Is a pedestrian allowed to walk on the right side of a road outside a built-up area?

Normally, pedestrians walking on roads outside built-up areas must do so on the left side of the road. However, if for safety reasons they consider it more appropriate to walk on the right side (for example, due to the absence of a hard shoulder on the left side), they may do so. In the case of persons pushing a two-wheeled cycle or moped, hand carts or similar, persons in wheelchairs, and groups of pedestrians, they shall keep to the right and obey the signals applicable to them.
