background
In California, if a child is under two years old they need to ride in a rear-facing car seat. The only exception is if they weigh 40 pounds or more or are 40 inches or taller. Children under the age of eight need to be safely secured in a car seat or booster seat in the backseat.
According to the National Highway Traffic Safety Administration (NHTSA), proper use of the right child car seats will significantly reduce the risk of fatal injuries in small children. Incidentally, if you’re driving with your children who are not in a car seat or booster seat, you are putting them at risk and could face penalties if caught. 
We can help you understand how to safely drive with your small children in California, what happens if you don’t follow the booster seat laws, and how to protect your family with the right coverage.

What is the booster seat law in California?

California car seat law
mandates that all children under two years old must ride in a rear-facing seat. This only applies to children who weigh less than 40 pounds or are shorter than 40 inches. 
California seat belt law
also stipulates that children under eight years old have to be safely secured in either a car seat or booster seat in the backseat of the vehicle. 
California does not consider graduation time when outlining when your child should move from car seats to other safety seats. This can be really stressful. To help, review this table that breaks down how to secure your child before you start driving:
Seat type
Age limit
Child weight and/or height
Infant seat (rear-facing)
Newborn to two-years-old
40 pounds or more
Toddler seat (forward-facing)
Two years until they outgrow seat
40 and 65 pounds
Booster seat
N/A
Between 40 and 80 pounds/under 4’9’’ tall
Seat belt
N/A
165 pounds
It’s usually recommended to tailor your child’s car seats to their height and weight, not their age. Furthermore, it’s best if children continue sitting in their booster seats until they can be comfortably secured by adult-sized seatbelts. 
Key Takeaway Children under two years old must ride in a rear-facing seat (if less than 40 pounds or under 40 inches tall). Children under eight years old must be safely secured in either a car seat or booster seat.

How breaking booster seat laws can impact insurance in California

A booster seat violation will be noted by your insurance company and you may have to pay more every month. If your violation puts points on your driving record, your rates will most likely be increased by your
