For a safe journey:
Do not ever put the child car seat next to the driver’s seat.
Literally follow the manufacturer’s instructions. Make sure that you have correctly fastened the child safety seat to the seat belt and the child to the car seat.
Place the child’s car seat in the back seat of the car, in order to provide double safety to the child, that of the child car seat, and that of the back seat.
It has been estimated that child safety seats, when they are correctly used, decrease up to 71% the danger of child deaths below 5 years of age, up to 67% the probability of being admitted to hospital from severe injury, and up to a 50% decrease of the danger of causing minor injuries.
