What the Oklahoma booster seat law says
The stages below are separate rules in the statute, not one rule in steps.
| Rule | Figure | What Oklahoma requires |
|---|---|---|
| Rear facing | under 24 months | Until 24 months (2 years). |
| Car seat or booster | under 8 years | Until age 8, unless the child is taller than 57 inches (4 ft 9 in). |
| Adult seat belt alone | from 8 years | Lawful from age 8, or once the child reaches more than 57 inches (4 ft 9 in). |
| Penalty | $50 | $50 for a first offense. Condition Fifty dollars plus all court costs under 11-1112(F). On a first offense the fine is suspended and court costs are capped at fifteen dollars on proof of purchase or of acquisition by loan of a restraint. The Department of Public Safety assesses no points for this section. |
Size ends the requirement, whichever comes first. A child who is taller than 57 inches (4 ft 9 in) is out of the booster in Oklahoma whatever their age. A child who has not reached that stays in one until age 8. The size is an escape from the age rule rather than a second thing that also has to be true.
Where this and size guidance disagree, follow the stricter one. A belt that crosses the neck rather than the middle of the chest is worse protection than a booster even where the statute allows it.
The statute
Oklahoma sets this in 47 O.S. § 11-1112. Read it at the source.
This is information, not legal advice. A city or county in Oklahoma can set a stricter rule than the state one, and an officer enforces the text of the statute rather than a summary of it. Where this page and the statute differ, the statute is right and this page is a bug.
