Car seat laws in Indiana require all children younger than eight years old to appropriately use a child restraint system. Booster seat laws are included within this framework, since booster seats can be considered to be child restraint systems.


Knowing and understanding these child car seat safety laws is vital for any parent, as well as for any caregiver or babysitter. Any driver transporting a child is required to follow these laws, whether or not you are the parent. Also, your state of residency does not matter because every driver transporting a child through Indiana is required to abide by these laws.

Booster seat age limitations usually exist according to a manufacturer, but it is also important to understand the car seat ages and requirements according to state law.

In Indiana, the weight and height of a child can alter the requirements of age groups, so it is important for you to review the manufacturer’s details for the seat you purchase in combination with legal requirements so as to meet all criteria and keep your child safe.

What are the car seat laws in Indiana?

Indiana child car seat laws require all children younger than the age of eight to use a child car seat or a booster seat. There are additional requirements based on age and weight that you must adhere to, so be sure to review the details below:

  1. An infant car seat must be used for newborns up to the age of one or to a weight of 20 pounds. This must be a rear-facing seat according to state law. It is advised that you keep your child rear facing for as long as possible.
  2. Weight limits begin around 20 pounds, when children aged at least one year and older who are 20 pounds or heavier can use a forward-facing car seat instead of a rear facing one. The new seat must have an internal harness system.
  3. Booster seat weight limits begin at children weighing at least 30 pounds. However, it is recommended that you keep a child in a car seat for as long as possible.
  4. The age limit is up to eight years old, when it is a requirement to use a restraint system. This typically means a booster seat once the child weighs 45 pounds but can differ for your child and your particular car seat limitations.

Penalties for Violating Car Seat Regulations in Indiana

Car seat safety for children is the responsibility of the driver of any vehicle transporting a child younger than eight years old. Additionally, any child aged between eight and 16 years is required to wear a seat belt, which should be overseen by the driver.

Violations of the laws dictating car or booster seat weight requirements or ages for car seats can result in penalty fines being assessed, in addition to points being added to your license. Be sure to comply with all Indiana car seat regulations, whether you live in the state or are just passing through with child passengers.

Types of Car Seats

The safest car seats are evaluated on a regular basis by the government and by consumer protection agencies. You can always check the best car seats available through those ratings systems to ensure you purchase a quality seat. Many of the most popular brands, such as Chicco, Evenflo and Graco, are frequently at the top of those ratings.

When looking at car seat types, it is important to know the various types available. A rear-facing car seat, sometimes called an infant car seat, is required for children from birth until the child is at least one year old.

A forward facing car seat is usually the next step, once your child gets too tall or too big to use the rear-facing seat. It is recommended that you keep your child in a rear-facing seat for as long as possible.

A convertible car seat can be used in both the rear facing and forward-facing directions, so you could use this type of seat for a longer period of time. This could be a good option to allow your child to grow without needing multiple seating options.

Booster car seats should generally be used starting around four years old. Regardless of age, children should use booster seats in the back seat of the car until a regular seat belt can be used safely. Remember that children up to the age of eight are required to use a child restraint system, so a booster seat could be a good option for a few years.

Car Seat Installation Information

Comprehending the car seat installation requirements can be a challenge for new users of these systems. To ensure you install a car seat correctly, follow these tips:

  1. Go through the entire car seat instruction manual front-to-back to make sure you understand the car seat or booster seat you just bought.
  2. Read the relevant section of your vehicle manual to ensure you understand the requirements for your specific vehicle when installing a car seat. Pay particularly close attention to how to lock the seat belt, if you are installing by that method.
  3. Put the car seat in the back seat of your vehicle, preferably in the center seat. If it is forward facing with a tether strap, connect the tether anchor and tighten it. If it is rear facing, check the recline angle.
  4. Make sure the seat is securely tightened. It should not move more than one inch in any direction when you pull on it. The retainer clip connecting the two shoulder harness straps should stay at the child’s armpit level and harness straps should be tight.
  5. Double-check the installation every time you use it. With time and general wear and tear, car seats become loose and less effective. Be sure to stay vigilant and to upgrade your safety measures as your child grows.

The Indiana Criminal Justice Institute (ICJI) offers child passenger safety education, which includes car seat safety inspection stations where you can have your child car seat installation checked by a certified technician. Be sure to take advantage of these opportunities to ensure you are complying with the laws and keeping your child as safe as possible.
