When an instructor supervises a learner driver on a public road, the instructor must ensure that:

1. The learner drives only below 20 km/h at all times
2. The learner holds a valid provisional licence for the class, L-plates (learner signs) are displayed, and the instructor is properly certified and fit to supervise
3. A second experienced driver follows in another car
4. The lesson takes place only at night when roads are empty
