Montana Car Seat Laws

Children under the age of six and weighing less than 60 pounds must be in an appropriate safety restraint for their height and weight.  Montana law requires parents to use the manufacturer’s guidelines for height and weight restrictions when choosing a safety seat for their child.

  • Birth to 2yrs of age: Rear-Facing Car Seat. Children can start off in an infant-only rear facing car seat and move up to a convertible, 3-in-1 or other rear-facing car seat until they reach the height and weight limits of the car seat which is usually just after age 2.
  • Age 2-4 or 5:  After the child has outgrown the rear-facing car seat, they move on to a forward facing car seat. Forward facing car seats include forward-facing only, convertible, 3-in-1 and Combination car seats. Children should remain in a forward facing car seat until they have outgrown the manufacturer’s guidelines for height and weight restrictions.
  • About age 5-8: Once children have outgrown their forward facing seat, they can move on to a booster seat. Children should remain in a booster seat until they are at least 4’9. This height usually occurs when the child is 8 – 12 years old. NEVER use only a lap belt with a booster seat.
  • Children should ride in the back of a car until they are 13 years old.
