Why this is the answer
The correct answer in the official bank: When encountering or overtaking an animal.
The rules require you to slow down when you encounter or overtake animals, on any type of road. Animals can be frightened by a vehicle's noise and move suddenly and unpredictably into your path, so you must reduce speed and stop if needed. This duty is not limited to urban roads or heavy traffic, and it comes on top of the general duty to drive carefully.
