Teaching a U-turn starts with a legal-location decision. A learner who has excellent steering control can still make a serious road-law error by choosing a prohibited place or beginning without sufficient visibility. The instructor should treat location selection, give-way and vehicle control as three separate skills.
Check legality before teaching the movement
The South Australian Driver’s Handbook identifies restrictions including U-turns at traffic lights without a U-turn Permitted sign, across prohibited continuous dividing lines or dividing strips, and on a one-way road. Current amendments also prohibit U-turns at certain crossings, including children’s crossings, level crossings, marked foot crossings and pedestrian crossings. A traffic-light-controlled meeting of a road and a road-related area has its own restriction unless signed as permitted.
Teach learners to look at road signs, road markings, traffic controls, width and visibility before setting up. A space that physically fits the vehicle is not automatically a lawful place to turn.
Give-way rules include an important exception
The general U-turn rule requires giving way to other vehicles and pedestrians. However, South Australia’s 2024 amendments clarified priority for vehicles already on the road relative to vehicles entering from adjacent land or a road-related area: the entering driver must give way to a driver making a U-turn on the road. This exception is a reason not to publish an absolute claim that a U-turning driver must always give way to every other vehicle in every circumstance.
For practical teaching, the learner must still select a clearly safe gap, remain alert to pedestrians and avoid starting where the manoeuvre would unreasonably obstruct traffic. Legal priority never removes the need to prevent a collision.
Make a clear decision before steering
Ask the learner to state: “Is the location legal? Can I see far enough? Whose path might conflict? Can I finish without reversing?” When one answer is uncertain, choose another location or wait. Then coach a suitable signal, final observation and a controlled turn.
Avoid turning the exercise into a test of whether the steering wheel can reach full lock. An instructor can change the site or practise low-speed steering separately if the learner is not ready to combine all the demands.
Debrief one decision at a time
After completion ask what made the site legal, why the gap was safe and what might have changed the decision. Record concrete observations, such as a missed No U-turn sign or late identification of an approaching cyclist, rather than simply “poor U-turn”.
