Montana was the state where I watched a major law change happen in real time. In October 2025, HB 586 took effect and completely rewrote Montana’s car seat requirements — adding rear-facing until age 2, forward-facing with harness until age 4, and boosters until age 8. Before this, Montana’s law only covered kids under 6 and under 60 pounds, which was years behind the science. The new law finally caught up.
Montana recorded 203 traffic fatalities in 2024, with early 2025 numbers trending slightly above the same period in 2024. For a state with just over a million people, that’s a disproportionately high fatality rate — consistently above the national average. Car seats reduce fatal injury risk by 71% for infants and 54% for toddlers.
This guide covers Montana’s updated car seat laws, real programs that provide free or low-cost seats, and the fastest steps to get one for your child today.

Montana car seat laws (updated October 2025)
Montana’s HB 586 took effect October 1, 2025, bringing the state in line with modern safety science:
- Under age 2: Must ride in a rear-facing car seat that complies with federal safety standards.
- Ages 2 through 3: Must be in a rear-facing or forward-facing car seat with an internal harness.
- Ages 4 through 8: Must use a forward-facing car seat or booster seat.
- Age 9 and older (or outgrown booster height/weight limits): Must be secured with a standard seat belt.
The fine for violations is 0. This is a significant upgrade from the old law, which only required car seats for children under 6 and under 60 pounds.

Montana-specific programs worth knowing about
SafeSeat for Baby — Healthy Mothers, Healthy Babies (statewide) — This is Montana’s primary free car seat program. When a family’s need is recognized, a local health department or early childhood specialist refers them to the program. A certified Car Seat Technician then provides the seat, installs it, and trains the parent on proper use. Processing takes 1-2 weeks. Visit hmhb-mt.org for details.
Montana Department of Transportation — Vision Zero CPS Events — MDT coordinates child passenger safety events and fitting stations across the state. These events provide free car seat inspections and sometimes distribute seats. Visit mdt.mt.gov CPS events for upcoming dates and locations.

A quick warning about secondhand seats
If someone offers you a used car seat, proceed with caution. Only accept one if you can verify all four of these:
- It has never been in a crash — even a minor one
- It hasn’t expired (check the label — most seats expire 6 to 10 years after manufacture)
- There are no cracks, missing parts, or frayed harness straps
- It hasn’t been recalled by NHTSA
If you can’t confirm all four, it’s not worth the risk. A brand-new Cosco Mighty Fit 65 runs about and meets every federal safety standard. The Evenflo Tribute is another solid option around .
Don’t do this alone
Montana’s new law is a big step forward, and the SafeSeat for Baby program ensures that cost doesn’t have to be a barrier to compliance. With the state’s fatality rate consistently above the national average — especially on rural highways — proper child restraint matters here more than in most places. If you’re new to car seats entirely, start with our car seat safety basics guide to understand what type of seat your child needs right now.
