What are the regulations regarding the use of fog lights in Italy?

In Italy, the regulations regarding the use of fog lights stipulate that they are intended for use in conditions of reduced visibility, such as fog, heavy rain, or snow. Using fog lights during clear conditions can cause glare for other drivers, which is why this practice is not permitted. Therefore, the correct understanding is that fog lights are specifically designed to improve visibility in adverse weather conditions and should not be used when visibility is not significantly impaired. This ensures safe driving practices and helps maintain road safety for all users.
