Ohio Rear-Facing Car Seat Laws

According to Ohio law, children must travel in a car seat when they are less than 4 years old or under 40 pounds. No rear-facing is mentioned in the law, but the car seat needs to be suitable for the child’s weight and height.

The best practice is to keep a child in a rear-facing car seat until the age of 2 or until reaching the maximum height or weight set by the car seat manufacturer.

Not specific requirements on rear-facing

Less than the minimum weight limit for a forward-facing seat

If so, have your baby in the infant car seat until they reach the weight or height limit of the car seat, generally 35 pounds or 32 inches, which does not violate the Ohio car seat laws on rear-facing.

The safest practice is to keep your kid in the rear-facing position for as long as possible.

The same case happens to the forward-facing. Ohio law does not specify the age, weight, and height requirements on forward-facing car seats. At this time, it’s best to follow the guidelines of AAP and NHTSA – Use a forward-facing car seat when the child outgrows their rear-facing car seat.

By law, the forward-facing seats are required to be used until a child is 4 years old and weighs at least 40 pounds.

It’s best to keep your child in the forward-facing car seat as long as they are still within the upper weight or height limit of their car seats.
