Children in cars must ride in a rear-facing infant seat until they are...?
- One year old and 7 kg
- Over one year old and 9 kg
- Over one year old and 20 kg
- One year old and 9 kg ✓
Answer: D. One year old and 9 kg
Children must ride in a rear-facing infant seat from birth until at least one year old and 9 kg (20 lbs).
Why this is the answer
The handbook sets the rear-facing stage at birth through at least one year of age and 9 kg (20 lbs). That is the point where a child can move to a forward-facing seat with a tether, which the handbook says is for children over one year and over 9 kg. Rear-facing is the first stage, so the seat is used until that one-year, 9 kg mark, and the handbook also suggests keeping the child rear-facing as long as the seat allows.
Why the other answers are wrong
- A. One year old and 7 kg — The weight is wrong — the handbook gives 9 kg (20 lbs) as the rear-facing stage limit, not 7 kg.
- B. Over one year old and 9 kg — That describes the forward-facing stage with a tether, not the point at which the rear-facing infant seat is outgrown.
- C. Over one year old and 20 kg — 20 kg does not match the handbook; the forward-facing stage it lists runs up to at least 18 kg (40 lbs), so this weight is not tied to the infant seat at all.
Remember it
Picture the two stages side by side: the infant seat ends at one year and 9 kg, and the forward-facing tether seat begins just past that line.
