Should a motor vehicle driver give short audible signals when overtaking a pedestrian in fog outside a built-up area?

The question is about overtaking a pedestrian in fog outside a built-up area. The driver of a power-driven vehicle should then give short audible signals. The answer is: yes.

The Road Traffic Act states that when driving in conditions of reduced visibility caused by fog, precipitation or other causes, the driver of a vehicle is obliged to exercise particular caution, and the driver of a power-driven vehicle must also switch on dipped headlights or front fog lights and, outside a built-up area in fog, give short audible signals when overtaking or passing. A pedestrian walking on the shoulder or the roadway in the same direction is a road user whom you are overtaking, so the rule applies directly. An audible signal in fog has one purpose: to warn a person who cannot see you that you are about to pass them, so that they do not step towards the roadway. It should be short - it is not a way of hurrying someone, only information. In a built-up area - also in fog - you may use the horn only in case of immediate danger.
