What do Italian law require for halted, parked, or wrecked vehicles that jeopardize traffic?

In Italy, it is required that halted, parked, or wrecked vehicles that could pose a danger to traffic be made recognizable through the use of a triangular reflecting warning sign. This regulation ensures that other drivers are alerted to the presence of a potential hazard on the road, allowing them to react appropriately to avoid accidents. Such warning signs are critical for safety as they enhance visibility in various lighting conditions and alert approaching drivers to exercise caution.

The need for immediate repairs or removal is not emphasized in this context, as the priority is on safe notification rather than immediate resolution of the vehicle's condition. While horns are important safety features for vehicles in motion, they do not serve a purpose for stationary vehicles needing to be identified as potential hazards.
