How Iowa car seat law works
Iowa is one of the states that actually legislates the rear-facing stage, but it does so narrowly: the rule applies only to a child who is under 1 AND under 20 lb, so both conditions have to be met. After that, the law simply requires an appropriate child restraint system until age 6, and it lets that be a safety seat or a booster without naming a forward-facing age. The booster exit is age 6 alone. There is no 4′9″ height line and no weight line in the Iowa statute, so a child is legally clear of the restraint requirement at 6 regardless of size. Iowa also has no front-seat age law; back-seat-until-12 is a recommendation. The scheduled fine is $100, and a first-time offender for the youngest children avoids conviction by showing proof of buying a qualifying restraint.
