Final answer:
The safest seat for all children is the rear-facing seat, which is especially important for infants and toddlers, providing better support in a crash. As children grow, they transition to forward-facing and booster seats, with the recommendation that children under 13 ride in the back seat.
Step-by-step explanation:
The safest place for all children when riding in a vehicle is to be sitting and secured in the rear-facing seat, particularly for infants and toddlers. Auto safety experts recommend that children remain in a rear-facing car seat until they reach the maximum height or weight limit allowed by the car seat's manufacturer. This provides better support for the child's head, neck, and spine in the event of a collision. Once a child outgrows the rear-facing seat, they can transition to a forward-facing seat with a harness and later move to a booster seat as they continue to grow. It's also recommended that all children under the age of 13 ride in the back seat of the vehicle for maximum safety.
