How many warning vests must you have in the car in Italy?

In Italy, it is mandatory that every person in the vehicle must wear a warning vest if they are outside the vehicle due to a breakdown or an accident on the highway or country road. This implies that the number of warning vests carried in the car should correspond to the number of seats in the vehicle or the maximum possible number of occupants. Officially, however, only one warning vest is required in the vehicle. Nevertheless, it is recommended to carry a vest for each occupant to ensure safety for all passengers in case of an emergency. This regulation aims to increase safety during accidents and breakdowns on roads by improving the visibility of people. Violations of this regulation can be punished with fines, highlighting the importance of this safety measure.
