Show answer

Show answer
✓ Correct answer: The right lane, or as close to the centre as the vehicle size permits
Under the Australian Road Rules, a driver turning right at a multi-lane roundabout must approach in the right lane (or as near to the right as practicable), though drivers of long vehicles may need to swing wide to safely navigate the roundabout geometry.

Under the Australian Road Rules, a driver must stop at the stop line when a level crossing has flashing red lights or a lowering boom gate, and must not proceed until the signals have ceased and any gate has fully risen, ensuring the crossing is completely clear.

Show answer

Show answer
✓ Correct answer: Occupy any part of the road, including oncoming lanes, necessary to complete the turn safely

Show answer
