4′9″ = 57 in. Enter only the boxes you have — Arizona uses required ages 5–7 while 4′9″ or shorter; exit at age 8 or taller than 4′9″.
Arizona does not legislate rear-facing vs forward-facing by age — it requires a restraint appropriate per the manufacturer's instructions. AAP/NHTSA best practice (not Arizona law): rear-facing to age 2+, then a harness, then a booster.

Plain-language summary, not legal advice.
This shows the minimum legal requirement in Arizona — not best safety practice, which is usually stricter, and not legal or safety advice. Always follow your car seat's manufacturer instructions. For the full four-stage rules, front-seat rule, and citation, see the Arizona car seat law reference, cited to A.R.S. §28-907 (last reviewed 2026-07-09).
How Arizona car seat law works
Arizona is the most lenient of these 15 states. Section 28-907 requires a child restraint only for children under 5, and a booster only for children 5–7 who are 4′9″ or shorter — so a tall or older child leaves the requirement quickly. Arizona does not legislate rear-facing by age, which means "rear-facing until 2" is AAP/NHTSA best practice here, not law. It also has no front-seat law: the statute applies to each passenger regardless of seating position, so the familiar back-seat-until-13 advice is a recommendation, not something an officer can cite. The booster exit is age 8 or 4′9″, whichever comes first, and the fine is a waivable $50.
