Alaska law says that a driver may not transport children under 16 in a motor vehicle unless the child is properly secured according to state child passenger safety law. Children under age 4 must be properly secured in a federally approved car seat or booster car seat. For children over age 4 but under age 16, Alaska state law requires that the child be properly secured in a vehicle seat belt or federally approved car seat or booster seat, whichever is appropriate for the particular child.
