How Long Does a Child Need a Car Seat in Florida?

In Florida, a child needs a car seat or booster through age five under the current law, and starting July 1, 2026, the requirement extends through age eight unless the child is at least 4 feet 9 inches tall. So the short answer to how long a child needs a car seat in Florida depends on when you’re asking: right now it ends at the sixth birthday, but under House Bill 233 it will run until age nine or until your child hits that height mark, whichever comes first.

Current Rule Through June 30, 2026

Florida Statute 316.613 requires every child aged five or younger to ride in a crash-tested, federally approved child restraint on any public road in the state.¹ The type of restraint depends on the child’s age:

Birth through age 3: a separate carrier or the vehicle manufacturer’s integrated child seat.
Ages 4 and 5: a separate carrier, an integrated child seat, or a booster seat.

For a four- or five-year-old, a booster counts, but a regular seat belt on its own does not (with a few narrow exceptions covered below). Once a child turns six under the current law, Florida no longer requires a child restraint, and a standard seat belt satisfies the statute.

New Rule Starting July 1, 2026

House Bill 233 extends Florida’s booster requirement to children ages six through eight. Starting July 1, 2026, a child in that age range must ride in a booster seat unless they stand at least 4 feet 9 inches tall. A child who has reached that height can use a standard seat belt instead. This is the first time Florida has pushed its child restraint requirement past age five.

If you have a six-, seven-, or eight-year-old who currently rides with just a seat belt, measure them before next July. If they’re under 4’9″, you’ll need a booster in the car by the effective date. The rules for children five and under, and the penalties for violations, do not change.

When Your Child Is Actually Big Enough for a Seat Belt

The 4-foot-9 mark isn’t arbitrary. It’s the widely used benchmark for when a vehicle seat belt fits a child correctly on its own, and it’s the height Florida wrote into the 2026 law. But height is a shortcut. Child passenger safety technicians use a five-step fit test to make the real call:

The child’s back sits flat against the vehicle seat back without slouching.
Their knees bend naturally at the edge of the seat cushion.
Both feet rest flat on the vehicle floor.
The lap belt lies low across the upper thighs and touches the hip bones, not the stomach.
The shoulder belt crosses the middle of the chest and collarbone, sitting between the neck and the shoulder.

If your child fails any one of these, they still need a booster, legally required or not. A lap belt riding up on the abdomen can cause serious internal injuries in a crash, and a shoulder belt that cuts across the neck usually ends up tucked behind the child’s back, which removes any protection at all. NHTSA notes that most children need a booster until somewhere between ages 9 and 12 before a seat belt fits properly on its own.²

Exemptions Parents Often Ask About

The statute carves out a handful of situations where children ages four and five can use a seat belt instead of a child restraint. These do not apply to children three and under, and the child still has to be belted:

A free ride from someone outside the child’s immediate family.
A medical emergency involving the child.
A medical condition that makes a car seat impractical, documented in writing by a physician.

Taxis and Rideshares

Florida exempts chauffeur-driven vehicles used for paid transportation from the child restraint requirement entirely, including taxis, limousines, sedans, vans, buses, and motor coaches for hire.¹ An Uber or taxi driver won’t be ticketed for a missing car seat, and the statute places responsibility for child safety on the parent or guardian. Legal permission is not the same as safety, though. If you regularly use rideshares with young kids, a portable booster or travel car seat solves the problem.

Penalties for a Violation

Driving with an improperly restrained child is a moving violation. The fine is $60, plus three points on the driver’s license.³ Points stack with anything else already on your record and can move you toward a suspension.

First-time offenders have an alternative. With the court’s approval, you can attend a child restraint safety program approved by the Department of Highway Safety and Motor Vehicles. If you complete it, the court can waive the fine, associated court costs, and the point assessment.¹

One more practical note. The seat you use should match your child’s current weight and height according to the manufacturer’s guidelines, not just their age. Florida’s statute sets the floor for when a restraint is legally required; it does not tell you which type of seat is right for the child in front of you. That call comes from the seat’s own limits and how your child fits it today.
