The section of KRS 189.125 3(a) of Kentucky law states the regulations that children less than 40 inches in height shall travel in a proper child restraint system.

The law does not mention any age, weight, or height requirements on rear-facing car seats.

However, according to the Kentucky Office of Highway Safety, you should keep your children in a rear-facing infant seat until they are 20 pounds and 12 months.

It’s best to keep a child in rear-facing as long as possible until they exceed the safety limit of the rear-facing car seats.

Kentucky Forward Facing Car Seat Laws

The Kentucky law does not indicate any age or size requirements on a forward-facing car. The common rule is to use a forward-facing seat once the child outgrows the rear-facing highest weight or height recommended by the car seat manufacturer.

The Kentucky Transportation department answers the question of when can a child go forward-facing and states that one child should be at least one year of age and 20 pounds to ride in a forward-facing car seat.

But it’s best to wait on your child’s second birthday and until they are 30 pounds or more to turn them from rear-facing to front-facing.

What is the height and weight of a booster seat in KY?

By law, in Kentucky legislature Regulations Section 189.125 (3) (b), a child shall ride in a booster seat if:

  • The child has outgrown the rear-facing/forward-facing seat
  • They are less than 8 years old
  • They are between 40” to 57” tall

If a child is over 57 inches tall, they are not required by law to ride in a booster seat. The booster should be installed with a lap-shoulder belt.

The height is the deciding factor in the KY booster seat law, it’s best to keep your child in a booster seat until they reach 57 inches, regardless of age, or weight.

Seat Belt Laws for Child in Kentucky

The KY law is not clear on the age, weight, or height requirement for a child to use the vehicle seat belt.

It just says that children are not required to use a booster seat when they are more than 57 inches tall.

That means, children who meet this height requirement are ready to use a seat belt like an adult.

You can also check if the seat belt fits your child properly or not by asking yourself several questions. When your child is sitting all the way back:

  • Does his or her knees bend comfortably over the edge of the seat?
  • Does the lap belt stay low across the hips?
  • Does the shoulder belt across the chest and stay between the neck and shoulder?
  • Can your child sit like this for the whole trip without slouching?

If the answers to these questions are “Yes”, then your child can get out of the boosters and use a seat belt.

When can a child sit in the front seat in Kentucky?

There is no age mentioned when a child can sit in the front seat in the Kentucky law. However, the Kentucky Department of Transportation says that you should follow the best practice of keeping your child in the back seat until the age of 12.

That’s also a common rule suggested by child safety experts and NHTSA guidelines.
