Understanding a roundabout rule is not the same as teaching a learner to apply it in traffic. An effective instructor connects the legal requirement to observation, gap selection, speed management and a safe exit plan.
Start with the actual give-way rule
In South Australia, drivers entering a roundabout must give way to vehicles already on it. The rule is not simply “give way to the right”. A vehicle approaching from the right may be important to your decision, but it is the position and movement of traffic that determine whether entry is safe and lawful.
An instructor should ask the learner to identify vehicles already circulating, potential entrants, bicycle riders and the likely paths of those road users. Encourage a decision based on the complete picture, rather than the location of one vehicle.
Teach observation before acceleration
A useful coaching sequence is: identify the intended exit, select the approach lane, adjust speed early, scan the roundabout, identify a safe gap and enter only when appropriate. The student should be ready to stop without panic, but should also avoid unnecessary hesitation once a safe gap has been identified.
Avoid turning the lesson into a simple instruction to “look right”. That may cause the learner to overlook traffic already circulating from another part of the roundabout or road users in an adjacent lane.
Multi-lane roundabouts require early planning
At multi-lane roundabouts, signs, lane arrows and the intended exit determine the correct approach lane. The learner should normally complete lane selection before reaching the entry, rather than making a late correction near the give-way line.
Teach signalling as a separate, observable skill. Left and right approach signals depend on the intended movement; a left signal should be given when leaving the roundabout if practicable. A signal does not give permission to enter an unsafe gap.
Watch for three recurring errors
Fixating on one direction: The student keeps looking right and misses an emerging risk elsewhere. Correct this with a deliberate scan across relevant approaches.
Arriving too quickly: The learner reaches the entry at a speed that leaves no comfortable option to stop. Practise early deceleration well before the roundabout.
Copying the car in front: The student follows another vehicle without making a fresh, independent give-way decision. Ask the learner to reassess once the lead vehicle moves.
A short coaching exercise
Before entering a quiet roundabout, ask the learner to explain which exit they need, which lane they will use and where they plan to look. After the manoeuvre, ask: “What made that gap safe?” The aim is not memorised language; it is a defensible driving decision supported by observation.
Good roundabout instruction produces a learner who can make safe decisions at unfamiliar roundabouts, not merely repeat a route practised with an instructor.
