Louisiana uses age-based child restraint stages, including rear-facing under 2, forward-facing after rear-facing limits, and belt-positioning booster use for children at least 4 who have outgrown the forward-facing seat.
Louisiana booster seat law: a child moves to a booster at age 4 after outgrowing the forward-facing seat
Louisiana's rule is built around stages rather than one cutoff. A child under 2 rides rear-facing until reaching the rear-facing seat's height or weight limit. From age 2, once those limits are reached, the child moves to a forward-facing seat with an internal harness. From age 4, once the forward-facing limits are reached, the child moves to a belt-positioning booster secured with a lap-and-shoulder belt.
Two extra rules matter for everyday trips: a child under 13 should ride in a rear seat when one is available, and if a child fits more than one category, the more protective category applies.
Front seat rule: Children under 13 must ride in a rear seat when one is available. See front seat age by state for all 50 states.

Louisiana booster seat law 2026 update
Louisiana deserves a clear 2026 section because its law uses several stage changes that parents can easily mix up.
The state law is stage-based: under 2 rear-facing until the rear-facing seat limit, at least 2 and past rear-facing limits in a forward-facing internal-harness seat, and at least 4 and past forward-facing limits in a belt-positioning booster secured with a lap-and-shoulder belt.
Louisiana also says a child under 13 should ride in the rear seat when a rear seat is available, and if a child fits more than one category, the more protective category applies.
Stages
Why Louisiana's booster seat rule is written in stages
Most parents want a single age. Louisiana does not give one, and the reason is practical: a seat is outgrown by size, not by birthday. Each Louisiana stage has two conditions joined together — the child has reached a minimum age, and the child has outgrown the previous restraint's height or weight limit.
That means a 4-year-old who still fits inside the forward-facing seat's harness limits does not automatically move to a booster. The harness is the more protective option while it still fits, and Louisiana's "more protective category" rule points the same direction.
The practical way to use this page is to check the label on the seat you currently own. The height and weight limits printed on that label are what decide when the next stage starts.
Booster stage
When a Louisiana child moves into a belt-positioning booster
The booster stage starts when the child is at least 4 and has reached the forward-facing seat's height or weight limit. Louisiana ties the booster to a lap-and-shoulder belt, which matters because most belt-positioning boosters are not designed for a lap-only belt.
Louisiana does not put a single booster-exit height in the statute the way some states do. That makes belt fit the working test. The lap belt should stay low across the upper thighs, and the shoulder belt should cross the middle of the shoulder and chest, for the whole ride rather than just at the start.
If a seating position only has a lap belt, check the booster manual and consider a different position in the vehicle.
Rear seat
Louisiana's under-13 rear seat rule
Louisiana's law says a child under 13 should ride in a rear seat when a rear seat is available. This sits alongside the restraint stages rather than replacing them: a 6-year-old in a booster is still expected in the back.
The rule is written around availability, so vehicles without a usable rear seat are a different situation. Check Louisiana Revised Statutes 32:295 for the specific wording before relying on a front-seat placement.
Adult claims
Does Louisiana have a new adult booster seat law?
This page found a child passenger restraint law, not a separate adult booster seat requirement. Louisiana's rule is written around children: rear-facing under 2, forward-facing from 2, boosters from 4, and rear-seat placement under 13.
Claims circulating about a new state requirement for adults under a certain height are not this child passenger law. Treat any such notice as unverified unless it links to an official Louisiana statute or state agency page.
Shorter adults may still choose belt-positioning aids or vehicle adjustments for comfort and fit, but that is a personal choice rather than a Louisiana booster seat law. Searches using the phrase "adult booster seat" usually mean the point at which a child can move from a booster to the adult belt.
Fines
Louisiana booster seat penalties and source verification
Check the current Louisiana statute and local court costs for penalties before relying on a dollar amount.
Penalty amounts are the part of a state child passenger law most likely to be quoted incorrectly online, because court costs and local fees sit on top of any statutory figure. For Louisiana, use the statute and current state agency materials rather than a summary when the exact dollar amount matters.
The safety reason to fix the restraint is larger than any ticket. A harness or booster that matches the child's current size is what keeps crash forces on the strongest parts of the body.
Parent scenarios
Louisiana booster seat questions parents usually mean
My child just turned 4. Do we switch to a booster now?
Not automatically. The booster stage starts when the child is at least 4 and has outgrown the forward-facing seat's height or weight limit. While the harness still fits, it is the more protective option.
Can a 3-year-old use a booster?
Louisiana's booster stage begins at age 4. A younger child belongs in a forward-facing seat with an internal harness, or rear-facing if the rear-facing limits have not been reached.
Does my 10-year-old have to sit in the back?
Louisiana says a child under 13 should ride in a rear seat when one is available, so yes in a typical vehicle.
What if my child fits two categories?
Louisiana's law answers this directly: use the more protective category. In practice that usually means staying in the current seat rather than moving up early.
