After reviewing hundreds of car seats over the past decade, I can tell you that Kentucky’s child restraint law is one of the more straightforward ones to follow — but the $30 fine for violations barely scratches the surface of what’s really at stake for your child’s safety.
Kentucky saw 814 traffic fatalities in 2023, with 47% of vehicle occupants killed in 2024 not wearing a seat belt. When nearly half of crash victims are unrestrained, it’s clear that proper restraint use — starting from infancy — is a life-or-death decision.
This guide breaks down every part of Kentucky’s car seat requirements under KRS 189.125, from rear-facing seats through booster seats, so you know exactly what the law requires at each stage of your child’s growth.

Kentucky car seat laws by age
Rear-facing car seats: Kentucky law requires all children under 40 inches tall to be secured in a child restraint system. While the statute doesn’t specify a separate rear-facing requirement, the American Academy of Pediatrics and NHTSA strongly recommend keeping children rear-facing until at least age 2, or until they reach the maximum height and weight limits of their rear-facing seat. For maximum protection, keep your child rear-facing as long as the seat allows.
Forward-facing car seats: Children who have outgrown their rear-facing seat but are still under 40 inches tall must remain in a harnessed car seat. Kentucky’s law uses height rather than age as the threshold — children under 40 inches must be in a child restraint device regardless of age. Most children reach 40 inches between ages 3 and 5.
Booster seats: Under KRS 189.125, children under 8 years old who are between 40 and 57 inches tall must ride in a booster seat. The booster seat positions your vehicle’s seat belt correctly across the child’s chest and lap. Once a child reaches 57 inches tall or turns 8, they may transition to a regular seat belt.
Seat belt: Children 8 years old or older, or those taller than 57 inches, must wear a seat belt. Kentucky’s seat belt law applies to all passengers regardless of seating position.
Back seat recommendation: While Kentucky doesn’t have a specific back-seat law for children, safety experts strongly recommend that all children 12 and under ride in the back seat where they are safest from airbag injuries.

Fines and enforcement
Kentucky treats child restraint violations as follows:
The fine for violating the child restraint law is $30, with no additional court costs. For booster seat violations specifically, the fine is up to $25 with no court costs or additional fees.
Kentucky has a primary enforcement seat belt law, meaning law enforcement officers can pull you over solely for an unrestrained child — no other traffic violation needs to be observed first.
Fine waiver option: If you’re cited for a booster seat violation, you can have the charge dismissed by purchasing a booster seat and presenting proof of acquisition to the court. This is a one-time opportunity that encourages compliance over punishment.
No points are assessed on your driving record for a child restraint violation in Kentucky.
Special situations
Taxis and rideshares: Kentucky’s child restraint law applies to all motor vehicles. If you’re using a taxi or rideshare service like Uber or Lyft, you are still responsible for providing an appropriate car seat for your child. Consider a portable travel car seat for these situations.
Vehicles without back seats: If your vehicle doesn’t have a back seat (such as a pickup truck with a single cab), children may ride in the front seat with an appropriate restraint device. However, never place a rear-facing car seat in front of an active airbag.
Leaving a child unattended: Kentucky law prohibits leaving a child under 8 years old unattended in a vehicle if conditions present a risk to the child’s health or safety.
Crash replacement: Car seats involved in a moderate-to-severe crash should be replaced immediately, even if there’s no visible damage. Many car seat manufacturers offer free replacement after a crash. Check with your insurance company as many policies cover the cost. For more guidance, see our guide on what to do with old car seats.
What to do if you get a ticket
If you receive a child restraint citation in Kentucky, here’s your action plan:
1. Take advantage of the fine waiver. For booster seat violations, purchase an appropriate booster seat and bring proof to court. The charge will be dismissed with no fees or costs.
2. Get a free or low-cost car seat. Kentucky has several programs that provide free car seats to families in need, including through local health departments and Safe Kids coalitions. Visit our free car seats in Kentucky page for a complete list of resources.
3. Get your installation checked. NHTSA estimates that nearly half of all car seats are installed incorrectly. Find a certified car seat technician near you through the NHTSA car seat inspection locator to make sure your child’s seat is properly installed.
