South Australia · Learner's Theory Test · Road rules

You are behind a slow car on a road with a double continuous centre line and no oncoming traffic. May you cross the lines to overtake?

The answer

Yes, if you flash your lights first
No - you must not cross a double continuous line to overtake another vehicle Correct
Yes, because there is no oncoming traffic
Yes, if the vehicle ahead is travelling more than 20 km/h below the limit

Why that's the answer

You must not cross a double continuous dividing line to overtake a vehicle, even if the road ahead looks clear. The main exceptions are to avoid an obstruction or, when safe, to pass a cyclist.
