Indiana Car Seat Laws (2026): Ages, Exemptions & Penalties

Indiana requires every child younger than 8 to ride in a child restraint system installed and used according to the manufacturer's instructions, and every child from 8 up to 16 to be restrained by a child restraint system or a seat belt, under IC 9-19-11-2 and IC 9-19-11-3.6. Unlike states that write separate rear-facing, forward-facing, and booster stages into the statute, Indiana's law leaves seat type and orientation to the restraint manufacturer's own instructions. This page reflects the statute's text as of September 2026.

Jurisdiction scope: This article covers car seat and child-restraint law in the state of Indiana only. It does not address any other state. For other states, see the car seat laws hub.

Under 8: the undifferentiated child restraint duty

IC 9-19-11-2(a) makes it a Class D infraction to operate a vehicle with a child under 8 who is "not properly fastened and restrained according to the child restraint system manufacturer's instructions by a child restraint system." Indiana's statute doesn't write its own rear-facing, forward-facing, or booster thresholds the way some states do; it points instead to whatever the restraint's own manufacturer instructions require for the child's age, weight, and height. In practice, that means the seat's labeling, not a separate Indiana age-weight-height table, decides when a child moves from one seat orientation to the next.

Ages 8 through 15: child restraint system or seat belt

Once a child reaches 8, IC 9-19-11-3.6(a) takes over and requires the child to be "properly fastened and restrained according to the child restraint system manufacturer's instructions by a: (A) child restraint system; or (B) safety belt," through age 15. A family can keep an older child in a booster or other child restraint system past age 8, or move to a standard safety belt, as long as one of the two is used correctly. The duty applies only in a vehicle "equipped with a safety belt meeting the standards stated in the Federal Motor Vehicle Safety Standard Number 208 (49 CFR 571.208)."

The lap belt exception for a child over 40 pounds

IC 9-19-11-3.7 carves out a narrower alternative that applies "notwithstanding sections 2 and 3.6 of this chapter." A driver may restrain a child who weighs more than 40 pounds with a lap safety belt alone, instead of a child restraint system or the child restraint-system-plus-belt combination those two sections otherwise require, if either: the vehicle is not equipped with lap-and-shoulder safety belts at all, or every lap-and-shoulder safety belt in the vehicle other than the operator's seat and the front passenger seat is already being used to properly restrain another child under 16. The exception reaches both the under-8 restraint duty and the 8-to-15 duty; it does not apply to a child who weighs 40 pounds or less.

The medical exemption

A person is not in violation of the under-8 restraint duty if they carry "a certificate from a physician, physician's assistant, or advanced practice registered nurse stating that it would be impractical to require that a child be fastened and restrained by a child restraint system because of: (1) a physical condition, including physical deformity; or (2) a medical condition." The certificate has to be in hand; the exemption applies only to the under-8 child restraint system requirement in section 2, not the 8-to-15 belt duty.

Exemptions from Indiana's child restraint law

IC 9-19-11-1 lists the vehicles and situations this chapter does not reach at all:

car seat - seatbelt positioning

  • A school bus, a special purpose bus, a taxicab, or a medical services vehicle.
  • A bus, motorcycle, motor-driven cycle, passenger motor vehicle, or truck that was originally manufactured without a safety belt as standard equipment at each designated seating position, before Indiana required safety belts meeting Federal Motor Vehicle Safety Standard Number 208 (49 CFR 571.208).
  • A government-owned or leased vehicle used in the performance of official law enforcement duties, a vehicle being used in an emergency, and funeral equipment used in the operation of funeral services.
  • A vehicle used by a TNC driver, such as a rideshare driver, while providing a prearranged ride to a TNC rider, as defined in IC 8-2.1-17-13.5. This exemption applies only during that prearranged ride, not to a TNC driver's personal use of the same vehicle.

That list covers vehicles and drivers the chapter never reaches at all. It is separate from the lap-belt-only exception in IC 9-19-11-3.7 above, which still applies the chapter's restraint duty but lets a child over 40 pounds satisfy it with a lap belt alone in narrower circumstances, and from the physician/PA/APRN medical exemption to the under-8 duty described next.

Penalty for violating Indiana's car seat law

Both the under-8 restraint duty and the 8-to-15 belt duty are Class D infractions under IC 9-19-11-2 and IC 9-19-11-3.6. A Class D infraction carries a judgment of up to $25 under IC 34-28-5-4(d), and a defendant found to have committed a Class D infraction is not liable for separate court costs under IC 34-28-5-5(b).

Indiana also gives a first offender a way to avoid that judgment entirely. Under IC 9-19-11-5, if a court in a proceeding to enforce the under-8 duty finds that the person violated the chapter but already possesses or has since acquired a child restraint system, the court still enters judgment, but the person is not liable for any costs or monetary judgment if they have no previous judgments of violation of the chapter. Under IC 9-19-11-6, if the person does not yet possess or have a restraint system, the court instead orders the person to provide proof of possession or acquisition within 30 days; a first offender who complies is likewise not liable for any costs or monetary judgment. This relief runs to proceedings enforcing the under-8 restraint duty in section 2 and to first offenders only; it is not written into IC 9-19-11-3.6 itself.

Leaving a child unattended

Indiana does not have a statute that specifically addresses leaving a child alone in a vehicle. A caregiver who does so can still face liability under Indiana's general neglect-of-a-dependent statute, IC 35-46-1-4, which makes it a Level 6 felony for a person having the care of a dependent to knowingly or intentionally place the dependent in a situation that endangers the dependent's life or health, among other prohibited acts. The offense escalates to a Level 5, Level 3, or Level 1 felony depending on whether the act results in bodily injury, serious bodily injury, or death or catastrophic injury to a dependent under 14. This is a general child-endangerment law, not a car-seat-specific or vehicle-specific statute, but it is the real legal exposure a caregiver faces for leaving a child unattended in a vehicle in Indiana.

Federal guidance vs. Indiana law

The federal standard governing child car seats as products, FMVSS 213 (49 CFR 571.213), sets crash-test and performance requirements a seat must meet to be sold; it creates no duty on a parent or driver to use the seat a particular way; that is Indiana's own statute's job. The National Highway Traffic Safety Administration and the American Academy of Pediatrics separately recommend keeping a child rear-facing as long as the seat's own height and weight limits allow, then moving through a forward-facing harness, a booster, and finally a seat belt. That recommendation is safety guidance layered on top of Indiana's own legal floor, not a separate legal requirement; a newer federal side-impact standard for car seats themselves, FMVSS 213a/213b, becomes mandatory for manufacturers on December 5, 2026, and changes what a seat must be built to withstand, not what Indiana law requires a driver to do.

Frequently Asked Questions

Until what age does a child need a car seat in Indiana?

A child under 8 must be restrained by a child restraint system used according to the manufacturer's instructions, under IC 9-19-11-2. From 8 through 15, a child restraint system or a seat belt satisfies IC 9-19-11-3.6.

Does Indiana have a medical exemption from the car seat law?

Yes. A person is not in violation of the under-8 restraint duty if they carry a certificate from a physician, physician's assistant, or advanced practice registered nurse stating that a child restraint system is impractical because of a physical or medical condition.

Are taxis and rideshare vehicles exempt from Indiana's car seat law?

Yes for both, with a limit on the rideshare exemption. Taxicabs are fully exempt under IC 9-19-11-1. Transportation network company drivers, such as rideshare drivers, are exempt only while providing a prearranged ride to a TNC rider.

What is the penalty for a car seat violation in Indiana?

Both the under-8 restraint duty and the 8-to-15 belt duty are Class D infractions, carrying a judgment of up to $25 under IC 34-28-5-4(d) with no separate court costs. In a proceeding to enforce the under-8 duty, a first offender who already owns, or provides proof within 30 days of acquiring, a compliant child restraint system is not liable for any costs or monetary judgment at all, under IC 9-19-11-5 and IC 9-19-11-6.

What happens if you leave a young child alone in a car in Indiana?

Indiana has no statute specific to leaving a child unattended in a vehicle. A caregiver can still be prosecuted under the general neglect-of-a-dependent statute, IC 35-46-1-4, a felony that can escalate based on the harm caused.

Rebuilt this page's Indiana car-seat requirements: Indiana Code 9-19-11-2 and 9-19-11-3.6 set no state age or weight cutoffs for rear-facing, forward-facing, or booster seats (they require restraint per the seat manufacturer's own instructions for children under 8, and a restraint system or seat belt for ages 8-15); the previous 'under 1 year/20 lb' and '30 lb booster' figures were not in the statute and have been replaced with the actual statutory standard plus NHTSA/AAP safety guidance clearly labeled as guidance rather than law.
