Mississippi Car Seat Laws: A Brief Overview

Mississippi car seat laws are designed to protect children from potential harm while riding in motor vehicles. The laws are based on a child's age, weight, and height, with specific requirements in place to ensure their safety.

1. Key Age Groups

Mississippi car seat laws apply to different age groups, such as:

  • Infants and toddlers (birth to 2 years old)

  • Preschoolers (2 to 4 years old)

  • School-aged children (4 to 7 years old)

  • Tweens and teenagers (8 to 18 years old)

2. Seat Types

Mississippi car seat laws require the use of specific seat types based on a child's age and size, including:

  • Rear-facing car seats

  • Forward-facing car seats

  • Booster seats

  • Seat belts

Mississippi Car Seat Laws: The Specifics

Now that we've laid the groundwork, let's delve deeper into Mississippi car seat laws and the specifics for each age group.

Infants and Toddlers: Birth to 2 Years Old

Mississippi car seat laws mandate that children under two years old must be placed in a rear-facing car seat. This type of seat provides the best protection for a child's head, neck, and spine in case of a crash.

Children should remain in a rear-facing car seat until they reach the height or weight limit specified by the car seat manufacturer.

Preschoolers: 2 to 4 Years Old

Once a child outgrows their rear-facing car seat, they should transition to a forward-facing car seat with a five-point harness. Children should remain in a forward-facing car seat until they reach the height or weight limit specified by the car seat manufacturer.

School-aged Children: 4 to 7 Years Old

When a child outgrows their forward-facing car seat, they should transition to a booster seat. Booster seats help position the seat belt correctly across a child's body, ensuring their safety. 

Children should use a booster seat until they are at least 4 feet 9 inches tall and can pass the seat belt fit test. According to the Centers for Disease Control and Prevention, booster seats can reduce the risk of injury by 45% for children aged 4 to 8 years old, compared to seat belts alone.

Tweens and Teenagers: 8 to 18 Years Old

Mississippi car seat laws require all passengers aged 8 to 18 years old to wear a seat belt while riding in a motor vehicle. The lap belt should fit snugly across the upper thighs, and the shoulder belt should lay across the chest and shoulder, avoiding the neck or face.

Importance of Proper Installation and Usage of Car Seats

Proper installation of car seats and booster seats is crucial to ensure your child's safety. Here are some tips to help you install them correctly:

  1. Always follow the car seat manufacturer's instructions.

  2. Make sure the car seat is tightly secured and doesn't move more than one inch side-to-side or front-to-back.

  3. Use either the vehicle's seat belt or the LATCH system, but not both.

  4. Perform the "inch test" and the "pinch test" to ensure a snug fit.


Mississippi car seat laws are designed to keep children safe while traveling. By understanding the law and practicing safe driving, parents and caregivers can ensure their child's safety and prevent potential tragedies on the road.

Remember to always use the appropriate car seat or booster seat for your child's age, weight, and height and to install and use it correctly. Stay informed and stay safe.
