CPST Infant & Newborn Transportation Safety 1 — Questions and Answers
Question 1: What is the recommended car seat position for a healthy full-term newborn leaving the hospital?
- Rear-facing in a rear-facing-only or convertible seat (Correct answer)
- Forward-facing with a 5-point harness
- In an infant carrier worn by a parent
- In a rear-facing booster with a vehicle belt
Correct answer: Rear-facing in a rear-facing-only or convertible seat
All healthy full-term newborns should ride rear-facing in an appropriate rear-facing infant or convertible car seat from their very first ride home.
Question 2: Why is a semi-reclined position important for newborns in rear-facing car seats?
- To prevent the airway from becoming compromised if the head falls forward (Correct answer)
- To allow the child to sleep more comfortably on long trips
- To ensure the harness slots sit above the shoulders
- To reduce the risk of the child sliding out of the harness
Correct answer: To prevent the airway from becoming compromised if the head falls forward
Newborns lack neck muscle strength to hold their heads up, so a semi-reclined angle prevents the head from falling forward and blocking the airway.
Question 3: Which of the following is TRUE about using head inserts or head support padding in infant car seats?
- Only inserts that came with the seat or are approved by the manufacturer should be used (Correct answer)
- Any padded insert sold in baby stores is safe to add
- No head support is needed since the harness holds the head in place
- Head inserts are only needed for premature infants
Correct answer: Only inserts that came with the seat or are approved by the manufacturer should be used
Aftermarket inserts not approved by the seat's manufacturer can interfere with harness fit and crash performance; only manufacturer-provided accessories should be used.
Question 4: At what recline angle should most rear-facing infant seats be positioned to keep a newborn's airway open?
- Approximately 30 to 45 degrees from vertical, as specified by the manufacturer (Correct answer)
- Perfectly flat at 0 degrees
- Fully upright at 90 degrees from horizontal
- At whatever angle the vehicle seat naturally provides
Correct answer: Approximately 30 to 45 degrees from vertical, as specified by the manufacturer
Most manufacturers specify a recline angle of roughly 30–45 degrees from vertical for newborns to prevent head-slump and airway compromise; always follow the specific seat's manual.
Question 5: A newborn's harness straps should be routed through which harness slots in a rear-facing seat?
- The slots at or below the shoulders (Correct answer)
- The slots at or above the shoulders
- The highest available harness slots
- Whichever slots allow the most slack
Correct answer: The slots at or below the shoulders
In a rear-facing seat, harness straps must be threaded through slots at or below the child's shoulders to properly restrain a newborn in a crash.
Question 6: How should a CPST check that a rear-facing harness is snug enough on a newborn?
- Perform the pinch test — no webbing should be pinchable at the collarbone (Correct answer)
- Ensure there is one finger's width of slack at the chest clip
- Check that the harness can be pulled 2 inches from the chest
- Confirm the buckle clicks audibly when fastened
Correct answer: Perform the pinch test — no webbing should be pinchable at the collarbone
The pinch test at the collarbone confirms proper harness snugness — if you can pinch the webbing, the harness needs tightening.
