Indiana vs Ohio

Indiana and Ohio write some of the simpler child restraint laws in the Midwest, and they look alike at a glance: neither sets a rear-facing age, and both move a child out of a required seat around age 8. The difference is in how each ends the booster stage and how each treats taxis. Indiana requires a child under 8 to be in a child restraint system, full stop, with no height shortcut. Ohio releases a child at age 8 OR once they reach 4 feet 9 inches, whichever comes first. That gives Indiana the edge on a tall younger child, and combined with Ohio's taxi exemption it makes Indiana the marginally stricter state, even though Ohio carries a clearer fine.

Indiana keeps every child under 8 in a child restraint regardless of height, so a tall 6 or 7 year old still needs a booster until their 8th birthday. Ohio lets that same tall child move to the seat belt as soon as they reach 4 feet 9 inches, even before age 8. For a child of average height the two laws land in the same place around age 8. The American Academy of Pediatrics recommends keeping any child in a booster until the seat belt fits correctly, usually near 4 feet 9 inches and between ages 8 and 12, which is the safer practice in both states no matter what the minimum allows.

Neither state sets a rear-facing or forward-facing age. Indiana requires a child under 8 to be in a child restraint used per the manufacturer's instructions. Ohio requires a child under 4 years old or under 40 pounds to be in a child safety seat, then a booster from there to age 8. So both states leave the rear-facing decision to the parent and the seat manufacturer, and a parent of an infant or toddler will not find a statutory rear-facing requirement on either side of the line. Pediatricians recommend rear-facing as long as the seat allows in both states.

Ohio prints a clear fine: $25 to $75 for a first offense, rising to a fourth-degree misdemeanor for a repeat. Indiana treats a violation as a Class D infraction with the amount set by the infraction schedule rather than stated in the section, so Ohio's penalty is the more visible of the two. The states also differ on taxis: Ohio exempts certain vehicles such as taxis and buses, while Indiana has no general taxi or rideshare exemption (its only carve-out is a medical certification). The rule that applies is the rule of the state you are driving in. Indiana and Ohio meet along I-70, I-74, and US 27 between Indianapolis, Dayton, and Cincinnati. To stay legal across the whole trip, keep any child under 8 in a booster even if they have reached 4 feet 9 inches, which satisfies Indiana's stricter rule and stays inside Ohio's.
