Yes, you must have one for each child. Children under 3 years old must be transported by means of a suitable restraint system (baby seat). Children over 3 years old who are less than 150 cm tall and weigh less than 36 kg (that is, children under 12 years old) must use the car seat, the booster seat or the booster cushion when traveling.
Before leaving, we suggest you calculate the approximate number of kilometers you will travel during your rental. All rentals include 2,100 kilometers. If you expect to exceed this number, you can purchase an additional 500 km block at a cost of $100 or pay an additional $0.30 per kilometer upon your return.
