Check your child's stage in South Carolina
Enter age, height, and weight. We show the South Carolina law separately from best practice.
4′9″ = 57 in. Enter only the boxes you have; this state uses booster required until the child is 8 or 57″ (4′9″); reaching either lets a properly fitting adult belt be used.

The four stages in South Carolina
Each rung is tagged Law or best practice.
A child under 2 must be secured rear-facing in a rear passenger seat, kept rear-facing until the child passes the seat manufacturer’s height or weight limit.
A child at least 2, or a child who has outgrown rear-facing, must be secured in a forward-facing seat with a harness in the rear seat until the child outgrows the manufacturer’s height or weight limit. In practice this runs to about age 4.
A child at least 4 who has outgrown the forward-facing harness must ride in a belt-positioning booster in the rear seat, used with both lap and shoulder belts, until the child is at least 8 years old or at least 57″ tall.
Exit rule: booster required until the child is 8 or 57″ (4′9″); reaching either lets a properly fitting adult belt be used. The adult belt must fit — lap low across the hips, shoulder belt across the chest.
Front seat, the fine & the source
Seating rule, the exact booster logic, and any recent change.
A child under 8 must ride in a rear seat where the vehicle has one. The front is allowed only if there is no rear seat, or every rear position is already used by other restrained children under 8. This is law (§56-5-6410), not a recommendation.
| Booster exit logic | Age 8 or 4′9″ — whichever first |
| Seat belt OK | At age 8 or 57″, once the adult belt fits correctly across the thighs and chest |
| First-offense fine | Up to $150 A first offense carries a fine of up to $150 with no license points. The court must waive the fine if the driver shows proof of obtaining the correct restraint before the court date. |
| Statute | S.C. Code §56-5-6410 |
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 Older summaries describing an age-6 or 40-lb cutoff are pre-2017 and outdated.
What South Carolina parents get wrong
South Carolina rewrote its child-passenger law in 2017, and any summary using an age-6 or 40-lb cutoff is quoting the repealed version.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.
Common questions
When can a child stop using a booster in South Carolina?
Once the child is at least 8 years old or at least 57″ (4′9″) tall, and the adult belt fits correctly. Reaching either the age or the height lets the child move out of the booster.
Does South Carolina require rear-facing car seats by age?
Yes. A child under 2 must ride rear-facing in the rear seat, kept rear-facing until they pass the seat manufacturer’s height or weight limit. This is South Carolina law, not just a recommendation.
Do children have to ride in the back seat in South Carolina?
Yes, for children under 8, where the vehicle has a rear seat. The front is allowed only if there is no rear seat, or all rear positions are already taken by other restrained children under 8.
What is the fine for a car-seat violation in South Carolina?
Up to $150 for a first offense, with no license points. The court is required to waive the fine if you show proof you obtained the correct child restraint before your court date.
