Car seat laws in Iowa

A child under one year of age and weighing less than twenty pounds must be secured in a rear-facing child restraint system used according to the manufacturer's instructions. NHTSA and the AAP recommend going further: 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 under six years of age must be secured by a child restraint system used according to the manufacturer's instructions. The definition includes belt-positioning and booster seats. 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 Iowa 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 simple misdemeanor with a scheduled fine of $135. If it's your first charge under the age-6 rules and you had no child restraint, you won't be convicted if you show the court in time that you've since bought or acquired one.
