A child who is properly secured in an approved child car seat is less likely to be killed or injured in a crash than one who is not.
Children aged between four and seven years cannot travel in the front seat of a vehicle with two or more rows unless all other back seats are occupied by children younger than seven years in a child car seat.
National child restraint laws require your child to be restrained in the car as follows:
0 – 6 months
Approved rear-facing child car seat.
6 months – 4 years
Approved rear or forward-facing child car seat.
4+ years
Approved forward-facing child car seat or booster seat.
