Why this is the answer
The correct answer in the official bank: You are permitted to turn on the fog lights.
Fog lights are meant to improve visibility, and how well the vehicle stands out, when visibility is limited. Examples are fog, heavy rain or a dust storm. So you are permitted to turn them on in heavy rain. The main (high) beam reflects off the raindrops and dazzles. Also, you are not required to drive at half the speed limit. Instead, adjust your speed to the road conditions and visibility.
