Car seat laws by state (2026)
Every state draws the lines differently — when rear-facing is required, when a booster is enough, when a seat belt alone is legal. Here is all 50 states + DC in one place, displayed from the IIHS state law table.
⚖️ Plain-language summary — not legal advice. These provisions are displayed from the IIHS state law table (retrieved 2026-07-16). Laws change and have exceptions — verify against the table or your state's statute before relying on them. And the law is a minimum: NHTSA's guidance is to keep a child in each stage up to the seat's own height/weight limits, which usually lasts longer than the law requires.

Does your state require the back seat?
21 of 51 jurisdictions put a rear-seat requirement in the law; the other 30 state no preference. That split is about statutes, not safety — NHTSA recommends every child under 13 ride in the back seat regardless of what the local law requires, and a rear-facing seat should never be placed in front of an active passenger airbag.
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.
