When is it mandatory to use headlights during the day in Italy?

Using headlights during the day in Italy is mandatory in tunnels and during periods of limited visibility. This regulation is designed to enhance safety by ensuring that vehicles are more visible in conditions where visibility may be compromised, such as during rain, fog, or when driving through poorly lit areas like tunnels.

This requirement helps to reduce the risk of accidents by making vehicles easier to spot by other road users. In Italy, it is particularly emphasized that while some situations might allow for driving without headlights in good visibility, certain environments, like tunnels or adverse weather conditions, necessitate their use to maintain safety standards on the road.
