FAQ

What are the booster seat requirements in Montana?

Montana car seat laws do not specify when a child can sit in a booster seat. The law states that children six years old and younger that weigh 60 pounds or less have to ride in a child passenger restraint system that meets federal guidelines. The child passenger restraint system’s manufacturer guidelines must support the height and weight of the child. The Montana Department of Transportation recommends keeping children who have outgrown their car seats to ride in a booster seat until they are eight years old and are 4’9” tall. The booster seat should always be in the back seat.    

What are the rear-facing car seat laws in Montana?

Montana car seat laws do not explicitly state when you can switch your child to a forward-facing car seat. Follow your child restraint system’s guidelines when securing your child. Make sure that your child is the appropriate age, height, and weight to be properly secured in the child passenger restraint system.

How tall do you have to be to sit in the front seat in Montana?

Montana law does not state when a child can ride in the front seat. The Montana Department of Transportation urges parents to keep their children in the back seat until they are at least 13 years old.
