The Short Answer: California’s Car Seat Rules by Age, Height, and Weight
Under California Vehicle Code § 27360, children must generally ride in an appropriate child passenger restraint system until they reach age eight or a height of 4 feet 9 inches.
California’s requirements include:
- Under age two: Children must ride rear-facing unless they weigh at least 40 pounds or measure at least 40 inches tall.
- Under age eight: Children must generally use an appropriate car seat or booster seat in the back seat, unless they are at least 4 feet 9 inches tall.
- Ages eight and older: Children may use a properly fitted seat belt, although a booster seat may still be safer.
- Under age 16: All passengers must be properly restrained using an appropriate seat belt or child restraint system.
Parents should also follow the car seat manufacturer’s height and weight limits.
Rear-Facing, Forward-Facing, and Booster Seat Requirements
California law establishes minimum requirements, but safety experts recommend keeping children in appropriate restraints as long as possible.
Rear-Facing Seats
Rear-facing car seats support a child’s head, neck, and spine during a collision.
California generally requires children younger than two to remain rear-facing unless they meet the statutory height or weight exception.
The National Highway Traffic Safety Administration (NHTSA) recommends keeping children rear-facing until they reach the maximum height or weight allowed by their car seat manufacturer.
Forward-Facing Seats With a Harness
Once children outgrow their rear-facing seats, they can transition to forward-facing seats with harnesses.
These seats help distribute crash forces across stronger parts of the child’s body.
Children should remain in forward-facing seats with harnesses until they reach the manufacturer’s height or weight limits.
Booster Seats
Booster seats elevate children so adult seat belts fit correctly across their shoulders, chest, and hips.
Children generally need booster seats until they are tall enough for adult seat belts to fit properly.
Even after turning eight, children shorter than 4 feet 9 inches may benefit from continued booster seat use.
When Can a Child Sit in the Front Seat in California?
California generally requires children younger than eight who are under 4 feet 9 inches tall to ride in the back seat.
Certain exceptions apply, including when:
- The vehicle has no rear seat.
- All rear seats are occupied by children seven years old or younger.
- The rear seats cannot safely accommodate a child restraint.
- A medical condition requires different seating arrangements.
Children eight and older may legally sit in the front seat with appropriate restraints. However, safety experts recommend keeping children younger than 13 in the back seat whenever possible. California also prohibits placing a rear-facing child restraint in the front seat of a vehicle equipped with an active frontal passenger airbag.
Penalties for Violating California’s Car Seat Law
Violating California’s child passenger safety laws can result in fines, court fees, and other penalties. The consequences may depend on whether it is a first or subsequent violation.
In some cases, drivers may also be required to complete a child passenger safety education program. Following California’s car seat requirements can help families avoid penalties while keeping children safer on the road.
Does a Car Seat Violation Affect a Child’s Injury Claim?
A car seat violation does not automatically prevent an injured child from recovering compensation after an accident.
California follows a pure comparative negligence system, meaning compensation may be reduced based on an injured person’s share of responsibility.
However, a parent’s failure to properly restrain a child generally cannot be used to assign the parent’s negligence to the child.
Liability depends on the circumstances, including what caused the collision and whether improper restraint contributed to the injuries.
Should You Replace a Car Seat After an Accident?
The NHTSA recommends replacing car seats following moderate or severe crashes.
Replacement may not be necessary after a minor collision if specific safety criteria are satisfied.
Parents should inspect the manufacturer’s instructions and contact their insurance company about potential replacement coverage.
