Car seat laws in Indiana

Indiana law has no rear-facing requirement. NHTSA and the AAP recommend keeping your child rear-facing as long as possible, until they reach the top height or weight limit allowed by the car seat's manufacturer. A child under age 1 should always ride rear-facing, and most convertible seats allow rear-facing for 2 years or more.

A child less than eight must be properly fastened and restrained by a child restraint system according to the manufacturer's instructions. The state says this can include a belt-positioning booster. NHTSA and the AAP recommend going further: using a belt-positioning booster seat after your child outgrows the harnessed seat, until the vehicle seat belt fits properly, typically when they reach about 4 feet 9 inches tall and are 8 to 12 years old. The AAP says an adult seat belt fits when: the shoulder belt lies across the middle of the chest and shoulder, not the neck or throat; the lap belt is low and snug across the upper thighs, not the belly; and the child is tall enough to sit against the vehicle seat back with knees bent over the edge of the seat without slouching, and can stay that way for the whole trip. NHTSA uses the same lap-belt and shoulder-belt checks. The 5-step test, which California writes into law from January 1, 2027, asks: 1) Does the child sit all the way back against the seat? 2) Do the knees bend over the edge of the seat? 3) Does the shoulder belt snugly cross the center of the chest and shoulder, not the neck? 4) Is the lap belt as low as possible, touching the thighs? 5) Can the child stay seated like this for the whole trip?

No Indiana law says where in the car a child must sit. NHTSA and the AAP recommend keeping all children younger than 13 in the back seat.

A Class D infraction, with a judgment of up to $25. If it's your first violation and you have or acquire a child restraint system, you're not liable for any costs or monetary judgment.
