In the traffic rules, it is stated that 'drivers intending to reverse or turn around shall give way to other road users.'

You should also keep in mind the following rules regarding reversing:

If the driver's view is inadequate, they must not reverse or turn around except under the guidance of another person or unless the driver has made sure that danger or injury cannot arise as a result.

It is prohibited to reverse or turn around on motorways and motor vehicle roads or on motorway and motor vehicle road's acceleration or deceleration lanes.
