DRIVING ON A ROUNDABOUT

Stop only if you have to give way: look ahead, crawl to the hold line, and completely stop as soon as the hold line disappears under the hood (i.e. within 1 meter);

if you do not have to give way, do not stop.

“Give Way at Roundabout” sign is of the same shape, as the “Give Way” sign, and hold line at a roundabout entrance is the same as the “Give Way” line, and their prescription is identical: slow down and be prepared to stop if you may present obstruction to others.

Provided that you do not have to give way, you should not stop; moreover, if you stop when you could go you risk to fail the driving test.

If you have to stop, stop as soon as the hold line disappears under the hood, and remain stationary until the way clears (do not crawl).

On a single-lane roundabout move bearing to the central island.

Do not get into psychological trap of bearing to the left side of the circle as you do in any left-hand drive road, as moving along the outer border of the roundabout makes the manoeuvre awkward, and increases risk of collision with waiting cars.

On the other hand, take care not to mount the central island.

If you plan to continue straight ahead, exiting steer into the second lane.

On a multi-lane roundabout do not change lanes, and exit in the same lane in which you entered.

This is explicitly required in NSW (Ref.#4 p.67), SA (Ref.#8 p.67, 68), VIC (Ref.#12 p.46) and WA (Ref.#14 section 3.11.3, p.64, 65).

Though ARR (r.117), as well as Australian Capital Territory, Tasmanian and Queensland road rules (Ref.#2  p.47; Ref.#10 p.37; Ref.#7 p.115) do not prohibit changing lanes inside a multi-lane roundabout, it is risky, and additional signalling needed to change lanes is misleading to other drivers.

Changing lanes while exiting a multi-lane roundabout incurs high risk of collision with other cars.

Lightly press the lower third of the accelerator pedal, and accelerate to the allowed speed.

You significantly reduce speed on the roundabout, and accelerate as soon as you exit to facilitate traffic.
