Indiana Child Car Seat Laws
Indiana child car seat laws require every child under age 8 to ride in a child restraint system used according to the manufacturer’s instructions. Children from age 8 up to their 16th birthday must be secured by either a child restraint or a seat belt. This guide explains what the Indiana child car seat law says, how it applies by age and size, what penalties apply, and where families can get a seat checked.
What Do Indiana Child Car Seat Laws Require?
The core rule is in Indiana Code 9-19-11-2. A driver commits a Class D infraction if a child under 8 is not properly fastened in a child restraint system according to the manufacturer’s instructions. The statute does not name a specific seat type, so the height and weight limits printed on your seat decide what is correct.
Indiana Code 9-19-11-3.6 covers older children. Anyone at least 8 but under 16 must be restrained by a child restraint system or a safety belt. The Indiana child restraint law applies in cars, trucks and SUVs, and in every seating position.
Indiana Car Seat Requirements by Age and Stage
The state law is built on age, but the Indiana State Police describe the stages by size. Together they give a clear path.
Rear-facing seat: Children ride rear-facing from birth until they outgrow the seat’s limits. Infant-only seats commonly top out between 22 and 40 pounds. The child then moves to a rear-facing convertible seat and stays rear-facing until reaching that seat’s upper weight or height limit.
Forward-facing harness seat: When a child outgrows the rear-facing limits, a forward-facing seat with a harness is the next step. State troopers encourage families to keep children in a harness until at least 65 pounds, where the seat allows it.
Booster seat: A belt-positioning booster follows the harness stage, usually from about age 4 and 40 pounds at the earliest. Because Indiana law keeps children in a restraint system until age 8, a booster is the seat most children aged 5 to 7 use. Boosters must be used with a lap and shoulder belt.
Seat belt: From age 8, the law permits a seat belt alone. Belt fit, not the birthday, should decide the timing.
When Can a Child Stop Using a Booster Seat in Indiana?
The Indiana booster seat law ends at age 8, but many children are not ready then. A child is ready for an adult belt when all five of these are true:
- The child sits all the way back against the vehicle seat.
- The knees bend naturally at the edge of the seat without slouching.
- The lap belt lies flat across the upper thighs, not the stomach.
- The shoulder belt crosses between the neck and shoulder.
- The child stays in that position for the whole trip.
This usually happens at about 4 feet 9 inches tall. The Indiana University School of Medicine Automotive Safety Program notes that some children older than 10 still benefit from a booster. Its figures from the National Digital Car Seat Check Form database show that nearly 23 percent of children move to boosters too soon and more than 89 percent move to a seat belt too soon.
Can a Child Sit in the Front Seat in Indiana?
The restraint statutes focus on how a child is secured, not on seat position. State police guidance says children 12 and under should ride in the back seat when one is available. Safety specialists at the IU School of Medicine recommend the back seat through age 13.
Penalties Under Indiana Child Car Seat Laws
A child restraint or seat belt violation is a Class D infraction. Money collected from these judgments goes into the state’s child restraint system account, which pays for seats given to families in need.
A driver cannot be found in violation if they carry a certificate from a physician, physician assistant or advanced practice registered nurse. The certificate must state that restraining the child in a child restraint system is impractical because of a physical or medical condition, and the driver must present it to the officer or court. State guidance has also noted that courts may waive the fine for a first-time offender who brings a seat to court. Confirm that with the court handling your citation, because practices vary.
Exceptions to the Indiana Car Seat Law
Certain vehicles are exempt from the child restraint rules, including school buses, taxis and medical vehicles. The usual requirements still apply to rideshare drivers. Families who use Uber or Lyft should bring their own seat.
State guidance also describes a narrow lap belt exception. If all lap and shoulder belts are already in use by other children, a child over 40 pounds may ride in a lap-only belt. A booster cannot be used safely with a lap-only belt.
Where to Get a Car Seat Checked in Indiana
Indiana has free resources that check your installation and teach you to do it correctly.
The Marion County Public Health Department runs the Safe Travel Car Seat Inspection Station at 3838 N. Rural Street, Indianapolis, IN 46205. It is open Monday through Friday from 8:00 a.m. to 5:00 p.m. Free inspections are by appointment, and the appointment line is 317.221.2045.
The IU School of Medicine Automotive Safety Program holds an annual free community car seat clinic. In 2026 it ran on Tuesday, May 19, from 4:30 p.m. to 6:30 p.m. at Ivy Tech Community College in Indianapolis, Parking Lot 9, 108 W 28th Street, with entry from West 28th Street. It was first come, first served with no appointment. Families brought the child, the seat and the vehicle. The 2024 clinic completed more than 140 inspections and gave out more than 120 car seats. Confirm the date for next year before you plan to attend.
Riley Children’s Health and Indiana University Health also offer car seat safety checks at some locations. The IU School of Medicine inspection station finder lists sites by area.
Practical Checks Before Every Trip
- Check the seat’s expiration date, recall status and crash history.
- Follow the manufacturer’s manual and your vehicle owner’s manual for installation.
- Remove bulky winter coats before buckling a child in. Place a blanket over the harness instead.
- Confirm the harness is snug at the collarbone and the chest clip sits at armpit level.
- Replace a seat after a crash, following the manufacturer’s guidance.
Indiana child car seat laws apply to all vehicles on Indiana roads, so visiting families should bring a correctly sized seat from home or arrange one before arrival. The Indiana Criminal Justice Institute Traffic Safety Division reports that 26 children were killed in Indiana traffic collisions in 2024. Correct use of the right seat is the most direct step a driver can take.
