4′9″ = 57 in. Enter only the boxes you have. Utah uses required while under 8; reaching age 8 OR 4′9″ (57 in) exits the restraint.
Utah does not legislate rear-facing vs forward-facing by age; it requires a restraint appropriate per the manufacturer's instructions. Best practice from AAP (the pediatricians' association) and NHTSA (the federal highway-safety agency), not Utah law: rear-facing to age 2+, then a harness, then a booster.

Plain-language summary, not legal advice.
This shows the minimum legal requirement in Utah, not best safety practice, which is usually stricter, and not legal or safety advice. Always follow your car seat's manufacturer instructions. For the full four-stage rules, front-seat rule, and citation, see the Utah car seat law reference, cited to Utah Code §41-6a-1803 (last reviewed 2026-07-11).
How Utah car seat law works
Utah writes its child-restraint rule around age and height, not orientation. A child younger than 8 must ride in a car seat or booster used the way the manufacturer directs, and the one built-in exit is height: a child under 8 who reaches 4′9″ (57 in) may move to a properly fitted safety belt. Because the statute is silent on rear- versus forward-facing, the familiar “rear-facing until 2” is best practice here, not Utah law. Utah also sets no rear-seat placement rule, so keeping a child in back is a recommendation rather than a requirement. The dollar penalty is not in §41-6a-1803 itself; the roughly $45 figure comes from the court fine schedule, and a first offense is commonly waived when a driver later shows a restraint was purchased.
