Mississippi has the highest traffic fatality rate in the entire nation — more than double the national average per capita — and the car seat law reflects the state’s broader road safety challenges. The statute requires a car seat through age 4 and a booster or seat belt from ages 4 through 7, with a maximum fine of just $25 for the first violation. That’s one of the lowest fines in the country for a state with one of the highest crash fatality rates. I’ve worked with families in Jackson, Hattiesburg, and the Delta region where the nearest car seat inspection station can be over an hour away, and the combination of low fines and limited access to resources creates a dangerous gap.
Mississippi recorded 675 traffic fatalities in 2024, the highest in a decade and more than double the per-capita national average. Over 40% of vehicle occupant fatalities involved unbelted occupants, and rural roads account for the overwhelming majority of fatal crashes. Mississippi’s roads are statistically the most dangerous in the country, making proper child restraint use critically important.
This guide breaks down every requirement in Mississippi’s current child passenger safety law, explains the fines and enforcement rules, covers special situations, and answers the most common questions parents ask.

Mississippi car seat laws by age
Mississippi’s child restraint statute (Miss. Code § 63-7-301) requires appropriate restraints for children through age 7:
Rear-facing (recommended through age 2+): Mississippi law does not specify a rear-facing age requirement. However, the Mississippi Department of Transportation and AAP strongly recommend rear-facing until at least age 2. Most modern convertible seats rear-face to 40–50 pounds.
Car seat with harness (under age 4): Children under 4 must ride in a child restraint device meeting federal standards. A car seat with a five-point harness — rear-facing for infants and toddlers, then forward-facing — is the standard for this age group.
Booster or seat belt (ages 4–7): Children ages 4 through 6 must be in a booster seat or restrained by a seat belt appropriate for the child. Mississippi’s law is less specific than many states on requiring a booster — a seat belt alone is technically permitted for children 4 and older, but safety experts strongly recommend a booster until the belt fits properly (typically around 4’9″).
Seat belt (age 7+): All passengers under 65 must wear a seat belt. Mississippi’s seat belt law applies to front-seat passengers and all passengers under 18.
Back seat recommendation: Mississippi recommends all children under 13 ride in the back seat. This is a safety recommendation, not a legal mandate.
If you’re not sure which seat fits your child’s current stage, our best-rated convertible car seats guide covers every transition from rear-facing infant through booster-ready child.
Fines and enforcement
Mississippi’s child restraint violations carry modest penalties:
First offense: $25 fine.
Subsequent offenses: Up to $100 fine.
Mississippi’s child restraint law is a primary enforcement law — an officer can pull you over solely for observing an improperly restrained child.
No points are assessed on your driver’s license for a child restraint violation.
Special situations
Taxis: Mississippi exempts taxis and for-hire vehicles from child restraint requirements.
Rideshares (Uber/Lyft): Child restraint laws apply to rideshare vehicles. Bring an appropriate car seat when traveling with a child.
Vehicles without back seats: If the vehicle has no rear seat, a child may ride in the front with an appropriate restraint — but never in front of an active airbag in a rear-facing seat.
Leaving a child unattended in a vehicle: Mississippi does not have a specific statute setting a minimum age for leaving a child unattended in a vehicle, but general child endangerment laws apply. Mississippi’s extreme summer heat makes this particularly dangerous.
Smoking in a vehicle with children: Mississippi does not have a law prohibiting smoking in a vehicle with child passengers.
Car seat replacement after a crash: No state law requires it, but NHTSA and all major manufacturers recommend replacing any seat involved in a moderate-to-severe crash.
What to do if you get a ticket
1. Get the correct car seat. Despite the low fine, the real cost of non-compliance is measured in safety — Mississippi’s fatality rate is the highest in the nation.
2. Get it inspected. The Mississippi State Department of Health offers car seat distribution and inspection through local health departments. Safe Kids Mississippi and hospital-based programs in Jackson and other cities also offer checks. You can find a certified technician through the NHTSA technician locator.
3. Bring documentation to court. Proof of compliance can help at your hearing.

Why does Mississippi have such a high traffic fatality rate?

Can I use a secondhand car seat in Mississippi?
Mississippi doesn’t prohibit used car seats, but verify the seat hasn’t been in a crash, isn’t expired, isn’t recalled, and has all original parts. Check the NHTSA recall database. Our guide on what to do with old car seats covers safe disposal options.
