4′9″ = 57 in. Enter only the boxes you have. Wyoming uses required until age 9; the statute names age, weight, and height as factors but sets no specific numbers, so any “4′9″” or “80 lb” figure is guidance, not Wyoming law.
Wyoming 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 Wyoming 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 Wyoming, 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 Wyoming car seat law reference, cited to Wyo. Stat. §31-5-1303 (last reviewed 2026-07-11).
How Wyoming car seat law works
Wyoming keeps its child-restraint rule short and age-based: every child under 9 must be in a restraint appropriate for the child’s age, weight, and height. The statute names those three factors but does not set numbers, so there is no “4′9″” or “80 lb” line in Wyoming law, and the booster exit is simply age 9. Because the statute is silent on orientation, rear-facing until 2 is best practice here, not a legal requirement. What Wyoming does legislate is placement: a child under 9 must ride in a seat other than the front unless the back is full or the vehicle has one row, and a rear-facing seat may never sit in front of an active airbag. The fine is about $50 first offense, dismissible if you buy the right restraint afterward.
