Roundabouts are designed to keep traffic flowing, but they are historically one of the most confusing topics for Learner drivers taking the DKT. A significant number of test failures happen because candidates misinterpret the signaling rules or lane markings.
Whether you are tackling a small single-lane circle or a complex multi-lane intersection, the rules remain consistent. Here is your definitive guide to mastering roundabouts for the NSW Driver Knowledge Test.
The Golden Rule: Giving Way
The most fundamental rule of roundabouts in NSW is often the simplest: You must give way to vehicles already in the roundabout.
- You do not specifically "give way to the right" (although that is where the traffic usually comes from). You give way to any vehicle already circling that you would potentially collide with.
- You must enter only when there is a safe gap in the traffic.
- Pedestrians: You must give way to pedestrians crossing the road you are entering or exiting.
Signaling Rules: The "Clock Face" Method
The DKT will heavily test you on when to use your indicators. Imagine the roundabout as a clock face, entering at 6 o'clock.
Turning Left (Exiting at 9 o'clock)
- Approach: Indicate Left.
- Lane: Stay in the left lane (unless marked otherwise).
- Exit: Keep the left indicator on until you have exited.
Going Straight (Exiting at 12 o'clock)
- Approach: Do NOT indicate.
- Lane: Use either lane (follow the road arrows), but the left lane is standard.
- Exit: Indicate Left just after you pass the exit before the one you want to take.
Turning Right or U-Turns (Exiting at 3 o'clock or 6 o'clock)
- Approach: Indicate Right.
- Lane: Use the right lane.
- In the Roundabout: Keep the right indicator on.
- Exit: Switch to your Left indicator just before your exit.
Multi-Lane Roundabouts
On larger roundabouts with two or more lanes, lane discipline is critical. The DKT often shows diagrams asking which car is in the correct position.
- Road Markings (Arrows): Always obey the arrows on the road. If the left lane has a "Left Turn Only" arrow, you cannot go straight from that lane.
- Changing Lanes: Generally, you should avoid changing lanes within a roundabout. However, if you must change lanes to exit, you must give way to vehicles in the lane you are moving into and signal your intention clearly.
- The "Spiral": Be careful of spiraling lanes that guide you out automatically. Do not fight the lane markings.
Common DKT Trap Questions
Watch out for these tricky scenarios often found in the test:
- "When do you signal left if going straight?" Answer: Only after you have passed the previous exit.
- "Who gives way?" Answer: The vehicle entering the roundabout gives way to the vehicle already circulating.
- "Are U-turns legal?" Answer: Yes, unless there is a "No U-Turn" sign, but you must signal right on approach and use the right-hand lane.
Practice Makes Perfect
Roundabouts are tricky on paper because you have to visualize the car's movement. Download our app to practice exact roundabout diagrams and scenarios directly from the DKT question bank.
Conclusion
Don't let a roundabout diagram spin you out on test day. Remember the basics: Give way to those in the circle, signal right for right turns, and always signal left to exit. Master this, and you are one step closer to getting your L-plates.
