Indiana does not legislate rear-facing vs forward-facing by age; it requires a restraint appropriate per the manufacturer's instructions. Best practice from AAP (the pediatricians' association) and NHTSA (the federal highway-safety agency), not Indiana law: rear-facing to age 2+, then a harness, then a booster.

How Indiana car seat law works
Indiana’s child restraint rule is short and age-based: a child under 8 must be in a child restraint used according to the seat maker’s instructions, and from age 8 a seat belt (or a restraint) is legal through age 15. There is no 4′9″ line and no weight number in the statute, so age 8 is the clean trigger. Because the law defers sizing to the manufacturer and says nothing about orientation, "rear-facing until 2" is best practice in Indiana, echoed by the Indiana State Police, but it is not the statute. The penalty is modest: a Class D infraction with a $25 maximum judgment, though court costs are separate and usually larger. A useful quirk is that a first-time offender can wipe out both the fine and the costs by buying and installing a proper restraint within 30 days of conviction. Indiana sets no back-seat law, so front-seat placement is a recommendation here.
