Rear-Facing Car Seat Law Mississippi

There is no legal specification for how long a child must remain in a rear-facing car seat in Mississippi.

Mississippi law only states that children under 4 years old must be secured in a car seat (with a separate harness system).

However, the state does provide safety guidelines for when you should use a rear-facing car seat.

Rear-Facing Car Seat Guidelines Mississippi

Mississippi recommends keeping children rear-facing until they reach ONE of the following requirements:

  • Rear-Facing Car Seat Age: 2 years
  • Rear-Facing Car Seat Weight: determined by manufacturer
  • Rear-Facing Car Seat Height: determined by manufacturer

Mississippi does not provide a weight or height limit for when children should move from a rear-facing to a forward-facing car seat.

Instead, the state recommends you secure your child in a rear-facing seat until the child reaches the height or weight limit on the particular car seat or until at least age 2.

Forward-Facing Car Seat Law Mississippi

Children must ride in a front-facing (or rear-facing) car seat in Mississippi until they reach ONE of the following requirements:

  • Forward-Facing Car Seat Age: 4 years
  • Forward-Facing Car Seat Weight: unspecified
  • Forward-Facing Car Seat Height: unspecified

Mississippi does not provide a weight or height limit for when children should move from a front-facing car seat to a booster seat.

As soon as a child reaches 4 years of age, it’s legal for the child to ride in a booster seat.

The state recommends, however, that you secure your child in a front-facing car seat until the child reaches the height or weight limit on the particular car seat.

Where can I get my car seat checked or installed in Mississippi?

The University of Mississippi Medical Center (UMMC) operates a car seat inspection station in Clinton.

And Children’s of Mississippi (part of UMMC) is the lead agency for Safe Kids in the state.

When were car seats invented?

Two precursors to car seats as we know them today were both invented in 1962. (Though, they weren’t available until the late-60s.)7a9cd5ef a9f7 4cf7 92cb 76d8e96f2c63

The first of these seats, and the one most similar to the car seats we use today, had a Y-shaped harness and was rear-facing.

The seat was invented by British inventor (and mother) Jean Ames.

The second of these seats was metal-framed seat designed to face forward, and was invented by American inventor Leonard Rivkin.

Before that, the only type of child seat for cars were booster-style car seats, which simply lifted children higher in the seat, but had no safety features and had been manufactured since the 1930s.

When did car seats become mandatory?

Car seats became mandatory between 1978 and 1986.

Though car seats were available in the late 1960s, and the data showing their effectiveness was available in the early 1970s, they remained optional safety devices, and most parents didn’t opt to use them.

So, it became a matter of enacting laws.

In the U.S., car seats became mandatory as most things do – on a state-by-state basis.

In 1978, Tennessee became the first state to enact a child restraint law of any kind (the law passed in 1977), a successful campaign that prompted other states to follow suit.

Over the next few years, all U.S. states passed and implemented child restraint laws, with all states enacting laws by 1986.

Who is responsible for child restraint laws in the U.S.?

While there were experts and activists all over the country working to pass child restraint laws, Dr. Robert Sanders and his wife Pat are largely credited with getting the first Tennessee law passed.

Dr. Sanders was a pediatrician and he and his wife lobbied for the legislation for years.

Dr. Sanders even got a moniker out of his activism.

He became affectionately known as “Dr. Seat Belt.”

Car Seats Save Young Lives

Car seats are designed to protect the smallest, most vulnerable of children, and, since car seat rules first went into effect nationwide in the mid-1980s, they have done a stellar job at saving kids’ lives.

That’s why car seats are required in every state in the U.S. up to a certain age (with some states also having booster and front seat laws), and why the American Academy of Pediatrics and CDC recommend using some form of child restraint system in vehicles until children are big enough to be protected by a car’s built-in safety features (4’9”).

So, definitely follow Mississippi’s car seat laws to protect the smallest of children.

And continue to follow the booster and front seat laws (or expert guidelines) to ensure your child is well-protected on the road.
