Montana’s New Car Seat Laws Take Effect October 1

Starting October 1, Montana families will notice some major updates to the state’s car seat law. House Bill 586 officially goes into effect, bringing our child passenger safety rules up to federal standards. The good news? The new law makes it much clearer how kids should be buckled in at every age and stage.

New Law Brings Clarity and Safety to Montana’s Car Seat Rules

Up until now, Montana’s car seat requirements left a lot of room for interpretation. By aligning with federal guidelines, the new law gives parents more specific directions so there’s less guesswork and more peace of mind. After all, the goal is simple: to keep Montana’s kids safe on the road.

New Rule: Babies and Toddlers Must Ride Rear Facing

If you have a baby or toddler under the age of two, they must now be in a rear facing car seat with an internal harness. This position gives the best head, neck, and spine protection in the event of a crash.

Car Seat Guidelines for Montana Kids Ages Two to Four

Between ages two and four, children can ride in either a rear-facing seat (if they still fit) or a forward facing car seat with a harness. If your little one hasn’t maxed out the height or weight limits for their rear facing seat, experts say to keep them rear facing as long as possible, it’s the safest option.

Car Seat and Booster Rules for Kids Ages Four to Eight

Once kids turn four, they should move into a forward facing car seat or a booster seat, secured with the vehicle’s lap shoulder belt. The booster makes sure the seat belt fits correctly across their chest and lap instead of riding up where it could cause injury.

When Montana Kids Can Safely Switch to Adult Seat Belts

At age nine, or sooner if they outgrow the height or weight limits of their booster seat, kids can move to a regular adult seat belt. A good test: if your child can sit with their back against the seat, knees bent at the edge, and the belt fits snugly across their shoulder and lap, they’re ready.

How to Check If Your Child Has Outgrown Their Seat

If you’re not sure whether your child’s current seat still fits under the new guidelines, now’s the time to double check. Look at the height and weight limits on your car seat and booster, and make sure your child hasn’t outgrown them. If they have, it’s time to size up.
