4′9″ = 57 in. Enter only the boxes you have. South Carolina uses booster required until the child is 8 or 57″ (4′9″); reaching either lets a properly fitting adult belt be used.
Heads up: South Carolina’s rear-facing-under-2 requirement and the 57″ booster threshold took effect in 2017 (Act 61). Older summaries describing an age-6 or 40-lb cutoff are pre-2017 and outdated.

Plain-language summary, not legal advice.
This shows the minimum legal requirement in South Carolina, 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 South Carolina car seat law reference, cited to S.C. Code §56-5-6410 (last reviewed 2026-07-11).
How South Carolina car seat law works
South Carolina rewrote its child-passenger law in 2017, and any summary using an age-6 or 40-lb cutoff is quoting the repealed version. The current statute (§56-5-6410) legislates rear-facing by age: a child under 2 must ride rear-facing in the rear seat until they pass the seat’s height or weight limit. That makes South Carolina one of the states where rear-facing is real law, not just best practice. After a forward-facing harness stage, a booster is required until the child is 8 or 57″ tall, whichever comes first. Rear-seat placement is also codified here: a child under 8 rides in back where a rear seat exists. The first-offense fine reaches $150, but the court must waive it if you show proof you bought the correct seat before your court date.
