The load on the roof rack must be arranged primarily by ensuring it does not affect the stability of the vehicle, since incorrect distribution or excessive weight can compromise the balance and safety of driving. Although covering it with a tarpaulin is advisable to prevent it from shifting, the stability of the car is the fundamental consideration. The rear lighting must never be hidden, as it is essential for visibility and road safety.
