Indiana Car Seat Laws for 2026: What the Law Requires at Every Age

Last updated October 21, 2026

Indiana law requires every child under 8 to ride in a child restraint system, such as a car seat or booster seat, used according to the seat manufacturer’s instructions (IC 9-19-11-2). Children ages 8 through 15 must be secured by a child restraint or a seat belt in every seating position (IC 9-19-11-3.6). The core requirements have not changed for 2026.

Vaughn A. Wamsley Personal Injury represents Indiana families after crashes from our offices in Carmel and Indianapolis, and car seat questions come up in many of those cases. This guide covers what the statute actually says, where safety recommendations go further than the law, and what to do if your child was in a car seat during a crash.

Indiana Car Seat Requirements by Age and Stage

The statute itself is short. It sets an age line (under 8) and requires the restraint to be used the way the manufacturer says. The rear-facing, forward-facing, and booster stages come from each seat’s height and weight limits and from national safety guidance. The table below separates what the law requires from what safety agencies recommend.

What Indiana Code 9-19-11 Says

Indiana’s child passenger law is in Indiana Code 9-19-11. These are the sections parents ask about most:

• Children under 8 (IC 9-19-11-2). A driver with a child under 8 in the vehicle must make sure the child is properly fastened and restrained in a child restraint system according to the manufacturer’s instructions.
• Children 8 through 15 (IC 9-19-11-3.6). A child who is at least 8 but under 16 must be properly restrained by a child restraint system or a seat belt.
• Lap-belt exception (IC 9-19-11-3.7). A child who weighs more than 40 pounds may ride with only a lap belt when the vehicle is not equipped with lap-and-shoulder belts, or when those belts are already in use by other children. A booster cannot be used safely with a lap-only belt.
• Medical exemption (IC 9-19-11-2). The requirement does not apply when a physician, physician assistant, or advanced practice registered nurse certifies that restraining the child is impractical because of a physical or medical condition, and the certificate is presented.
• Exempt vehicles (IC 9-19-11-1). The chapter does not apply to school buses, taxicabs, ambulances, public passenger buses, motorcycles, antique vehicles, emergency and law enforcement vehicles, and certain funeral and nonprofit youth organization vehicles.

Penalties for a Car Seat Violation in Indiana

A car seat violation is a Class D infraction, which carries a maximum judgment of $25. If the driver shows the court that they had a proper child restraint, or got one afterward, and has no prior violations, the court enters judgment without a fine or court costs (IC 9-19-11-5 and IC 9-19-11-6). The BMV does not assess license points for the violation (IC 9-19-11-10), and it does not count toward habitual traffic violator status (IC 9-19-11-11). Money collected from these judgments goes to a state account that helps families who cannot afford a car seat get one (IC 9-19-11-9).

When Can a Child Ride in the Front Seat in Indiana?

No Indiana statute sets a minimum age for riding in the front seat. The law is about restraint, not seat position. Safety guidance is consistent, though: children 12 and under should ride in the back seat, and a rear-facing seat should never be placed in front of an active airbag. Our guide on when a child can sit in the front seat goes into more detail.

The Five-Step Seat Belt Fit Test

Age 8 is the legal line, but it is not a readiness test. Before moving a child out of a booster, check all five points in every vehicle the child rides in:

1. The child sits all the way back against the vehicle seat.
2. The child’s knees bend naturally at the edge of the seat.
3. The lap belt sits low across the upper thighs, not the stomach.
4. The shoulder belt crosses the middle of the chest and shoulder, not the neck or face.
5. The child can stay seated that way for the whole trip.

Most children pass between ages 8 and 12. If any step fails, the booster stays.

Common Car Seat Mistakes

• Turning forward too early. Moving a toddler to a forward-facing seat before the rear-facing limits are reached gives up protection for the head, neck, and spine.
• A loose installation or harness. An installed seat should move less than an inch side to side at the belt path, and the harness should be snug enough that you cannot pinch extra webbing at the collarbone.
• Using an expired seat. Car seats carry an expiration date, commonly six to ten years from the date of manufacture. Our article on booster seat expiration explains why it matters.
• Reusing a seat after a crash. NHTSA recommends replacing a car seat after a moderate or severe crash.
• Skipping the booster in someone else’s car. Carpools, grandparents’ cars, and rideshares are where boosters most often get left behind. See why a booster seat may not protect a child in every crash.

Certified child passenger safety technicians check installations for free at many fire departments, hospitals, and community events. You can find a nearby inspection site through NHTSA’s car seat resources or the Indiana State Police child passenger safety program.

Does Car Seat Use Affect a Child’s Injury Claim?

Insurance adjusters sometimes suggest a claim is worth less because a child was in the wrong seat or the seat was installed incorrectly. Indiana law limits that argument. IC 9-19-11-8 states that failing to comply with the child restraint chapter does not constitute contributory negligence. Under IC 9-19-10-7, evidence that a seat belt was not used generally cannot be admitted in a civil case to reduce damages, with a narrow exception for product liability claims about the restraint itself. Our article on how seat belt use affects an Indiana injury claim covers this in more depth, and the other driver’s share of fault is still measured under Indiana’s 51 percent comparative fault rule.

The seat itself can also be evidence. If a car seat, booster, or harness failed in a crash, the manufacturer may be responsible under Indiana product liability law. And because a child cannot settle a claim on their own, Indiana courts often have to approve the settlement. Our guide to how settlements for minors are approved explains that process.

What to Do After a Crash With a Child in the Car

1. Get the child checked. Have every child examined, even if they seem fine. Neck and abdominal injuries from belts and harnesses do not always cause symptoms right away.
2. Photograph the seat before removing it. Take pictures of the installation, the harness position, and any visible damage.
3. Keep the seat. Do not throw it away or return it. If the seat failed, it is the most important piece of evidence.
4. Get the crash report. The officer’s report usually notes restraint use for each occupant.
5. Be careful with the other driver’s insurer. Decline a recorded statement until you have talked with a lawyer.

Frequently Asked Questions

When can my child face forward in a car seat in Indiana?

Indiana law does not set an age for forward-facing. It requires a child under 8 to use a child restraint according to the manufacturer’s instructions, so the seat’s rear-facing height and weight limits control. Safety guidance recommends staying rear-facing until those limits are reached, which for many children is age 2 or later.

When can a child stop using a booster seat in Indiana?

A child must be in a child restraint system until age 8. After that, a seat belt is legal, but most children do not fit an adult belt correctly until they are about 4 feet 9 inches tall, usually between ages 8 and 12. Use the five-step fit test before making the switch.

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

It is a Class D infraction with a maximum judgment of $25. A first-time violator who shows the court a proper child restraint can avoid the fine and court costs, and the violation carries no license points.

Can a 10-year-old sit in the front seat in Indiana?

No Indiana law prohibits it, as long as the child is properly restrained. Safety agencies recommend that children 12 and under ride in the back seat because front airbags are designed for adults.

Do I need a new car seat after a car accident?

NHTSA recommends replacing a car seat after a moderate or severe crash, and some manufacturers require replacement after any crash. If the crash was someone else’s fault, the cost of a replacement seat can be part of the property damage claim.
