Car Seat & Booster Law Checker by State
Enter your child's age, height, and weight to see the minimum seat stage your state's 2026 law requires (car seat, booster, or seat belt), plus the first-offense fine. This is the legal minimum, not best safety practice.
Pick your state
Each checker applies that state's own age/height/weight exit rule.
How the car seat checker works
Each state checker runs your child's age, height, and weight through that state's exact booster→belt exit rule (some use age or height, some weight, some age alone) and shows the minimum stage the law requires, plus the fine for a first offense. It shows the legal minimum, which is often more lenient than what safety groups recommend.
This tool is informational only, not legal or safety advice. Best practice (rear-facing to age 2+, harness, then booster) is frequently stricter than the law. Always follow your car seat's manufacturer instructions and confirm the current rule on each state page.
