Mississippi Car Seat Laws (2023)- Age, Weight, Height Requirements

According to the Mississippi State Law, children who are younger than 7 years of age, weighing less than 65 pounds, and measuring less than 57 inches in height should be secured in a safety restraint device or a belt-positioning booster seat system.

That’s the overview of the age, weight, or height requirements for a child using a car seat. The laws provide more details. Let’s check what the Mississippi car seat laws say on what you need to know to ride a child in this State.

What is the car seat law in Mississippi?

Mississippi State Law Legislature Section 63-7-301 (1) (a) and (b) reads: "Every person transporting a child under the age of four (4) years in a passenger motor vehicle, [...] shall provide for the protection of the child by properly using a child passenger restraint device or system meeting applicable federal motor vehicle safety standards." "Every person [...] shall provide for the protection of the child by properly using a belt positioning booster seat system meeting applicable federal motor vehicle safety standards if the child is at least four (4) years of age, but less than seven (7) years of age and measures less than four (4) feet nine (9) inches in height or weighs less than sixty-five (65) pounds."

Mississippi Rear-Facing Car Seat Laws

The Mississippi law doesn’t s specifically mention the usage of the rear-facing car seat but only requires children under 4 years of age to ride in a child passenger safety device or system in Section 63-7-301 (1) (a).

The Mississippi State Department of Health implements the rules on rear-facing positions – infants and toddlers should travel in a rear-facing car seat until 2 years of age or they reach the weight or height limit set by the manufacturer.

The regulations from the National Highway Traffic Safety Administration and the American Academy of Pediatrics also suggest riding infants and toddlers in rear-facing for as long as possible, at least until the second birthday.

Mississippi Forward Facing Car Seat Laws

When can a child face forward in Mississippi?

The law does not say any age or weight requirement on forward-facing car seats.

However, it’s a common rule that the children should be secured in forward-facing car seats once the child outgrows the rear-facing car seat.

Interpreting the rules in Mississippi Legislature section 63-7-301 (1) (a) and (b), the forward-facing car seat can be used before the child is 4 years old.

But it’s not the safest practice.

The Mississippi State Department of Health recommends using a forward-facing car seat with a harness for toddlers and preschoolers when they’re within the highest weight or height limit of their forward-facing car seats.

That typically happens around age 57.

Child Booster Seat Laws in Mississippi

How old do you have to be for a booster seat in Mississippi?

The Mississippi law in section 63-7-301 (1) (b) says that belt-positioning booster seats should be used if the child meets the below age, weight, and height rules:

  • age 4 years or older but younger than 7 years old (age)
  • less than 4 feet 9 inches tall (height)
  • less than 65 pounds in weight (weight)

The Mississippi Department of Health states in its regulations that a booster seat should be used before the seat belt fits the child properly in size.

It’s best to keep your child in a high back or backless booster seat for as long as possible until he or she outgrows the booster seat.

Most booster seats on the market feature a weight limit between 100-120 pounds and a height limit between 57″-63″.

Seat Belt Laws for Child in Mississippi

The child seat belt law in Mississippi Legislature section 63-2-1 makes it clear that children under 18 years of age must ride with a properly fastened seat belt system.

The seat belt should be manufactured meeting the federal motor vehicle standard 208 and installed in the vehicle following the manufacturer’s instructions

Combining these regulations in section 63-2-1 on the seat belt and 63-7-301 (1) (b) on the child booster seat, it is supposed that a child can get out of a booster seat and start to wear a safety belt if they meet or exceed the listed age, weight, and height requirements in the following:

1) 7 years of age or older

2) 4 feet 9 inches or taller

3) 65 pounds or heavier

The Mississippi State Department of Health provides a few safety tips on seat belt usage.

Only when a child is old enough and large enough with the seat belt to fit them correctly, he or she shall ride with the vehicle’s seat belt system for security like an adult.

It’s best to use lap and shoulder seat belts for optimal protection if it’s possible.
