As a general rule, reversing is prohibited, except in the following cases, exceptionally and always covering the minimum necessary distance:
1. As a complementary manoeuvre to stopping, parking, or joining traffic. In this case, the reversing distance may not exceed 15 metres or encroach upon a road junction.
2. When it is not possible to move forward or change direction or sense of travel. In this case there is no limit on the reversing distance, and it may even encroach upon a road junction if necessary.
The reversing manoeuvre is prohibited on dual carriageways and motorways.
