For toddlers, the weight limit is 20-40 pounds, and they must be in a rear-facing or front-facing convertible car seat or a 3-in-1. Children 4-8 years old must weigh 40-100 lbs. and be in a front-facing booster car seat. All car seats must be secured through a harness strap for infants or toddlers, and a seat belt for children 4 years or older. Below are the three types of car seats approved by Kansas car seat laws.

Every civilized society has laws that guide every action of a person resident, passing through, or on a tourist visit. It is essential to get familiar with the Kansas car seat laws, especially, if you have children below the age of fourteen. No one will want to pay a fine for violating the Kansas car seat law when out for fun with their kids.

Infant Car Seat- Rear-facing car seat Law

In Kansas, all children under the age of four must be securely buckled into a federally approved child safety seat or in a vehicle manufacturer’s integrated child safety seat, no matter where they’re seated in the vehicle. An infant is a baby that is less than 12 months old. They are to be placed in a rear-facing car seat. If the seat is an infant-only car seat, ensure to only use it in the rear-facing position.

The infant car seats which, are specially designed for newborns and small babies, are portable and convertible types of seats. The seat is designed to be used in a rear-facing position. If your baby outgrows the seat before the age of 12 months of age, you can switch to a convertible seat or a 3-in-1 and continue to use it in the rear-facing position.

Age Infant (birth to one year old)

Weight Up to 20 pounds (varies by seat manufacturer)

Car Seat Type Infant-only seat or Convertible in a rear-facing position

Seat Direction Rear-facing only

Harness Straps Should be at or below shoulder level 

Kansas car seat laws allows children between the ages of one and three to sit in a forward-facing car seat the moment they outgrow their rear-facing infant seat. The car seat is recommended to be fastened in the back seat because it is safer.

According to the National Highway Traffic Safety Administration, a rear-facing car seat is the best type of seat for young children to use. This type of car seat includes a harness, which keeps the child tightly secured and cradled in the seat during a crash.

A harness moves with the child on impact and reduces the chances of injury to the neck and spinal cord. 

At the minimum, your child must be in a rear-facing car seat until they are at least one year old and at least 20 pounds (or the seat’s upper limits). However, it’s recommended that your child stays in the rear-facing position until they reach 35 pounds, or whatever the car seat’s weight limit is. 

Convertible Car seat- rear-facing and forward-facing car seat law

Convertible car seats or 3-in-1 car seats are best for children as they grow older. They usually have higher weight limits for rear-facing placement, which allows you to keep your child in a rear-facing seat for longer than an infant-only car seat.

Convertible seats can convert from rear-facing to forward-facing using a harness and tether. The 3-in-1 (or all-in-one) type can convert from rear-facing to forward-facing to a booster seat. 

Age Over 1 year old (toddler – preschool age)

Weight 20-40 pounds

Car Seat Type Convertible or 3-in-1

Seat Direction Rear-facing or front-facing (depends on seat limits)

Harness Straps Should be at or above shoulder level 

All-in-one car seat Law in Kansas

New parents tend to go for the infant car seat, especially if they are not familiar with the all-in-one car seat. The uniqueness of an all-in-one car seat is that it grows with the child. A child of as little as 5 pounds to a child of 120 pounds can use the seat. It can be used as an infant seat, booster seat, rear-facing, and forward-facing seat. It can also be referred to as a 3-in-1 or 4-in-1 car seat.

An All-in-one car seat is convenient and environmentally friendly, and your child grows with it.

Booster Car Seat Laws in Kansas

In Kansas, children aged four to eight, those under 80 pounds, or those who are under 4’9” tall, must be restrained using a booster seat with a lap and shoulder belt when available. 

The safest option is to keep your child in their forward-facing car seat as long as possible. Once your child reaches the seat’s upper height and/or weight limit, it’s time to switch to a booster seat. 

The booster seat should still be placed in the vehicle’s back seat for the safest conditions. 

All children who are ages 4, 5, 6, or 7 must ride in a booster seat unless one of the following conditions are met: 

  • The child is 4 feet 9 inches tall or taller
  • The child weighs 80 or more pounds
  • The vehicle only has a lap belt available

In any of those cases, the child must be restrained by the vehicle’s seat belt system if the booster isn’t used. 

Age 4-8 years

Weight 40-100 lbs. (check booster seat’s specifications)

Car Seat Type Belt-positioning booster seat

Seat Direction Front-facing

Seat Belt Must be used with both the lap belt and shoulder belt when available.

Once the child reaches age 8, they may ride using a seat belt only. However, it’s recommended that the child be at least 4’9” tall and weigh 80 pounds before switching to a standard seat belt. And you must ensure that the child is big enough for the seat belt to fit properly before ditching the booster seat. 

For a seat belt to fit properly and safely restrain your child, the lap belt must fit snugly over the top of the thighs, not across the child’s stomach. In addition, the shoulder belt should fit snugly over the shoulder and chest, not across the child’s neck or face. 

If the seat belt doesn’t fit across the child’s body properly and in the proper positioning, then they need to stay in their booster seat a little longer.

It’s also a good idea to consider your child’s maturity and whether they can sit properly without playing with or disengaging the seat belt.

When Can a Child Sit in the Front Seat in Kansas?

According to the Kansas Traffic Safety Resource Office, all children under the age of 12 should sit in the back seat. The back seat is the safest place for a child. 

While there aren’t any rules codified as law in Kansas about when children can sit in the front seat, there is still general guidance we can follow.

However, if a child must ride in the front seat, you should slide the seat back as far as possible to avoid airbag impact. This is especially important for children riding in a front-facing car seat. Children in a rear-facing car seat should never ride in a front seat. 

Kansas Laws On Leaving A Child Unattended In A Car

In Kansas, it’s illegal to leave a child unattended in a vehicle for an extended period.

According to Senate Bill No. 77, drivers may not leave children who are ages 5 or under unattended and unsupervised in a vehicle for more than five minutes unless the vehicle is being loaded or unloaded.

If any law enforcement officer observes a child unattended and unsupervised in a vehicle is authorized to remove the child from the vehicle using any means necessary. Drivers who violate the law can be cited and fined.

  • If the car seat is front-facing with a tether strap, ensure that you connect the tether anchor and tighten the strap. This feature helps prevent whiplash or injury to the neck, head, or spinal cord during a collision.
