Indiana Car Seat Laws: Requirements by Age, Seat, and Belt

Indiana car seat laws require every child under eight to ride in a federally approved child restraint system, and every child from eight through fifteen to be secured in either a child restraint or a vehicle seat belt.1Indiana General Assembly. Indiana Code 9-19-11-2 – Child Less Than Eight Years of Age; Child Restraint System; Penalty; Medical Exceptions; Child Restraint System Account2Indiana General Assembly. Indiana Code 9-19-11-3.6 – Safety Belt Standards; Child Between Eight and 16 Years of Age; Child Restraint System or Safety Belt The driver of the vehicle is the one on the hook if a young passenger is not properly restrained, not the parent riding along. The statute itself does not list ages or weights for rear-facing, forward-facing, or booster use. Instead, it ties compliance to the seat manufacturer’s printed instructions, which makes those instructions legally binding in Indiana.

The Rule for Children Under Eight

Indiana Code 9-19-11-2 says a driver commits a Class D infraction if a child under eight is not “properly fastened and restrained according to the child restraint system manufacturer’s instructions.”1Indiana General Assembly. Indiana Code 9-19-11-2 – Child Less Than Eight Years of Age; Child Restraint System; Penalty; Medical Exceptions; Child Restraint System Account The restraint must be federally approved, meaning it meets Federal Motor Vehicle Safety Standard 213.3National Highway Traffic Safety Administration.

Because the law defers to the manufacturer, the right type of seat at any given moment is whatever the label on your seat says it should be for your child’s current height and weight. If the label says rear-facing to 40 pounds and your child weighs 28 pounds, keeping that child rear-facing is your legal obligation in Indiana, not just a safety recommendation.

Rear-Facing Infants and Toddlers

Nearly every infant seat on the market is designed for rear-facing use only, so in practice all infants in Indiana ride rear-facing. Rear-facing-only seats generally accommodate babies up to around 30 to 35 pounds. Convertible seats often allow rear-facing use to 40 or even 50 pounds.

NHTSA recommends keeping children rear-facing as long as the seat allows, not just until some minimum age.3National Highway Traffic Safety Administration. Car Seat and Booster Seat Safety, Ratings, Guidelines The American Academy of Pediatrics notes that most convertible seats allow rear-facing for two years or more.4HealthyChildren.org. Car Seats: Information for Families Rear-facing supports the head, neck, and spine far better in a crash, and turning a toddler forward at the earliest possible moment is one of the most common mistakes parents make.

Forward-Facing With a Harness

Once a child outgrows the height or weight limits printed on the rear-facing seat, the next stage is a forward-facing seat with an internal harness. Most harnessed seats are rated for children from roughly 22 pounds up to 65 or even 90 pounds, depending on the model.

The seat is secured to the vehicle using either the lower anchors with the top tether or the vehicle’s seat belt, and the seat’s manual specifies which to use and at what child weight to switch methods. The top tether is critical for a forward-facing seat because it limits how far the child’s head moves forward in a crash.

Booster Seats

When a child outgrows the harness but is still under eight, a booster seat is required. Indiana’s statute explicitly includes belt-positioning boosters as a type of federally approved child restraint.5Indiana Criminal Justice Institute. Children A booster raises the child so the lap belt sits across the upper thighs and the shoulder belt crosses the chest and shoulder rather than the neck or face.

The seat belt fit test matters more than hitting the age of eight. NHTSA advises keeping a child in a booster until the lap belt sits snugly across the upper thighs, not the stomach, and the shoulder belt lies across the shoulder and chest without crossing the neck.3National Highway Traffic Safety Administration. Car Seat and Booster Seat Safety, Ratings, Guidelines Many children do not pass this test until age 10 or 12. Indiana sets a floor, not a ceiling.

Seat Belt Rules for Ages Eight Through Fifteen

Indiana Code 9-19-11-3.6 covers children who are at least eight but younger than sixteen. They must be properly fastened in either a child restraint system or a vehicle safety belt, in every seating position in the vehicle.2Indiana General Assembly. Indiana Code 9-19-11-3.6 – Safety Belt Standards; Child Between Eight and 16 Years of Age; Child Restraint System or Safety Belt The driver commits a Class D infraction if a child in this range rides unbuckled.

The law gives parents a choice between a restraint and a seat belt for this age group, so putting a small eight-year-old back in a booster is fully legal and often the safer call if the vehicle belt still rides across the neck.

Front Seat and Airbags

Indiana’s statute does not bar children from sitting in the front seat, but federal guidance is firm about it. NHTSA recommends that all children under 13 ride in the back seat to avoid injury from passenger-side airbag deployment.6National Highway Traffic Safety Administration. Air Bags A rear-facing seat should never be placed in front of an active airbag; the force of deployment can cause fatal injuries to an infant.

NHTSA authorizes airbag on-off switches only in narrow circumstances, such as when the vehicle has no rear seat, when a child under 13 must ride in front for medical monitoring, or when the driver is shorter than four feet six inches.6National Highway Traffic Safety Administration. Air Bags

Which Vehicles Are Exempt

Indiana’s child restraint chapter does not apply to school buses, taxicabs, ambulances, or public passenger buses.1Indiana General Assembly. Indiana Code 9-19-11-2 – Child Less Than Eight Years of Age; Child Restraint System; Penalty; Medical Exceptions; Child Restraint System Account Motorcycles fall outside the chapter and operate under separate safety rules.

Rideshare vehicles like Uber and Lyft are not exempt. They are private passenger vehicles, and the driver can be cited if a child rides unrestrained. Both companies place responsibility for providing a car seat on the rider.7Uber. Uber Community Guidelines – Following the Law You need to bring your own seat if you’re traveling with a young child, and some drivers will cancel the trip rather than risk the citation.

Medical Exemption

A driver is not liable under the car seat statute if the child has a physical or medical condition that makes a standard restraint impractical or dangerous. To claim this exemption, the driver must carry a written certificate from a physician, physician’s assistant, or advanced practice registered nurse describing the condition, and must present it to the officer at the stop or to the court afterward.1Indiana General Assembly. Indiana Code 9-19-11-2 – Child Less Than Eight Years of Age; Child Restraint System; Penalty; Medical Exceptions; Child Restraint System Account

This is a narrow exemption. A general note saying car seats are uncomfortable for a child will not satisfy it. The certificate needs to address a specific physical deformity or medical condition, and should stay in the vehicle.

Penalties for a Violation

A car seat violation is a Class D infraction with a maximum fine of $25, though court costs and administrative fees added on top can push the actual bill significantly higher.8Indiana General Assembly. Indiana Code 34-28-5-4 The BMV assesses points on a driver’s record for moving violation convictions, and points can affect insurance rates.9Indiana Bureau of Motor Vehicles. Driver Record Points

Indiana offers first-time offenders a way out of the money part. If the court finds you violated the statute but you have since acquired a child restraint and have no prior judgments for the same violation, you are not liable for any fine or court costs.10Indiana University Automotive Safety Program. Indiana Child Passenger Law A second violation carries the full fine and a permanent entry on your record.

There is a civil dimension too. If a child is injured in a crash while improperly restrained, violation of the safety statute can be used as evidence of negligence in a lawsuit. It does not automatically establish liability, but it changes the shape of settlement negotiations.

Free Car Seat Inspections

Indiana operates roughly 103 child safety seat inspection stations across the state, managed by the Indiana Criminal Justice Institute. A certified child passenger safety technician will check your installation at no charge.11Indiana Criminal Justice Institute. Child Safety Seat Inspection Stations Most installation mistakes are invisible to an untrained eye. A harness routed through the wrong slot or an anchor belt that is not locked can make a correctly chosen seat almost useless in a crash. An appointment takes about 20 minutes.
