Trailers intended for the transport of goods must have lateral protection devices. This is important because these devices help prevent accidents by avoiding other vehicles or pedestrians from getting trapped underneath the trailer in the event of a side collision. Although the provided fragments do not explicitly mention lateral protection devices, it is a commonly required safety measure for vehicles transporting goods, especially when loads may protrude or when the vehicle is of considerable size. Additionally, trailers and semi-trailers that are more than 2.10 meters wide must comply with certain safety regulations, such as the use of clearance lights, which suggests that they must also comply with other safety measures, such as lateral protection devices.
