may turn right from the left lane, but must give way to any vehicle leaving the roundabout at each exit. Drivers should check for cyclists on the outside before cutting across to an exit.
What is the penalty for not indicating at a roundabout?
Failing to signal correctly is an offence in NSW and carries a fine and demerit points. Penalty amounts are reviewed regularly, so check the current figures on the Transport for NSW or Service NSW website.
How many lessons will I need to feel confident on roundabouts?
It varies. Most learners see a noticeable improvement within two or three focused sessions, because roundabout confidence is mostly about repetition at real locations rather than new theory. If roundabouts are the one thing holding you back, a targeted lesson is usually more efficient than general practice.
Road rules and penalties are current at the time of writing. Always check transport.nsw.gov.au for the latest NSW road rules.
