Part 9 Roundabouts

109   What is a roundabout

A roundabout is an intersection:
(a)  with either:
(i)  one or more marked lanes, all of which are for the use of vehicles travelling in the same direction around a central traffic island, or
(ii)  room for 1 or more lines of traffic travelling in the same direction around a central traffic island, and
(b)  with or without a roundabout sign at each entrance.
Note 1. Intersection, marked lane, traffic and traffic island are defined in the Dictionary.

Roundabout sign

110   Meaning of halfway around a roundabout

A driver leaves a roundabout halfway around the roundabout if the driver leaves the roundabout on a road that is straight ahead, or substantially straight ahead, from the road on which the driver enters the roundabout.

111   Entering a roundabout from a multi-lane road or a road with 2 or more lines of traffic travelling in the same direction

(1)  A driver entering a roundabout from a multi-lane road, or a road with room for 2 or more lines of traffic (other than motor bikes, bicycles, motorised wheelchairs or animals) travelling in the same direction as the driver, must enter the roundabout in accordance with this rule.

Maximum penalty: 20 penalty units.

Note. Multi-lane road is defined in the Dictionary.
(2)  If the driver is to leave the roundabout less than halfway around it, the driver must enter the roundabout from the left marked lane or, if the road is not a multi-lane road, as near as practicable to the left side of the road.
Note. Marked lane is defined in the Dictionary.
Example. 

Example 1

Leaving a roundabout less than halfway around it

(3)  If the driver is to leave the roundabout more than halfway around it, the driver must enter the roundabout from the right marked lane or, if the road is not a multi-lane road, from the left of, parallel to, and as near as practicable to, the dividing line or median strip.
Example. 

Example 2

Leaving a roundabout more than halfway around it

(4)  If the driver is to leave the roundabout halfway around it, the driver may enter the roundabout from any marked lane or, if the road is not a multi-lane road, anywhere on the part of the road on which vehicles travelling in the same direction as the driver may travel.
Example. 

Example 3

Leaving a roundabout halfway around it

(5)  Despite subrules (2) to (4), if the driver is entering the roundabout from a marked lane and there are traffic lane arrows applying to the lane, the driver must:
(a)  if the arrows indicate a single direction—drive in that direction after entering the roundabout, or
(b)  if the arrows indicate 2 or more directions—drive in one of those directions after entering the roundabout.
Note. Traffic lane arrows is defined in the Dictionary.
Examples. 

Example 4

Roundabout with 3 entry points

Example 5

Roundabout with 5 entry points

Note 1 for examples 4 and 5. Rule 116 requires a driver to obey traffic lane arrows when driving in or leaving a roundabout.
Note 2 for examples 4 and 5. The rules in Part 11 about driving in marked lanes, and moving from one marked lane or line of traffic, apply to a driver driving in a roundabout—see rules 146 to 148.
(6)  Subrule (3) does not apply to the rider of a bicycle or animal.
Note. Bicycle is defined in the Dictionary.
(7)  Subrule (5) does not apply to the rider of a bicycle or animal if the rider is to leave the roundabout more than halfway around it.
(8)  Despite subrule (2), a driver may approach and enter the roundabout from the marked lane next to the left lane as well as, or instead of, the left lane if:
(a)  the driver’s vehicle, together with any load or projection, is 7.5 metres long, or longer, and
(b)  the vehicle displays a do not overtake turning vehicle sign, and
(c)  any part of the vehicle is within 50 metres of the nearest point of the roundabout, and
(d)  it is not practicable for the driver to leave the roundabout less than halfway around it from within the left lane, and
(e)  the driver can safely occupy the next marked lane and can safely leave the roundabout less than halfway around it by occupying the next marked lane, or both lanes.
(9)  Despite subrule (3), a driver may approach and enter the roundabout from the marked lane next to the right lane as well as, or instead of, the right lane if:
(a)  the driver’s vehicle, together with any load or projection, is 7.5 metres long, or longer, and
(b)  the vehicle displays a do not overtake turning vehicle sign, and
(c)  any part of the vehicle is within 50 metres of the nearest point of the roundabout, and
(d)  it is not practicable for the driver to leave the roundabout more than halfway around it from within the right lane, and
(e)  the driver can safely occupy the next marked lane and can safely leave the roundabout more than halfway around it by occupying the next marked lane, or both lanes.
(10)  In this rule:

left lane means:

(a)  the marked lane nearest to the far left side of the road, or
(b)  if there is an obstruction (for example, a parked car or roadworks) in that marked lane—the marked lane nearest to that marked lane that is not obstructed.

marked lane, for a driver, does not include a special purpose lane in which the driver is not permitted to drive.

right lane means:

(a)  the marked lane nearest to the dividing line or median strip on the road, or
(b)  if there is an obstruction (for example, a parked car or roadworks) in that marked lane—the marked lane nearest to that marked lane that is not obstructed.

(c)  the driver is about to leave the roundabout.

Maximum penalty: 20 penalty units.
