CPST - Certified Child Passenger Safety Technician Rear-Facing Car Seat Use Questions and Answers

Question 1

According to the American Academy of Pediatrics (AAP) and NHTSA best practice recommendations, a child should remain in a rear-facing car seat until they:

Accepted Answer

Reach the highest weight or height limit allowed by the car seat manufacturer.

Answer

Both the AAP and NHTSA recommend keeping children in a rear-facing car seat for as long as possible, until they reach the maximum height or weight specified by the car seat's manufacturer. This provides the best protection for the head, neck, and spine in a crash. Age-based recommendations, like turning at age two, are no longer the primary guidance.

Question 2

A caregiver is concerned that their 18-month-old's legs are bent and touching the back of the vehicle seat while rear-facing. What is the appropriate guidance for a CPST to provide?

Accepted Answer

This is a common and acceptable situation; it does not pose a safety risk and is not an indication to turn the child forward-facing.

Answer

It is common for a rear-facing child's legs to bend and touch the vehicle seat back. This is not a safety concern and does not cause injury in a crash. Children are flexible and will find a comfortable position. The decision to transition to a forward-facing seat should be based on the manufacturer's height and weight limits, not the child's leg position.

Question 3

When positioning the harness straps for a child in a rear-facing car seat, which of the following is correct?

Accepted Answer

The straps should be positioned at or just below the child's shoulders.

Answer

For a rear-facing car seat, the harness straps must be threaded through the slots that are located at or just below the child's shoulders. This helps to keep the child from sliding upward in the seat during a frontal crash, which is the most common type of severe crash.

Question 4

Which of the following is a critical rule regarding the placement of a rear-facing car seat in a vehicle?

Accepted Answer

It must never be placed in a seating position with an active frontal airbag.

Answer

A rear-facing car seat must never be placed in front of an active frontal airbag. If the airbag were to deploy, it would strike the back of the car seat with great force, directly where the child's head is, which could result in serious injury or death. While the center rear seat is often the safest, it's not always possible or required. Installation with a seat belt or LATCH is acceptable as long as it's done correctly.

Question 5

A CPST is checking a rear-facing infant seat installation. When testing for tightness at the belt path, what is the maximum acceptable amount of movement?

Accepted Answer

Less than one inch of movement side-to-side or front-to-back.

Answer

When installed correctly, the car seat (or base) should not move more than one inch in any direction (side-to-side or front-to-back) when checked at the belt path. The test for tightness should be performed with your non-dominant hand where the seat belt or LATCH webbing passes through the car seat.
