The law names ages — the seat's specs decide the switch
Every threshold above meets a spec question: is your child still within the seat's own height/weight limits for that mode? That's published manufacturer data, and it's what this site organizes:
- Keeping a toddler rear-facing longer → extended rear-facing seats (higher rear-facing limits).
- Moving from harness to booster → booster seats, incl. narrow boosters for 3-across.
- One seat across the whole journey → all-in-one (4-in-1) seats.
- Not sure a seat works in your car → how to check fit.
FAQ
What is the car seat law in Indiana?
Children 7 years and younger must ride in a child restraint. (As published in the IIHS state law table, retrieved 2026-07-16 — a summary, not legal advice.)
When can a child use just a seat belt in Indiana?
Ages 8 through 15 must use a seat belt. Best practice is to keep using a booster until the adult belt fits properly — lap flat on the thighs, shoulder belt across the chest — regardless of the legal minimum.
Does Indiana require children to ride in the back seat?
Indiana law states no preference for the rear seat. That is the legal position, not the safety one: NHTSA recommends all children under 13 ride in the back seat, and a rear-facing seat must never go in front of an active passenger airbag.
Is the Indiana law the same as best practice?
No — the law is the legal minimum. NHTSA recommends keeping children in each stage (rear-facing, forward-facing harness, booster) up to the seat's own height and weight limits, which usually lasts longer than the law requires.
