Montana Booster Seat Law


There’s no exact booster seat law in the state of Montana. The law says that all kids below the age of 6 have to be in a car seat which would mean that above the age of 6, no booster seat is needed.

However, the latest safety recommendations advise keeping kids in a car seat until the age of 8 or when they reach 57 inches in height.


Montana Rear-facing Car Seat Law

Since the Montana car seat laws are a blanket one, we have to use some logic to figure out what to do with a rear-facing car seat.

There’s nothing defined for rear-facing seats, so we must default to the car seat manufacturer’s recommendations. This means that we should keep our kids rear-facing until they have outgrown the car seat.

It’s suggested to keep kids rear-facing until the age of 1 or even 2. Keep in mind that the longer you can do rear-facing, the safer it is for them.


Montana Forward-facing Car Seat Law

Again we have to look at the manufacturer’s recommendations. Typically forward-facing car seats are for the 2-4 age range.

As soon as your child has outgrown the rear-facing car seat, you can upgrade to the forward-facing one.


Montana Taxi Car Seat Law

I didn’t find any laws about taxis being exempt from the car seat law. This means that you will need a car seat when traveling with your child.

If this is the case, you can bring your own car seat or have it arranged ahead of time.
