When is it mandatory to use headlights in Italy?

Using headlights during the day in tunnels and when visibility is poor is mandatory in Italy for safety reasons. This regulation ensures that vehicles are more visible to other road users, reducing the risk of accidents, especially in situations where natural light is limited or when driving through enclosed spaces such as tunnels.

There are specific scenarios where visibility can be significantly compromised, such as adverse weather conditions like rain, fog, or snow, as well as in tunnels where lighting may not be sufficient. The intent behind this requirement is to increase safety on the road and enhance the visibility of vehicles, making it a crucial aspect of driving regulations in Italy.

While there are times when headlights are used continuously, such as during night driving, the requirement to use them at all times, only at night, or strictly in cities does not reflect the full scope and intent of the law. The focus on daytime use in tunnels and when visibility is poor aligns with best practices in traffic safety.
