Yes, you indicate on a mini-roundabout, but the timing and necessity depend on your direction: signal left for the first exit or when turning left, signal right for right turns/U-turns, and for going straight ahead, you often don't need to signal on approach but should signal left as you pass the exit before yours to show you're leaving, though it's acceptable not to if time is tight and your position is clear, prioritizing control. The key is to use indicators to help others understand your intentions, checking mirrors and surroundings before signaling.
Indicate on what direction you're going, there is no need to indicate when leaving a mini roundabout as they're usually too small for anyone to benefit from the indication.
So other drivers know what you intend to do, you must indicate when turning at a roundabout. Continue to indicate as you turn. When you leave, you must indicate left, if practical. Stop indicating as soon as you have left the roundabout.
Mini roundabouts should be treated the same as all roundabouts. You should not drive over the dot unless your vehiicles size prevents you from doing so. That being said there have been many times where I have been going straight and have just driven over the dot rather than around it.
Ensure you're signalling in the direction you want to take before entering the roundabout, unless you're travelling straight on, in which case you don't need to signal until you pass the exit before the one you are going to use.
The golden rule
You approach the roundabout from the 6 o'clock position, entering the roundabout by turning left so that you go around in a clockwise direction, while at the same time, giving way to traffic coming from your right, who are already on the roundabout.
Failing to give way:
This is by far the most common mistake drivers make on roundabouts. Remember, drivers already in the roundabout have the right of way, so give way to them before entering.
Mini-roundabouts.
Approach these in the same way as normal roundabouts. All vehicles MUST pass round the central markings except large vehicles which are physically incapable of doing so. Remember, there is less space to manoeuvre and less time to signal. Avoid making U-turns at mini-roundabouts.
The four essential rules for roundabouts are: Slow Down, Give Way to traffic already inside (including pedestrians/cyclists), Use the Correct Lane (left for left/straight, right for right/U-turn, following signs), and Signal your intention to exit by indicating left just before your exit, as noted by Transport Victoria, NSW Government, and RAC WA.
In Australia, when approaching a roundabout, slow down, give way to vehicles already in the roundabout (especially those from the right), select the correct lane based on your exit, indicate your intentions, and follow road arrows, signaling left as you exit. Always yield to traffic already circulating, use indicators for turns (left for straight/left, right for right/U-turn, then left to exit), and obey lane arrows on multi-lane roundabouts.
Approaching the roundabout
Roundabouts Rules
If a multilane roundabout, choose your lane based on your intended exit. Watch for pedestrians and cyclists and be ready to stop at the crosswalk. Signal left or right to warn other drivers if you intend on turning at the roundabout (no signal if you plan to proceed straight through the roundabout).
At every mini roundabout, we must give priority to traffic approaching from our right. This rule stays consistent whether we're turning left, going straight ahead, or turning right. Traffic already on the roundabout always has priority over vehicles waiting to enter.
12 o'clock rule for roundabouts
The easiest way to remember which lane you need to be in on a roundabout, is to think of the roundabout. As a clock. We split the roundabout down the middle. If the exit you require is 12 o'clock or before you need the left hand lane.
Driving Tips for Compact Roundabouts
Although normal roundabout rules apply, there might not be enough space or time to give a meaningful signal. When exiting the roundabout, always consider a signal but take care not to mislead other road users.
Roundabout signs
Mini roundabout sign (blue circle): Found at smaller junctions, often in towns or residential areas. This sign warns of a smaller roundabout where you must give way to the right and manoeuvre at much lower speeds.
As the mini-roundabout works on the principle of 'priority to circulating traffic from the right', a minor traffic flow can be given priority over a major traffic flow that would otherwise dominate the junction.
indicate you want to turn right as you approach the roundabout. if possible, indicate left just before the exiting the roundabout. keep indicating until you have left the roundabout.
Multi-lane roundabouts should be approached the same way as any other intersection. To turn left, use the left-most lane and signal for a left turn. To turn right, use the right-most lane and signal for a right turn.
Avoid failure to yield
To proceed into the roundabout, entering drivers must yield to all traffic from the left, waiting until all traffic from the left is clear. Entering drivers are not permitted to enter alongside cross traffic, because both lanes of cross traffic are allowed to exit the roundabout.
Hesitation. If you're unsure when to pull out of a junction, or at a roundabout, you won't fail for not going at the first viable opportunity. Try to keep your cool and pull out the next time it's safe to do so. You won't get a minor for holding up the flow of traffic if you miss the chance once, or even twice.
