Which of the following is NOT a recommended action when securing a child in a vehicle?

Using an adult seat belt for securing a child is not recommended for younger children who require specialized restraints such as car seats or booster seats. Young children are not adequately protected by adult seat belts because these belts are designed for the average adult's size and weight. For infants and toddlers, a rear-facing child seat is considered the safest mode of travel, as it supports the child’s head, neck, and spine in the event of a collision. Additionally, once children outgrow rear-facing seats, the use of a properly installed booster seat is essential to ensure that adult seat belts fit correctly across their body, providing adequate protection. Checking the harness for tightness ensures that the child is securely fastened and helps prevent injury during sudden stops or accidents. By using an adult seat belt for a young child, the risk of severe injury can increase significantly in the event of a crash.
