NSW Roundabout Rules

Roundabouts become easier when you separate the task into approach, entry, circulation and exit. Make one decision at a time and communicate the path you intend to take.

01

Approach and entry

Reduce speed, read the lane arrows and signs, scan the crossings and look for every vehicle already in the roundabout. The central rule is to give way to vehicles already circulating—not simply to look right and enter.

Choose a safe gap that lets you enter without making another road user brake or change course. Large vehicles and cyclists may need more lane space than you expect.

02

Signals for each movement

For a left turn, signal left before entering and keep signalling as you leave. For straight ahead, do not signal on approach, but signal left when exiting if practical. For a right turn or U-turn, signal right on approach, then signal left as you exit when practical.

Cancel the indicator after leaving. A signal shows intention; it does not create priority or make an unsafe lane change acceptable.

03

Multi-lane roundabouts

Follow the road arrows and signs when choosing a lane. Stay within the lane through the roundabout. If a lane change is permitted and necessary, signal and give way to traffic in the lane you want to enter.

If you miss the correct exit, continue around safely rather than stopping, reversing or cutting across another lane.

Remember

Set up in the correct lane before the roundabout. Early lane choice removes the most dangerous last-second decision.

04

Cyclists, pedestrians and long vehicles

Cyclists may occupy a full lane and can be less visible beside a vehicle. Do not squeeze past within the roundabout. Watch for pedestrians at approaches and exits, even where the roundabout itself does not create an automatic crossing priority.

A long vehicle may use more than one lane while turning. Stay out of its turning path and do not move alongside it on the side toward which it is turning.

Make the distinction

Rules learners often confuse

Compare the two ideas before answering a scenario question.

Left turn

Signal left on approach and through the exit.

vs
Straight ahead

No approach signal; signal left on exit when practical.

Right turn

Signal right on approach, then left on exit when practical.

vs
U-turn

Use the same signalling pattern and obey any U-turn restriction.

Entering

Give way to all vehicles already in the roundabout.

vs
Changing lane

Give way to vehicles already in the lane you want to enter.

Exam-day awareness

Common mistakes to avoid

Pause when one of these patterns appears in a question or on the road.

  1. 01

    Looking only to the right instead of checking the whole roundabout

  2. 02

    Choosing a lane after entering

  3. 03

    Forgetting the left exit signal when it is practical

  4. 04

    Cutting across lanes after missing an exit
