If you are raising kids in the Magnolia State, understanding the Mississippi law for booster seats is one of the simplest ways to keep your child safe and avoid an unnecessary ticket.
Mississippi’s child restraint rules are built around age, height, and weight, and knowing exactly where your child falls can save you a headache at your next traffic stop.
What Mississippi Law Says About Child Restraints
Mississippi’s child passenger safety rules fall under Section 63-7-301 of the state’s Motor Vehicles and Traffic Regulations. This statute breaks requirements down by age group rather than treating every child the same way.
Children Under 4 Years Old
Every child under four years old riding in a vehicle on a Mississippi public road must be secured in a child passenger restraint device or system that meets federal motor vehicle safety standards. This generally means a rear-facing or forward-facing car seat, depending on the child’s size. Skipping this step can result in a $25 fine.
Children Ages 4 to 6
This is where the Mississippi booster seat law comes into play directly. Children who are at least four years old but under seven must ride in a booster seat unless they already meet a certain height or weight.
Once your child reaches four feet nine inches tall or weighs 65 pounds, Mississippi law allows them to transition out of a booster seat and into a standard seat belt.
When a Seat Belt Alone Is Enough
Once a child turns seven, or reaches 57 inches in height, or hits 65 pounds, whichever happens first, Mississippi law no longer requires a booster seat. At that point, a properly fitted adult seat belt is considered sufficient.
Height and Weight Both Matter
Many Mississippi parents assume age is the only factor, but height and weight can move a child out of booster seat requirements earlier than age seven.
If your child is tall or heavy for their age, they may legally transition to a seat belt sooner. If they are smaller than average, keeping them in a booster longer, even past age seven, is strongly recommended by safety experts.
Best Practices Beyond the Minimum Law
The Mississippi State Department of Health encourages parents to go beyond the legal minimum. A helpful way to check readiness is the five point test.
The Five Point Test
Ask whether your child sits fully back against the seat, whether their knees bend comfortably at the seat edge, whether the shoulder belt crosses between the neck and arm, whether the lap belt sits low on the thighs, and whether they can hold this position for the entire trip. If the answer to any of these is no, keep them in a booster seat.
Back Seat Recommendation
Mississippi recommends children under 13 ride in the back seat, since it offers better protection from front end collisions and airbag deployment.
Fines for Non Compliance
Failing to properly restrain a child under four can lead to a $25 fine. Officers may also cite booster seat violations for children between four and six who do not meet the height or weight exceptions.
Final Thoughts for Mississippi Families
Knowing the Mississippi law for booster seats helps parents avoid fines while genuinely protecting their children on the road. When in doubt, keep your child in a booster seat a little longer rather than moving them to a seat belt too soon.
