NHTSA

Children under age 1 should always ride in a rear-facing car seat. Keep your child rear-facing as long as possible — it's the best way to keep them safe — until they reach the top height or weight limit allowed by the car seat's manufacturer.

NHTSA – Car Seats and Booster Seats

AAP

All infants should ride rear-facing, starting with their first ride home from the hospital, and should continue riding rear-facing as long as possible until they reach the highest weight or height allowed by their car safety seat's manufacturer.

NHTSA

Once a child outgrows the rear-facing car seat, they are ready for a forward-facing car seat with a harness and tether. Keep the child in the forward-facing seat until they reach the top height or weight limit allowed by the car seat's manufacturer, then move to a booster seat, still in the back seat.

NHTSA – Car Seats and Booster Seats

AAP

Children should use a forward-facing car seat with a harness after outgrowing the rear-facing weight or height limit. It is best for children to ride in a seat with a harness as long as possible, at least to 4 years of age.

HealthyChildren.org (AAP) – Car Safety Seats: Information for Families

Booster seat

Statute text

When any child who is less than eight years of age and less than four feet nine inches in height, who is not required by division (A) or (B) of this section to be secured in a child restraint system, is being transported in a motor vehicle, other than a taxicab or public safety vehicle as defined in section 4511.01 of the Revised Code or a vehicle that is regulated under section 5104.015 of the Revised Code, that is required by the United States department of transportation to be equipped with seat belts at the time of manufacture or assembly, the operator of the motor vehicle shall have the child properly secured in accordance with the manufacturer's instructions on a booster seat that meets federal motor vehicle safety standards.

ORC 4511.81(C). Before this stage, division (A) requires a child restraint system for a child under four years or under 40 pounds.

What the law sets

Booster required by law
Yes
Booster until age
8 years
Booster until weight
Not addressed in statute

Not set in ORC 4511.81(C).

Booster until height
57 in (4 ft 9 in)

The rule covers a child "less than four feet nine inches", so a child who reaches exactly 57 inches is no longer covered.

Leaving the booster
Meeting any one listed limit is enough

The booster rule covers a child under eight AND under 4 feet 9 inches, so reaching either eight years or 4 feet 9 inches ends it.

Recommended (not law)

NHTSA

Keep your child in a booster seat until they are big enough to fit in a seat belt properly — the lap belt lying snugly across the upper thighs (not the stomach) and the shoulder belt snug across the shoulder and chest (not the neck or face).

NHTSA – Car Seats and Booster Seats

AAP

All children whose weight or height exceeds the forward-facing limit for their car safety seat should use a belt-positioning booster seat until the vehicle seat belt fits properly, typically when they have reached 4 feet 9 inches in height and are 8 to 12 years of age.

HealthyChildren.org (AAP) – Car Safety Seats: Information for Families

Seat belt

Statute text

When any child who is at least eight years of age but not older than fifteen years of age, and who is not otherwise required by division (A), (B), or (C) of this section to be secured in a child restraint system or booster seat, is being transported in a motor vehicle, other than a taxicab or public safety vehicle as defined in section 4511.01 of the Revised Code, that is required by the United States department of transportation to be equipped with seat belts at the time of manufacture or assembly, the operator of the motor vehicle shall have the child properly restrained either in accordance with the manufacturer's instructions in a child restraint system that meets federal motor vehicle safety standards or in an occupant restraining device as defined in section 4513.263 of the Revised Code.

ORC 4511.81(D). Under ORC 4511.81(E), divisions (C) and (D) are secondary: an officer may not stop a vehicle solely to check them.

What the law sets

Seat belt alone from age
8 years
Seat belt alone from height
57 in (4 ft 9 in)

A child who is 57 inches or taller is outside division (C).

Moving to the seat belt
Meeting any one listed limit is enough

Recommended (not law)

NHTSA

Once a child is big enough to fit in a seat belt properly, they can ride with just the lap-and-shoulder belt, but should still ride in the back seat — NHTSA recommends keeping children in the back seat at least through age 12.

NHTSA – Car Seats and Booster Seats

AAP

Children should transition to the vehicle seat belt once it fits properly, typically at about 4 feet 9 inches in height and 8 to 12 years of age; all children younger than 13 years should ride in the back seat.

HealthyChildren.org (AAP) – Car Safety Seats: Information for Families

Front seat

Many states have no front-seat age in statute. Where that is the case, we say so and cite the section we read.

Front seat — statute text
Not addressed in statute

No front-seat provision in ORC 4511.81.

Minimum age for the front seat
Not addressed in statute

No front-seat provision in ORC 4511.81.

Conditions
Not addressed in statute

No front-seat provision in ORC 4511.81.

Penalties

What a car seat ticket costs, and whether showing proof of a proper seat can cancel it.

First offense — fine
$25 – $75

ORC 4511.81(L)(1)(a): minor misdemeanor, fine of not less than $25 nor more than $75. Several unrestrained children at the same time and place count as one violation.

Repeat offense — fine
Up to $250

ORC 4511.81(L)(1)(b): with a prior conviction the offense is a fourth-degree misdemeanor; ORC 2929.28(A)(2)(a)(iv) caps that fine at $250.

License points
2 points

ORC 4510.036(C)(16) assesses 2 points for moving violations not listed elsewhere; ORC 4510.01(E) defines a moving violation as any violation of a statute regulating vehicle operation and excludes the seat belt law (ORC 4513.263) but not ORC 4511.81. Child restraint violations are not named in the schedule. This value is inferred from the catch-all, not from a provision that names ORC 4511.81.

Fine waiver
Not addressed in statute

Not set in ORC 4511.81; division (K) only makes a birth certificate showing the child is outside the covered age a defense.

Exemptions

Exempt means the statute excludes it. Silent means the statute does not address it.

Taxis
Exempt

ORC 4511.81(A), (C) and (D) exclude taxicabs by name.

Rideshare (Uber, Lyft)
Not addressed in statute

ORC 4511.81 does not address transportation network companies.

Buses
Not addressed in statute

ORC 4511.81 does not name buses; it applies to motor vehicles required by the U.S. Department of Transportation to have seat belts when built.

Medical exemption
Exempt

ORC 4511.81(H): a driver with an affidavit from a physician, clinical nurse specialist, certified nurse practitioner or chiropractor stating that a physical impairment makes restraint impossible or impractical.

Out-of-state vehicles
Not addressed in statute

ORC 4511.81 does not address nonresident drivers or out-of-state vehicles.

How Ohio compares

Ohio is tied for 6th of 47 jurisdictions with a numeric booster age: 33 jurisdictions, including Ohio, require a booster until age 8.

Compared with Indiana, Kentucky, Michigan, Pennsylvania, and West Virginia, Ohio differs on: rear-facing rules (from Michigan and Pennsylvania), booster rules (from Indiana and Pennsylvania), and front-seat rules (from Michigan).

Law compared with the AAP recommendation

  • Ohio law does not address this stage. AAP recommends: All infants should ride rear-facing, starting with their first ride home from the hospital, and should continue riding rear-facing as long as possible until they reach the highest weight or height allowed by their car safety seat's manufacturer.
  • Ohio law does not address this stage. AAP recommends: Children should use a forward-facing car seat with a harness after outgrowing the rear-facing weight or height limit. It is best for children to ride in a seat with a harness as long as possible, at least to 4 years of age.
  • Ohio law: a booster seat is required until the child reaches age 8 or 57 in, whichever comes first. AAP recommends: All children whose weight or height exceeds the forward-facing limit for their car safety seat should use a belt-positioning booster seat until the vehicle seat belt fits properly, typically when they have reached 4 feet 9 inches in height and are 8 to 12 years of age.
  • Ohio law: a child may use the seat belt alone once reaching age 8 or 57 in, whichever comes first. AAP recommends: Children should transition to the vehicle seat belt once it fits properly, typically at about 4 feet 9 inches in height and 8 to 12 years of age; all children younger than 13 years should ride in the back seat.
