DentroTest · Accepted Answer

In adverse weather conditions, it is vital to distinguish between different degrees of intensity to use the correct lighting. In heavy rain, the driver must have the position and dipped beam lights on. Optionally, it is permitted to switch on the front fog light. It is important to remember the rule: Light/Normal Rain: Dipped beam only (Fog lights prohibited). Heavy Rain: Dipped beam mandatory Front fog optional (Rear fog PROHIBITED). Very Heavy Rain: Dipped beam mandatory Front fog optional Rear fog MANDATORY. Therefore, in 'heavy rain', only the front fog light is permitted to be added.
