Even small items must be well secured for transportation. Never underestimate the force that even a supposedly light “load” (cell phone!) can develop in the event of an accident. ADAC studies show that unsecured loads can accelerate to 50 times their own weight in the event of a head-on collision at 50 km/h. This can be life-threatening for everyone involved. This can be life-threatening for everyone involved!
Of course, every company that transports products itself knows this in theory. The reality in estate cars is often different - the vehicle's own nets, which separate the load compartment from the passenger compartment, must be sufficient. Of course, these nets and luggage compartment covers provide protection and are better than nothing, but they are not really safe.
