California child car seat laws require every child under eight to ride properly buckled into a federally approved car seat or booster in the back seat of the vehicle, with a stricter rear-facing rule for children under two. A child who reaches four feet nine inches may use a standard seat belt before turning eight. Responsibility for compliance falls on the parent or legal guardian when they are in the vehicle, and on the driver when they are not.1California Legislative Information. California Code VEH 27360 – Child Safety Belt and Passenger Restraint Requirements
The Rule for Children Under Eight
Vehicle Code Section 27360 covers every child under the age of eight riding in a motor vehicle on a California road. The child must be secured in a child passenger restraint system that meets federal motor vehicle safety standards, and the seat must be used within the manufacturer’s height and weight limits.1California Legislative Information. California Code VEH 27360 – Child Safety Belt and Passenger Restraint Requirements Adult seat belts are built for adult bodies; a car seat or booster is what actually protects a small child in a crash.
Children under eight also have to ride in the rear seat. Exceptions exist, and they are listed further down.
Rear-Facing Until Age Two
Children under two must ride in a rear-facing car seat.1California Legislative Information. California Code VEH 27360 – Child Safety Belt and Passenger Restraint Requirements Rear-facing seats support the head, neck, and spine during a collision in a way that forward-facing seats cannot for a child that small.
Two size-based exceptions let a child under two ride forward-facing: weighing 40 or more pounds, or standing 40 or more inches tall.1California Legislative Information. California Code VEH 27360 – Child Safety Belt and Passenger Restraint Requirements The child still has to be in a car seat that complies with the manufacturer’s height and weight ranges.
One rule has no exception. A child in a rear-facing seat may never ride in front of an active passenger airbag.2California Legislative Information. California Code VEH 27363 – Child Passenger Restraint Exemptions A deploying airbag can be fatal to an infant.
When a Child Can Move to a Seat Belt
A child does not have to stay in a car seat or booster until their eighth birthday if they grow tall enough first. Vehicle Code Section 27363 allows a child under eight who is at least four feet nine inches tall to use a standard vehicle safety belt.2California Legislative Information. California Code VEH 27363 – Child Passenger Restraint Exemptions At age eight, the car seat requirement ends regardless of height.
Height alone does not guarantee a safe fit. The law describes a five-point check for whether a seat belt is doing its job on a child:2California Legislative Information. California Code VEH 27363 – Child Passenger Restraint Exemptions
- The child sits all the way back against the vehicle seat.
- Their knees bend naturally over the seat edge.
- The shoulder belt crosses the center of the chest and shoulder, not the neck.
- The lap belt sits low and touches the thighs, not the stomach.
- The child can stay in that position for the entire ride.
If a child clears four feet nine inches but fails any of these, keep the booster.
When a Child Can Ride in the Front Seat
A child under eight may ride up front, properly restrained in a car seat, only in specific situations:2California Legislative Information. California Code VEH 27363 – Child Passenger Restraint Exemptions
- The vehicle has no rear seat, as in many pickups and two-seaters.
- The rear seats are side-facing jump seats or rear-facing.
- The car seat cannot be properly installed in the rear.
- All rear seats are already occupied by children age seven or younger.
- A medical condition requires the child to ride in front, and the court may ask for proof.
Even then, no rear-facing seat in front of an active passenger airbag. Ever.
Other Exemptions and Where There Are None
A court can grant an exemption from the car seat requirement when a child’s physical condition, medical needs, or size make a standard restraint impractical. The court may require a physician’s statement and will consider whether a special-needs restraint is available before granting it.2California Legislative Information. California Code VEH 27363 – Child Passenger Restraint Exemptions
During a genuine life-threatening emergency, or when a child is riding in an authorized emergency vehicle, the child may travel without a car seat but still has to wear a seat belt. A child over 40 pounds may use just a lap belt in a rear seating position that lacks a combination lap-and-shoulder belt.2California Legislative Information. California Code VEH 27363 – Child Passenger Restraint Exemptions
There is no exemption for taxis, rideshare trips, or rental cars. A child who needs a car seat in your own vehicle needs one in an Uber too.
Fines and Other Consequences
A child restraint violation is a primary offense in California, so an officer can pull you over for that alone. Under Vehicle Code Section 27360.6, the base fine starts at $100 for a first offense and $250 for a second or subsequent one.3California Courts. Uniform Bail and Penalty Schedules
The base fine is not what you actually pay. California adds penalty assessments, surcharges, and court fees to every traffic fine, which pushes a $100 base fine to roughly $490 total.3California Courts. Uniform Bail and Penalty Schedules A repeat offense climbs higher still.
For a first offense, the court may reduce or waive the fine on a showing of economic hardship. In that case, the court typically orders a community education program on car seat installation and use, with proof of completion required. A conviction also adds a point to your California DMV driving record, which can affect your insurance rate.
Ages Eight Through Fifteen
The car seat statute ends at age eight, but the restraint requirement does not. Vehicle Code Section 27360.5 makes it illegal to transport a child between eight and fifteen without a proper seat belt or child restraint system.4California Legislative Information. California Code VEH 27360.5 – Child Passenger Restraint System A standard seat belt is enough for this age range as long as it fits correctly. The same rule on who is responsible applies: if the parent or guardian is a passenger but not driving, the driver carries the violation.
What to Do With the Car Seat After a Crash
After a moderate or severe collision, the National Highway Traffic Safety Administration recommends replacing every car seat that was in the vehicle, even one that looks fine. Damage inside a seat can be invisible and still reduce protection the next time.5National Highway Traffic Safety Administration. Car Seat Use After a Crash
NHTSA treats a crash as minor, and keeps the seat eligible for reuse, only when all five of these are true:5National Highway Traffic Safety Administration. Car Seat Use After a Crash
- The vehicle was drivable from the scene.
- The door closest to the car seat was not damaged.
- No one in the vehicle was injured.
- No airbags deployed.
- The car seat has no visible damage.
Miss any one of those and replace the seat. If you carry collision coverage, your auto insurer will usually reimburse you for an equivalent replacement; give them the make and model when you file the claim.
Getting Help With Installation
Correct installation is harder than it looks, and installation errors are common. The California Highway Patrol has certified child passenger safety technicians at its area offices across the state who will check your seat or help you install it, free of charge.6California Highway Patrol. Child Safety Seats Call your local CHP office to find out when they’re available. Many fire stations and hospitals in California run free inspection events as well.
