Roof racks, on the other hand, are the framework or bars that are attached to the roof of a vehicle to support the roof box or other items being carried on the roof. They provide a secure base for attaching accessories like roof boxes, bike racks, or ski racks. Together, car roof boxes and roof racks are popular accessories for increasing a vehicle's storage capacity and versatility. **

However, in severe accidents, the roof may still collapse, posing a serious risk to the occupants inside the vehicle. **
