Hawaii was the state that surprised me with how few dedicated free car seat programs exist for a place with such strict laws. The state updated its child restraint law in 2022 to require boosters through age 10 — one of the strictest age cutoffs in the country — but the infrastructure for helping families afford seats hasn’t kept pace. When I called around, most leads pointed to a single phone number (808-527-2588) for car seat checks, and the Keiki Injury Prevention Coalition for safety events. The good news: Hawaii offers a tax credit for car seat purchases, which is unique among states.
Hawaii recorded 102 traffic fatalities in 2024, a 10% increase from 93 in 2023. A properly used car seat reduces fatal injury risk by up to 71% for infants and 54% for toddlers. With Hawaii’s high cost of living, even a car seat can strain a family’s budget — and the law now requires one through age 10.
This guide covers every free car seat resource I’ve found in Hawaii, the state’s updated laws, and how to get professional installation help.

Hawaii car seat laws (updated 2022)
Hawaii updated its child restraint law in June 2022 (Act 122), aligning with American Academy of Pediatrics recommendations. Here’s what’s required:
- Rear-facing seat: Required for children under age 2. Must use a rear-facing seat with a harness.
- Forward-facing seat with harness: Children ages 2-3 can use a rear-facing or forward-facing seat with a harness.
- Booster seat: Required for children ages 4-9 unless the child is over 4 feet 9 inches tall. This is one of the strictest age requirements in the country.
- Seat belt: Children who have outgrown their booster (over 4’9″ or age 10+) must use a seat belt.
- Back seat: Safety experts recommend children ride in the back seat until age 13, though Hawaii law doesn’t set a strict minimum front-seat age.
Violations carry fines plus a mandatory child passenger safety class. Hawaii also offers a unique state tax credit for purchasing a child safety seat or booster. For help choosing the right seat type, see our best-rated convertible car seats guide or our safest car seat brands comparison.
Hawaii-specific programs worth knowing about
Hawaii has fewer dedicated free car seat programs than most states, but here’s what I’ve been able to verify:
- Hawaii Department of Transportation — Child Passenger Safety — Maintains safety seat inspection stations across the islands and hosts free car seat check events, especially during Child Passenger Safety Week each September. Check their event calendar for upcoming dates.
- Keiki Injury Prevention Coalition (KIPC) — The primary car seat safety organization in Hawaii. Coordinates free car seat checks and education events. Visit kipchawaii.org or call 808-527-2588 to schedule a free car seat check appointment.
- Caterkids — Hawaii-based nonprofit that provides free car seats to families in need and accepts donations of gently used seats. They verify all donated seats are safe and not expired before redistributing.
- Hawaii WIC program — While not a direct car seat provider, WIC offices can connect families to local programs and resources for obtaining free or low-cost seats.
- Local fire departments and police departments — Many offer free car seat installation checks. Call your nearest station to ask about availability.
- state tax credit — Hawaii residents who purchase a child safety seat or booster can claim a tax credit on their state income tax return. This won’t cover the full cost but helps offset it.
Important note: Program availability in Hawaii can be limited due to the islands’ small population and geographic isolation. Call 211 for the most current listings, or check our main guide to getting free car seats for national programs that serve Hawaii families.

A quick warning about secondhand seats
If a secondhand seat is your only option, check these four things before using it: (1) the expiration date — car seats expire 6-10 years after manufacture, stamped on the bottom or back; (2) crash history — never use a seat that’s been in any crash; (3) recalls — check NHTSA’s recall database; and (4) all original parts including harness, chest clip, and labels. If it fails any of these checks, see our guide on what to do with old car seats. And if budget is the main barrier, seats like the Cosco Mighty Fit 65 (under ) and Evenflo Tribute (under ) pass the exact same federal crash tests as seats costing 0+. Don’t forget to claim your Hawaii tax credit after purchasing.
Don’t do this alone
Hawaii’s booster seat law now extends through age 10, which means more families need seats for longer. Traffic fatalities in Hawaii jumped 10% in 2024, and while the islands may feel safer than mainland highways, crashes happen everywhere. Start with KIPC (808-527-2588), then Caterkids, then your local fire department. And once you have a seat, our car seat safety basics guide will walk you through getting it installed correctly — because the right seat only works if it’s used right.
